Duraline Heaters, Designed to be quickly installed and adaptable to any structure, building block structure allows the system to be expanded or broken down to accomplish large or small jobs by adding or removing components. Positive, no-fail watertight shielded connections, molded distribution blocks, and mating plugs are molded to 600 volt insulated cable. Duraline Heaters use power from 230 or 460 volt AC source and convert it directly into heat by means of electrical resistance. Heavy Duty Heaters are designed expressly for heavy industrial use and provide years of trouble-free use.
