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.

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).

ASCO CO2 Gas Revert Recovery Systems are engineered to efficiently recover the revert CO2 gas from ASCO Dry Ice Pellet and Block Machines which normally direct the revert (flash) gas to the atmosphere. When dry ice is produced the conversion rate from liquid CO2 to dry ice is approx. 4045 %. This means 5560 % is lost to the atmosphere. This conversation rate is a physical fact and therefore, unfortunately, not to change. With a CO2 Revert Recovery System, however, most of the CO2 can be recovered which leads to a final conversion rate of approx. 9095 %. This way, the dry ice production costs are reduced up to 50 %.
