Unique refrigerant distribution
The C55-EU is mainly developed as evaporator for high eciency chillers using R407C/R404A/R134a or other low pressure refrigerants and covering cooling capacities 10 to 65 kW (3-18 Rt), but it can also be used as economizer. Equipped with Power Bulges - an innovative distri-
bution system - the evaporators enables a perfect refrigerant distribution, thereby improving heat transfer, minimizing pressure drop and being less sensitive to inlet connection and pipe size. It is based on the well proven MPHE technology, meaning minimal refrigerant charge
and less weight for both environmental and nancial savings.
