DESIGN CRITERIA - ESFR COLD STORAGE SYSTEM
(Also refer to the Approval Chart on page 124 c and Design Criteria on page 124 d.)
Viking ESFR Sprinkler VK510 is also UL Listed for use with a maximum 50% by volume factory premix propylene glycol
and water antifreeze solution. This Listing is based on full-scale fire testing at Underwriter's Laboratories. The following
limitations of system design and application shall apply:
Storage Arrangements: Solid-piled, or open rack (single, double, multiple, or portable), palletized storage (pallets limited
to wood), with no open-top containers or solid shelves.
Commodity Classification: Limited to Class II or less.
Maximum Storage/Ceiling Heights and minimum pressure requirements:
•
Storage height up to 35 ft. (10,7 m) with ceiling height up to 40 ft. (12,2 m) with a minimum system design pressure of
40 PSI (278 kPa).
OR:
•
Storage height up to 40 ft. (12,2 m) with ceiling height up to 45 ft-3 in. (13,8 m) with a minimum system design pressure
of 60 PSI (414 kPa).
Maximum System Volume of the Antifreeze Water Solution: Limited to 1,100 gallons (4 163 liters).
Minimum Temperature: -21 °F (-29.4 °C).
Maximum Percentage by Volume of Propylene Glycol: 50% mixed with water for antifreeze solution.
•
Where the minimum temperature in the area being protected is 8 °F (-13.3 °C) or above, 35% percent by vol-
ume of propylene glycol factory premixed with water must be used. Viking requires Firefighter Eliminator C
premix 35% propylene glycol/water mixture with a freeze temperature rating (freeze point) of 2.4 °F (-16.4 °C).
OR:
•
Where the minimum temperature in the area being protected is between 8 °F (-13.3 °C) and -21 °F (-29.4 °C), the
percentage by volume of propylene glycol must be 50%, factory premixed with water for antifreeze solution. Viking
requires Firefighter Eliminator F type 50% propylene glycol/water mixture, with a freeze temperature rating (freeze point)
of -26 °F (-32.2 °C).
