Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer established in 1998 with an annual export value of US$5 Million – US$10 Million. Our 304 Stainless Steel Spiral Evaporator Coil (3/8 Inch Tube, 0.5mm Fin) is engineered to deliver superior heat transfer efficiency and long-lasting durability for industrial evaporation systems. This coil combines the corrosion resistance of 304 stainless steel with a precision spiral design, ensuring optimal performance in demanding environments. Whether you need a replacement coil for a refrigeration system or a custom evaporator unit, our product offers reliable operation and easy integration.
The spiral evaporator coil is manufactured from high-quality 304 stainless steel, providing excellent resistance to oxidation, acidic media, and high temperatures. The 3/8 inch (9.525mm) tube diameter is a standard size that fits most commercial and industrial evaporator systems, while the 0.5mm fin thickness maximizes surface area for efficient heat exchange without adding excessive weight. Each coil comes with a 1-year warranty against manufacturing defects, giving you peace of mind. Below are the key technical specifications:
| Parameter | Value |

| Material | 304 Stainless Steel |
| Tube Outer Diameter | 3/8 Inch (9.525 mm) |
| Fin Thickness | 0.5 mm |
| Coil Shape | Spiral (Helical) |
| Number of Turns | Customizable (typically 5–20) |
| Coil Diameter | Available upon request (e.g., 100–500 mm) |
| Surface Finish | Bright Annealed (standard), pickling optional |
| Warranty | 1 Year |
Key Features and Benefits:
- High Corrosion Resistance: 304 stainless steel withstands moisture, chemicals, and temperature fluctuations, making it ideal for refrigeration, air conditioning, and industrial evaporation.
- Enhanced Heat Transfer: The spiral configuration increases the effective surface area per unit volume, improving heat exchange efficiency compared to straight tube coils.
- Compact Design: The helical shape allows for a smaller footprint, saving space in equipment such as chillers, ice machines, and evaporators.
- Precision Manufacturing: Each coil is formed with consistent pitch and diameter, ensuring uniform flow and minimal pressure drop.
- Easy Installation: The 3/8 inch tube end is compatible with standard compression fittings, flare connections, or brazing, simplifying integration into existing systems.
- Customizable Options: We offer custom coil diameter, number of turns, tube length, and end connections to meet specific project requirements.
- Durable Construction: The 0.5mm fin thickness provides a balance between structural rigidity and heat transfer performance, suitable for both low and high pressure applications.
Our spiral evaporator coil is widely used in the following applications:
- Refrigeration systems (commercial refrigerators, freezers)
- Industrial evaporators and condensers
- Heat pumps and HVAC equipment
- Food processing and beverage cooling
- Chemical processing and pharmaceutical equipment
- Ice making machines and cold storage
Frequently Asked Questions (FAQ):
-
What is the maximum operating temperature and pressure for this coil?
304 stainless steel can typically handle temperatures up to 800°C (1472°F) in oxidizing environments, and pressure ratings depend on the coil geometry. For specific pressure requirements, please contact us with your design parameters. -
Can this coil be used with ammonia or other refrigerants?
Yes, 304 stainless steel is compatible with ammonia, R134a, R410A, and many other refrigerants. However, always verify compatibility with your specific refrigerant and operating conditions. -
Do you offer custom coil dimensions?
Absolutely. We can adjust the coil diameter, number of turns, tube length, and fin spacing. Please provide your required specifications for a custom quote. -
How is the coil packaged for shipping?
Each coil is individually wrapped with protective material and packed in a sturdy carton or wooden crate to prevent damage during transit. We ship from ports including Tianjin, Qingdao, and Shanghai. -
What is the lead time for standard coils?
For standard sizes, lead time is typically 7–15 working days. Custom orders may require 15–25 working days depending on complexity. -
Is the coil surface treated for extra corrosion resistance?
The standard surface finish is bright annealed, which provides good corrosion resistance. For aggressive environments, we can apply passivation or electropolishing upon request. -
Can I get a sample coil before placing a bulk order?
Yes, sample orders are welcome. We can produce a single coil for testing purposes. Sample cost and shipping will be quoted. -
What is the warranty coverage?
The 1-year warranty covers manufacturing defects in materials and workmanship. It does not cover damage caused by improper installation, misuse, or unauthorized modifications.
Backed by over 25 years of manufacturing experience and a strong export track record to markets across North America, South America, Europe, Asia, Africa, and Oceania, Anping County Boli Hardware Wiremesh Products Factory is your reliable partner for high-quality heat exchanger components.
