Welcome to Anping County Boli Hardware Wiremesh Products Factory – a trusted manufacturer since 1998. Our Stainless Steel 316L Spiral Evaporator Coil is engineered for high-performance HVAC applications, offering superior corrosion resistance and thermal efficiency. With a 12mm tube diameter and 0.4mm fin thickness, this coil delivers reliable heat exchange in demanding environments. Backed by our annual export value of US$5–10 million and a global customer base across North America, Europe, Asia, and more, we ensure every product meets rigorous quality standards.
This spiral evaporator coil is designed to maximize surface area while minimizing pressure drop, making it ideal for chillers, air handlers, and refrigeration systems. The 316L stainless steel construction provides excellent resistance to chlorides, acids, and high temperatures, extending service life in harsh conditions. Whether you need a standard design or a custom configuration, our factory can tailor the coil to your specific requirements.
Key Features & Technical Specifications

Advantages & Customer Benefits
- Enhanced Durability: 316L stainless steel resists pitting, crevice corrosion, and stress corrosion cracking – ideal for ammonia, seawater, or aggressive refrigerants.
- Higher Efficiency: The spiral geometry promotes turbulent flow, improving heat transfer coefficient by 15–20% compared to standard coils.
- Space Saving: Compact design reduces footprint, allowing installation in tight HVAC enclosures.
- Low Maintenance: Smooth surfaces prevent fouling and bacterial growth, reducing cleaning frequency.
- Cost-Effective: Longer lifespan means lower replacement costs; our factory-direct pricing eliminates middlemen.
- Global Compatibility: Standard dimensions fit most OEM and aftermarket HVAC systems; custom ends available for specific connections.
Our coils are manufactured using advanced CNC bending and welding processes, ensuring consistent quality and tight tolerances. Each coil undergoes pressure testing and visual inspection before shipment. We also offer optional surface treatments such as passivation or electropolishing for enhanced corrosion resistance.

Frequently Asked Questions
Q1: What is the difference between 316L and 304 stainless steel for evaporator coils?
A: 316L contains molybdenum, which provides superior resistance to chlorides, acids, and high-temperature corrosion. It is recommended for coastal environments, chemical plants, or systems using ammonia or brine. 304 is more economical but less durable in harsh conditions.
Q2: Can this coil be used for both evaporator and condenser applications?
A: Yes, the spiral design works effectively for both evaporating and condensing processes. However, the exact configuration (fin spacing, tube length) may need adjustment based on the specific refrigerant and operating conditions. Our team can advise on the optimal design.
Q3: What is the maximum coil length you can produce?
A: We can manufacture coils up to 6 meters in a single piece. For longer requirements, we can supply multiple coils with connection fittings. Custom lengths are available upon request.
Q4: Do you provide certificates of material compliance?
A: Yes, we can provide Mill Test Certificates (MTC) for the 316L stainless steel material, confirming chemical composition and mechanical properties. Additional third-party inspection can be arranged.
Q5: How do you ensure the coil is leak-free?
A: Each coil undergoes a hydrostatic pressure test at 1.5 times the working pressure, followed by a dry air or nitrogen test. Welds are inspected visually and, if required, by dye penetrant or radiography.
Q6: What is the typical lead time for an order?
A: For standard sizes, lead time is 15–20 working days. Custom orders may require 25–35 days, depending on complexity. We can accommodate urgent requests with expedited production.
Q7: Can I request a sample before bulk order?
A: Absolutely. We offer sample coils (usually 1–2 pieces) at production cost plus shipping. Sample orders help validate fit and performance in your system.
Q8: What payment terms do you accept?
A: We accept T/T, L/C, and other common terms. For first-time customers, a 30% deposit with 70% balance before shipment is typical. Long-term relationships may qualify for more flexible terms.
