These are used to retain the fumes, dust, oils from the extraction hoods, to clean them and release them to the atmosphere. This will ensure that no inconvenience will be caused to the public. Wet flushing cabinets may be manufactured as an individual component and mounted on the ready extractor system and also be manufactured as an integrated component of the extractor system package. The nozzle system flushes the polluted air. The drift eliminator in the system prevents the flushed air from carrying water. The flushing cabinet is made of 1,5 mm stainless sheet. Since the wet flushing cabinet has a welded design, it is also sealed off. This system consists of a metallic filter, a water pump, nozzle, drift eliminator and discharge valve. Nozzles: The surface is made of polypropylene and features 6, 8 or 10 mm holes. The specified diameters prevent blockages in the nozzles. The tips of the nozzles are made of stainless steel. These can be easily replaced, installed or demounted. The nozzles are designed for the installation of pipes that are 40 mm in diameter. To achieve the intended relative humidity, the pressure levels of the nozzles must be P=1,5-2,8 bars. During the cleaning process, the interior apparatus and nozzles can be easily removed and hygienically cleaned. Circulation Pump: Creates an adequate pressure at the nozzle inlet and circulates the water. The pumps can be used as mono-blocks or single pipes depending on the parameters. For saving power and better adjusting the humidity, a frequency converter (inverter) is used. A better adjustment can be achieved by maintaining the pressure between P=0,3-2,8 bars.
