Suitable for heating large quantities of liquids and water solutions alkaline fuel oil, mineral oil and chemicals
Mostly used in ovens and tanks where draining is not possible to change the heater
We offer a wide range of cartridge heaters that are used where heat is required in limited space such as dies, plates, molds and packaging machinery etc. These are manufactured using high quality raw material like brass, S.S. and incoloy sheathing. Available in plain and 'D' type with low and high-density wattage, our heaters are best in the market and are offered at best industry prices.
Features:
Use of high purity magnesium oxide (MgO) insulation assures high dielectric strength & fast heat transfer efficiency
Designed for high watt density
Swaging increases the high thermal conductivity and uniform heating
We also manufacture a comprehensive range of mica & ceramic heaters that are used for proper contact heating on cylindrical surfaces. The entire range of heaters are made in M.S., brass and S.S. sheathing as well as in perforated sheathing for air-cooled applications. Available in custom specifications also, these heaters are covered with insulated jacket to save energy. We offer the complete gamut at very reasonable prices.
Features :
Mica heater is most economic
Provides excellent dielectric strength and thermal conductivity
Our product range also include best quality nozzle heaters as mica nozzle heaters that comprise of high quality heating element (windings) and nickel-chromium resistance wires. We offer these in one-piece as well as two- piece designs. The mica nozzle heaters and ceramic nozzle heaters are manufactured using superior grade raw steel, aluminum or brass and thus are completely reliable and durable in the given operations.
Features :
Manufactured using high quality steel, zinc or brass
High performance MI (mineral insulated) and heater
Ideal for every type of plastics processing equipment
Casing formed from a high strength material such as steel
A mounting block clamped to the nozzle
Inclusive of ground conductor
Mica or mineral insulation
Uniform and consistent heating
Specifications :
Maximum Watt Densities – 55 - 230 W/inch2
Maximum Operating Temperatures – 480 – 760o C (900 – 1400o F)
Coil heaters also known as cable heaters can be formed to a variety of shapes as required by its many applications. Frequently though, coil heaters are configured as small diameter, high performance nozzle heaters that are fully annealed. Coil heaters are also used as cartridge heaters where irregular size bores are found.
Applications :
Heated Nozzles
Hot Runners
Platen Heating
Injection Moulding
Aluminum Extrusions
Heat Sealing
Usage :
injection molding machine nozzles
sprue bushings
Their coil heaters supplying 360º of heat with optional distributed wattage models also available.
We manufacture and export world class thermocouples that are designed to sense accurate temperature at heated application site and transfer it to control meter. Manufactured using high quality raw materials, these offer most efficient service performance. We also work in compliance to the client's specifications to deliver products that meet their exact requirements.
