Microchannel Heat Exchanger for Heat Pump Water Tank

CSTHEATEXCHANGER, a professional manufacturer of aluminum microchannel heat exchangers, expands its product portfolio with tailor‑made microchannel heat exchangers dedicated for heat pump water tank systems, supporting OEM & ODM orders for global residential and commercial domestic‑hot‑water (DHW) equipment manufacturers.

Against the global trend toward low‑GWP refrigerants and higher energy‑efficiency standards for heat pump water heaters, conventional fin‑and‑tube coils face obvious limitations: bulky size, heavy weight, higher refrigerant filling volume and insufficient heat‑transfer performance under partial‑load working conditions. Microchannel heat exchanger technology brings practical solutions for modern heat pump water tank units.

Our microchannel heat exchangers for heat pump water tanks adopt multi‑port aluminum flat‑tube and louver fin structure. Compared with traditional fin‑and‑tube heat exchangers, key advantages include:

Superior heat transfer performance: 20‑35 % improvement in thermal efficiency, faster tank water heating and higher COP for the whole heat‑pump system.

Low refrigerant charge: Compact internal volume greatly reduces refrigerant filling quantity, well‑suited for A2L low‑GWP refrigerants such as R290 and R454B, meeting safety charge‑limit requirements for water‑heater machines.

Lightweight & compact footprint: Up to 60 % weight reduction, saving internal cabinet space and simplifying equipment assembly.

Flexible customization: Manifold layout, circuit configuration, connection ports and outer dimensions can be produced strictly according to customer drawings or sample parts. Epoxy anti‑corrosive coating is optional for humid or coastal working environments.

Wide operating range: Stable performance for residential all‑in‑one heat‑pump water heaters and commercial large‑capacity hot‑water tank units across varied ambient temperatures.

“Many heat‑pump water‑tank OEM customers are seeking compact coils that match new low‑GWP refrigerants without sacrificing heating capacity,” said our product engineer. “Our microchannel solution helps equipment makers upgrade product energy ratings while controlling overall material costs.”

CSTHEATEXCHANGER accepts small‑batch prototype orders and mass‑volume OEM manufacturing. All heat exchangers go through pressure‑resistance and leak‑testing before delivery.
