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 3x4x45mm 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.
