GIF UV-C(lean)

The GIF UV-C(lean) system is fitted with a new generation of UV-C lamps, having a higher output and energy, thereby giving greater efficiency within the same space.

UV-C(lean) systems work without the usual loss of efficiency, when operating in areas of raised temperatures. This means that the systems installed in extract canopies and GIF –Restaurant systems above grills and fryers function more efficiently and durably.

The UV-C(lean) control cabinet is a digital control unit with integrated operating status and fault monitoring systems with a compact and more user-friendly cabinet. It incorporates a large screen with a continuous display of system status including:

System operation – showing the cumulative hours the system has been operating and the cumulative malfunction hours (reset by the maintenance engineer when the tubes are changed)
System malfunction – the emergency telephone contact number is displayed
System maintenance – when the life span of the UV-C reactors is reached

The digital control unit enables the UV-C(lean) system to be modified at any time without complication, especially important if the system is enlarged to cater for additional cooking equipment or a more greasy style of catering is adopted.

There is virtually no limit to the size or scope of catering facility for which UV-C(lean) can be supplied.

Why should you choose to use a UV-C(lean) system?

The problems / dangers of grease build up in exhaust air systems:

When cooking, frying or roasting an extensive amount of grease and fat particles are carried upwards by the thermal current that is produced. A large quantity of these particles are then, as a rule, separated from the air through the use of filters such as those used in extract hoods or ventilated ceilings. Even with the use of high performance filters a 100% separation of the particles is not possible.

The result is a build up of grease and fat in the extract air ducts and their components.

Through this the fire risk increases substantially and can also lead to hygienic problems such as a build up of fungus (due to the nutritious fat deposits). A further problem which regularly occurs is unwanted smells in the kitchen exhaust air. These are not just caused by cooking, frying or roasting but are also caused by grease deposits on the inside of the extract air ducts.

Conventional Cleaning:

To be able to localise and remove grease deposits, the use of robots, high pressure cleaners and high quality chemicals is necessary. This is time consuming, expensive and has to be repeated at regular intervals.

The conventional way of cleaning solves the problems for a short period of time only and not completely as some parts of the duct system, e.g. due to a lack of inspection hatches, cannot be reached. Furthermore the aggressive chemicals used in conventional cleaning methods cause, especially in older duct systems, substantial corrosion problems.

Our Solution:

The UV-C(lean) system that eliminates organic fat and grease particles in the kitchen exhaust air by means of UV-C light.

Oils and fats are carbon-hydrogen compounds whose individual molecules are made up of several carbon atoms; these are simple or complicated compounds that are attached to each other.

By exposing greasy surfaces to intensive UV-C rays, a part of the energy from the UV-C light is absorbed by the fat and grease particles. Through this the molecules in the fat are put in a state of energetic movement which, in turn, makes an oxidation of the molecules substantially easier.
At the same time, due to the influence of the UV-C rays on the oxygen molecules in the air, Ozone, whose oxidation capabilities is much greater than that of normal oxygen molecules, is created.

These two processes cause an immediate oxidation of the fat molecules (a so called cold combustion). The resulting products of the oxidation are short-wave gaseous organic compounds (e.g. carbon dioxide), which are then conveyed to atmosphere by the extract air stream.
