- Product Introduction
Wide Temperature Range
Our Spiral Fin Tube Heat Exchanger wraps metal fins around a steel tube. This greatly increases the outside heat transfer area. The design pressure is 0.6 to 4.0 MPa. Design temperature ranges from -20°C to 450°C. This is higher than many of our other products. Because the spiral fin tube allows hot gas to flow directly over it. Our factory is in Wuxi Taihu New Town core industrial park. We have 10,000 m² of space near ports and highways. Customers ask: "Do you meet local environmental rules?" We say: "Yes, we do." We have ISO14001 certification. All production follows environmental requirements.

Quick Lead Time and Capacity
Customers ask: "What is the lead time for standard products?" We say: "20 days." They ask: "What about custom products?" We say: "30 days." Our factory produces 50 spiral plate heat exchangers per month. Our product has similar capacity. The most common use is in industrial boiler economizers. Boiler exhaust gas is over 200°C. Releasing it directly wastes energy. Our Spiral Fin Tube Heat Exchanger recovers that heat. It preheats boiler feed water. It also works in metallurgy blast furnace stoves and chemical high-temperature gas cooling.
Client Success Story
We have a chemical client in Pakistan. Their reactor exhaust gas was 400°C. They used to release it directly. We designed a product for them. It cooled the gas down to 150°C. The recovered heat warmed their workshop radiators. They are very happy. Customers ask: "Do you have a dedicated after-sales team?" We say: "Yes, we do." Our after-sales team makes regular follow-ups. Within the 18-month warranty period, we offer free repair for non-human quality issues. We support third-party inspection. Export packing uses fumigated wooden boxes with waterproof cloth. We believe our Spiral Fin Tube Heat Exchanger is the most economical and reliable choice for hot gas waste heat recovery.
