The Caloritech™ KX Finned Tubular Heater (Calrod® type*) is typically manufactured to custom specifications based on the customer application, where steel fins are spirally wound over a heating element and then metallurgically bonded by furnace brazing, leaving negligable thermal resistance at the joint.
They are normally used for forced convection heating applications with outlet air temperatures up to 300°C (572°F), such as forced circulation, air or gas heating systems like ducts, fan forced electric heaters, recirculating ovens and loading resistors. Finned tubular heaters offer distinct advantages over open coil heaters, including minimized risk of fire or electrical shock, longer service life and less overall required maintenance.
