MPHE C129L-EZ / C129L-CZ

12% lower hold-up volume compared with best traditional fishbone plates enables significant reduction in refrigerant charge.

The C129L-EZ is a single circuit evaporator optimized for high density refrigerants such as R410A, R32, R452B and the R454B for use in high efficiency chillers with capacities of 50-300 kW. It’s available in refrigerant optimized versions to meet the best performance based on the refrigerant used. Corresponding model for condenser duties is the C129L-CZ.

The Z-pattern channel plate technology enhances 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. At the same time, inheriting from the dimple plate pattern of the previous generation of MPHE, C129L-EZ reduces the water side pressure drop and the amount of material used. In the reversible mode of the chiller as a condenser, C129L-EZ also delivers outstanding performance.

C129L-EZ is designed to deliver high seasonal efficiency and increase comfort in modern commercial buildings while reducing both energy cost and environmental impact.

The low hold-up volume reduces the system refrigerant charge and offers also valuable savings.

Features and benefits

  • High and improved heat transfer - equals higher system efficiency
  • Reduced water side pressure drop – equals higher system efficiency
  • Minimal hold-up volume - equals less refrigerant charge
  • Smaller footprint - enables more compact chillers
  • Higher efficiency, lower refrigerant charge and less raw material contribute to a reduced CO2 footprint
