GIF: Demountable Ventilated Ceilings

Principle of operation

GIF ventilated ceilings operate as overall surface supply and extract fields. The individual cassettes separate fat and condensate by harnessing the physical phenomena of moment of inertia and condensation. The 3-phase separation chambers are so constructed that dirt, fat and other suspended particles settle on the inner faces of the small registers. By using standardised, removable cassettes, access to all services passing through the plenum is straightforward.

Luminaires

The integral, flush fitting luminaries are fitted with damp proof fittings to IP54 standard – also available to P65.

In extract ceiling zones, luminaire diffusers are protected against a build-up of fat or dust by a curtain of fresh air provided by a connection to the supply air duct.

Extract ceiling

Fat and steam particles as well as the thermal loading of the room are effectively captured and removed by virtue of the arrangement of extract cassettes over a wide area. The design of the cassettes eliminates the formation of water and fat droplets.

Dirty cassettes are easily removable from the grid for cleaning in the dishwash machine.

GIF – Restaurant system

The GIF-Restaurant system provides concentrated extraction and compromises heavy duty cassettes, blank tiles and fat collection channel within a dropped frame. It is specifically designed for those particularly intensive kitchens with extremely high fat and steam vapours encountered in the preparation of haut cuisine menus.
Advantages include:

• Concentrated extraction above vapour intensive equipment
• Extended cleaning intervals
• Simple installation and removal of cassettes
• Optimum hygiene and durability of stainless steel

Supply air ceiling

According to the characteristics of each kitchen, supply air is provided either by GIF active cassettes or, in the case of lower air change rates, GIF flat supply air cassettes. Both systems guarantee absolute freedom from draughts since fresh air is introduced over a wide active ceiling. Even at low temperatures optimum air flow streams are assured. A uniform ceiling grid is thereby maintained.

The components for a comfortable kitchen environment are:

• Active cassettes for supply and extract air
• Acoustic cassettes
• Flat supply air cassettes

By combining the use of these with special, heavy duty cassettes and blank tiles in the GIF-Restaurant system, so optimum solutions for each installation are created.
