Compact Steam Heaters

Intertec has developed a new range of steam heaters for field instrumentation protection applications. Offering a choice of vertical, horizontal or panel mounting styles, with four power outputs ranging from around 65 to 490 W, users can easily select the appropriate heater for all common enclosure-scale freeze/condensation protection or temperature maintenance applications. The new Steam range has been developed from the most popular sizes of finned convection heater profiles in Intertec's electrical heater range. These Intertec-designed anodised aluminium profiles have all been field-proven in enclosure heating applications over many years, and in many tens of thousands of applications. Steam heating is still employed in many refineries and other plants, because steam energy is produced as a by-product of the core process, and because it is a simple alternative to electric heating. Two of the options in Intertec's new steam heater range are designed to mount vertically to provide convection heating. They are physically compact and suitable for smaller-scale heating requirements: in freeze protection applications the outputs are typically 65 and 130 W respectively when used on typical lines offering steam at a pressure of three bar and a temperature of 130°C. A third convection option is designed to mount horizontally and provides a typical output of 490 W. The fourth element has both flat and finned sides to allow it to be mounted against a panel or on the side of equipment; it delivers around 200 W of combined convection and conduction heating output, providing a useful design alternative for some process applications. The sizes of the four heaters are 5 x 5 x 15.5 cm, 8 x 8 x 22.5 cm, 22.5 x 21.3 x 10 cm, and 5 x 21.3 x 22.5 cm.
