Heat recovery from high temperature gas to water

The problem

Volvo Penta, Vara, Sweden is a leading producer of large diesel engines for marine and industrial applications. All motors are tested on a total of 9 test benches. Around 400 kW heat is exhausted from each test bench. By heat recovery to water Volvo can sell the energy to the city of Vara. This requires a high leaving water temperature and a highly efficient heat exchanger.

The solution – AirCross 21-100/x2/C - Not only saves energy, but also works as an efficient silencer

During one year test period Volvo could not only measure exceptionally high performance but also 8 dB as average sound attenuation. Work to equip the other 8 test benches is in process.
