Viper Coil Heaters

When highly focused heat is required, and a very low profile is imperative, coil heaters are the best cost-effective option. Coil heaters may be used to concentrate the heat on specific segments, or the coil may be spread to equalize the temperature across the object to be heated.

Backer Marathon stocks a wide variety of coil heaters, OEM replacement heaters, and will provide custom configurations upon request.
