Cyclone Hoods

Jeven Cyclone Hoods are equipped with cyclone filters suitable for kitchens with lower purification requirements. A cyclone filter separates grease by sucking air into a circular chamber where it produces a vortex. Grease and other contaminants are thrown out to the periphery and the purified air flows up to the exhaust flue. Maintenance is very simple as the filter cells can be easily removed from their housing and cleaned in a dishwasher.

FUNCTION

JSI-R

Toimintaperiaate JSI-R

  1. Contaminated air rises up to the roof of the hood.
  2. It is then sucked in through a cyclone filter.
  3. The purified air is sucked into the flue.
  4. Draught-free fresh air is supplied to the room via demountable air supply units.
  5. Control air jets direct the odours towards the grease filters and prevent contaminated air from escaping from the hood.

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.

UV-Turbo hoods

Modern technology for demanding grease reduction in professional kitchens. UV-TurboHoods are equipped with TurboSwing filters which use ozone-free UV light. Purification using UV light reduces small particles by means of catalysis. Combined with TurboSwing filters, this purification method yields high separation rates for both small and large grease particles and is especially suitable for variable flows as the separation process is completely constant irrespective of flow.

Jeven Turbokåpor är utrustade med det effektiva TurboSwing®-fettfiltret. TurboSwing® fungerar genom att luften passerar en roterande, perforerad plåt där fettpartiklarna avskiljs mekaniskt.  TurboSwing® är tack vare sin höga avskiljning väldigt lämpligt i anläggningar med värmeväxlare. Tacka vare att avskiljningen är oberoende av flödet fungerar detta filter utmärkt i system med behovsanpassad frånluft.(VAV) [button text="Läs mer om TurboSwing®-fettfilter" size="small" color="secondary" style="outline" link="http://jeven.se/2009/10/13/turboswing-ett-nytt-revolutionerande-fettfilter-for-professionella-kok/"]

Condensation Hoods

The Jeven Condensation Hood is a hood that has been specially developed for handling condensed water in processes where there is an excessive build-up of water vapour. It is especially suitable over cooking pots where the raked ceiling of the hood prevents the droplets that form from landing in the cooking. The condensed water is led through the roof into a gutter where it collects. For kitchens with heavy loads, it may be necessary to install a drain for the condensation in the gutter and thus avoid overflowing.

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.

Cyklonkåpor

Jeven Cyklonkåpor är utrustade med cyklonfilter som är lämpliga i kök med lägre krav på rening. Ett cyklonfilter avskiljer fett genom att luften sugs in i en cirkulär kammare där det uppsåt en virvel. Fett och andra föroreningar slungas ut mot periferin och den renade luften strömmar upp mot imkanal. Underhållet är mycket enkelt då filtercellerna lätt plockas ner från filterhuset och rengörs i diskmaskin. Cyklonkåpor finns både som tilluftskåpa JSI, styrluftskåpa JVI och som frånluftskåpa JLI.
