These tubular quartz infrared lamps are high-powered heat sources incorporating a tungsten filament within a quartz envelope. The lamps are of the halogen type, which avoids blackening of the tube and consequently infrared depreciation during lifetime. Infrared HeLeN glare reduction lamps have a coating to reduce the visible glare, improve the colour rendering and raise the infrared output compared to existing zone heating lamps. They are highly economical, converting practically all the consumed electrical power into heat. The improvement (W/m2) is over 10-30 % compared to conventional ruby sleeve and neutral density infrared lamps in existing luminaires. These lamps feature a substantially lower visible glare level even than ruby and neutral density zone heating lamps. |
They have a narrower diameter (cf. ruby sleeve) for better optical systems and better colour rendering/less red colour appearance than ruby sleeve. Heat transfer is not affected by draughts or air movement and is noise-free. There is no by-product of combustion or movement of air or dust, thus giving a cleaner environment, and no oxygen is consumed, so no extra ventilation required. Infrared HeLeN glare reduction lamps comply fully with the IEC standards.
Applications
- Zone heating in: factories, sports halls, exhibition halls, work areas, churches, large halls, warehouses, storage areas, garages, terraces, greenhouses, open air applications, stadiums, camp sites, de-icing, etc.
- Process heating in: paint drying, etc.
