ChinaFin Tube Steam Heat Exchanger for Central Air Conditioning
Fin Tube Steam Heat Exchanger for Central Air Conditioning serves as an efficient air radiator for central air conditioning, ventilation, and drying systems. Fin Tube Steam Heat Exchanger for Central Air Conditioning transfers heat between steam, hot water, or thermal oil and air, ensuring stable temperature control and high thermal performance in industrial or commercial environments.
Available materials: carbon steel, stainless steel 304, copper, and aluminum.

Product Features
1.Efficient Heat Transfer:The finned tube structure provides several times more surface area than standard smooth tubes, allowing faster and more efficient heat exchange while lowering energy costs.
2.High Durability:Manufactured from seamless steel tubes with spiral fins, the unit offers excellent pressure resistance and long service life under continuous operation.
3.Flexible Medium Options:Works with steam, hot water, or thermal oil. Typical steam pressure ≤ 0.8 MPa and hot air temperature ≤ 150°C.
4.Wide Application:Commonly used in drying systems, heating chambers, HVAC units, and other air-handling equipment.

Structural Details
1.The radiator consists of multiple rows of parallel spiral fin tubes.
2.SRZ Type: made by mechanically winding 0.5×10 mm steel strip onto an 18 mm seamless steel pipe, then zinc-coated for corrosion protection.
3.SRL Type: rolled with steel pipe and aluminum strip, offering a larger heat exchange area per unit length.
Both models can be produced in carbon steel or stainless steel, with non-standard designs available upon request.tion stages.
