Thursday, May 31, 2012


Hastings, Michigan, USA - Viking Corporation, a global leader in fire protection and life safety systems, announces the availability of a new quick response, extended coverage, horizontal sidewall sprinkler designed specifically to protect corridors, hallways, decks, walkways, and any other application where a wide spray pattern is optimal. The new model VK638, which is cULus Listed for Light Hazard occupancies and has a K Factor of 8.0 (115), is available in both recessed and domed concealed models.

The new “Corridor Sprinkler” uses Viking’s patented flow-shaper technology to provide larger coverage areas at lower flow and pressure requirements. The VK638 is cULus Listed for 28 x 12 ft (8,5 x 3,7 m) and 28 x 14 ft (8,5 x 4,3 m) coverage areas, with the deflector installed up to 12 in (305 mm) below the ceiling. The 28 x 12 ft (8,5 x 3,7 m) coverage area is unique in the industry, providing a significant flow and pressure advantage for fire sprinkler systems where this area of coverage can be applied.

Both the recessed and domed concealed models are available in 135°F (57°C), 155°F (68°C), 175°F (79°C), and 200°F (93°C) temperature ratings.
