Air compression central station needs big amount of energy to run.
This thermal energy can’t be recovered because the temperature are too low.
There is a fluid inside compressors which operate at higher temperature, it is our target in energy recovery: lubricant oil.
Oil usually operate at higher temperature (70-100°C) and need cooling to work correctly for long time.
This heat power can be easily recovered to produce hot water for heating or technical application, with TENEPAC.
TENEPAC are simply units designed to recover heat fron operating machinery.
