Granule Maxi is supplied with a 2-metre-long power cable (without plug) for connection to an approved mains switch. The mains switch is not included in the delivery.



Granule Maxi is standard fitted with steam reduction, which serves for a more pleasant working environment for staff and lowers the ventilation requirements in the pot wash area.

EcoExchanger is an optional add-on that cleverly combines steam reduction and heat recovery in one. Improves the working environment and saves up to 33% of the energy needed for heating the wash tank.
