Tubular Heater

Dpstar Group is the largest manufacturer of tubular heaters in Malaysia. Our brand is Maltec-H comes with SIRIM and C.E certification.

TUBULAR HEATER are very common and widely known among the industry. Tubular heater are extensively used because it can be used in a variety of media, i.e. water, oil, air, cooking oil, chemicals and others.

The heater tube is made of Copper,Incoloy, SS304 or SS316 depending on the media to be heated by a tubular heater. Tubular heater are made based on the diameter of the tube, the desired length and the power rating.The tube diameter commonly used is of 8 mm and 11 mm. The diameter of 6mm and 16 mm are also used, although not too common.

The main parts for construction of tubular heater is the resistance heating coil which is exactly where the electrical load occurs. The most common type of metal alloy used for this purpose is a mixture of nickel-chromium, also known as Nichrome. Nichrome wire wrapped around a ceramic core, and the number of spirals per inch density varies according to the required wattage. The potential of the source of alternating current, which can be 2-phase or 3-phase, flows through a wire Nichrome is rolled up, so that the wire gets hot, which in turn, heats the heating mantle or body tubular heater itself.

Insulation is used to prevent Nichrome coil contact with the body or casing tube to prevent short circuit. Insulation that separates Nichrome coil and sheath or body is Magnesium Oxide (MgO). To ensure MgO fill the empty space between the casing and the coil, vibration or press machine is used to condense MgO in the tubular heater sheath. The sheath is part of a tubular heater which makes contact with the substance or substances to be heated.
