Superior efficacy. Built-in safety

R-Zero is revolutionizing indoor spaces with industry-leading UV-C disinfection products.

Our best-in-class solutions inactivate 99.9% of microorganisms in the air and on surfaces in real time. Arc, Beam, and Vive dramatically increase effective ACH with both lower energy consumption and a minimized need for chemical disinfection products. R-Zero's efficacy data is backed by third-party labs and hundreds of happy customers.

UV-C is a proven method of disinfection for air and surfaces, used in a wide range of industries around the globe for safe indoor spaces. Each of our devices is designed and engineered for maximum safety.

Beam is an upper-room ultraviolet germicidal irradiation (UR-UVGI) device that works in occupied spaces to disinfect indoor air safely. Beam operates autonomously with passive technology and requires almost zero behavioral changes from occupants.


Beam Safety

  • Beam is mounted 7’ or higher in the room to ensure the effective dose of UV-C light (265nm) in the Upper Room does not reach occupants in the room.
  • After installation, each Beam is individually commissioned by a trained technician to ensure all areas of the room are in accordance with regulatory and industry guidelines set by the ACGIH. R-Zero ensures UV levels in all areas are safe for the skin and eyes.
  • As the only LED-based UR-UVGI product in the market, Beam is unique in that the intensity of UV-C can be calibrated to ensure maximum efficacy while maintaining safety for all occupants.
  • Two disinfection zone sensors (DZPIR) are located above the baffle on either side of the LED light bars. These two sensors detect motion above the baffle, in the high-intensity disinfection zone. When motion is sensed in the upper room disinfection zone, the DZPIR immediately stops the disinfection cycle. Beam will stay in a paused state until the DZPIR no longer senses motion to ensure that the area is clear.

Using 222 nm UV-C light, also called Far UV, Vive is a versatile device that works autonomously to inactivate harmful microbes from both air and surfaces while remaining safe for human exposure.


Vive Safety

  • Vive emits Far UV-C light (222nm) which doesn't penetrate the outer layers of skin or eyes, so prolonged exposure is safe for humans.
  • The ACGIH has set a threshold limit value (TLV) as a recommended maximum dosage for humans over an 8-hour day. The current TLV for human eyes is 161 mJ/cm2. Vive can detect the presence of people and is programmed with a daily run time limit to ensure it will not exceed the current TLV under any circumstances.
  • R-Zero manages the installation of Vives, including all safety commissioning to ensure they do not exceed the established TLVs and meet all safety and regulatory requirements in each space they are deployed.
  • It is always safe for people to be in the room with Vive as any potentially harmful irradiation is filtered out using a monochromatic filter.

Arc is a mobile UV tower that inactivates microorganisms in unoccupied rooms. In as little as seven minutes, Arc works to disinfect a 1,000 sq foot space so that it is ready for occupants to reenter.

Arc Safety

  • Because 254nm UV-C light is not safe for human exposure, Arc includes redundant safety features to ensure absolute protection in operations all of the time.
  • There is a built-in 30-second delay upon starting a cycle to allow the operator to exit the room.
  • 4 PIR safety sensors trigger an automatic shutoff if they sense heat or motion, indicating someone is within 40 feet of the tower.
  • All devices ship with warning signs in both English and Spanish to be placed outside the room while the device is running.
  • All Arc operators will be trained and certified upon purchase by the R-Zero Customer Success team to ensure safe Arc operation.
