Kitchen Exhaust Purification

Although the use of ecology units and ultraviolent tubes in commercial kitchen exhausts is common place found in this market, neither system provides a satisfactory solution to eliminating cooking smells and eliminating grease. Ecology units tend to large, heavy structures with a multi-filter arrangement which requires much energy and collect grease without neutralising smells. On the other hand, ultraviolent tubes deal reasonably well with grease, but they are maintenance-intensive and fail to neutralise smells.

For this reason, our Company has introduced an alternative Ozone based system, which is capable of:

.   Decomposing up to 95% of grease molecules in the exhaust air stream; and

.   Neutralising up to 90% of bad odour.

In addition our ozone system requires:

.   Less cleaning of hoods & ducts so less maintenance cost.

.   Minimum maintenance cost, compared with ecology units and ultraviolet tubes.

.   Minimum space for installation.

The various benefits or our Ozone based system are diagrammatically depicted below.Although the use of ecology units and ultraviolent tubes in commercial kitchen exhausts is common place found in this market, neither system provides a satisfactory solution to eliminating cooking smells and eliminating grease.

Shown below is a comparison of the Ozone system versus the alternative ecology and ultraviolet systems.

Other advantages of ozone system over other chemical alternatives are:

     .   Ozone oxidizes rapidly and decomposes equally fast to Oxygen leaving no traces.

     .   Ozone reactions do not produce toxic compounds.

     .   Ozone acts rapidly, and more completely than other common disinfecting agents.

In our system, ozone is produced in ozone generators, located near-by the kitchen hood(s). The ozone is transported in teflon tubes and injected above the hoods using special injectors. Purposely made controllers ensure the safe operation of the system at all times.

A typical configuration of our ozone based system in a multi-hood or single hood commercial kitchen exhaust is shown below.
