District heating substations
Separate primary and secondary networks for independent pressure, water quality and control.
HVAC & DISTRICT ENERGY
Efficient separation and heat recovery for building energy systems.
Plate heat exchangers are used in district-energy substations, chiller rooms, domestic hot-water and heat-recovery loops to separate water circuits in a compact, controllable and serviceable system.

01 · WHERE IT WORKS
Where the industry uses plate heat exchangers
Chilled-water isolation
Protect chillers and building loops from different pressure and maintenance conditions.
Domestic hot water
Deliver rapid heat transfer for peak hot-water demand.
Heat recovery
Recover useful heat from condenser water and process-return loops.
02 · EQUIPMENT DIRECTION
