Micro Plate Heat Exchanger
Type C39L-EZ
A new compact and high-e€cient evaporator
The C39L-EZ is an evaporator designed for use in high-e€ciency mini chillers with capacities up to 40kW, optimized for R410A and R32 respectively.
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 coe€cient. At the same time, inheriting from the dimple plate pattern of the previous generation of MPHE, C39L-EZ reduces the water side pressure drop and the amount of material used. C39L-EZ also has outstanding performance working as condenser.
To meet demands for higher seasonal e€ciency, the C39L-EZ is designed to work e€ciently and increase comfort in modern life without increasing the carbon footprint. Helping chillers perform more e€ciently, it reduces both energy costs and environmental impact. The low hold-up volume reduces the system refrigerant charge and offers valuable savings.
