Industrial Heaters

We are one of the leading manufacturers, exporters and suppliers of a wide range of water treatment systems. These heaters are manufactured using premium quality raw material, which increases their efficiency and functional life. Further, to meet the diverse requirements of our clients, we also offer customized solutions to them.

 

Our wide range encompasses:


Coil Heaters

Coil Heaters

Coil Heaters hot

Micro Coil Heaters are hygroscopic in nature due to Mgo contents. if kept unused for longer period, there is moisture deposition on the terminals. therefore we recommend you to de-moisturize the heater prior to installation by heating them at 100-200 C in an oven for approximately 1 to 2 hours or use controllers with soft start function. This will help evaporate any moisture present inside.

Tubular Heaters hot

Formed Tubular Heaters can be supplied in either Stainless Steel or Incoloy.

The helical wound heating wire is made of a high temperature resistant NiCr alloy. And the insulation consists of superior grade of magnesium oxide (MgO). As the heaters are swadged, even at high sheath temperature they have excellent electrical insulation and a high heat transfer. To prevent the heater from moisture the connection ends are sealed with sealing components.

For manufacturing formed elements it is necessary to have a accurate dimensional sketch showing all the centre distances, radius and degrees, thus they need to be provided while placing the order.

Cast In Brass Coil Heaters

Cast In Brass Coil Heaters

Cast In Brass Coil Heaters

We offer quality Cast In Brass Coil Heaters to our clients across the globe, which are known for their features such as high temperature tolerance, application specific design and durability. These Cast In Brass Coil Heaters are advance concept of thermal engineering, which are similar to high watt density cartridge heaters. Also known as high performance tubular heaters or cable heaters, the construction of these heaters consist of compacted MgO, high temperature resistance wire and stainless steel tube. Moreover, we can manufacture these heaters with or without built in thermocouples. Generally installed in the place where space available for heating is limited and are widely used on hot runner nozzles, and manifolds, die cast nozzles and packaging machines.

Micro Tubular Coil Heaters

We are offering to our clients, Micro Tubular Coil Heaters, which are swaged and compacted to their diameters and fitted into special clamps to tighten over circular parts for heating purpose. These are manufactured as per the industry standards and are provided to our clients in customized specifications.

Nozzle Heaters  new

We offer a range of high performance nozzle heaters that are reckoned for its robust design and efficiency. The coil heater is mounted over the brass collet, which is designed and machined to high accuracy for proper transfer of heat and are covered with a stainless steel clamping band. When the clamping band is tightened, the brass collet firms its grip over the nozzle that results in efficient performance. Our nozzle heaters are ideal for use in hot-runner molds.
