A range of flat tubular heaters used for heating air, gas liquids, oil and for heating of railway points.
The surface area of tubular heaters is enlarged by the fitting of finns to enable the heater to effiently heat air or gases. These heaters have a short lengh but a high power.
Channel air heaters for air-conditioning and drying apparatus are also available please see enclosed pdf with further information and technical details..

T+H air heaters type HRR consist of tubular heaters or finned tubular heaters assembled into a sheet metal housing made of zinc plated steel or stainless steel. According to the requirements given by the specification the housings can be adapted to various applications as per the illustrations indicated beside. For most applications finned tubular heating ele ments are used as their increased surface area allows low surface temperatures on the heating elements thus providing a low watt density and a long lifetime with reduced housing dimensions.
By means of electrical interlock it has to be assured that the heater can only be operated when a fan has been activated. In order to prevent the air filter from overheating and to avoid a too high outlet temperature the air heaters can be equipped with a thermostat and/or a temperature limitor.
