The C117L-EZD is an evaporator optimized for R410A for use in high-efficiency chillers with capacities of 70-250 kW, and standard efficiency
chillers with capacities of 70-300 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 the dimple plate pattern of
the previous generation of MPHE, C117L-EZD reduces the water side pressure drop and the amount of material used. In the reversible mode of
the chiller as a condenser, C117L-EZD also has outstanding performance.
To meet demands for higher seasonal efficiency, the C117L-EZD is designed to work efficiently and increase comfort in modern commercial
buildings without increasing the carbon footprint. Helping chillers 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.
- Improved heat transfer - equals higher efficiency chillers
- Reduced water side pressure drop - equals higher efficiency chillers
- Minimal hold-up volume - equals less refrigerant charge
- Smaller footprint - enables more compact chillers
- High heat transfer and minimal refrigerant charge - equals a reduced CO2 footprint
