Danfoss BPHE / Micro Plate Series

Danfoss brazed plate heat exchangers (BPHE) deliver gasket-free, compact heat transfer for evaporator, condenser, desuperheater, and heat recovery duties. Two plate technologies are offered: the patented Micro Plate™ (MPHE) dimple design, and the legacy Fishbone (chevron) design suited to higher temperatures/pressures and more viscous fluids.

The Micro Plate™ dimple pattern creates a nozzle-diffusor channel with stronger turbulence, thinner boundary layers, and less scaling than traditional fishbone channels. The result is significantly improved heat transfer, lower pressure drop on the water side, reduced raw material use, and minimal hold-up volume — meaning smaller refrigerant charge. MPHE units cover chillers, heat pumps, and close-control systems for cooling capacities up to 800 kW / 225 TR.

Types available: the Micro Plate™ MPHE range including the C118, D118 and H118 families, plus the H48T high-pressure type rated to 140 bar on the primary side for transcritical CO₂ heat recovery, and the legacy Fishbone plate range. Copper, CoResist™ and stainless steel brazing options. Send the duty in kW or TR, the refrigerant, the water flow and the approach temperature, and we will size it.

Specify a BPHE when you need chiller, heat-pump, desuperheater or heat-recovery duty in a fraction of the footprint of a shell-and-tube — or when refrigerant charge has to come down, since the hold-up volume is a fraction of the alternative.
