Ceramic Infrared Heaters – Elmec Heaters

Ceramic infrared heating elements are efficient, robust heaters which provide long wave infrared radiation. They are used in a diverse range of industrial processes such as thermo forming, paint curing, printing and drying. They are also used very effectively in infrared outdoor heaters and infrared saunas.
Ceramic Infrared Technology
Ceramic elements operate in the temperature of 300°C to 700°C (572°F – 1292°F) producing infrared wavelengths in the 2 – 10 micron range. Most plastics and many other materials absorb infrared best in this range, which makes the ceramic heater the most efficient infrared radiant emitter on the market.
A range of aluminised steel reflectors are also available to ensure that most of the radiation generated is reflected forward on to the target area. For comfort heating utilising Ceramicx Ireland’s infrared technology

High density cartridge heaters - Elmec Heaters

Elmec High Watt Density Cartridge Heaters are manufactured with most advanced technology and quality raw materials, enables usage with high watts in small spaces and advanced manufacturing process ensures our heaters are vibration proof and thus ensures excellent reliability in heavy duty working conditions (Like Plastic Processing, Printing, Packaging and automobile industries where the heaters are subjected to heavy vibrations). 




The high performance is achieved by correct installation of the cartridge heaters. The perfect fitness of the heater in the hole facilitates good heat exchange between the surfaces of heater and mass to be heated thus increases the heater life and reduces energy loss.

WATT DENSITY VS FIT SIZE FOR CARTRIDGE HEATERS

Operating temperature of heater and fit size are major factors in determining the life expectancy of cartridge heaters.

Heaters from Elmec Heaters and Automation


ELMEC is one of the leading heatermanufacturer in India established by Mr G.Srinivasan in the year of 1973 Elmec design and manufacture Ceramic band heaters, Mica band heaters, Nozzle heaters, High density Cartridge heaters, Split type cartridge heaters, Low density cartridge heaters, Tubular heaters, Manifold heaters and Hot runner nozzleheaters, Micro coil heaters, Hot runner controllers, Leak proof nozzle heaters, High Watt nozzle heaters.

Elmec is also authorized distributor for Opkon, Maxthermo, Ceramicx, and Optris for the Products of Linear sensor, Linear Encoder, Rotary encoders, Pressure sensor, Melt pressure sensor, Temperature controllers, Infrared heaters, Infrared thermometers and thermal imaging systems and hot runner systems.

With over 37 years of experience in the field of Heaters, sensors and controller, Our Company had gained enough knowledge to assist our customers to select suitable solution for their demands.

We design and manufacture standard and tailor made Ceramic Band, Mica Band, Cartridge, Tubular, Hot Runner, Micro coil, Manifold, Hot Runner Controller heaters, heating Equipments and thermocouple.

These heaters are installed by careful hammering on the heaters along with square section grove over the manifold and pressed to hold the heaters in position and to get good surface contact, which results in good thermal exchange and increases the heater life and reduces energy loss. Any product that we Manufacture are deal with, we assure the quality and standard on it. We have improved and become more energy efficient. There are now many types available, including solar-powered, natural gas, propane and electric.

Infrared Heaters are also very energy efficient, because none of the heat that they produce is wasted. They heat the surrounding area by emitting thermal energy waves that are absorbed by the materials around it. Infrared Heaters are also great at spot heating certain areas that you and your family spend most of your time in.

The oil filled heater is a very effective heating unit. Its technology has been around a long time and has proven itself. The unit itself is basically a radiator that is filled with specially made oil that conducts heat. Also inside the unit is a heating element or coil that heats the oil to the desired temperature. All our heaters are tested for High voltage test up to 2000 Volts and merger 100 Meg ohms to infinity.

Highly compressed Tubular heaters are the most advanced heating solution for injection manifolds. The square section tubular heater allows excellent heat exchange between the surfaces of heater and manifold.

Here are some heaters given below:
Ceramic Band Heaters
Mica Band Heaters
Nozzle Heaters
Split Type Cartridge Heaters
Micro Coil Heaters
Hot Runner Heaters
Long Life Finned Air Heaters
Quartz Infrared Heating Elements
Tubular Heaters
Oil Immersion Heaters
High Watt Density Cartridge Heaters

WATT DENSITY VS FIT SIZE FOR CARTRIDGE HEATERS

Operating temperature of heater and fit size are major factors in determining the life expectancy of cartridge heaters. Select closest possible fit size for installing cartridge heaters for heating metal parts
ADVANTAGES
  • High watt density cartridge heaters make it possible to have high watts in less space without sacrificing lifetime.
  • Proof against shock and vibration.
  • Excellent heat transfer.
  • Maximum operating temperature 1400°F (750°C) on heater surface.
  • Our heaters are cylindrically ground to have better surface contact and minimum hole tolerance.
  • Leak proof Tig welded end cap prevents heater contamination due to the entry of any foreign materials.
INSTALLATION RECOMMENDATION
  • The tightest possible fit is recommended
  • Prevent damages to hole surface while removing the heater.
  • Excellent heat transfer.
  • For easy fitting and removing the heater and to improve heater conductivity, a very thin layer of assembly get should be used on heater surface and should not be in contact with cables to avoid short circuit.
  • Protect cables from physical damage, excess temperature and excess flexing etc.
  • Use suitable temperature controllers like PID controller with SCR, Thyristor, mercury relay or solid-state power controls to increase the heater life.
  • The sensor should be placed as close as possible to the heater (15mm).
  • Use largest possible number of heaters to reduce watt densities.
