The C118L-EZ is an evaporator optimized for R410A for use in high-eciency chillers with capacities of 70-250 kW.
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” ow, which increases the heat transfer coecient. At the same time, inheriting from the dimple features, C118L-EZ
reduces the water side pressure drop and the amount of material used. In the reversible mode of the chiller as a condenser, C118L-EZ also has
outstanding performance.
To meet demands for higher seasonal eciency, the C118L-EZ is designed to work eciently and increase comfort in modern buildings without increasing the carbon footprint. Helping chillers perform more eciently, it reduces both energy costs and environmental impact. The
low hold-up volume reduces the system refrigerant charge and oers valuable savings.
- Improved heat transfer - equals higher eciency chillers
- Reduced water side pressure drop - equals higher eciency 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
