Type of Immersion Heaters

An immersion heater is a device which is installed in a tank or container to heat a liquid. The installation can be over the side, flanged or threaded.

Flange Immersion Heaters

Flange Immersion Heaters ideal for generating steam and heating gases and liquids in pressure vessels or tanks. Flanged immersion heaters are hairpin shaped tubular heating elements welded or glanded into a blind pipe flange. Available in a wide selection of flange sizes and with a variety of electrical enclosures.

Screw Plug Immersion Heaters

Screw plug immersion heaters consist of tubular elements in a threaded hex plug. Screw plug immersion heaters screw directly through threaded openings in tank walls to heat liquids, fluids,air, and gases by direct contact.

Over The Side Immersion Heaters

Over The Side Immersion Heaters are widely used in the metal finishing industry in plating tanks due to their convenience at lesser cost when compared to a L-shaped Immersion Heater. The chemical solution in the plating tank doesn’t need to removed to change heaters. Over the side Immersion Heaters are typically used in smaller tanks/in larger tanks with a steering device for temperature uniformity with lower temperatures.

Standard and custom designs are available for tailored solutions to your thermal application requirements. Contact us today.


Immersion Heaters

Immersion heaters are designed  for direct immersion in liquids such as water, oils, solvents and process solutions, molten materials as well as air and gases.Immersion heaters are a fast and efficient way of heating up various liquid solutions in processing equipment, as well as in large tanks through the use of tank immersion heaters. Heating up liquids using direct heat transfer allows for the liquid medium to quickly reach the desired temperature using heating elements such as Flanged Immersion Heaters, Screw Plug Immersion Heaters, Over The Side Immersion Heaters or L-Shaped Immersion  Heaters.

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.
