Welcome to Anping County Boli Hardware Wiremesh Products Factory, a trusted manufacturer since 1998 with an annual export value of US$5-10 million. Our Stainless Steel Serpentine Evaporator Coil for Food Processing Cold Room is engineered to deliver superior heat transfer efficiency and long-term reliability in demanding cold storage environments. Crafted from premium 304 stainless steel with a 5/8 inch diameter and rated for 180 PSI, this coil is designed to maintain optimal temperature control while resisting corrosion and food-grade sanitation requirements. Discover how our precision manufacturing and decades of experience can enhance your cold room performance.
Product Overview
The serpentine design maximizes surface area for efficient heat exchange, making it ideal for food processing cold rooms where consistent cooling is critical. Our coils are manufactured using advanced bending and welding techniques to ensure leak-free operation and uniform refrigerant flow. Available in customizable configurations to fit your specific cold room layout, they are compatible with a wide range of refrigerants and expansion systems.
Key Features
- Material: 304 stainless steel – excellent corrosion resistance, hygienic, and easy to clean.
- Diameter: 5/8 inch (15.875 mm) – standard size for efficient refrigerant flow.
- Pressure Rating: 180 PSI – suitable for medium-pressure refrigeration systems.
- Design: Serpentine configuration – maximizes heat transfer surface area while minimizing refrigerant charge.
- Welding: Automatic TIG welding for smooth, durable joints without leaks.
- Surface Finish: Optional polished or brushed finish to meet food industry standards.
- Customization: Available in various lengths, number of passes, and end connections (e.g., flare, solder, or threaded).
- Compatibility: Works with R404A, R134a, R22, and other common refrigerants.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for this evaporator coil?
A: Lead time depends on order quantity and customization. Standard samples can be shipped within 7-15 days, while bulk orders typically take 20-30 days. We offer expedited options upon request. -
Q: Can this coil be used with ammonia (R717) refrigerant?
A: Yes, 304 stainless steel is compatible with ammonia. However, we recommend specific surface treatment to prevent stress corrosion cracking. Please consult our technical team for guidance. -
Q: Do you offer custom sizes or number of passes?
A: Absolutely. We can customize the coil length, number of serpentine passes, and end connections to fit your cold room dimensions. Provide your drawing or spec sheet for a precise quote. -
Q: What is the cleaning method recommended for this coil?
A: Regular cleaning with mild detergent and warm water is sufficient. For food processing environments, we recommend periodic CIP (clean-in-place) using approved sanitizers. Avoid abrasive tools that could damage the surface. -
Q: How do you ensure weld quality and leak prevention?
A: All welds are performed by certified technicians using automatic TIG welding. Each coil undergoes 100% pressure testing at 1.5 times the working pressure (270 PSI) to guarantee no leaks. -
Q: Is this product suitable for outdoor cold rooms?
A: Yes, the 304 stainless steel provides excellent weather resistance. However, if the environment is highly corrosive (e.g., coastal), we may suggest 316L stainless steel as an alternative. -
Q: What packing and shipping methods are available?
A: Coils are individually wrapped in protective foam and packed in sturdy wooden crates to prevent damage during transit. We ship via sea, air, or express courier based on your urgency. -
Q: Can I get a sample before placing a bulk order?
A: Yes, we provide sample coils at reasonable cost. The sample cost will be deducted from your first bulk order. Contact our sales team for details.
