2.6.2 CONTAINER LOCATION(S)
The type and location(s) of the storage container(s) is based on several considerations.
1) Agent Quantity – The agent storage container(s) selected must have the capacity to store the total
quantity of agent required for the system.
2) System Type – An area might be protected by several smaller containers with independent nozzles,
or it might be protected by a large capacity container that is discharged through a piping network of
2, 4, or more nozzles.
3) Extent of Piping – In systems having an unusually large piping system, the pressure drop may be
too great for the location or configuration selected. In some cases, it may be necessary to relocate
the container(s) closer to the hazard area(s) being protected. It may also be necessary to sub-
divide the piping network into smaller configurations with separate containers.
4) Floor Space – Consideration should be given to the space available to install the container. For
example, a 1,300 lb. (590 kg) system could be stored in (2) 650 lb. (295 kg) containers located on
the floor. However, if floor space is a problem, the system could be designed to utilize (6) 215 lb.
(97.5 kg) Inverted Containers mounted on the wall(s).
5) Cost Factors – In the example above, the (2) 650 lb. (295 kg) containers would be less expensive
than the (6) 215 lb. (97.5 kg) containers.
6) Serviceability – In general, the larger the container, the more difficult it will be to remove it from the
system for maintenance and service. However, smaller containers that are located in a subfloor
space, under a computer bank, or above the ceiling over the same computer bank, can be difficult
as well.
7) Floor Loading – This factor must be considered when selecting a container location. Excessive
floor loading may require relocating the container(s) to a more suitable location.
8) Proximity – HFC-227ea Containers should be located as close as possible to, or within the
hazard(s) that they protect.
9) Environmental Effects – Do not locate containers where they would be subject to physical damage,
exposure to corrosive chemicals, or harsh weather conditions
2.6.3 STORAGE TEMPERATURE LIMITATIONS
Fike HFC-227ea systems are UL Listed and FM approved for a service temperature range of +32
o
F to +130
o
F
(0
o
F to 54
o
C). However, the system designer should be aware that the computer flow program for Engineered
Systems is based on an ambient temperature of 70
o
F (21
o
C). Therefore, the container storage temperature range
for an Engineered System must be in the 60
o
F to 80
o
F (16
o
C to 27
o
C) range. At temperatures outside of this
range, the system may not supply the desired quantity of agent.
NOTE: Pre-Engineered Systems have been pre-tested and verified for the full operating range of +32
o
F to +
130
o
F (0
o
F to 54
o
C).
