12.0 ANTIFREEZE SOLUTION 50%
12.1 Description
Viking Firefighter Eliminator F is a certified premixed 50% propylene glycol/water
antifreeze solution required for use with the Viking ESFR Cold Storage System.
The system provides fixed fire protection for refrigerated or cold warehouse
storage and is also appropriate for unheated storage applications in areas
subject to freezing, to a minimum temperature of -21 °F (-29.4 °C). The piping
system is filled with pressurized propylene glycol and water solution maintained
from a pressure pump system that controls and maintains the desired solution
pressure. This is a pre-primed preaction system with electric release that utilizes
a deluge valve with conventional and electric release trims. The riser consists of
two Viking Easy Riser
TM
Swing Check Valves, one with special cold trim and the
second with by-pass trim to isolate the antifreeze in the system from the water
supply.
