FAQ

Frequently Asked Questions

What information do I need to provide for a custom evaporator coil quote?

Ideally: dimensions (width × height × depth), number of rows, tube OD, fin pitch, refrigerant type, working pressure, coil type (DX or chilled water), connection sizes, and quantity. If you have existing drawings or a sample coil, send photos and dimensions. Our engineering team can work with partial information and will ask follow-up questions.

What is the minimum order quantity (MOQ) for custom evaporator coils?

We are flexible on MOQ. For standard configurations we can accommodate small orders. For completely custom designs, MOQ depends on the complexity and material requirements. Contact us with your requirements and we will advise on the most cost-effective order quantity.

Can you manufacture a direct replacement for an existing evaporator coil?

Yes. Send us photos, dimensions, and any available specifications of your existing coil and we will engineer a direct replacement. We regularly manufacture replacement coils for older or discontinued HVAC and refrigeration equipment.

What refrigerants are your evaporator coils compatible with?

We manufacture coils compatible with all common refrigerants including R410A, R32, R404A, R134a, R22, R407C, R744 (CO₂), and others. The coil design, tube wall thickness, and working pressure rating are selected based on the specific refrigerant and operating conditions.

Do you provide samples before bulk orders?

Yes. For new custom designs, we recommend a sample order for dimensional and performance verification before committing to full production. Sample lead times and costs vary by design complexity.

What quality testing do you perform on evaporator coils?

All evaporator coils undergo 100% helium leak detection and hydrostatic pressure testing before shipment. Test certificates are available on request. Our factory operates under an ISO-certified quality management system.
