Micro Plate Heat Exchanger

Type C12L-EZ

For more efficient Cooling & Heating systems

40% heat transfer increase compared to traditional fishbone design.

The C12L-EZ is an economizer optimized for R410A for use in VRF, heat pump and bus A/C etc., and also can be used as evaporator for chiller with a capacity under 5.5KW. Inspired by €sh scales, 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 by 40% compared with traditional €shbone design at the same evaporating temperature. At the same time, inheriting from the dimple features, C12L-EZ reducesthe amount of material used. To meet demands for higher seasonal efficiency, the C12L-EZ is designed to work efficiently and increase comfort in modern buildings without increasing the carbon footprint. Helping A/C units 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.

Features:

• Improved heat transfer - equals higher efficiency chillers

• Minimal hold-up volume - equals less refrigerant charge

• Smaller footprint - enables more compact size

• High heat transfer and minimal refrigerant charge - equals a reduced CO2 footprint
