The square finned heating tube is designed for efficient air and gas heating applications requiring high thermal output and compact installation.
The square fin structure provides a larger heat dissipation surface compared to traditional round-finned elements, allowing faster heat transfer, higher efficiency, and uniform temperature distribution.
The heating tube is constructed with a high-quality stainless steel, copper, or nickel–iron–chromium alloy sheath, filled with high-purity magnesium oxide insulation powder for excellent thermal conductivity and electrical insulation.
The square fins are mechanically bonded to the sheath, ensuring maximum heat exchange and long-term durability even under continuous operation.
This design is widely used in air heaters, drying ovens, dehumidifiers, and industrial heating systems that require stable, efficient heat performance.
