As a leading manufacturer with over 25 years of experience, Anping County Boli Hardware Wiremesh Products Factory proudly presents the Stainless Steel Evaporator Coil, 304L, 3/4" Tube, 8 FPI. This coil is designed to deliver exceptional heat transfer efficiency and long-term durability in demanding environments. Built from premium 304L stainless steel, it resists corrosion and oxidation, making it ideal for HVAC, refrigeration, and industrial cooling applications. With our commitment to quality, we provide technical support and a free replacement policy, ensuring your peace of mind.
Our evaporator coils are manufactured using advanced machinery and strict quality control processes. The 304L grade offers low carbon content, which minimizes carbide precipitation during welding, enhancing corrosion resistance. The 3/4-inch tube diameter optimizes refrigerant flow, while the 8 FPI (fins per inch) configuration balances heat transfer and air resistance, suitable for both low and medium temperature applications. Each coil undergoes rigorous pressure testing and leak detection before shipment.

Q: What is the warranty period and what does the free replacement cover?
A: The standard warranty covers manufacturing defects for 12 months from the date of shipment. Free replacement is provided if the coil fails due to material or workmanship issues. Damage caused by improper installation, misuse, or external factors is not covered. Please refer to our warranty policy for full details. -
Q: Can you customize the coil dimensions or circuit configuration?
A: Absolutely. We can produce coils with custom length, width, depth, number of rows, tube patterns, and header connections. Provide your drawings or specifications, and we will design accordingly. -
Q: What is the typical lead time for standard coils?
A: For standard sizes (e.g., 2-row, 3/4" tube, 8 FPI), lead time is approximately 15-20 working days after order confirmation. Custom orders may take 25-30 working days. -
Q: How is the coil packaged for export?
A: Each coil is individually wrapped with protective foam and polyethene, then placed in a sturdy wooden crate or steel-framed box to prevent damage during transit. We also offer custom packaging upon request. -
Q: Do you provide technical support for installation?
A: Yes, our engineering team can provide guidance on proper installation, brazing procedures, pressure testing, and system integration. Contact us via email or phone for assistance. -
Q: What is the maximum operating pressure for this coil?
A: Standard design is 300 psi (20 bar). For higher pressure applications, we can reinforce the coil with heavier wall tubes or additional support. Please specify your requirements. -
Q: Can I order a sample coil for testing before bulk purchase?
