Condensation hoods

Jeven’s condensation hoods are the most effective hoods on the market for removing condensate water.

The Jeven condensation hoods has a unique water and vapor separation baffle structure, condensate separators and edge grip on both long sides.

Condensation hoods are intended for kitchens, where a large amount of water vapor is released from kitchen equipment, such as dishwashers. Thanks to the modular design of the hoods, they can be manufactured without partitions.

PRODUCT STRUCTURE

  1. Measurement tap for the supply air (behind the condensation baffles)
  2. LED lights
  3. Condensation baffles, measurement tap for exhaust air
  4. Supply air connection and damper unit
  5. Exhaust air connection and damper plates
  6. Supply air unit (detachable)

Light

By default, every hood module comes with an energy efficient LED light fixture integrated to the hood’s roof.

The light fixture has a cable which should be connected to a junction box with a cable lock. The connection cable is equipped with a quick connector and it must be positioned in such way that it is not exposed to mechanical or thermal stress.

FUNCTIONING PRINCIPLE

JSKI

  1. Dirty air rises due to temperature differences against the ceiling of the hood.
  2. Condensated water and grease are effectively removed by the baffles.
  3. Clean air is extracted.
  4. Supply air is introduced through supply air columns
  5. The supply air blowing pattern and blowing direction can be varied.

TECHNICAL INFORMATION - EXHAUST AIR

The recommended exhaust flow rate is max. 250 l/s per 315 mm spigot, duct velocity 3.2 m/s. The hoods are equipped with a suitable type of condensation baffles (pressure level 30-50 Pa).
The recommended exhaust flow is 100 to 200 l/s per hood meter. The hoods are equipped with a suitable type of condensation baffles.

Pressure loss and sound data

Condensation baffle type 1/1

Sound power level, Lw
Sound power level Lw in each octave band is computed by adding the corresponding factor, Kok to the sound power level LpA: Lw=LpA + Kok.

Effect of damper plate on sound level

In practice, the sound level will not increase if the pressure difference increases by 20 pascals or less. When the differential pressure rises, the sound level of about 45 pascals increases by about 5 decibels. Precise sound additions can be found in the design software (MagiCAD, CADS Planner Hepac).

TECHNICAL INFORMATION - SUPPLY AIR

The canopies are supplied from the factory with suitable air flow rates for a pressure level of 25-35 Pa.

Supply air blow alignment

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 an individual adjustment of air patterns and air flows, which means a better indoor climate for the kitchen staff.

Horizontal alignment of the supply air
The supply air blow direction can be aligned left or right by moving the air control plates inside the supply air units. The control plates are marked in red in the pictures.

Vertical alignment of the supply air
The supply air blow direction can be aligned up or down by turning the horizontal air control plates inside the supply air units. The control plates are marked in red in the pictures.

Air blow directions alignment nearby supply air column
Supply air blowing direction can be aligned by turning the rotatable blowing nozzles at the bottom of the supply air column. The rotatable nozzles are marked in red in the pictures.
