The Asymmetrical Applications

We neither offer equipment to cool or heat a liquid with an un-limited air quantity nor low or medium efficiency equipment.
However, in applications with a fixed air or gas flow, where high efficiencies for the air or gas flow are paramount Airec is superior to all other solutions.

In applications such as these choose the best – choose Airec!

Liquid-to-Liquid

For asymmetrical liquid-to-liquid applications, Airec offers significant advantages. When heating water with steam the water flow is normally more than 10 times that of the steam.

Also for Water-to-Water applications where one flow is less than half that of the other, Airec offers higher efficiencies and a more compact design when compared to traditional plate heat exchangers for symmetrical applications.
