Custom air to water evaporator cooling coils for chillers, heat pumps, and industrial cooling systems. Copper tube aluminium fin, any dimension, manufactured in Hangzhou, China.
Air to water cooling coils — also called air-to-water evaporator coils or dry cooler coils — are heat exchangers that transfer heat from air into a water or refrigerant circuit. They are the core component of air-to-water chillers, heat pumps, dry coolers, and fluid coolers used across commercial and industrial applications.
RefriCore manufactures custom air to water cooling coils built to your exact system requirements. Whether you need a direct expansion (DX) evaporator coil for a chiller, a glycol cooler coil for an industrial process, or a heat pump evaporator for an air source system — we engineer the coil to match your duty, refrigerant, and cabinet dimensions.
All coils are fabricated at our Hangzhou factory, pressure tested with nitrogen, and shipped worldwide with full documentation.
Direct expansion evaporator coils for air-cooled and water-cooled chillers. Engineered for the refrigerant circuit, face velocity, and capacity of your chiller unit. Compatible with R410A, R32, R134a, R22, and CO₂.
Air source heat pump evaporator coils designed for outdoor units operating in ambient air. Wide fin pitch options for low-temperature performance and frost resistance. Hydrophilic or golden fin coating available.
Glycol or water circuit coils for dry coolers and fluid coolers used in industrial process cooling, data centers, and laser cooling applications. High fin density for maximum heat rejection per unit area.
Condenser coils for the hot side of air-to-water heat pumps and chillers. Custom refrigerant circuits, sub-cooling circuits, and liquid receivers integrated into the coil assembly on request.
Chiller evaporator coils for central air conditioning plants serving offices, shopping malls, and hotels. Custom sizes to fit existing chiller frames.
Precision dry cooler and chiller coils for data center cooling infrastructure. High-efficiency designs for continuous 24/7 operation.
Evaporator coils for air source heat pump outdoor units. Wide fin pitch for frost resistance in cold climates.
Glycol and water circuit coils for CNC machine tools, laser cutting, injection moulding, and other process cooling applications.
Evaporator coils for food processing chillers and cold storage facilities. Stainless steel and copper fin options for hygienic environments.
Cooling coils for power electronics, transformer oil coolers, and battery thermal management systems.

Air to water cooling coils are always custom-engineered. Send us your system parameters — cooling duty, airflow, refrigerant/fluid, and cabinet dimensions — and our team will calculate the optimal coil geometry.
Typical timeline: Engineering drawing within 3 business days. Production 15–25 days. DDP shipping available to most countries.
We also supply replacement coils for existing chillers and heat pumps — send us the original coil dimensions or model number and we'll cross-reference.
1,500 m² production floor with CNC fin-pressing, automatic tube expansion, and brazing lines for consistent quality at scale.
We calculate fin pitch, row count, and refrigerant circuit to hit your target capacity — not just copy a catalogue number.
Every coil is nitrogen leak-tested before shipment. Test certificates available for project documentation.
Sea freight, air freight, and DDP terms available. Full customs documentation provided for all destinations.
Send us your system requirements and get an engineering drawing with performance data within 3 business days — no obligation.
