High Watt Density Split Sheathed Cartridge Heaters uses less power, runs moreefficiently and survives more that that of cylindrical type conventional Cartridge Heaters. Due to its elongation capability it clutches the mould when energized leaving no air gap and contracts when it cools down parting the following advantage.

Bolt Heater is designed primarily to pre-heat large, drill holding bolts or studs. The Bolt Heater is used in the assembly or servicing of hydraulic presses, turbines or other equipment where a high concentration of heat is needed to expand, then wrench tighten tie rods. The parts cool and contract, resulting in the nut being drawn even tighter. A terminal box of octagon or circular shaped is fixed on the top where the terminals are provided and an insulated wooden handle is provided for shoving the heater inside/ outside the tunnel.      We manufacture Bolt Heaters in the form of Split Sheathed Heater complete with Terminal Box & holding and an insulated wooden handle. 

 

The heater in ESP hopper are provided to avoid clinker formation of the ash being collected at the bottom of ESP. Whereas the heaters provided at the shaft and support insulators are required to maintain the temperature above dew point which lies between 80-115 deg C. If temperature falls below the range as mentioned there will be a continuous tracking of electrical field over the surface of insulator which will result into damage of insulator and non availability of field for collecting the fly ash. We in Heatco after continuous R & D detected the importance of the Heating Elements for ESP and as per the requirement developed the Heaters for its smooth functioning. We are providing some of the types of heating elements provided at hopper and support and shaft insulator.

Heatco make Low Density Cartridge Heaters design consists of helically wound resistance coil made from nickel-chrome wire, evenly stretched and strung through holes in a round ceramic insulator. The element assembly is inserted into a Chrome Nickel Steel sheath through round insulators. This alloy provides the best combination of physical strength and resistance to heat oxidation up to 3000c. Fused Magnesia is used to fill all remaining space inside the ceramic insulator to increase thermal conductivity, dielectric strength, and provide longer operating heater life.

Maximizes Heat Transfer
Easy Maintenance
Reduces the Cost of operation.

The construction of Heatco make High Watt Density Split Sheathed Cartridge Heaters eliminates ceramic cores typically found in conventional cartridge heaters. Heatco with its continuous in house research and possessing highly-specialized manufacturing techniques compacts fused magnesia around the heater coil in such a way that increases dielectric strength and heat transfer away from the coil which results in significantly longer heater life. The heaters contract when de-energized, eliminating bore seizure and the need for expensive drill-outs.

Advantages High Density Split type Cartridge Heater:
Easily Replaceable

HEATCOmakeRefractory Charged replaceable type Cartridge Heatersare made from Ceramic Insulators which are for used for both Vertical & Horizontal operation.

The heating elements are fitted inside the bobbin of the ceramic insulators as per the rating & the voltage provided by the client for their use. A tie rod is fitted in between which keeps the ceramic insulators in line with the element.

The connection is made from Brass or SS as per the current drawn.

These Refractory Charged replaceable type Cartridge Heaters are housed in a metallic sheath as per the functioning of the heaters. While placing orders for such type of Heaters the clients must confirm the following:

Place of Use.
Mode of Operation.
Rating ( Watt) & Voltage.
Terminal Block details.
Dummy or Non Heating Zone.

HEATCOmakeREPLACEABLE CARTRIDGE HEATERSare made from long-lasting and high quality refractory materials which are mounted horizontally in a metallic tube as per design to suit its application. These are easily replaceable once the Cartridge Heater gets worn out. In standard production the heating element is made from Kanthal or Nickel/Chrome heating elements.

Heatco make Ceramic Band heaters are made of helically wound Nickel Chrome resistance coil precisely stretched with uniform spacing and inserted through ceramic cores forming a flexible heating mat. It is then placed in flexible stainless steel housing and terminated.
Owing to its flexibility these heaters are very flexible and can be fitted easily. Our Ceramic band heaters are available with different terminal styles, are fully flexible, and can accommodate holes and cut-outs.

We are into the manufacturing of hopper heaters; these can be availed by our customers easily at affordable prices. Ferrite core based high frequency transformer rectifier (HFTR) unit is a high voltage switch mode power supply (SMPS) unit for electro static precipitator (ESP).

Circulation heaters are the most common types of electric heaters used in the process industries. Tubular elements are welded into a flange to form the heater. One of the most important criteria for designing an immersion heater or a circulation heater is to choose the proper watt density of the heating elements. The liquid, gas, or solid that you are heating must have the correct watt density to ensure that the heater is safe, properly sized, and have a long life.We have experience in a wide variety of applications from water, oils, and steam to chemicals and hydrocarbon gases. We carefully engineer sheath and vessel materials to the application using appropriate watt densities to maximize life, yet minimize footprint. HEATCO has been supplying and have the capability to supply Circulation Heaters with 110 to 440 VAC as well as wattages from 500 watts to 230 KW. If required, HEATCO will configure circulation heaters with voltages and wattages outside these parameters.For more information on special voltage and wattage configurations, contact your HEATCO representative.These arecomplemented by HEATCOs experience in custom engineered solutions. Baffles mounted on the heating element bundle enhance and/or modify liquid or gas flow for better heat transfer. For critical sheath temperature and low flow conditions, baffles may be required.Contact your HEATCO representative for details.
