The AEL Techno System DHW Packaged Plate Heat Exchangers can be programmed to thermally scour the DHW circuit by using our Anti Legionella bypass valves with a two way valve that eliminates legionella and isolates the DHW outlet whilst avoiding any scalding during the Anti Legionella cycle. 

The AEL Techno System Anti Legionella function can be programmed with 64 settings with a visual message on the display in case of probe malfunction or an optional audible alarm can be provided.

The four main factors that influence the growth of legionella are. 

1. TEMPERATURE 
2. WATER FLOW / STAGNATION 
   
3. PARTICULATE MATTER
   
4. NUTRIENT SUPPLY

 

 TEMPERATURE 
1. Legionella exists in low numbers when the temperature is below 20°C
2. Between 20°C and 37°C the growth is rapid and slows down as it reaches 45°C
3. At 50°C 90% of legionella dies off within two hours and at 60°C legionella are killed off within two minutes. 

WATER FLOW STAGNATION
Low or no flow rate of a fluid may cause stagnation which will encourage the growth of legionella.  

PARTICULATE MATTER
Particulate matter may offer protection to the legionella bacteria where they may be killed off in adverse conditions. 

NUTRIENT SUPPLY
Common organisms such as bacteria serve as a nutrient for legionella. 

USING A  PLATE HEAT EXCHANGER TO REDUCE THE RISK OF LEGIONNAIRES DISEASE
Because a Plate Heat Exchanger instantaneously heats up fluids and does not have any storage, they practically eliminate the possibility of any dangerous bacteria growth such as legionella. 

A standard AEL Plate Heat Exchanger can heat up domestic hot water from 10°C to 60°C instantaneously at a continuous flow rate of 5 L/S. 

The AEL Plate Heat Exchanger plates are made from 316 Stainless Steel that has a corrugated profile that creates turbulence as the fluid flows through the unit which also scrubs and also helps to reduce any particulate deposits forming on the plates. 

It is worth noting that using a plate heat exchanger can practically eliminate legionella from the most common sources which have been found to be: 

1. COOLING TOWERS and EVAPOURATOR CONDENSERS. 
2. HOT WATER SYSTEMS 
3. HUMIDIFIERS and AIR WASHERS 

 

A GUIDE ON HOW TO MANAGE THE RISK OF LEGIONELLA
It is important that every installation has a well thought through scheme to prevent or minimise the risks of legionella. 
It is important that a responsible person is employed to manage and implement precautions. 
It is important that records are kept of the precautions taken.

The practice among some manufacturers and suppliers in the UK of using unrealistic sizing tolerances when designing Plate Heat Exchangers to offer a cheaper option at quotation stage creates uncertainty about the actual performance of the heat exchanger design provided, leading to higher operating costs for the end customer.

AEL and Alfa Laval are committed to raising awareness about the problem and are highlighting the solution of using the AHRI Performance Certification as a means of guaranteeing that each Plate Heat Exchanger we design performs exactly as expected.

The stated performance of some Plate Heat Exchanger suppliers in the UK does not always live up to expectations. For many years, it has been a common, albeit hidden, practice in the industry for some suppliers of Plate Heat Exchangers to overstate the actual duty calculations when sizing their heat exchangers to offer a cheaper alternative. This is currently the biggest problem facing the Plate Heat Exchanger industry in the UK today, and the Specifying Engineers that pride themselves in producing well‑designed installations need to be made aware that there is a solution.

Heat duty calculation is an important step in the specification process and is essentially an assessment of the requirements for maximum performance by the consultant and designer of the heating or cooling system. “Adjusting” these calculations has become a weapon of deception in the battle to win contracts. Manufacturers manipulate calculations so that component costs can be minimized and a smaller plate heat exchanger can be offered at an attractive price. However, the result is that end customers get under‑dimensioned heat exchangers, leading to higher system‑wide energy use, higher operating costs, and compromised environmental performance.

The widespread practice of “recalculation” is a big problem for everyone in the industry. It makes it harder to choose a heat exchanger that will provide the required performance and increases the risk that it will underperform. It creates uncertainty for everyone involved in recommending, selecting, and using heat exchangers – consultants, specifiers, and end customers – and undermines confidence in the industry.

