The Extechnology Ozone Converting Unit

One of the notable concerns regarding ‘UV' treatment in kitchen ventilation systems is the risk of residual ozone discharge at the point of extract.

Ozone is a strong oxidising agent and occurs naturally in our environment.  The use of ‘UV' treatment as a method of grease and odour control in a kitchen extract environment promotes the production of ozone.  Ozone is only harmful if exposed to over a prolonged period of time, eight hours. 

Kitchen extract environments use up the ozone which is produced by UV applications very quickly due to the volume of contaminated air and the reactive nature of ozone - However in sensitive installations where the dosage of ozone is relatively high and the risk of carry over is possible it is advised to treat the residual ozone before extracting it into the environment.   Extechnology have developed the EXS ozone converting unit for this particularly purpose. 

The EXS 12 lamp is a ‘stab in' duct mounted unit installed as close to the point of extract as possible.  The EXS 12 lamp contains ‘UV' tubes emitting ‘UV' light at a specific frequency aimed at converting all residual ozone back into oxygen before discharging it in to the environment.  The EXS unit ensures that all ozone levels are below the permitted PPM measurement as set out by DEFRA.
