Dishwasher hoods

Jeven Dishwasher Hoods are designed to remove damp air and heat from dishwashers in dishwasher rooms. Dishwasher Hoods are available with sealing collars and grilles or with JPT condensate separators.
The JPT condensate separator has been developed for hoods over dishwashers where there is a lot of water vapour.

CONSTRUCTION

JPT condensate separator (JSDI-JPT, JDI-JPT)
Sealing collar with removable grill (JSDI, JDI)
Exhaust connection.
LED-lighting.

Lighting

As standard, the hood is supplied with recessed LED lighting prepared for DALI control.

The lighting fixture is delivered with a cable for connection to a junction box.

FUNCTION

Dishwasher hood with supply air JSDI-JPT

Contaminated air rises to the roof of the hood.
Since the JPT condensate separator air inlet is located at the roof of the hood, the hot and humid air is quickly sucked out through the condensate separator.
Control air jets direct the air towards the condensate separator and prevent humid air from escaping from the hood.
The exhaust air passes on into the flue.
Fresh supply air is supplied to the room draught-free via removable supply air units.

The noise power level (Lw) divided into octave bands is obtained by adding the correction factor
Kok with actual noise level (LpA) Lw = LpA + Kok

Diffusion image from the supply air diffuser

The diffusion and flow of the supply air is readily adjustable, which makes possible a draught-free supply of fresh air.
Since supply air diffusers can be placed on all sides of the hood, air can be supplied to anywhere in the kitchen.
The number of supply air units is determined by the total flow to be supplied to the hood.
The supply air diffusers are easy to disassemble for cleaning in a dishwasher.

Adjustment of horizontal diffusion image
Lateral air-flow can be regulated by adjusting the position of the diffuser’s vertical control plates.

Adjustment of comfort nozzle
In each supply air diffuser, there is a comfort nozzle that can be adjusted to give the kitchen staff extra supply air.
