High-Frequency Welded Finned Tubes for Poultry and Livestock Constant-Temperature Systems

High-Frequency Welded Finned Tubes are engineered heat exchange components specifically developed for constant-temperature systems used in poultry houses, livestock barns, hatcheries, and other controlled agricultural environments. By increasing the effective heat transfer surface area, finned tubes enable rapid and uniform heat distribution while reducing energy consumption and operating costs.

Designed to withstand demanding agricultural conditions characterized by humidity, dust, ammonia exposure, and continuous operation, our finned tubes are available in both galvanized steel and stainless steel constructions to accommodate different environmental requirements and service life expectations.

Manufactured using advanced high-frequency resistance welding technology, the fins are metallurgically bonded to the base tube, ensuring exceptional heat transfer efficiency, structural integrity, and long-term reliability.

• High thermal efficiency through continuous fin-to-tube bonding.
• Uniform heat distribution for stable indoor temperatures.
• Reduced fuel consumption and lower operating expenses.
• Excellent resistance to vibration and thermal cycling.
• Suitable for hot water, steam, and low-pressure heating systems.
• Corrosion-resistant options for harsh livestock environments.
• Long service life with minimal maintenance requirements.
• Custom dimensions and fin configurations available.

Our high-frequency welded finned tubes are widely used in:

• Poultry house heating systems
• Broiler and layer farm climate control systems
• Pig house constant-temperature systems
• Dairy barn heating equipment
• Hatcheries and breeding facilities
• Greenhouse agricultural heating
• Livestock environmental control units
• Industrial low-temperature heat recovery applications

Galvanized steel finned tubes provide excellent cost-performance characteristics. The zinc coating enhances corrosion resistance and protects the tube surface against moisture commonly found in poultry and livestock facilities.

Advantages:

• Economical solution
• Good atmospheric corrosion resistance
• Reliable mechanical strength
• Suitable for standard agricultural applications

Stainless steel finned tubes are recommended for environments with elevated humidity levels and high concentrations of ammonia or other corrosive substances.

Advantages:

• Superior corrosion resistance
• Excellent durability
• Hygienic surface properties
• Extended operational lifespan
• Reduced maintenance costs

Typical stainless steel grades include:

• SUS304 / 304L
• SUS316 / 316L
• Other grades available upon request

Customized dimensions are available according to project requirements and heating system designs.
