Up to ten times higher UV power density compared to conventional low-pressure mercury lamps
Mercury amalgam UVC systems provide powerful and reliable solutions for continuous air and surface disinfection in industrial processes. Their high UVC output makes them suitable for applications ranging from food packaging and conveyor belt disinfection to air and exhaust treatment. Designed for long-term industrial use, the systems combine efficient UVC technology with low maintenance requirements and can be adapted to specific process and installation conditions.
Amalgam UVC disinfection systems

BlueLight Premium – UVC system for food packaging disinfection
BlueLight® Premium UVC systems are designed for reliable disinfection of a wide range of food packaging. Amalgam low-pressure technology provides intensive UVC treatment with comparatively low thermal impact, making it particularly suitable for packaging used with temperature-sensitive fresh products.
Available in different sizes and power levels, the systems can also be retrofitted into existing filling and sealing equipment. Long lamp life, high irradiance and low maintenance requirements support economical production processes.
Typical applications are sealing foils, cups and buckets, pouches, gable-top cartons, packaging for yogurt, milk and other fresh products.
Features
- Cold, dry and chemical-free UVC disinfection
- Amalgam low-pressure technology
- High irradiance
- Low thermal impact on packaging
- Maximum lamp warm-up time of 90 seconds
- Lamp breakage detection
- Long lamp life
- Low-maintenance design
- Can be retrofitted into existing filling and sealing equipment
BlueLight SteriBelt – UVC conveyor belt disinfection system
The Excelitas BlueLight® SteriBelt is specifically designed for surface disinfection of conveyor belts. Particularly in meat processing, the system supports demanding hygiene requirements by providing continuous, chemical-free treatment of the belt surface.
Its flat amalgam lamp geometry concentrates more than 50% of the emitted power directly onto the target surface. Different system lengths accommodate various conveyor widths and facilitate retrofitting into existing production equipment.
Typical applications are food processing conveyor belts, meat processing and packaging and bottle sealing caps.
Features
- Flat amalgam lamp technology
- Peak emission at 253.7 nm
- More than 50% of emitted power directed onto the target surface
- Chemical-free process
- No external air or water cooling required
- Washable IP67 design
- Shatter protection with high UV transmission
- Easy lamp replacement and maintenance
- Different system lengths available
- Easy retrofit into existing production equipment
- Efficiency can be measured and documented
Air D – UVC air disinfection system for HVAC systems
The Excelitas Air D is a modular UVC system for continuous air disinfection in HVAC, ventilation and recirculation systems. Modules are installed directly into existing supply-air ductwork, treating the passing air with ozone-free UVC radiation at 254 nm.
Its slim profile creates virtually no additional pressure loss within the duct. Four module lengths and the ability to install multiple units side by side allow the required UVC dose to be adapted to airflow and application requirements.
Features
- UVC air disinfection at 254 nm
- Ozone-free operation
- Direct integration into existing supply-air ducts
- Slim profile without significant additional pressure loss
- Four module lengths available
- Modular scaling using multiple adjacent units
- Suitable for humidity levels up to 85%
- Low maintenance requirements
- Chemical-free air treatment
Smart Vacuum UV Control – VUV system for commercial kitchen exhaust treatment
The Excelitas Smart Vacuum UV Control System is designed to treat grease-containing aerosols in commercial kitchen exhaust systems and hoods. High-performance VUV lamps emit at 185 nm, helping to break down and neutralize grease and odors in the exhaust air.
This can reduce grease deposits in hoods and exhaust ducts, helping to lower fire risks as well as cleaning and maintenance requirements. According to Excelitas, one high-power VUV lamp can replace four to six conventional low-pressure lamps. Longlife coating provides an effective operating life of up to 10,000 hours.
Features
- VUV radiation at 185 nm
- Reduces grease and odors in kitchen exhaust air
- One lamp can replace 4–6 conventional low-pressure lamps
- Up to 10,000 operating hours with Longlife coating
- Digital status display
- Remote maintenance and fault diagnosis options
- Space-efficient system design
- Easy installation and cleaning
- Lamps suitable for ambient temperatures up to 80 °C
