Guidance on the Control of Odour and Noise from Commercial Kitchen Exhaust Systems is where KES Facilities limited come in to help. With past and present clients we have always found that product knowledge is exactly where we can help you achieve all area or council restrictions.
These filters comprise a number of interlocked vanes which when assembled, form a two-pass grease removal device. Grease laden air passes through the filter and by a series of forced changes in direction and velocity, the grease becomes separated from the air stream and is deposited on the vertical vanes
A basic filtration system can be used to deal with a low intensity odour problem, but more usually will form a protective pre-treatment step before an activated carbon step.
In-line Ozone and UV systems
Oxidation using ozone and/or activated oxygen ions has been used to treat odour emissions from commercial and industrial kitchen processes
ESP (electrostatic precipitator)
Electrostatic separators (ESP) are used to separate solid or liquid particles from ventilation air. The particles distributed in the gas are electrostatically charged so that they stick to collection plates.
Carbon adsorption (carbon filters)
Carbon filters are most widely used. Other materials used are: Zeolites, silicas and polymeric resins. Activated carbon systems are available that include impregnated oxidising materials e.g. chlorine dioxide or permanganate, although such materials tend to be more expensive. Adsorption is a dynamic process in which gaseous molecules impinge on the surface of the solid and remain there for a period of time before desorbing again in to the gas phase
