Deodorisation and heat recovery technology

The takeover of Optimum in 2018 meant that Callens was able to acquire the requisite expertise in sustainable, environmental and energy technology. Under the name Optimum by Callens the two specialists have joined forces to develop innovative steam boiler solutions where odour control and heat recovery take centre stage.

Optimum by Callens designs, installs and services systems that control odour and hydrocarbon emissions, including pollution, on the flue gas side of industrial boilers, with heat recovery at the heart of the concept.
