Laquer drying cabinets and Ex- proofed heating cabinets Brochure

HORO Dr. Hofm ann GmbHLaquer drying cabinets and Ex- proofed heating cabinetsExplosives need spezial care, because for an explosion you need threethings: — a concentration of explosives as gas, fog, vapour or dust— some oxygen, as in the air— a source of ignition Hot surfaces, electrostatic charging, sparks, mechanical strokes or friction are amongothers such sources of ignition. So there are many sources of ignition in a heatingcabinet and these need to be considered and modified to avoid any dangerous situation.We look for solutions to have a safe operation of the heating and drying cabinets.Laquer drying cabinets according to EN 1539 / BGV D 24 are suitable to work with smallamounts of explosive vapour and gases. The primary explosion protection used islimiting the concentration of the explosive vapour and gases.EX- proofed heating cabinets are needed in case larger amounts of explosive vapour andgases are present or if the cabinet is placed in an atmosphere related to zone 1 or zone2. We have the following basic types:— EX- proofed working volume inside of the heating cabinet installed in a harmlessambient.— Installation inside EX- zone 2 or EX- zone 1 with the electronic control outside ofEX- zone 2. This is an economic version which does not need any additionalmeasures for the switch cabinet outside. The EX- protection is only needed for thecomponents of the heating cabinet.— Installation inside EX- zone 2 or EX- zone 1 with integrated control as a compactversion or if the area of EX- Zone 2 is extensive. 627 AL-EX 4256 ALL-BGL 200 AL-IEX Tell us your needs and we will discuss with you the situation and make an suitableproposal for the optimal usage.
