Technical data

12.3 Features

• Has a freeze temperature rating (freeze point) of -26 °F (-32.2 °C). (Note:

Freeze temperature is where ice crystals begin to form.)

• Is a ready-to-use solution pre-mixed in the proper 50% propylene glycol

concentration for the Viking ESFR Cold Storage System, in areas subject to

freezing, to a minimum temperature of -21 °F (-29.4 °C).

• Was utilized in the full-scale research fire tests for the Viking ESFR Cold

Storage System.

• Includes corrosion inhibitors to provide corrosion control and microbiological

control of the system piping and components.

13.0 ANTIFREEZE SOLUTION 35%

13.1 Description

Viking Firefighter Eliminator C is a certified premixed 35% propylene glycol and

water antifreeze solution required for use with the Viking ESFR Cold Storage

System for use in applications having a minimum temperature as low as 8 °F (-

13.3 °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

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.
