Product Manual - Perma-Cyl
®
w/ FlexFill™ Piping Option
General
The Perma-Cyl
®
MicroBulk Storage System w/ FlexFill
™
Piping Option is designed to store and deliver liquid
oxygen, nitrogen or argon as a cryogenic liquid or gas.
The Perma-Cyl tank can build and maintain pressure from
the automatically regulated pressure building circuit.
A continuous gas ow is provided from the cylinders.
Regardless of size, all Perma-Cyl tank models operate on the
same principals of operation.
Caution! Only use replacement equipment,
which is compatible with liquid
oxygen and has been cleaned
for oxygen use. Do not use
regulators, ttings, hoses, etc.,
which have been previously used
in compressed air. Failure to
comply with these instructions
may result in serious damage to
the system and personal injury.
Initial Inspection
Receiving inspection is one of the most important operations
in the life of the tank and should be done thoroughly and
conscientiously so as to nd any possible indications of
damage and prevent expensive surprises during the rst
use of the vessel at the site. Upon receipt of a Perma-Cyl
tank, remove the protective wrapping and inspect for the
following:
• Any shipping damage including dents, cuts, broken and
bent plumbing components. Report any ndings to the
shipping company immediately.
• Examine welded and brazed joints on plumbing for
cracks or deformation, especially on valves and ttings.
• Check burst discs and relief valves for dirt/damage.
• Check to ensure there is positive pressure on the inner
vessel, normally about 20-25 psig. Tanks are shipped
with NF purity nitrogen gas. Purging is necessary prior to
lling.
• If the tank passes all the above criteria, it is ready for
rst ll. Follow the rst ll procedures in the Installation
portion of this manual.
Note: The PC5500 is the only Perma-Cyl
tank that is equipped with a vacuum
thermocouple.
• On the 5500 Perma-Cyl tanks check the insulation space
pressure with a suitable thermocouple vacuum gauge
(follow procedure below). Make a note of the ambient
temperature when the vacuum is read. Temperature
changes affect the vacuum reading in a warm empty
vessel.
– If warm vacuum is above 20 microns, consult factory.
Vacuum Check Procedure - Perma-Cyl
5500 Only
The standard Chart vacuum probe is a Teledyne-Hastings
DV-6R probe. Select a compatible instrument to read the
output of the vacuum probe.
Caution! Unauthorized changing of the
vacuum probe will void vessel
warranty.
1. Remove rubber cap on probe outlet to expose contact.
Note that the probe housing need not be opened to do
this.
2. Plug the instrument in to the probe and calibrate the
instrument.
3. Open the vacuum probe isolation valve. Wait for ve
minutes and take vacuum reading. Note that valve
handle protrudes through protective housing and can be
turned without opening the housing.
4. Close the isolation valve and take a second reading.
Monitor the rate of rise in vacuum probe with isolation
valve closed. If the vacuum continues to rise at a
constant rate, it is possible that the probe assembly is
leaking. Consult the factory.
5. Verify that the isolation valve is closed.
6. Replace the rubber probe cap.
7. Compare the vacuum reading obtained now to the
reading taken prior to shipping.
