Pathogen Control

Harmful bacteria in drinking water has become a rising concern. Hiding in the nooks and crannies of building plumbing systems, water-borne bacteria (such as Legionella) multiply, becoming a public health hazard. In Europe, Legionnaires’ cases have been increasing quickly. By 2018, after a two year period the number of cases reported had increased by 60%.

The OASIS® QUASAR UVC-LED Water Treatment system uses UV-LEDs to protect people from Legionella and other harmful pathogens. Treating water at the point of dispense, QUASAR uses Light Emitting Diodes (LEDs) to generate high levels of UV photons. The rays are directed at viruses, bacteria, and other pathogens within drinking water to render those pathogens harmless in seconds.

Ultraviolet Water Disinfection

UV represents wavelengths that fall between visible light and x-ray on the electromagnetic spectrum. UV photons penetrate harmful microscopic organisms and damage the DNA, rendering them incapable of reproduction. (microbiologically dead)

UV-LED technology is used to biologically destroy harmful bacteria and viruses, without the use of chemicals or mercury-based lamps. The UVC-LEDs allow for instant full- intensity power, unlimited cycling, remote start/stop, and no heat transfer to the water.

Disinfection Where It’s Needed Most

OASIS’s Quasar is unique, as it is the industry’s only UVC-LED system that work directly at the point-of-dispense.

This means that there is no more remaining length of piping that can harbour bacteria or pathogens to infect the water. As an added bonus the UVC-LED disinfects the spout are [the exact dispense point]

  • Pathogen Control: UVC-LEDs disinfect the water when it is being dispensed, eliminating the chance of recontamination and reducing over 99.99% of pathogens.
  • Pathogen Inactivation: Effective against a wide range of water-borne pathogens, including Legionella and chlorine resistant micro-organisms such as Cryptosporidium and Giardia.
  • Chemical Free: UVC-LEDs provide physical treatment of water without the use of harmful chemicals or altering taste.
  • Mercury Free: Conventional UV lamps contain mercury, a hazardous material which requires special disposal. UVC-LEDs are mercury-free.
  • Freshield: Alcove plastic is manufactured with our exclusive silverbased antimicrobial compound to prevent degradation and deterioration caused by bacterial growth.
  • Extremely Low Power: UVC-LEDs do not transfer heat to the treated water.
  • Constant Protection: UVC-LEDs pulse on every 10 minutes for a short duration to keep the dispense point sanitized.
  • Fail Safe: Prevents water from dispensing if the QUASAR unit becomes disconnected or fails.
  • Long Life: UVC-LEDs will last ten years and more. UVC-LEDs are only on during water dispense or standby mode for constant protection.

How Quasar Works

Traditional UV vs UVC-LED

UVC-LED technology far outpaces traditional UV technology. Conventional UV lamps typically use between 5-200 mg of mercury per lamp, often requiring routine replacement due to the fragile quartz tube. UV LED lamps on the other hand are a much safer alternative as it is mercury-free.

Moreover, conventional UV while superior over chemical solutions, has a higher impact on the water temperature and causes fouling, thereby altering the taste of water. In contrast, LED technology is easier to maintain and use, with a longer lamp replacement interval.
