DX Evaporator Coil for 9kW ASHP(Air Source Heat Pump) Project

Direct‑expansion (DX) evaporator coil acts as the core heat‑absorbing component for air‑source heat pumps. For 9 kW residential & light‑commercial ASHP units, coil structure directly impacts heating capacity at low ambient temperature, anti‑frost performance, defrost cycle efficiency and overall system COP. Our custom DX tube‑fin evaporator coils are purpose‑built for 9 kW air‑source heat pump projects, for both new unit development and aftermarket replacement.

Manufactured with inner‑grooved seamless copper tubes and louvered aluminium fins, these DX evaporator coils are optimized for ASHP refrigeration cycle. Fin pitch, tube circuiting and coil geometry are fine‑tuned for heat pump operating conditions including winter low‑temperature operation and periodic defrosting. Every coil goes through pressure holding and leak detection before delivery.

Key Product Features

9 kW ASHP performance‑oriented design: Optimized circuit layout matched to 9 kW heating capacity; suitable for R32, R410A refrigerants. Stable heat absorption under low‑ambient‑temperature working conditions.

Anti‑frost optimized fin configuration: Reasonable fin pitch to reduce frost accumulation, improve defrost efficiency, avoid ice blockage during long‑time winter operation.

Full custom capability: OEM production according to customer drawings or physical samples. Adjust coil dimensions, row number, tube circuit, suction & liquid port size and position to fit unit cabinet layout.

Multiple surface treatment options: Standard louvered aluminium fins; epoxy anti‑corrosion coating optional for coastal, high‑salt‑fog outdoor installation environments.

Strict refrigerant‑grade testing: High‑pressure air tightness test, optional helium leak test, to eliminate refrigerant leakage risk for long‑term outdoor service.

Flexible mechanical structure: Compatible with vertical‑type, V‑type and flat‑mount ASHP cabinet assembly forms.
