Decontamination
Applications
UVC medium pressure disinfection system
- Compact and cost efficient UVC system to disinfect the surfaces of packaging materials
- Very high disinfection rate for germs like aspergillus brasiliensis or bacterius atrophaeus even with disinfection times of only 0,5-2 seconds
- Improved disinfection rates from log 2 – 4 for packaging materials and improved lifetime stability of the UVC
- Higher disinfection dose and less heat due to dichroitic glass reflector
- Less heat load on shutter, since shutter and reflector are independent from each other
- Improved design of the hygienic housing with innovative sealing of the quartz glass window and a new long life breakage detector
- Reduced noise level due to high system efficiency and a dimmed fan
- Electronics and mechanics proven since decades in printing machines
UV Ray & DR. FISCHER Group
Since Dr. Fischer became lamp supplier or UV Ray, the cooperation has grown far beyond this. Today DR. FISCHER supports UV Ray worldwide in the sales of its printing and curing equipment in many countries like Germany, France, Austria and French and German spoken Swiss. Besides this, both companies have developed together with their customers new solutions like the UVC system we present you here.
Worldwide exclusively distributed by the DR. FISCHER group.
The electronics, cooling and mechanics of the system are proven over decades of years in printing machines.
UV Ray and Dr. Fischer – a perfect cooperation for the UVC packaging disinfection
DR. FISCHER UVC solutions
UVC disinfection with low and medium pressure mercury lamps is used since many decades to reduce successfully germs in air, water and on surfaces, destroying their DNA. Dr. Fischer has developed lamps and systems for all these applications since more than one decade.
Room air disinfection units from Dr. Fischer can destroy the Corona virus up to 99,9% in one pass through for an air flow of 600 m³/h, certified by the microbiologic laboratory of the ISWA department of the University Stuttgart.

The fans
- UVC systems come with 3 different fans (0,75/1,5/2,2 kW) for 10/20 kW ballast in CE or UL execution
- All fans are food grade, stainless steel
- Fans are driven by lamp ballast
- If needed, one ballast can drive 2 fans in case of difficult cooling configurations
The control panels
- Can be directly connected to the ballast to control the UVC unit manually and reads out all service parameters
- With these HMIs all parameters of the UVC unit can be controlled as well as various parameters can be checked for service or remote operation/control
- HMI connects via internet for remote support
- The Touch HMI can run several UVC systems in parallel
The ballasts
- Power Options: Up to 10 & 20 kW (CE or UL execution)
- All-in-One Design:
- Includes ignition, lamp driver, fan frequency converter for air cooling, safety switch, controller (shutters & breakage detector)
- Programmable master card (compatible with Profinet, Profibus, etc.)
- UV Boosts:
- Dimmable from 30-100% in milliseconds via electronic ballast
- Automated standby mode at 30% when shutter is closed
- Smart Fan Control:
- Ballast adjusts fan speed based on power & temperature to reduce noise & energy consumption
- Modular Ballast Design:
- Enables eco-friendly repairs & remote failure analysis
- Optional UPS for safe shutdown of the low power control electronics in case of power interruption or emergency stop
DR. FISCHER air filter
- Cooling: Production air can cool the UVC cassette
- Protection: Air filter prevents raw dust particles from burning into the lamp or quartz glass
- Noise Reduction: Acts as a sound absorber, reducing fan noise in the production hall
- Options: Available with or without a filter mat (DR. FISCHER air filter)
