Viking Introduces the Next Generation Freedom® Residential Concealed Pendent Sprinkler

Tuesday, December 20, 2016 - 3pm

FOR IMMEDIATE RELEASE                                                                                                                                                                               

Hastings, Michigan, USA – The Viking Corporation, a global leader in fire protection and life safety systems, announces the availability of its new Freedom® residential flat plate concealed pendent sprinkler (Model VK494).  Leveraging new “Ultra-Fast” glass bulb technology, the new 4.9 K-factor concealed sprinkler represents a significant advancement in residential fire protection. 

The new VK494 is UL Listed at the minimum flow rates for 16 x 16’, 18 x 18’, and 20 x 20’ coverage areas in both a 155°F (ordinary) and 200°F (intermediate) temperature rating.  It is the first residential concealed sprinkler with the same flow rates for both ordinary and intermediate temperature- ratings.  As a result, residential sprinkler installers can now standardize on an intermediate temperature-rated sprinkler, without having to sacrifice either performance or aesthetics.

While ordinary temperature-rated sprinklers, with an operating range between 135°F and 170°F, can only be used when ambient temperatures are below 101°F, intermediate temperature-rated sprinklers (175-225°F) can be installed in environments up to 150°F.  Standardizing on intermediate temperature sprinklers offers several benefits including greater installation flexibility around potential heat sources such as fireplaces, heat diffusers, skylights, and ovens, as well as reduced inventory complexity and less confusion at the job site. 

The new Model VK494 sprinkler is available with three cover plate styles (standard diameter, large diameter, and square) and uses the same installation wrenches as Viking’s Mirage® commercial concealed pendent sprinkler.
