How the Spectral Blue system works

System overview

The Spectral Blue™ surface disinfection system consists of three parts:

  1. Spectral Blue disinfection devices
  2. Control automation, that switches between regular lighting and disinfection mode automatically.
  3. Photocatalytic coating.

The disinfection devices provide the disinfecting MWHI blue light that eliminates pathogens from the room air and from surfaces.

The control automation is optional, and means any switches, presence detectors and timers that you may use for controlling the device activity during the day. Most devices are DALI-equipped, allowing smart and flexible configuration. Alternatively you can just have regular on/off switches or devices with a wall plug.

The photocatalytic coating is an invisible, antimicrobial and dirt-repellent surface coating, that improves the antimicrobial performance of the system. With the coating the Spectral Blue system can eliminate pathogens in already 15-30 minutes (up to 99% reduction). The coating is based on nanotechnology, and it is virtually invisible and therefore does not change the appearance of your premises.

Continuous disinfection - Blue light keeps facilities hygienic 24/7, not just once per day

Antimicrobial effect of the Spectral Blue system

The ability of blue light to destroy microbes is based on its ability to energize naturally light-sensitive compounds inside the micro-organism, so that they start producing reactive oxygen radicals. Reactive oxygen species (ROS) are molecules containing very reactive oxygen, causing the bacteria to damage and destroy internally.

Spectral Blue - the effect of blue light on microbes

The efficiency of blue light can be further enhanced by applying the Spectral Blue photocatalytic coating on surfaces. The coating utilizes a phenomenon known as photocatalysis: energy of blue light starts a chemical reaction on the surface, producing short-lived Reactive Oxygen Species (ROS). The ROS disintegrate all microbes, including viruses, on the surface.
