Twin Tube Short Wave Infrared Emitters

Gold Coating

White Plating

Clear without any coating

Twin Tube IR emitters are two IR emitters fused together as one. They deliver more power to a smaller area, thus creating a more powerful emitter. Additionally, each twin tube emitter utilizes a 180 degree back reflector that is coated directly on the quartz tube envelope. This coating material is a high purity gold substrate. Gold is the most efficient IR reflective material.

· 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

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 .

What is Short Wave Infrared Heater Lamps

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.This provides a very high energy source capable of responding instantly to voltage changes, allowing for precise temperature control for a variety of applications.

· Glass Tube:99.9% Pure Fused Silica Quartz Sealed

· Filament Material:Tungsten

· Filament Temperature:1800 - 2400C℃(3300 - 4400F)

· Peak Wavelength:1.0 - 1.4 Um

· Color temperature 2400~2500 K

· Response time around 1~2 seconds 

· Average working life 5000 hours 

· Vertical and horizontal emitters are available 

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.

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%

4.could you supply clamps for lamp installing ?

Yes, we will provide mounting clamps for clients, and the corresponding clamps quantity with purchased lamps are supplied freely bu us.

5.The lamp can be used in vertical Orientation?

Yes, it can be used in vertical basides in horizontal position,see as the below picture

The first step in designing or purchasing a Quartz element is determining if it is mounted in a horizontal or vertical position. Typically, Quartz elements are mounted in a horizontal position. This is the simplest design. However, some applications require the element to be in a vertical position. The only difference that makes in the design of the element is that the element coil cannot be stretched; it must be tightly wound such that it can support itself in a vertical position. This requires additional processing on the coil to form an insulating coating on the wire so there is no electrical contact between the turns of the coil. Vertical or Close Wound coils are not a problem for us. We can make these in any length, but due to the more stringent physical specifications of the coils, some designs may not be possible. Note: A minimum purchase is required for these elements due to the extra processing required.

6. Have an unusual design?

Send us a drawing, sketch, or sample and we'll be happy to quote it.

We specialize in small runs and custom designs, but can be highly competitive on large orders as well.

7. How does your factory do quality control

" quality is priority", we always and keep paying more attention to QC from the material purchasing to the lamps' packing. Our product have gained CE, ROHS, ISO9001.