By the time the problem is detected, it is too late – a major investment has already been made, and the underperformance can only be revealed in the higher‑than‑expected energy costs to the end user.

The only way to ensure the quality of the materials being used and the thermal design is accurate from the start is to specify AHRI Approved Plate Heat Exchangers. Such is the belief and commitment of AEL and Alfa Laval to Performance Certification in the UK that we provide a 3‑year warranty with all our AHRI Approved Plate Heat Exchangers.

The Air‑Conditioning, Heating, and Refrigeration Institute (AHRI) is the only independent third‑party nonprofit organization that certifies the performance and materials used in Plate Heat Exchangers globally. The AHRI Liquid to Liquid Heat Exchangers (LLHE) Certification Program provides third‑party verification of thermal performance and materials used – it gives independent assurance that the plate heat exchanger you have been quoted will perform in accordance with the manufacturer’s published ratings and has been designed with a reasonable sizing tolerance.

Independent Performance Certification creates a level playing field for comparing the thermal performance and price/performance ratio of plate heat exchangers, which reduces time spent on the selection process and ensures the optimum product is chosen. End users benefit from operating a more energy‑efficient system with optimized energy consumption and significantly reduced lifetime operating costs. As calculations have already been verified, costs are lower for field tests and additional component performance margins. It also enables end users to reach targets for power consumption and climate control, as they can be confident that heat exchanger capacity will be sufficient to meet set performance goals.

AHRI Performance Certification eliminates cheating from overstating thermal performance for financial gain, which enhances confidence in the industry and provides peace of mind for those who rely on system performance – suppliers, consultants, contractors, and end users. In the longer term, performance certification will eliminate concern about calculations and promote a stronger focus on energy efficiency, which will foster innovation and stimulate manufacturers to develop more efficient products.

AEL and Alfa Laval believe in the AHRI certification, and the AHRI LLHE Certification Program is currently the only program available in the world for Plate Heat Exchangers.

The Alfa Laval AlfaQ series were the first to be AHRI certified, and Alfa Laval has accomplished a 100% success rate in the AHRI Performance Certification Program since the start. AEL and Alfa Laval have chosen to take an active role in promoting AHRI certification. From every perspective, AHRI Performance Certification is better for everyone involved in the process of designing, producing, selecting, and operating plate heat exchangers.

AEL and Alfa Laval are convinced that the AHRI Performance Certification is an important step in creating a sound Plate Heat Exchanger market in the UK that benefits the whole industry and the end users that have trust in our expertise when designing a Plate Heat Exchanger for their application.

Should you have a project where you would prefer to have guaranteed performance certification, please contact AEL and we will be delighted to provide you with a quotation, specification data sheets, and a drawing of your Alfa Laval AHRI Approved Plate Heat Exchanger.

Using BIM gives Construction Professionals the confidence of knowing that the specified equipment is suitable for the space provided with other components and that the technical information that is automatically provided ensures the equipment will operate as required.

BIM is not CAD, CAD is a drafting tool to create representational lines and arcs whereas BIM provides a rotational digital 3D image of the specified equipment or component that is supported with technical information such as size, height, weight, flow rate, temperature etc.

The use of BIM has been mandatory for public construction projects since 2018 and in all infrastructure projects during July 2019 and the pace of change has meant that most UK Architects and Professional design engineers are all using BIM with the numbers dramatically increasing each year.

In many countries, the use of BIM is mandatory for new building and infrastructure projects. These include Australia, Brazil, Czech Republic, Chile, Denmark, Finland, Japan, Kazakhstan, Latvia, Norway, Singapore, South Korea, the United Kingdom, Ireland and Vietnam.

One very popular feature of BIM is the BIM viewer that allows you to walk through your design. It is not always easy to explain a building plan with clarity to your client with technical drawings even if you completely understand the project, but being able to virtually walk clients through every room in a 3D building and see every fixture and component in place is a great asset when presenting a project.

If you are installing a heat pump or another renewable energy low water temperature heat source into a new system using your existing radiators then you must check the heat required for the room matches the KW output of your radiator at a lower water temperature.

