Contact Suppliertubular elements are the most versatile, dependable and rugged of any heat generation device. These qualities make it an ideal heat source for many applications. Anupam uses precision wound 80-20 nickel-chrome wire to deliver an even heat distribution to the element sheath. High purity, grade a magnesium oxide is used as the internal insulation to insure the best thermal transfer and insulation resistance. A variety of electrical terminations, mounting fittings and brackets, along with the wide array of bending options, allow for easy integration into any heating system.
tubular heaters can be used in almost any application. Straight tubulars can be clamped to metal surfaces or inserted in machined grooves for conductive heat transfer. Or use a formed tubular to provide consistent heat in any type of special application.
