HITCO’S Tubular heater are the most versatile and widely used sources of electric heat for industrial, commercial and scientific applications. Important and useful characteristics of tubular heaters are that they can be formed into virtually any shape, brazed or welded to any metal surface, and cast into metals. Carefully recharged manufacturing methods precisely selected materials, kept HITCO’S tubular heaters stand apart from other heating elements.

Specially designed helical coil of 80% nickel 20% chromium alloy resistance wire is fusion welded to nickel coated steel terminal cold pin. This coil assembly is precisely stretched and centered in the element metal sheath, which then filled with Grade “A” magnesium oxide powder (MGO). The filled tube is then compacted by a roll reduction mill into solid mass, permanently stabilizing the coil in the center of the tube while providing excellent heat transfer and dielectric strength between the coil and the sheath.