The general rule is that if the radiator outputs in an older central heating system were sized using a boiler supplying water at 82 oC and the new Heat Pump system or Renewable Energy System has a water temperature of 35 oC then your existing radiator surface area may well not be sufficient to warm the room.

HOW TO FIND THE OUTPUT REQUIRED FOR YOUR ROOM

After using the “Easy heat guide for your room” shown at the bottom of each radiator page on the AEL website you now know the heat required for your room so you can now check that the FARAL Aluminium radiators you have chosen will provide enough heat output.

HOW TO CHOOSE THE CORRECT RADIATOR SIZE

Once you know the output required for your room and the model of the radiator you prefer there is a simple calculation to check if the radiator you have chosen will provide sufficient heat output for your room by checking the “Delta T”, please see below:

HOW TO CALCULATE THE DELTA T OF A RADIATOR

The FARAL Aluminium radiator brochure provides a standard heat output figure based on a flow temperature out of the gas boiler of 80 oC which gives an overall delta t of 50 oC.

Using an 80 oC water flow in temperature, and a 60 oC water flow out temperature the average temperature in the centre of the radiator is 70 oC.

If we take away the average room temperature of 20 oC from the 70 oC average temperature across the radiator we are left with a Delta T of 50.

REDUCED WATER TEMPERATURE WHEN USING A HEAT PUMP

The water flow temperature from your Heat Pump to the central heating system is a far lower water temperature than if it was supplied from a gas boiler so you will need to calculate a new output figure by multiplying the output figure shown in the catalogue LINK by a figure shown on the correction chart below.

If the “Delta t” in the catalogue is 50 oC and your system “Delta t” is 50 oC then the correction factor is = 1 on the chart below which means it is perfect so just use the outputs shown in the catalogue.

If the system “Delta t” is more or is less than 50 oC then look at the actual system temperature on the left hand side of the chart and multiply the output shown in the catalogue by the factor shown on the right hand side of the chart, this will give you your new output for the radiator.

When mixing valves are used at each tap or shower outlet in a DHW system the KW demand can be reduced because the PHE water at 60 oC is automatically blended through a mixing valve with mains cold water at 10 oC to arrive at a pre determined temperature of say 40 oC (as shown below) at the outlet of a shower or tap when required .

The temperature on each DHW circuit outlet can be adjusted at the mixing valve by altering the percentage of hot and cold water mixed to suit whatever is required at each appliance on site.

Each AEL domestic hot water Plate Heat Exchanger whether it is an AEL fully controlled Packaged unit , Brazed Plate or Plate and Gasket type heat exchanger each can be made to suit the temperature you require but most DHW systems are designed to supply water at 60 oC to avoid the growth of legionella .

The designs shown below are based on a flow rate of 60% of DHW from a Packaged Plate Heat Exchanger at 60 oC being mixed with 40% of mains cold water at 10 Oc giving an outlet temperature of 40 oC.

Domestic Hot Water (DHW) Plate Heat Exchangers can be supplied as a Plate / Gasket unit or supplied as a Brazed Plate unit

The post REDUCING THE KW OUTPUT REQUIRED FROM YOUR PLATE HEAT EXCHANGER WHEN USING MIXING VALVES ON TAPS & SHOWERS appeared first on AEL Heat Exchangers.

All AEL Plate Heat Exchangers are designed to instantaneously supply the required flow of water and most other fluids at a pre determined set point temperature within a 1 or 2 degree tolerance for your project.

Should the system design change in future the plate and gasket plate pack can be redesigned by removing, adding or changing the plate pack within the frame.

The brazed plate heat exchanger plates are a fixed design that can only be changed by increasing or decreasing the flow rate, temperature on either Primary or Secondary circuits or by increasing or decreasing the Primary KW input but not by changing the plates.

DOMESTIC HOT WATER (DHW) PLATE HEAT EXCHANGERS

Domestic Hot Water (DHW) Plate Heat Exchangers can be supplied as a Plate / Gasket unit or supplied as a Brazed Plate unit. In practice both types of heat exchanger transfers energy from hot or cold fluid and ensures that the Primary circuit does not mix with the Secondary circuit therefore creating two completely independent separate heating or cooling circuits.

