JSKI Condensation Hood with Supply air
PRODUCT DESCRIPTION
The Jeven JSKI condensation hood has been designed for
kitchens where a comfortable, productive and healthy
indoor climate is required.
The JSKI canopy offers draught-free and drip-free
ventilation with first class working conditions and thermal
comfort.
JSKI is equipped with exhaust and supply air with damper
plates and measurement taps. Supply air is introduced into
the kitchen by supply air columns.
JSKI has special condensation baffles. Supply air columns
ensure that the distribution of supply air is controlled and
flexible.
Modularity makes it easy to vary both the number and
positioning of the supply air columns.
The actual supply air pattern can be manually adjusted
when working near to the canopy.
Supply air columns and condensation baffles are easy to
wash in a dishwasher.
LIGHT AND FILTERS
All Jeven condensation hoods are equipped with lights and
condensation baffles.
MATERIAL
The basic material of condensation hood is stainless steel
(AISI 304).
ACCESSORIES
Covering boards to enclose the area between the top of the
hood and the ceiling.

POSITIONING
The size of the canopy is determined by the size of the
kitchen equipment. The overhang depends on the type of
equipment and the distance between the hood and the
equipment. For this type of equipment, the overhang
should be at least 300 mm.
The typical distance between the hood side and the floor is
2100-2200 mm.
If the equipment has any doors that open upwards, make
sure there is enough distance to the canopy.

DISTRIBUTION OF SUPPLY AIR
LIGHTS
Jeven supply air columns deliver a controlled and flexible
distribution of the supply air.
It is possible to wash the supply air columns in a
dishwasher and the inside of the supply air chambers is
easy to clean.
These columns allow individual adjustment of air patterns
and airflows, which means better indoor climate for the
kitchen staff
