Short Wave Infrared Heater Lamps

Short-wave infrared emitters utilize a low-mass tungsten filament that is incased in a special blend of inert gasses. This provides a very high energy source capable of responding instantly to voltage changes, allowing for precise temperature control for a variety of applications.

Gold Coating

White Plating

Clear without any coating

This is made up high-purity clear quartz twin tube, each tube has Heating Coil of Tungsten material which runs in U shape in the tube which is filled with halogen gas.

· Power Density up to 20KW/m2 is achieved. Heating up and cooling down time is approximately one second

· These heaters are available with gold reflector and without reflector

· Reflector is in the form of gold/ceramic white coating on outer rear side of the tube

· Due to reflector heat loss from backside is prevented and thus power saving is achieved

· This also results in making surrounding work area cooler

· This also increases the efficiency and directionality of the heater

· There are two standard sizes 11 mm x 23 mm and 15 mm x 33 mm in cross section. Maximum length available is 4600mm

Information of Short Wave Infrared Emitter

1.

Tungsten Wire Filament 

The high-density infrared energy is produced by a tungsten wire filament in the lamp. The filament is supported by tungsten wire ring anchors, tantalum disks, or through deflection winding of the filament to create the support from the filament itself. The supports prevent the filament from coming into contact with the quartz lamp envelope and causing the lamp to fail.

Atmosphere

The inert atmosphere in the quartz glass envelope protects the tungsten wire filament from oxidation.

2. Applications

3. Rapid Response

The lamps heat up and cool down instantly in response to changes in applied voltage. They radiate 90 percent of the available radiant energy in less than one second after being turned on. By comparison, long wave length infrared emitters must be energized for several minutes before they reach the same relative output. Similarly, the short-wavelength infrared emitter in the lamps cools down much faster than a long wave length infrared emitter. This is in part due to the greater thermal mass of long wave length emitters.

4. Electrical Connections

In most cases, connections to supply electricity to the tungsten wire filament are made through flexible pigtail leads. Button contacts and screw bases are also used on some lamps to make this connection. Lamps with end leads should be installed so the leads have a small amount of slack to allow for thermal expansion during operation. This will eliminate lamp failure caused by rigid leads transferring this expansion to the quartz glass envelope

5. Reflector

The gold/ ceramic coating can concentrate the heat, increasing the effectiveness of the heat output. 
The emitters with coating are highly economical, converting practically all the consumed electrical power into heat.

For the emitters with high watt density or the surface temperature of the tube above 800°C , we suggest to use ceramic coating as reflector because the temperature resistance is up to 1000°C .

In addition to 180° (half-tube) coating, we also manufacture 270° coating or other customer specified degrees.

7. Advantages

Quartz glass infrared emitter frequently prove superior to conventional heating sources such as warm air,steam,ceramic,gas or metal emitters,because they transfer large amounts of energy very quickly and can be precisely matched to the product and the manufacturing step -the ideal heating process.

-Infrared radiation requires neither contact nor intermediate transfer medium

-Quartz glass infrared emitters are precisely matched to the materials to be heated

-Fast response times allow controllable heat

-Heat is applied precisely where and only for so long as it is required

Compared for example to warm air heating ,this often means less energy consumption,higher line speed,a smaller footprint and better result .

RFQ

1.Why Quartz Glass as the one main of material?

The choice of quartz glass is not a coincidence: this extraordinary material is totally transparent at IR radiation, can withstand constant working temperatures of more than 1000°C and it is resistant to chemical corrosion.

2.Typs of Quartz tubes

Quartz uses two kinds of quartz tubes: single tube and twin tube. The twin tube provides the best mechanical resistance, thanks to its reverse "H" shape, and it allows to manufacture emitters up to 6,5 meters in length.

3.Why Reflector

Industrial infrared heaters sometimes use a gold/white/ruby coating on the quartz tube that reflects the infrared radiation and directs it towards the product to be heated. Consequently, the infrared radiation impinging on the product is virtually doubled. Gold is used because of its oxidation resistance and very high IR reflectivity of approximately 95%
