Section 3 Fill Components
3.4 Valve Closing Adapter
P/N 17292 (See Figure 3.4)
e valve closing adapter is threaded onto the valve actuation connection of
the cylinder valve and receives pressure from the nitrogen supply at the end of
the filling procedure to close the cylinder valve. A 1/4 inch (8 mm) male quick-
connect fitting (P/N 99499) is installed in the 1/4 inch (8 mm) FNPT inlet
port of the valve closing adapter and is utilized to facilitate connection to the
valve closing line of the nitrogen regulator-hose assembly.
3.5 Agent Supply Tank
Novec 1230 fluid is supplied in drums of 661 lb (300 kg) capacity or IBC containers of 2425 lb (1100 kg)
capacity.
3.5.1 IBC Container
Because Novec 1230 fluid is a liquid at typical ambient temperatures and pressure, pumping agent from
an IBC container in a closed system can create a vacuum detrimental to the structural integrity of the
IBC container. To counter this effect, a dry nitrogen supply is regulated into a port at the top of the IBC
container at approximately 5 psig (0.35 bar). Refer to 3M™ Novec™ 1230 Fire Protection Fluid Storage
and Handling document 60-5002-0131-8 for additional information.
3.5.1.1 IBC Coupler Kit
P/N 99501 (See Figure 3.5.1.1)
e IBC coupler kit is utilized to connect a dry nitrogen supply to the
top port of the IBC container during the agent fill procedure. e top
port of IBC container ships fitted with a check valve that upsets when
the coupler kit is installed to it. e coupler fill head is a quick connect
fitting that is attached to the top port valve and turned clockwise 1/4
turn to lock into place. e coupler supply connection is a 1 in (25 mm)
MNPT connection fitted to a nitrogen coupler hose line that attaches to
the outlet of the low pressure nitrogen regulator. e coupler kit controls
the flow of nitrogen into the IBC container through a manually actuated
piston valve. It is fitted with a pressure relief valve set at 10 psi (0.70
bar). Refer to 3M™ Novec™ 1230 Fire Protection Fluid Storage and
Handling document 60-5002-0131-8 for additional information.
3.5.1.2 Low Pressure Nitrogen Regulator
P/N 99951 (See Figure 3.5.1.2)
A low pressure nitrogen regulator is installed in the nitrogen vapor line between the nitrogen supply and
IBC coupler. It regulates the nitrogen pressure entering the IBC container down to approximately 5 psig
(0.35 bar). e inlet port is a CGA 580 fitting. Refer to 3M™ Novec™ 1230 Fire Protection Fluid Storage
and Handling document 60-5002-0131-8 for additional information.
