The C17L-EZ is an evaporator optimized for small chillers with compact size required in installation. It’s also designed for extension to economizer and condenser for various refrigerants. The Z-pattern channel plate technology pushes the performance of heat exchangers to the limits by fully mixing the liquid and gas refrigerant through a “zigzag” flow, which increases the heat transfer coefficient. At the same time, inheriting from the dimple plate pattern of the previous generation of MPHE, C17L-EZ reduces the water side pressure drop and the amount of material used. The correspondent condenser model, H17L-CZ has outstanding performance working as condenser in semi plug-in systems and also as suction gas to liquid heat exchanger in heat pump operating with large glide refrigerants. To meet demands for higher seasonal efficiency, the C17L-EZ and H17L-CZ are designed to work efficiently and increase comfort in modern life without increasing the carbon footprint.
