Anupam's Micro Tubular Heaters are manufactured in round, square or rectangular section to guarantee the greatest thermal exchange keeping an excellent efficiency and a good reliability. These heaters can be manufactured with built in thermocouple J or K type. Construction : The resistive wire is uniformly distributed in a compacted MgO insulation, with a CrNi-steel outer protection sheath. The heaters are annealed after manufacturing, thus acquiring a high malleability that allows their being subsequently bent into any complex shape, with extremely narrow bending radius
