Brief introduction of Short Wave IR Heater
Short wave quartz infrared heaters are used in various industrial applications. It contains tungsten filament, helically wound, encased in quartz envelope. Tungsten as resistive element is capable of generating temperature in excess of 2750℃. Its response time is very rapid in 1 second it emits over 90% of IR energy. It is by products free & pollution free. Heat focus is very accurate due to compact and narrow diameter of IR tubes. Short wave IR element has maximum heating rate of 100w/cm.
The quartz envelope allows transmission of IR energy and protecting the filament from convective cooling and corrosion. Addition of small percentage of halogen gas in it not only increases life of emitter but also protects blackening of tube and depreciation on infrared energy. The rated life of short wave infrared heater is around 5000 hours.
Advantages of Infrared Radiation
|Infrared radiation unlike convection or conduction, dose not rely on any medium to transfer heat from infrared source to the object being heated, heat directly to the object
|no need medium transferring, quick response,can reach working temperature more quickly, heating by infrared emitters shortens process time and increases production rates
|low capital cost, easy installation, reliable operation, low maintenance costs and efficient use of energy.
Better product quality
|Controllable, predictable heating reduces wastage and promotes products quality
Clean, and no any pollution released to the surroundings
