As a leading manufacturer with over 25 years of experience in metal fabrication, Anping County Boli Hardware Wiremesh Products Factory proudly presents our Industrial Closed-Loop Water Cooling Coil with Copper Tubes, 3/8" OD, 0.035" Wall, 150 PSI Working Pressure. This cooling coil is engineered to deliver efficient heat dissipation in demanding industrial environments, ensuring reliable operation of machinery and systems. Our commitment to precision manufacturing and strict quality control makes this coil a trusted component for OEMs, system integrators, and maintenance professionals worldwide.
The coil is constructed from high-purity copper tubes, offering excellent thermal conductivity and corrosion resistance. With a 3/8-inch outer diameter and 0.035-inch wall thickness, it balances strength and heat transfer efficiency. Rated for 150 PSI working pressure, it suits a wide range of closed-loop cooling applications, including hydraulic power units, air compressors, welding machines, and process cooling systems. Each unit is designed to minimize pressure drop while maximizing surface area for optimal heat exchange.
Our manufacturing process ensures consistent tube wall thickness, precision bending, and leak-free connections. The coil can be supplied in various configurations—single or multi-pass, bare or finned, and with custom end fittings (NPT, BSP, flared, etc.). We also offer optional protective coatings for harsh environments. All products undergo rigorous pressure testing before shipment to guarantee 100% integrity.

Frequently Asked Questions (FAQ)
Q1: What is the maximum temperature this cooling coil can handle?
A: The copper tubes can withstand continuous operating temperatures up to 200°C (392°F) in non-oxidizing environments. For higher temperature applications, please consult our engineering team for alternative materials or coatings.
Q2: Can the coil be made with different tube diameters or wall thicknesses?
A: Yes, we offer custom sizes. Common options include 1/4", 1/2", 5/8", and 3/4" OD with various wall thicknesses. Please provide your requirements for a tailored solution.
Q3: Is the coil suitable for use with glycol mixtures or other coolants?
A: Copper is compatible with most water-glycol mixtures, but we recommend checking compatibility with specific additives. For aggressive chemicals, an optional protective coating (e.g., epoxy or nickel plating) can be applied.
Q4: How do I determine the correct coil size for my system?
A: The required cooling capacity depends on your heat load, flow rate, and inlet/outlet temperatures. Our sales team can help you calculate the necessary surface area. Alternatively, you can provide your equipment specifications and we will recommend a suitable coil configuration.
Q5: What end connections are available?
A: We offer standard NPT (female or male), BSP, flare, compression, and plain ends for soldering or brazing. Custom connections are also possible. Please specify your preference when ordering.
Q6: Do you provide samples before mass production?
A: Yes, we can produce a sample based on your drawing or specifications. Sample cost is negotiable, and it will be deducted from the final order quantity. Lead time for samples is typically 5–10 working days.
Q7: What is the minimum order quantity (MOQ)?
A: Our MOQ for standard sizes is 100 pieces. For custom designs, MOQ may vary. We are flexible and can discuss smaller quantities for trial orders.
Q8: How do you package the coils for export?
A: Each coil is individually wrapped in protective material, then packed in sturdy cartons or wooden crates, depending on size and quantity. We ensure the packaging is suitable for sea freight, air freight, or courier shipment.
