Air to air heat exchanger

In many industrial processes hot exhaust air or gas is still today blown out to the environment without using its thermal energy. But in the context of higher energy costs and limits concerning CO2 emissions companies are required to make processes more efficient. First step is always to realize an internal waste heat recovery system - in this case meaning preheating fresh air by the exhaust air. The Kelvion AirToAir heat exchangers are the first choice for this purpose. That's how it works: Warm air from the process flows around thinwalled plain tubes, cools down and condenses if necessary. Cold fresh air flows inside the tubes, is preheated by the exhaust air und then brought into the process - realizing an efficient heat recovery. Air to Air heat exchangers are designed as both simple crossflow and cross-counterflow with reversal hoods. As material stainless steel is used, thus the condensation of water is not crititcal.
