Data Sheet

Micro Plate Heat Exchanger
Type C22 & H22

For more ecient Chillers & Heat Pumps

20% reduction in refrigerant charge
compared with a traditional BPHE, the ideal
solution to help you meet the world`s
climate and energy aspirations.

The C22 & H22 are families of Condensers and
Evaporators optimized for high-eciency
chillers and heat pumps.

The heat exchanger features innovative Micro
Plate technology that improves heat transfer
and reduces the amount of material used.

To meet demands for higher COPs in heat
pumps, the evaporator H22(L)-E and the
condenser H22(L)-C are designed to work
eciently with close temperature approaches,
while a low pressure drop on the brine side
reduces the pump power and keeps the overall
COP high. H22 can cover a capacity range from
2 to 10kW.

H22(L)-C represent the ideal choice for the Semi
Plug-in systems, also operating with ammable
refrigerants.

The C22(L)-E and the C22(L)-C are respectively
evaporator and condenser designed to work
eciently and increase comfort in modern
buildings without increasing the carbon
footprint. Helping chillers perform more
eciently achieving higher seasonal eciency
levels, it reduces both energy costs and
environmental impact. C22 can cover a capacity
range from 3 to 20kW.

The low hold-up volume reduces the system
refrigerant charge and oers valuable savings.

Table 1: Designation

Application

The C22 & H22 are families of Condensers and Evaporators specically optimized for high-eciency chillers and
heat pumps, dedicated to comfort applications, cooling-industrial process and semi plug-in systems in food retail
industry. The evaporators are design to operate also in reversable systems in condenser mode, in co or counter
current ow conguration; as well as the condensers are optimized and fully in regard to the defrost operation
cycle.
