HFC-227ea Cylinder/Valve Assemblies
HFC-227ea is stored in steel cylinders as a liquid, superpressurized with nitrogen to 360 PSIG
at 70°F (25 bar gauge at 21°C). The cylinder valve assembly is equipped with a supervisory
pressure switch connection for monitoring cylinder pressure, a pressure gauge and a safety
burst disc in compliance with DOT requirements.
In addition, each cylinder/valve assembly is provided with a safety cap and a protection cap
which is a safety feature to prevent uncontrolled, accidental discharge.
Figure 3-3 through Figure 3-6 represent typical cylinder assemblies. See Table 3-4 for cylinder
dimensions.
Figure 3-3. Typical Cylinder Assembly, 10 to 70 lb.
Figure 3-4. Typical Cylinder Assembly, 125 lb and 200 lb and 300 lb Manufactured through April 2014.
WARNING
The safety cap must be installed on the discharge outlet whenever a charged
cylinder/valve assembly is not connected to the system piping. Failure to install
the safety cap could result in violent movement of the container in the event of
inadvertent actuation. Failure to follow these instructions could cause death,
personal injury and/or property damage.
