Micro Plate Heat Exchanger Type C12L-EZ

For more ecient Cooling & Heating systems

40% heat transfer increase compared to traditional shbone 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” ow, which increases the heat transfer coecient 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

eciency, the C12L-EZ is designed to work eciently and increase comfort in modern

buildings without increasing the carbon footprint. Helping A/C units perform more eciently, it reduces both energy costs and environmental impact. The low hold-up volume reduces the system refrigerant charge and oers valuable savings.

Features:

• Improved heat transfer - equals higher eciency 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
