Seeing the UV light

Published: 1-May-2004

UV technology to destroy micro-organisms in air and water is widely used in the pharmaceutical sector, but keeping the surface of the lamps clean to ensure optimum effectiveness is costly in terms of downtime and lost production.


UV technology to destroy micro-organisms in air and water is widely used in the pharmaceutical sector, but keeping the surface of the lamps clean to ensure optimum effectiveness is costly in terms of downtime and lost production.

Now Braintree-based Carier Bulk Materials Handling has developed a self-cleaning system that is compact, easy to install and economic to operate.

It consists of a revolving cleaning head placed around the lamp that moves slowly along its length. Inside the cleaning head is a photocatalytic oxidiser that is activated by the UV light from the lamp to remove any residue from the surface. The system is self-monitoring and is activated when a trigger level is reached.

The company's series of Safe Guard UV water disinfectors can handle throughputs from 40m3/hour up to 50m gallons/day.
