Evaporators
Transfer heat from water or glycol to the refrigerant.
REFRIGERATION & HEAT PUMPS
Compact heat transfer inside chillers and heat-pump systems.
Plate heat exchangers serve as evaporators, condensers, economizers and heat-recovery units, transferring heat between refrigerant and water or glycol in a compact package.
Duty-based selectionFluid & materialService access
01 · WHERE IT WORKS
Where the industry uses plate heat exchangers
Condensers
Reject refrigerant heat to a water circuit with controlled pressure drop.
Economizers
Support intermediate cooling or vapor-injection arrangements.
Heat recovery
Reuse condenser heat for hot water, process water or space heating.
02 · EQUIPMENT DIRECTION
How CHENHE equipment helps
Copper-brazed unit
Compact equipment integration after refrigerant and oil compatibility are confirmed.
Nickel-brazed / all-stainless
An alternative where copper compatibility or fluid chemistry requires it.
Single / dual circuit
Match compressor staging, redundancy and part-load control.
03 · SELECTION NOTES
