Engineered specifically for R134a refrigeration systems, our air-cooled condenser coils deliver optimal heat rejection, high thermal efficiency, and reliable operation in medium and high-temperature cold storage facilities. Fully customizable for OEM/ODM projects.
Why Choose Our R134a Condenser Coils for Cold Storage?
Optimized for R134a Thermal Characteristics: Designed with precise circuit distribution and inner-grooved copper tubes to match R134a's specific heat transfer coefficients, maximizing the Coefficient of Performance (COP) of the refrigeration system.
Corrosion Resistance & Durability: Built for humid cold storage and warehouse environments. High-quality aluminum fins with optional protective coatings prevent premature oxidation and chemical corrosion.
High Airflow & Low Energy Consumption: Optimized fin geometry and louver designs reduce air-side pressure drop, enabling smaller fan power while maintaining high heat rejection capacity.
100% Leak-Proof Guarantee: Every cold storage condenser coil undergoes rigorous high-pressure nitrogen testing and underwater bubble inspections to eliminate refrigerant leaks.
| Technical Parameters | Standard Specification (Fully Customizable) |
| Compatible Refrigerant | R134a, R404A, R507A, R22 (Optimized for R134a medium temp) |
| Tube Material | Inner-grooved Copper Tube (C12200, high purity) |
| Fin Material | Aluminum Foil (Hydrophilic, Gold, or Epoxy coated optional) |
| Tube Outer Diameter (OD) | 7mm, 7.94mm, 9.52mm, 12.75mm, 15.88mm |
| Fin Pitch (Spacing) | 1.8mm – 3.2mm (Adjustable for frost management) |
| Pressure Test | 3.2 MPa Nitrogen Leak Test (100% Factory Inspected) |
| Application | Cold Storage Rooms, Walk-in Freezers, Commercial Condensing Units |
| Certifications | ISO9001, CE, RoHS Compliant |
Typical Applications in Cold Chain & Refrigeration
Our specialized R134a condenser coils are widely integrated into:
Medium-Temperature Cold Storage & Walk-in Coolers
Commercial Supermarket Refrigeration Racks
Food Processing and Agricultural Cold Rooms
Modular Condensing Units and Chillers
OEM / ODM Customization for Cold Storage Projects
Working on a custom cold storage project? We offer flexible engineering support to fit your exact system blueprints:
Customized dimensions, coil shapes, casing materials (galvanized steel or stainless steel), and connection headers.
Specialized circuit design to match specific compressor capacities (Bitzer, Danfoss, Copeland, etc.).
Low Minimum Order Quantity (MOQ) for custom prototypes.

Our Advantages
- We have customized products for many customers, following are some projects we did before.
- We can provide designing data and production drawings.
- We promise we use the design software sold by a well-known European HAVC software company. Through 8 years of cooperation with them, we have designed, processed and exported dry coolers to various countries all around the world.
- All of customers feedback is that the actual cooling performance is almost the same as the theoretical design value.
Packaging & Shipping
The normal package is wooden box. If export to european countries, the wooden box will be fumigated. If container is too tighter, we will use pe film for packing or pack it according to customers special request.
