Overview

Stainless Steel Coil Manufacturer

RefriCore manufactures custom stainless steel heat exchanger coils for applications where standard copper or aluminum construction is unsuitable due to hygiene requirements, chemical compatibility, or extreme corrosion resistance demands.

Our stainless steel coils are used in food and beverage processing, pharmaceutical manufacturing, chemical plants, marine installations, and industrial process cooling — anywhere that requires hygienic surfaces, resistance to aggressive cleaning agents, or compatibility with corrosive process fluids.

We manufacture in SS304, SS316, and SS316L grades, with stainless steel tube in combination with stainless steel fin, aluminum fin, or bare tube configurations depending on the application. All stainless steel coils are 100% helium leak tested and pressure tested, with material test certificates (MTCs) available on request.

With over 20 years of coil manufacturing experience and ISO-certified quality management, RefriCore delivers precision stainless steel coils to exact drawings and specifications for clients in North America, Europe, the Middle East, and Asia.

Material Grades

SS304 vs SS316 — Which Grade Do You Need?

The choice between SS304 and SS316 depends on the specific chemicals, cleaning agents, and environmental conditions your coil will be exposed to. Our engineering team can advise on the appropriate grade for your application.

SS304

Grade 304 Stainless Steel

The most widely used stainless steel grade. Excellent corrosion resistance for most food processing, HVAC, and general industrial applications. Suitable for most cleaning agents including dilute acids and caustic solutions. More cost-effective than SS316.

Food Processing Dairy & Beverage General Industrial HVAC AHU Coils Cold Storage Water Treatment
SS316

Grade 316 / 316L Stainless Steel

Superior corrosion resistance compared to SS304, with added molybdenum content providing resistance to chloride attack and pitting corrosion. Required for pharmaceutical applications, seawater, chlorinated environments, and aggressive chemical exposure.

FAQ

Frequently Asked Questions

When should I specify SS316 instead of SS304?

Specify SS316 when the coil will be exposed to chlorides (including seawater, salt air, or chlorinated cleaning agents), aggressive acids, or environments where pitting corrosion is a concern. SS316 contains molybdenum which significantly improves resistance to these conditions. For most food processing and general HVAC applications without aggressive chemical exposure, SS304 is sufficient and more cost-effective.

Can you supply stainless steel coils with full material traceability for pharmaceutical applications?

Yes. We can supply full material traceability documentation including material test certificates (MTCs) with heat/lot numbers, dimensional inspection reports, pressure test certificates, and weld inspection records for pharmaceutical and other regulated industry applications. Please specify your documentation requirements when requesting a quote.

Do you offer electro-polished stainless steel coils?

Yes. Electro-polished (EP) finish is available for pharmaceutical and food-grade applications where a smooth, low-roughness surface finish is required to minimize bacterial adhesion and improve cleanability. Please specify EP finish requirement and surface roughness target (Ra value) when requesting a quote.

What is the price difference between SS304 and standard copper tube coils?

Stainless steel coils are generally more expensive than equivalent copper tube / aluminum fin coils due to higher material costs and more demanding fabrication requirements. The actual price difference depends on coil size, row count, and quantity. Contact us for a specific quotation based on your requirements.
