Heat recovery with the help of heat exchangers In industry, waste heat occurs at many points in the production process, which is often released into the environment without being used. In many cases, energy is even used to cool the waste heat flows from production so that they can be released into the environment. Heat exchangers (also called heat exchangers) are used for heat recovery so that the waste heat generated in the production process can be used again in the company. Gaseous or liquid media Waste heat can be in the form of gaseous media (e.g. warm exhaust air, steam, exhaust gases, etc.) or in the form of liquid media (e.g. hot water or other liquids). With the help of heat exchangers, the waste heat can be recovered from both gaseous and liquid media and then made available to the production process at a suitable point as energy in gaseous or liquid media. This process is known as energy recovery or also as heat recovery.

The heat recovery ventilation unit HRU-PremAIR has an air flow capacity of 350 m3/h at 100 PA. Designed to use aluminum heat exchangers and EPP self-supporting casing. Heat exchangers that are used depend on the model, such as counterflow aluminium heat exchanger (HRV) or counterflow enthalpy exchanger (ERV).

Heat recovery ventilation unit HRUPremAIR is a modern device with 350 / 450 or 500 m3/h air flow @ 100 Pa. Unit is made from cutting edge materials aluminim heat exchanger and EPP selfsupporting casing. Depending on the model, following heat exchangers are used counterflow aluminium heat exchanger (HRV) or counterflow enthalpy exchanger (ERV). Enthalpy exchangers in HRUPremAIRE series have a polymer membrane that effectively recovers heat and moisture from the extract air. Such membrane works like a membrane in waterproof trekking clothing i.e. it allows water vapour to pass through, but not liquid water and air. The enthalpy exchanger also blocks the transfer of odours, bacteria and spores. The exchanger material, is needless to say, primarily optimized for maximum heat recovery efficiency. PremAIR air handling units optionally can be equipped with the Constant Flow system, whose task is to maintain a constant air flow in the installation.

The FLX-PLO-EPP-F plenum boxes are part of the FLX-REKU air distribution system designed for domestic mechanical ventilation systems, so-called the MVHR system, to which an air valve and FLX-HDPE / FLX-HDPE-A ducts with a diameter of Ø75 are mounted.

With heat recovery systems in industrial environments, the heat contained in the exhaust air is efficiently used to heat air or water. A very efficient use of this energy is the preheating of dryer supply air. The heat can be used continuously here. This warm exhaust air is also suitable for heating buildings. Depending on the local conditions, both airtoair heat exchangers and airtowater heat exchangers can be used for this purpose. The heated air, in turn, is fed into production and factory halls or other areas of the building. This type of supply air heating is particularly costefficient. Such recovery systems also have a positive effect in terms of environmental compatibility. Waste heat from industry that is harmful to the climate is no longer released into the environment but remains in the cycle of the production process or building heating. The systems are also suitable for cooling rooms when outside temperatures are hot, for example.

Our heatrecovery systems heat fresh air with the thermal energy of exhaust air and can be placed directly on top of a stenter frame. This system can also be retrofitted for older dryers. The benefits are high energy savings which allow payback periods of less than two years, depending on the layout and process, highly efficient platetype heat exchangers with nonstick coating, optimum ease of maintenance by removable drawersized heat exchanger modules, external cleaning of the heatexchangers in a hot water bath with ultrasonic cleaning equipment, high power density, higher than with usual tubetype heatexchangers.

Cooling tube for fast and flexible cooling. Made out of high quality V4A stainless steel spiral tubing for efficient heat transfer. Unlike conventional corrugated pipes, the smoother shape of the (spirally-shaped) surface improves heat transfer and cleaning.

Refra buffer tanks with an integrated heat recovery are an innovative and highly cost-effective systems that are rapidly gaining popularity in commercial sector. A special buffer tank with a built-in double wall heat exchangers acts as an intermediary to collect and utilize excess heat. This system is characterized by the fact that it allows the heat generated by the operation of the refrigeration equipment to be used for other heating purposes in the same building. By installing one system, the customer gets heating and cooling at once, as well as huge savings in energy and equipment costs. These tanks are available with an anti-legionella kit, which prevents the spread of bacteria and is therefore particularly important for domestic water systems. A special 6 or 9 kW electric element can be added for additional water heating that will heat the water in the tank to the required temperature.

