HESSA Engineering
Application Engineering,
We have profound experience in a wide range of heat transfer applications for liquid to liquid / evaporation & condensation / gas to liquid / gas to gas / liquid to powder, We identify which Heat Exchanger products is most suitable according to individual application requirements for industries such as HVAC, Petro-chemical, Power generation, Marine, etc.. HESSA uses specialized thermal calculation software and if required refine the design looking at client specific process conditions and applicable experience.
