- Product Introduction
Compact and Leak-Proof Design
Our Finned Double Pipe Heat Exchanger is the smallest unit in our product line. Its structure is special. One small pipe sits inside a larger pipe. One fluid goes through the inner pipe. The other fluid goes through the gap between pipes. We add fins to both the inner and outer pipes. This gives much more heat transfer area than a normal double pipe unit. Our company started building factories in 1997. We registered the company in 2005. We finished shareholding restructuring in 2025. Our factory is 10,000 m² with over 40 staff. Customers ask: "Do you have a dedicated after-sales team?" We say: "Yes." Our after-sales team emails overseas clients regularly to check equipment operation.

Best for Small Flow and Pure Fluids
This product is perfect for labs and fine chemical work. It is small and efficient. The double pipe design stops cross-contamination between fluids. For example, you may need to heat an expensive medical liquid. You want zero leakage. Our finned double pipe design gives both safety and efficiency. It is also used in refrigeration systems for subcooling or superheating refrigerant. A pharmaceutical client in Pakistan uses our Finned Double Pipe Heat Exchanger to heat an injection liquid. The flow rate was only 0.5 m³/h. The temperature needed to rise from 10°C to 60°C. We designed a 2 m² unit. It solved their problem perfectly.
Sample and Custom Orders
Customers ask: "Do you offer free samples?" We say: "No." But we can make one small unit for your test. Custom sample lead time depends on size and quantity. The fastest is 30 days. All our equipment goes through pressure testing and helium leak testing before shipment. Export packing uses fumigated wooden boxes with waterproof cloth. We buy domestic insurance from factory to port of loading. We believe our Finned Double Pipe Heat Exchanger is your first choice for small flow, high purity, and contamination-free heat exchange.
