REVEX ® -EH-WTechnical data – Induction hoodwith condensation separation and autom. separator cleaning / wall-mounted versionSystem description2.1. Type REVEX ® -EH-W + EH-NThe hood is made of a durable stainless steel structurewith welded corner joints. All cutting edges are envelopedand rounded free from burrs.The hood is equipped with grease- and waterproof exhaustsegments made of stainless steel. The grease separatorsare inserted in a slanted position into these segments inaccordance with VDI 2052. The hood canopy is suitablydesigned to retain even surge vapours. The special lightfixtures, type EB with polycarbonate cover, are splash andjet waterproof, with IP 54 protection and heat resistanceup to 110 °C. The polycarbonate cover offers highest transparencyand is breakproof and resistant to impact, oil andacid at the same time. The light fixtures are fully wired upto the connection box. The grease drain cock with internalthread is located in the deep-drawn drain area of thegrease collecting channel. The exhaust air chamber canaccommodate various types of grease separators that canbe inserted without tools. The hood is placed above thekitchen equipment block and should project sufficiently overthe outer edges of the appliances. A spraying facilityfor warm water is integrated in the exhaust air chamberand provides for the cleaning of the grease separators onboth sides at regular intervals. The control system includedin the washing facility allows the adjustment of the cleaningintervals to the actual level of contamination of the separators,which depends on the kitchen equipment used. In order tointensify the cleaning process, a grease remover is injectedduring the main washing cycle.The monitoring and automatic control of the self-cleaningextraction hood REVEX ® is ensured by a modular, freelyprogrammable process controller that offers variousadjustment options. Among other things, you can set alldesired values, such as the start time of the sprayingcycle, the spraying time, the injection time of the cleaningagent as well as the rinsing time. The maintenance intervalsare also indicated by the controller. The solenoidvalves that control the cleaning units are located on topof the hood roof. They are completely wired and pipedand are ready for connection to the on-site water supply.The strainer and the pipe network insulating valve are tobe delivered by customer.The hood is fitted with a patented Venturi supply airnozzle that can handle unheated fresh air of up to 20to 70 % of the exhaust air volume. The round nozzleblows inducing air into the hood. This airflow picks upthe pollutant particles from the rising cooking vapoursand transports them to the aerosol separators wherethey are captured immediately. In pure exhaust airhoods without induction, the thermal airflow containingthe pollutants is not immediately captured by the aerosolseparators because the suction effect is relatively low.The contaminated air mixes to a very high extentwith the ambient room air and produces an undefinedinduction! REVEN ® induction hoods completely preventany negative undefined induction because they transportthe pollutant particles directly to the separatorsvia the inducing airflow (push & pull principle). Anotherpositive effect is the additional condensation separationthat is due to the temperature difference between theinducing airflow and the rising thermal airflow. Whenusing REVEN ® induction hoods with condensationseparation you can easily comply with the minimumair exchange rate of 90 m 3 /h per m 2 kitchen surfacerequired by VDI 2052. In many kitchens, the exchangerate still falls considerably below this limit.The stainless steel structure of the hood is fitted witha thermal insulation for temperatures down to -50 °C inthe supply air area.The hood and its components are TÜV-tested in accordancewith VDE and UL regulations. A hygiene report is availabletoo. All versions of this hood comply with regulation VDI2052 issued by the Association of German Engineers andthe workplace health and safety regulation BGR 111 issuedby German Trade Associations.Material: chromium nickel steel(material no. 1.4301)Surface finish: fine sanding, 180 grainincl. protective film35
