An infrared heater or heat lamp is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the peak of the infrared radiation ranges from 750 nm to 1 mm. No contact or medium between the two bodies is needed for the energy transfer. Infrared heaters can be operated in vacuum or atmosphere. Arihant Electricals Manufacture, supply and export its infrared heaters in India as well as other countries.

 

One classification of infrared heaters is by the WAVELENGTH bands of infrared emission.

 

• Short wave or near infrared for the range from 750 nm to 1.4 μm; these emitters are also named “bright” because still some visible light is emitted;
• Medium infrared for the range between 1.4 μm and 3 μm;
• Far infrared or dark emitters for everything above 3 μm.

 

Applications

 

Infrared heater for cooking

IR heaters can satisfy a variety of heating requirements, including:

 

• Extremely high temperatures, limited largely by the maximum temperature of the emitter
• Fast response time, on the order of 1–2 seconds
• Temperature gradients, especially on material webs with high heat input
• Focused heated area relative to conductive and convective heating methods
• Non-contact, thereby not disturbing the product as conductive or convective heating methods do

 

Thus, IR heaters are applied for many purposes including:

 

• Heating systems
• Curing of coatings
• Space heaters
• Plastic shrinking
• Plastic heating prior to forming
• Plastic welding
• Glass & metal heat treating 
• Cooking
• Warming suckling animals or captive animals in zoos or veterinary clinics
