US deaths spark interest in UV

Following recent deaths in the USA from Bacillus anthracis, Hanovia has received many enquiries about the potential of UV to destroy harmful micro-organisms.

Following recent deaths in the USA from Bacillus anthracis, Hanovia has received many enquiries about the potential of UV to destroy harmful micro-organisms in the heating, ventilation and air conditioning systems of buildings.

The fact is that UV is already widely used in office buildings, hospitals and laboratories as an effective way of controlling airborne infections.

Following the introduction of a Hanovia unit within the air conditioning system of a call centre operator in Surrey, for example, the company observed a 40% reduction in staff absences due to sickness.

Compact and easy to install within existing ductwork, UV systems are silent in operation and can treat up to 6m3/s of air per UV lamp.

They are virtually maintenance-free, the only regular requirement being the replacement of the UV lamps twice a year, a simple operation that can be carried out by general maintenance staff.

Commenting on the current situation, Hanovia's Managing Director Jon McClean says, "Despite the obvious benefits of UV, it must be remembered that it should not be seen as a miracle cure, especially when dealing with serious pathogens like Bacillus anthracis.

It can only be effective when used as part of a comprehensive HVAC strategy which includes air filtration and proper ventilation practices, as well as sensible security measures".
