The H62L-EZU is an evaporator optimized for R410A for use in high-efficiency heat pumps with capacities of 5-20 kW.
The Z-pattern channel plate technology pushes the per formance 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 dimple plate pattern of the previous generation of MPHE, H62L-EZU reduces the water side pressure drop and the amount of material used. In the reversible mode of the heat
pump as a condenser, H62L-EZU also has outstanding performance.
To meet demands for higher seasonal efficiency, the H62L-EZU is designed to work efficiently and increase comfort in modern residential and
commercial buildings without increasing the carbon footprint. Helping heat pumps perform more efficiently, it reduces both energy costs
and environmental impact. The low hold-up volume reduces the system refrigerant charge and offers valuable savings.
