New generation of UV high power lamps moves into Fast Food restaurants: UV removes the odors in kitchen hoods

Heraeus 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, the technological leader in UV light has developed a powerful UV lamp exclusively for Franke Foodservice Systems. Franke Foodservice Systems is the world’s leading provider of comprehensive systems and services for the foodservice industry. 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.

Optimized Heraeus UV Lamps for Franke Foodservice Systems
Heraeus Noblelight has developed a special vacuum-UV lamp (VUV) exclusively for Franke Foodservice Systems and this has been specially designed to match the conditions in Franke kitchen exhaust systems.

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.

When asked about the new technology provided by Heraeus, Chris Thompson, the head of New Product Development at Franke Foodservice Systems, says, “The Heraeus VUV lamp operates very effectively and makes our exhaust system even better and more economical. The UV radiation is dependable and easy to use.”

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.

Aerosol Treatment
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 80ºC, 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.

Unique internal coating ensures a long operating life
The unique Heraeus Longlife internal coating of the lamp tubes ensures a long lamp operating life. This Heraeus Longlife coating is also transparent to the very short wave, ozone-generating UV radiation at a wavelength of 185 nanometers. In this wavelength sector too, the lamp operating life is significantly extended compared with conventional technology to up to 12,000 hours.

Ever since the development of UV emitter technology in 1904 by Richard Kuech, Heraeus can look back on over 100 years experience in the development, production and application of UV lamps. With innovations such as the development of Longlife technology, Heraeus is setting down further milestones in lamp technology to increase productivity in industrial processes. Heraeus Noblelight is the original equipment manufacturer and the preferred partner for many systems manufacturers involved in the disinfection of water, air and surfaces, as well as for industrial photochemical processes and oxidization.
