As a trusted manufacturer based in Hengshui, Hebei, China, Anping County Boli Hardware Wiremesh Products Factory has been delivering high-quality industrial components since 1998. Our Circular Stainless Steel Evaporator Coil is engineered to meet the rigorous demands of modern HVAC and refrigeration systems. With a thickness of 1.2mm and premium 304 stainless steel construction, this coil offers exceptional corrosion resistance, durability, and thermal efficiency. Combined with a fin density of 10 fins per inch, it ensures optimal heat transfer performance while maintaining low air resistance, making it an ideal choice for evaporators in chillers, air handling units, and process cooling applications.
Our manufacturing process adheres to ISO compliant standards, ensuring consistent quality and dimensional accuracy. Each coil is produced with precision-wound fins and seamless tube joints, guaranteeing leak-free operation under high pressure. The circular design allows for compact installation and uniform airflow distribution, enhancing overall system efficiency. Whether you need a standard size or a custom configuration, we offer flexible design options to match your specific requirements.
Key Features & Technical Specifications
- Material: 304 stainless steel (both fins and tubes) – excellent resistance to corrosion, oxidation, and chemical attack.
- Thickness: 1.2mm wall thickness for robust structural integrity and prolonged service life.
- Fin Density: 10 fins per inch (10 FPI) – balances high heat transfer coefficient with manageable pressure drop.
- Shape: Circular coil geometry – facilitates even air distribution and simplifies duct or housing integration.
- Connection Options: Available with threaded, flanged, or welded ends (customizable).
- Operating Pressure: Designed to withstand typical refrigerant pressures up to 30 bar (optional higher ratings available upon request).
- Temperature Range: Suitable for use from -20°C to +150°C, depending on application.

Our circular evaporator coils are manufactured using state-of-the-art CNC bending and automated fin pressing equipment, ensuring tight tolerances and consistent fin pitch. Each coil undergoes a 100% pressure test with nitrogen or dry air to verify leak integrity. The 304 stainless steel composition eliminates the risk of galvanic corrosion when used with compatible refrigerant circuits, and the smooth internal tube surface minimizes refrigerant pressure drop, contributing to higher system COP.
Benefits for Your Application
- Enhanced Heat Transfer: 10 fins per inch provide a high surface area for efficient heat exchange, reducing the required coil size or improving system capacity.
- Long Service Life: 304 stainless steel resists rust, pitting, and stress corrosion cracking, even in humid or chemical environments.
- Easy Maintenance: The smooth fin surface reduces dirt accumulation, and the circular shape allows easy cleaning with compressed air or water.
- Space-Saving Design: Compact circular geometry fits into tight equipment enclosures or cylindrical housings.
- Customizable: We can adjust coil diameter, circuit count, connection type, and fin pattern to match your exact specifications.
- Reliable Performance: ISO compliant quality control ensures every coil meets strict performance and safety standards.

Frequently Asked Questions (FAQ)
-
Q: What is the material of this evaporator coil?
A: The coil is made entirely from 304 stainless steel, including tubes and fins. This ensures excellent corrosion resistance and durability in harsh environments. -
Q: Can the coil thickness be customized?
A: Yes, while the standard thickness is 1.2mm, we can produce coils with other wall thicknesses (e.g., 1.0mm, 1.5mm) upon request. Please contact our sales team for options. -
Q: What does 10 fins per inch mean for performance?
A: A fin density of 10 FPI provides a moderate surface area for heat transfer, balancing efficiency with air resistance. It is suitable for most commercial refrigeration and HVAC applications. Higher or lower FPI options are available. -
Q: Is the coil ISO certified?
A: Our manufacturing process is ISO compliant, meaning we follow internationally recognized quality management principles. However, we do not hold a specific ISO certificate for the product – we can provide a letter of compliance if needed. -
Q: What is the typical lead time?
A: For standard sizes, lead time is approximately 15-20 working days. Custom orders may require 25-30 working days, depending on complexity. We recommend inquiring early for large quantities. -
Q: How is the coil packaged for export?
A: Each coil is individually wrapped with plastic film, then packed in a reinforced wooden crate or carton to prevent damage during transit. We also offer custom packaging upon request. -
Q: What refrigerants can this coil be used with?
A: It is compatible with most common refrigerants such as R134a, R404A, R410A, R32, and R290. For specific compatibility, please consult our technical team. -
Q: Do you provide samples?
A: Yes, samples are available. We can produce a small batch for testing and evaluation. Sample cost and shipping are negotiable. Please contact us for details.
