ProductsHeat pump system

Energy efficient, cost effective boiler-less washers

A heat source must provide hot water for the wash and rinse cycles, as well as hot air for the drying process. Steam boilers are used as the heat source in over 90% of conventional container and palette washers.

Now it is possible to use a hybrid boiler/centrifugal spin dry/heat pump arrangement, or even a boiler-less system. In doing so, considerable cuts can be made to both running costs and CO2 emissions.。
