Microwave UV


Microwave UV Technology: Disinfection, Sterilisation and Odour Control in harsh environments.

Microwave UV

Features and Benefits include:

  • No wires

  • Suitable for harsh environments (excessive humidity, temperature or aggressive chemicals)

  • Longevity of UV lamps - no degradation of electrodes

  • Low cost - using mainstream (cheaper) microwave components

  • Smooth operation - instant on/off/on as microwaves are switched on or pulsed

  • Design flexibility - multiple lamps energised from a single PSU,  available in various shapes and sizes

Microwave UV is a common name for UV Radiation which is generated by electrodeless UV lamps.

We specialise in the design of energy efficient Microwave UV Systems which benefit from our patented Microwave UV Technology.

These lamps are powered by electromagnetic waves - microwaves at a frequency of 2.45GHz. Microwaves are generated by a device called a magnetron. The microwave energy then travels through a waveguide and couples into a microwave cavity which contains one or multiples of electrodeless UV lamps.

Microwave UV is the ideal solution in applications where UV Radiation needs to be generated in harsh environments (humidity, chemicals and temperature) or where high power UV (either pulsed or continuous dose) is required. UV Curing is a typical application where high UV energy density is achieved on very small footprints, using medium pressure electrodeless lamps. Alternatively, Microwave UV Disinfection of liquids is a typical application where a high UVC dose is achieved by pulsing the microwave energy into a low pressure electrodeless lamp.


Electrodeless UV lamps are also ideal for cleaning in place (CIP) technologies, as no wires or high voltages are present within the Microwave UV modules.


Our patented technology has been recently licensed and we are working on bringing our advanced Microwave UV Disinfection Technology to the worldwide market.


Our portfolio contains:

Devices for UV Disinfection of air flow where a microwave cavity is part of the air-conditioning duct.
The bulbs can be placed either parallel (left image) or perpendicular (right) to the air flow.
