Pendent Sprinklers
Frigorificos / almacenamiento en frío?
Desafíos de Protección Contra Incendios
• Frigorificos y las instalaciones de almacenaje en frío han
sido históricamente difíciles de proteger. El potencial de
incendios desafiantes junto con un retardo de tiempo
para que el agua se descarge desde un sistema seco o
preacción
– Sistemas de rociadores en estantes son mas
propensos a daños por monta cargas y
congelamiento.
– Opciones disponibles son limitadas a sistemas de
rociadores secos o sistemas de preacción (p.e. sin
ESFR)
– Mayores costos de servicio y mantenimiento asociados a
sistemas secos y de preacción
Sistema tradicional de proteccion
almacenaje frio
Insulated
Ceiling
Crawl Space Sprinkler Piping
(heated space)
• Wet system
Ceiling Sprinkler Piping (in freezer)
• Double interlocked preaction system
Additional Requirements
• Air Supply
• Detection
• Low Point Drains
• Inspection Points for Frost Plugs
• Dry System Auxiliary Drains
All of the above require ongoing maintenance
In-Rack Sprinkler System (in freezer)
• Double interlocked preaction system
Introducing Viking’s K14 Dry ESFR
Pendent Storage Sprinklers
• Los primeros y unicos rociadores que combinan
los beneficios de supresion ESFR con la
tecnologia de los rociadores de barrill seco.
• Específicamente diseñado para proteger a los
incendios de almacenamiento de alto desafío.
Elimina la necesidad de un sistema seco y / o
de preacción , resultando en ahorros de costos
significativos.
• Permite un sistema de supresión de techo sólo
(suministrada por un sistema húmedo)
Exclusiva tecnología propia y patentada por
Viking
UL/FM Dry K 14 ESFR
Available Lengths:
18” (,457 mm)
24” (,600 mm)
30” (,762 mm)

Overview –
Viking Dry ESFR Sprinklers
• Install on wet systems only
• 14.0 (201) K factor
• Single barrel length (36 inch / 0,9 m)
• Offered with a standard 2 inch
(50 mm) grooved connection (grooved coupling not included)
• 1-1/2 inch NPT (40 mm BSP)
male thread is also available
Overview –
Viking Dry ESFR Sprinklers
• Each dry ESFR sprinkler
includes two insulating boot
assemblies, one for each side
of ceiling penetration
– Split rubber design allows for boot
to be placed around barrel after
sprinkler installation (slide up and
down barrel flat against ceiling)
– Two halves of metal cover push
together to form seal cover
– Align holes and thread fastening
screws into insulated ceiling
(fasteners are provided)

Design and Installation Criteria
• Listed and Approved to protect the
same commodities in the same
storage arrangements as a standard
K14 (201) ESFR pendent sprinkler
– Encapsulated or unencapsulated
class I, II, III & IV commodities*
– Cartoned unexpanded plastics*
– Cartoned expanded plastics*
* For Factory Mutual’s specific application & installation
requirements, refer to the latest applicable FM Loss
Prevention Data Sheets (including Data sheet 2-0 and 8-9)
Design and Installation Criteria
• Same installation criteria and obstruction
limitations as a standard K14 (201) ESFR
pendent sprinkler
– Ceilings up to 30’-0” (9,1m):
12 sprinklers @ 50 psi (3,44 Bar)
– Ceilings above 30-0” (9,1m) to 40’-0” (10,7 m):
12 sprinklers @ 75 psi (5,1 Bar)
– (4) Sprinklers must be calculated on the (3) most
hydraulically demanding sprinkler lines

System Cost Comparison

System (wet pipe)
Traditional Protection
Scheme (dry or preaction
system)
ESFR Dry Pendent Sprinklers X
Crawl Space Sprinkler System X X
Freezer Ceiling Sprinkler System X
In-Rack Sprinkler System X
Detection System X
Compressed Air System X
• These requirements could increase the installed cost of a traditional protection
scheme, compared to Viking’s dry ESFR sprinklers, by more than 50%
• FM requirements for galvanized schedule 40 pipe in the freezer ceiling sprinkler
system and in-rack sprinkler system will make the cost differential even larger
Service and Maintenance
Considerations
The simplicity of a wet pipe system also lessens the
overall service and maintenance requirements,
lowering the total lifecycle costs for facility owners
Compared to a dry or preaction system …
• No air compressor maintenance required
• No drum drip testing, inspection, and maintenance
• No detection system testing and maintenance
• No valve enclosure and low temperature alarm to inspect
• No quick opening device to test
• No auxiliary drain maintenance
• No need to keep records of trip times and full-flow tests
• No additional strainers, filters, and restricted orifices to inspect
Repair Cost
Considerations
Wet Systems:
1) Replace activated sprinkler heads
2) Clean-up damaged product
Dry and Preaction Systems:
1) Replace all sprinkler heads in system
2) Replace all broken pipe and fittings
3) Remove all system piping from freezer, thaw and reinstall
4) Replace and repair damaged detection system components
5) Inspect, repair, and test air supply system
6) Clean-up damaged product
Summary
• Viking’s dry ESFR sprinklers enable freezers
and cold storage facilities to be protected at a
significantly lower cost than in the past
• Dry ESFR sprinklers must be installed from a
wet pipe system installed in a heated space (“box-in-a-box” construction)
– Industries include food distribution, food
processing, pharmaceuticals, and storage of
certain composite materials
Summary
• Dry ESFR sprinklers provide ease of
maintenance for end users and a lower total
lifecycle cost for their fire protection systems
• Design and installation rules are the same as a
typical K14 ESFR
– Well understood by contractors, engineers, end
users, and AHJs