When close control is required in a system that has limited temperature control it is common practice to install an AEL Packaged Plate Heat Exchanger with integral controls in a DHW application as the temperature needs to be controlled properly so as not to scald anybody using a tap or shower.

USING PLATE HEAT EXCHANGERS AS A CENTRAL HEATING SYSTEM BREAK

Using an AEL Plate heat exchanger as a central heating system break to protect an expensive piece of equipment such as a Boiler or Chiller is a very common practice.

AEL Plate Heat Exchangers are used in these applications to separate the Central Heating system into two circuits, one Primary circuit dedicated to the boiler which in turn heats up the Secondary circuit that feeds the radiators and associated heating or cooling equipment.

The general idea of the Central Heating System Break is to separate the heating into two circuits so that any deposits floating around an old heating system will not damage or shorten the life of the expensive boiler & associated equipment .

FULLY CONTROLLED PACKAGED PLATE HEAT EXCHANGERS

Systems requiring an AEL Packaged Plate Heat Exchangers usually require very close temperature control. These units are skid mounted and can be fully or partially controlled c/w control panel, pumps, diverting valves and control thermostats.

Applications – usually used for Domestic Hot Water (DHW), Swimming Pools (SP) or can be a Bespoke Plate Heat Exchanger specifically designed for ypur application.

BRAZED PLATE HEAT EXCHANGERS

Brazed plate heat exchangers are very compact and can operate in pressures exceeding 30 bar.

Brazed Plate Heat Exchangers do not have bolts or frame so they cannot be opened up for any necessary cleaning which will need to be done by circulating chemicals around the plates.

The number of plates on a Brazed plate heat exchanger plates are fixed which means that the design duty can only be changed by increasing or decreasing the flow rate, temperature or primary KW input.

PLATE AND GASKET HEAT EXCHANGERS

The advantage that a Plate and Gasket type heat exchanger has over a Brazed type is that they do come with bolts within a frame and can be opened for servicing / cleaning or to alter the number of plates to change the performance / duty at a later date by increasing or decreasing the flow rate, temperature or primary KW input.

Plate and gasket heat exchangers are suitable as Central Heating System Breaks, direct Domestic Hot Water (DHW) supply, Swimming Pools and most other applications.

SWIMMING POOL PLATE HEAT EXCHANGERS

AEL Swimming Pool Plate Heat Exchangers must be robust and purpose made to cope with the corrosive atmosphere and water in a swimming pool environment.

The AEL  fully controlled packaged Swimming Pool Plate Heat Exchangers tend to be most popular with medium to larger new build pools. Whilst the Bare Plate Heat Exchangers (excluding controls) are also popular with new build but they are more popular as replacements for older equipment that have failed as they can easily be incorporated into an existing system to operate within the design of the existing pumps and controls.

Most Plate Heat Exchanger Designs for Central Heating, Domestic Hot Water and Swimming Pools tend to be the same or very similar 90% of the time so with this in mind AEL have provided all the cost prices and technical information required for each application from 30KW up to 1000KW as a standard design so that they can be viewed and purchased online.

AEL Plate Heat Exchangers have been used to heat and cool many types of fluids in the UK for over 35 years and they all operate the same way in principle whether assembled as a Plate and Gasket unit, Brazed or supplied as a Shell and Tube unit.

In practice all three types of heat exchanger transfers energy from a hot or cold fluid and ensures that they do not mix by creating two completely independent separate heating or cooling circuits.

A standard FARAL Aluminium radiator can operate at up to 110 oC making it an ideal choice as a heat dump for a solar heating system as it will heat up and cool down very quickly because of the aluminium construction of the radiator.

A properly sized “Heat Dump” in a solar powered water heating system will avoid any damage to the solar panels caused through persistent overheating.

When using a FARAL Aluminium radiator as a heat dump it is normal practice to divert the hot water via a three port valve from the solar panel to the radiator when the cylinder has reached its optimum design temperature.

