| UV high power lamps moves into fast food restaurants  Heraeus Noblelight has optimized UV lamps for kitchen exhaust applications around the world manufactured by Franke Foodservice Systems: one high powered Heraeus lamp is able to replace multiple standard oxidization lamps; UV light breaks down grease, reduces odors, and reduces the potential risk of dangerous fire propagation; reduces the need for excessive cleaning. Heraeus Noblelight has developed a powerful UV lamp exclusively for Franke Foodservice Systems. The use of vacuum UV lamps in the kitchen exhaust prevents grease deposits from forming within the duct over time. This reduces the potential danger of fire propagation and saves on cleaning and service costs. UV radiation is an innovative and economical solution to this problem. Franke Foodservice Systems currently offers a plug-in solution for kitchen hoods and this featured multiple standard UV lamps, each of 40-100 Wattage in a quartz safety tube. In the next generation product, a single Heraeus VUV lamp will replace the multiple emitters. Heraeus has based the technology and the design of its VUV lamps precisely to the requirements of the Franke Foodservice Systems hoods. The lamps have been matched to the environmental conditions, such as the dimensions, air throughput, and especially the high temperatures within the kitchen hood. As a result the lamps represent a more compact system with the requirement of only one power supply. There is no longer any need for a quartz safety tube with this technology. Around ten percent of the electrical input power of 150 Watts is converted into VUV radiation at a wavelength of 185 nanometers, and the operating lifetime of these UV lamps is up to 12,000 hours. Franke Foodservice Systems is also offering the new system as a retrofit option for existing kitchen hoods. The system consists of the VUV lamp in a chassis with a control box. Franke has tested the system for fire safety and has carried out the required safety tests. The use of grease and oils in the kitchen leads to deposits in kitchen exhaust hoods and exhaust systems generally. As a result, there is a danger of fire and ever-lingering smells. The physical method of UV radiation is an economical alternative to cost-intensive manual cleaning and frequent filter exchange. By using special Heraeus UV lamps, ozone is generated from the oxygen in the environmental air within the kitchen hood. This is produced at the Vacuum/UV wavelength of 185 nanometers. Organic substances such as greases and aromatics are continuously "cold combusted" and broken down by the UV radiation and the ozone. The exhaust channel remains virtually grease-free, the danger of fire is significantly reduced and kitchen smells in the exhaust air are substantially lessened. Even at high air temperatures over a grill of up to 80 șC, the vacuum/UV lamps are effective. They are especially suitable for applications where food is fried or grilled with a lot of grease, such as in fast food restaurants. write your comments about the article :: © 2008 Construction News :: home page |
