Micro Plate Heat Exchanger
Type C22 & H22
For more ecient 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-eciency
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
eciently 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
eciently and increase comfort in modern
buildings without increasing the carbon
footprint. Helping chillers perform more
eciently achieving higher seasonal eciency
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 oers valuable savings.