A “Heat Dump” can be positioned anywhere in or out ( using a diverting valve) of the heating system but please make sure that the KW heat you are trying to remove from the system is not excessive for the area or room it is being positioned as this might make that room very uncomfortable to live in.

It is recommended that any radiator being used as a “Heat Dump” has a full flow of water flowing across it using a lock shield radiator valve on both the flow and return of the radiator rather than a thermostatic valve on the flow that opens and closes according to the room temperature.

Using lock shield radiator valves on the “Heat Dump” or FARAL Aluminium radiator flow and return will stop anybody from adjusting the valve setting from fully open and allow the Solar Powered Central Heating water to circulate unrestricted through the radiator dissipating all the heat required from the solar heating system thus avoiding overheating and damage to the panels and associated controls.

The post WHAT IS A SOLAR HEATING SYSTEM “HEAT DUMP” appeared first on AEL Heat Exchangers.

A heat sink will stop a boiler or Primary heating source such as a boiler from thermally shutting down and can be positioned anywhere in the Central Heating circuit.

It is important that any Appliance or Secondary Circuit being used as a heat sink is at least equal to the KW heat output you are trying to remove from the Primary heating circuit.

If central heating radiators are being used to dissipate heat they must be sized correctly as excessive heat might make that room very uncomfortable to live in.

The most common place to install a heat sink radiator in a small property is in the bathroom because a bathroom radiator can remain on all the time to dry off towels but please check that the output of the bathroom radiator has enough output to be sure it can dissipate the heat required from the PHE quickly enough.

It is recommended that any radiator being used as a heat sink has a full flow of water flowing across it using a lock shield radiator valve on both the flow and return of the radiator rather than a thermostatic valve on the flow that opens and closes according to the room temperature.

Using a lock shield radiator valve on the FARAL radiator flow and return will stop anybody from adjusting the valve setting from fully open and allow the central heating water to circulate unrestricted through the radiator dissipating all the heat required from the heating system thus avoiding overheating and damage to the boiler and associated controls.

AEL supply Alfa Laval AHRI approved Plate Heat Exchangers, AHRI is a globally recognized and industry respected third party certification program that allows you the customer to differentiate between suppliers and provides the assurance and peace of mind that you are purchasing a plate heat exchanger of the highest quality.

When specifying  Engineers and other decision makers purchase an Alfa Laval Plate Heat Exchanger that bears the AHRI Certified^® mark, it will provide them with the added assurance that the equipment that they have purchased is manufactured using materials of the highest quality and that it will perform accurately and consistently in line with the design provided by AEL at quotation stage.

AEL Plate Heat Exchangers are used to either heat up or cool down many different types of fluid. When heating up a fluid such as water the Primary heat source from a boiler or waste water heat recovery system will transfer the heat energy from the Primary side to the cold Secondary side that requires heating instantaneously to a set point temperature making sure that the two circuits are kept separate.

AEL Plate heat exchangers are often used as system breaks in HVAC circuits in old systems offering protection to the boiler or fitted into new systems that prolong the life of a boiler by many years. Plate heat exchangers tend to be compact in size and fit nicely between boilers and other equipment such as pump sets and pressurization units.

The main advantages of using an AEL plate heat exchanger are:

• Compact design
• High thermal efficiency
• Easy to service.
• The duty / performance can be altered by decreasing or increasing the number of plates required.
• Suitable for Commercial and Industrial applications
• Suitable for use with water, steam and many other mediums.
• No storage and instantaneous heat up which eliminates the environment that breeds legionella bacteria.
• No standing heat losses as the water content is minimal and no storage is required.

Typical Commercial and Industrial applications where AEL plate heat exchangers have been used:

• Boiler circuit system breaks
• Swimming pool system break from Central Heating circuit.
• Renewable energy installations such as Heat pumps
• Food & Dairy process for milk pasteurising, milk cooling and general hygienic cleaning purposes.
• Heating and cooling of liquids in industrial process plants.
• Pharmaceutical Industry providing hygienic water heating and cooling
• Heating and cooling of chemicals.
• Heating, Ventilating and Air Conditioning
• Marine Environment for engine cooling, oil cooling, intercoolers and general cleaning purposes.
• Brewing process plant for cooling and conditioning fluids.
