Main features
Designed to be used by assemblers, these tubes radiate in the infrared between 3 and 6μ. They are characterized by an emissivity close to 100% within this range, they show a low surface temperature, a high mechanical strength, and high corrosion resistance.

They are particularly suited for heating, drying, or polymerization of a large part of usual materials where they heat faster than the traditional convection heating. It is recommended to install them on a reflector.

Applications
- Drying at low temperature leather, wood, prints and dyes, paints, ceramic email, food, fish.

- Varnish Polymerization on metal in automotive, appliances and similar industries - Maintain temperature of products displayed or waiting in fast food and restaurants - Heating of plastics before forming
- Sterilization of medical devices and equipment or food
- Outdoor ambient warming
- Reheating workstation in workshop
- Heating of stabbles, poultry

Specifications RadiatingTube:
Material: Sintered silicon carbide, 3mm thickness.

Corrosion resistance: Higher than tungsten carbide and alumina, particulary at high temperature
High mechanical resistance to bending in 3 points: 550 MPa at room temperature (on 3 × 4 × 45mm rod)

Low-thermal expansion: 4.10-6 mm/MMK
High thermal-conductivity at 200°C: >100 W/mK
This high thermal conductivity guarantees outstanding temperature uniformity over the entire length of the tube, resulting in a well-focused wavelength of infrared radiation.

Heater assembly
Insulation resistance:
- Measured between outer tube and live part: >100Gohm (cold-state)
- Measured at 450°C between ceramic brackets and live parts: >20 Gohms
High-pot insulation: >2500V
Outside standard diameters: 12mm and 20mm. 14 and 17mm on request (MOQ apply) on request if the wavelength must be modified)

Warm up time: Less than 5 minutes (From room temperature to stabilization)

Heater wire: 80/20 Nickel Chrome wounded on quartz rod
Surface temperature: 400 to 450°C @ 25°C.

Electrical connections: Screw-in ceramic cap, stainless steel M4 screws
Mounting: Both ends of the tubes have an alumina ceramic section for fixing by clamps
Voltage: 230V standard. Other voltages on request (MOQ apply)
Options: Several tubes grouped side by side on the same surface, or on a cylindrical surface to achieve radiant panels.