The thermal incinerator (TI for short) is a system which converts gas or vaporous pollutants found in exhaust gas into non-polluting compounds by way of direct combustion. This machine is characterized by: The thermal incinerator (TI for short) is a proven and robust plant for the conversion of organic pollutants (VOCs, etc.). Today it is used especially for processes which involve high exposure to condensation or dust, or for specialized solutions requiring greater heat recovery potential. An example of this would be exhaust gases containing plasticizers or siloxane. The modular design of the combustion chamber and heat exchanger especially is conducive to servicing and cleaning compared to other designs. The polluted air is forced by means of a centrifugal fan into the tube bundle heat exchanger where it circulates around the tube bundle in a cross-current fashion. The heat exchanger can be designed for an efficiency of up to 70%. The pollutants are converted in the combustion chamber at a temperature of around 760 °C. After extensive heat transfer to the raw noxious gas, the cooled clean gas leaves the plant, where it can be supplied to various heat recovery systems (or a combination of several). The auxiliary burners can be operated with natural gas or propane or light heating oil.

The smog filter is designed for effective filtration of the socalled particulate matter. The PM2.5 and PM10 particles are the main component of smog, which have an optical diameter of 2.5 and 10 μm (micrometers). The filtration efficiency (removal) of PM2.5 particles reaches up to 73%, and PM10 particles up to 81% (according to tests carried out with a dust particle measuring device). The smog duct filter consists of a sealed filter box and two filters prefilter and smog filter. It is recommended to install a smog filter on the supply ducts in domestic ventilation and heat recovery systems. In the MOCarzCA version prefilter I3 was replaced by an activated carbon prefilter (or activated charcoal). The main purpose of using such a material is deodorization of air and preliminary cleaning of dust and gaseous pollutants. Activated carbon has a huge adsorption surface, which effectively "binds" on its surface particles of pollutants, bacteria, hydrocarbons.

Electrostatic precipitator eMOCarz was design for residential buildings. Compact size and exceptionally low pressure drop makes it suitable for residential heat recovery systems, with little impact on system performance. The filtration efficiency of ePM1 and ePM2.5 particles, the main component of smog, is as high as 95%. Polluted air initially passes through a steel mesh prefilter (which retains larger fractions), then is positively ionized in an electric field due to the “crown discharge” effect. In the last stage, the previously charged particles, are pulled by electrostatic force toward horizontally mounted aluminium plates (electrodes) and build up on their surface. Electrostatic filters (precipitators) have low power consumption (only few Watts), long service life and most of all there’s no need to exchanged dirty (clogged) filters. It is enough to clean in with water and detergent once or twice a year. There is a led status indicator on the casing.

The insulated manifold box is used for mechanical ventilation systems with heat recovery (MVHR). MVHR manifolds do not need to be insulated onsite thanks to the insulating properties of EPP.

Exhaust air purification and heat recovery systems are generally not standard applications, even if individual assemblies are now modular. We have made it our goal to offer our customers the best solution for their task. To do this, we take a step back with our customers in order to gain an overview of the whole. Together we look at how the exhaust air is generated and try to start our concepts right at the point of origin. Only then can we decide which exhaust air system is the most economical when considering the total cost of ownership and compliance with the limit values. Should an extended consideration be necessary, we can accompany you from basic to authority to detail engineering. In addition, it is not uncommon for pilot tests to be offered, which lead to the later real scale of the systems by means of scaleup. With these consulting and engineering services, we offer you a manufacturerindependent package with which you can make the right decision for your company.

Besides primary measures, Selective Catalytic Reduction (SCR) is the most effective method for controlling nitrogen oxide emissions (NOx) from combustion sources. It is a commercially proven flue gas treatment technology that has been demonstrated to remove over 98 percent of the NOx contained in combustion system exhaust gas. The catalyst is at the heart of the SCR process. It creates a surface for reacting the NOx and ammonia, and allows for the reaction to occur within typical flue gas temperature ranges.Hamon uses a similar technology to reduce also VOC or CO content.Thorough knowledge in the design of all types of heat recovery systems including heat exchangers made of glass or fluoroplastic tubes to de-saturate the flue gas downstream a wet scrubbing system allows for minimum energy consumption when the flue gas needs to be heated.
