The Essentials of Kitchen Ventilation – Understanding Kitchen Ventilation
Exact measurements of the performance of extractor hoods and air supply units are essential for the functionality of kitchen ventilation! Find out which equipment is used for this purpose in the new flyer “Understanding kitchen ventilation correctly”: Understanding Kitchen Ventilation
In commercially used kitchens, on the surfaces of the cooking equipment, some of which are very large, such as frying pans or fryers, an upward rising thermal air flow with pollutants is formed. To capture and extract this airflow with a high efficiency, kitchen ventilation hoods are installed above the cooking appliances. However, it must be noted that the air stream to be extracted is injected in the same ratio again as fresh supply air in the kitchens room.
However, this injection of fresh air often causes serious errors in the ventilation design! Firstly, a workplace in commercial kitchens is not comparable to conditions of, for example, open-plan offices or concert hall and secondly, it is of considerable importance that the thermal air flow described above is not disturbed by the introduction of the fresh supply air when it comes from the cooking equipment. Often the horizontal injection of fresh supply air has a negative influence on the rising thermal air flow and this is then blown out together with the pollutants from the kitchen ventilation hood, so that the hood can no longer cleanly suck the pollutants. The primary objective of REVEN fresh supply air products is a completely vertical, low-impulsive and laminar introduction of fresh air from top to bottom, without disturbing the reverse flow of the thermal airflow from the cocking equipment.
In order to make this possible, REVEN has recently started a research project together with the SCHAKO Group’s CFD competence center at SCHAKO IBERIA S.L.. Many manufacturers in the commercial kitchen ventilation sector are claiming that their products for the supply of fresh air have no negative effect on the capturing and sucking of the thermal air flow. However, to date, hardly any manufacturer has really known and truly analysed that on CFD systems and in fluid flow laboratories. For this reason, REVEN together with the CFD competence center of the SCHAKO Group started these analyses in the first quarter of 2018, see the video from above. More detailed results will follow shortly.
“Eierlegende Wollmilchsau” is a German expression for an all-in-one device which serves every purpose such as a Swiss army knife. Literally translated, it would be an “egg-laying wool-milk-sow”, “a hypothetical solution, object or person fulfilling unrealistically many different demands; also referring sometimes to a (really existing) object, concept or person like this, for example a multi-tool or exceptionally versatile person (jack of all trades).”* Rentschler REVEN has developed such a miraculous device for air cleaning, however!
The X-CYCLONE® MO-1 is a compact mobile air cleaner with an extraction arm for oil mist, welding and laser machining fumes. The device is fitted with the following filters and separators: stage 1: stainless steel agglomeration module; stage 2: X-CYCLONE® separator; stage 3: long-life HEPA H13 filter, 30 square meters, stainless steel. The separated liquid runs down at the rear side of the device. You can find further information at: X-CYCLONE_MO_1_pictures

REVEN JAPAN – DYNEX Cooperation orders 55 air cleaners
REVEN in Japan – the company DYNEX placed the largest order of air cleaners in this year. This week, the Japanese REVEN distribution partner DYNEX ordered 55 air cleaners of the REJET-AS series, which is quite popular in Asia. The REJET-AS air cleaners are mainly used for the separation of oil mists and coolants on machining centres and machine tools, such as mills, lathes and grinding machines.

How is separation performed with the REVEN X-CYCLONE®?
Based on decades of experience in the domain of mechanical separation in ventilation technology, Rentschler REVEN has developed the mechanical separating system X-CYCLONE® in close cooperation with the industry. Air pollutants and contaminants from oil, emulsions and other fluids are largely separated from the ambient air as aerosols. The system works without any auxiliary energy or materials (such as non-woven or similar material). It is excellently suited for the separation of airborne pollutants.

Refresh your rooms overnight with the help of the ULTRA CLEANER UC-OH2!
Children need fresh air as much as healthy food. Air pollution by fungi spores, hazardous fine dust, pollen and allergens also lurks at home.
Fresh and clean air improves working conditions in offices and keeps your employees healthy. The operation of a laser printer in an office room produces particle pollution similar to that of tobacco smoke. Scientists found out that the pollution of the air in an office building (under a smoking ban) during worktime is up to five times higher than that of the outside air next to a very busy road.
