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 fish 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 fishbone design at the same evaporating temperature. At the same time, inheriting from the dimple features, C12L-EZ reduces
the 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.
- 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
