| New quick response sprinkler  Viking Corporation has extended its leading Mirage line of commercial concealed sprinklers to include an 11.2 (161) K-Factor, Extra-Large Orifice (ELO) sprinkler. This new quick response sprinkler, model VK469, is specifically designed for applications requiring both a higher water density and the appearance of a flat-plate concealed sprinkler. This includes applications such as casinos, exhibition halls, hotel lobbies, airport terminals, places of worship, and certain retail environments. The new Mirage ELO sprinkler is cULus listed for up to and including Ordinary Hazard Group II occupancies. It has a 74°C temperature rating and features a flat cover plate with 13 mm of vertical adjustment. The sprinkler's cover plate is available in four standard finishes and a nearly unlimited variety of custom finishes. The new sprinkler's extra-large orifice allows for higher water densities to be applied even when limited water pressure is available. The VK469 may also eliminate the need for a fire pump, or reduce the size of the pump if required. On existing systems, replacing large orifice sprinklers with the new Mirage ELO may provide the higher densities needed to increase the occupancy's hazard classification. write your comments about the article :: © 2009 Construction News :: home page |
