Custom-engineered evaporator coils for air conditioning, refrigeration, cold storage, and industrial cooling. Any dimension, any material, any application — manufactured in Hangzhou, China.
RefriCore is a specialist custom evaporator coil manufacturer based in Hangzhou, China, with over 20 years of experience producing precision heat exchangers for global HVAC and refrigeration clients. We design and manufacture evaporator coils to your exact specifications — from single prototype units to high-volume OEM production runs.
Our custom evaporator coils are used in air conditioning systems, cold storage rooms, blast freezers, refrigerated transport, commercial refrigeration, data center cooling, and industrial process cooling applications worldwide. Every coil is engineered for its specific duty — optimized for operating temperature, refrigerant type, airflow, and physical constraints.
We manufacture in copper tube / aluminum fin, copper tube / copper fin, all-aluminum microchannel, and stainless steel configurations, with optional hydrophilic, epoxy, or golden fin anti-corrosion coatings. All evaporator coils are 100% pressure and leak tested before shipment.
Whether you need a direct replacement for an existing coil, a modified design, or a completely new custom evaporator coil engineered from your requirements, RefriCore delivers competitive pricing, fast turnaround, and consistent quality backed by ISO certification.
Custom DX evaporator coils for split air conditioners, VRF systems, rooftop units, and refrigeration systems. Engineered for specific refrigerant types including R410A, R32, R404A, R134a, and R22.
Custom chilled water coils for AHU and FCU applications in commercial buildings, hotels, hospitals, and data centers. Available in 2-row to 8-row configurations with copper or stainless steel headers.
Heavy-duty cold storage aluminium coils for cold rooms, walk-in coolers, blast freezers, and industrial freezing applications. Aluminium fin construction is standard for cold storage due to its lightweight, corrosion resistance, and excellent thermal performance at low temperatures. All coils are designed for low-temperature operation down to −45°C with electric or hot gas defrost compatibility.
Compact, vibration-resistant evaporator coils for bus, coach, truck, and railway air conditioning systems. Lightweight all-aluminum and copper tube designs available.
Custom evaporator coils for commercial refrigeration display cases, supermarket systems, industrial process cooling, and specialized applications requiring non-standard coil geometries.
Evaporator coils with hydrophilic aluminum fins, epoxy coating, or golden fin treatment for coastal, marine, chemical, and high-humidity environments requiring extended service life.
The industry-standard configuration offering excellent heat transfer efficiency and cost-effectiveness for most HVAC and refrigeration applications.
Superior corrosion resistance for coastal, marine, and chemically aggressive environments. Longer service life where standard aluminum fins would corrode.
Lightweight, compact microchannel and parallel flow evaporator coils for automotive AC, transport refrigeration, and applications where weight is critical.
SS304 and SS316 evaporator coils for food processing, pharmaceutical manufacturing, chemical plants, and any application requiring hygienic or chemically resistant construction.
