DESCRIPTION AND OPERATION
The VIANEN stainless steel combined ceiling solution is used to cover kitchens containing a mixture of both
light and heavy-duty equipment. Where heavy cooking activity occurs, producing seriously contaminated
air, a plenum is integrated into the Spantile ceiling. The FECON filters in the Plenum are capable of handling
and filtering the high volume of exhaust air required for the heavy kitchen equipment.
The filtrated residue is collected in an integrated channel within the plenum and is washed down by the
automatic washing system of the ceiling.
The VIANEN combined ceiling ensures optimal ventilation of the kitchen area regardless of the heavy-duty
cooking equipment. In this system Vianen combines both aesthetics and technical know-how to obtain the
best solution and low maintenance costs for the end user.
The VIANEN Spantile Ventilated Ceiling system consists of three different cassette types all fabricated in 304
stainless steel 1.00 mm thick. All visible surfaces are ultra-fine grain polished (320) and polythene protected
during transport. The cassettes are available in the following configurations:
1 ACTIVE CASSETTE – double skinned
curved active cassettes (with extract air passages) to extract vapour and grease designed to handle
125 m3/h (0.035 m3/s) per cassette.
2 PASSIVE CASSETTE – single skinned curved passive cassettes (closed) are positioned in the ceiling where exhaust
or supply air is not required.
3 SUPPLY CASSETTE – single skinned curved supply cassettes (with supply air passage) designed to supply
100 m3/h (0.027 m3/s) per cassette.
Each cassette measures 500 x 500 mm and features a lip and groove so that adjacent cassettes clip together
to form a chain effect. This facilitates easy handling and removal of the cassettes for cleaning purposes.
The cassettes are supported by a full-length stainless steel bracket assembly which incorporates an anodized
aluminium grease collection profile.
