NOTE: With some applications you may need to fill the Vessel to less than 3000KPA e.g.
•
1500KPA (15 bar), however this is only applicable when you have a sample which is highly
combustible, for example with wood related samples.
REMEMBER: You may fill the Vessel LESS than 3000KPA but NEVER more than 3000KPA.
•
5.2.1 HIGH PRESSURE OXYGEN
The type of Oxygen to be used is the standard Industrial Oxygen used for welding. A purity
•
of 99.5% will be suitable.
Conform to the industry standard of handling procedures for oxygen bottles.
•
Secure the bottle against a wall.
•
Should the Oxygen supply be in another room, make sure there is a high pressure shut off
•
valve near the 3K-3 Filling Station installation.
5.3
VESSEL (4K-4)
• Handle the vessel over a table or solid surface.
• Do not drop a vessel.
• Do not overfill a vessel with oxygen: The maximum oxygen filling pressure is 30bar / 3000kPA, which
is the standard for bomb calorimetry.
• Use the provided De-filler cap only, part number: 3K-3-22.
• Do not use any oil or grease on any of the oxygen fittings or the O-rings. A very small amount of
high-pressure (vacuum) grease is allowed on the O-ring to make them pliable. Wipe them clean
afterwards.
• Store the vessel with the lid open. Never store a vessel under pressure, always deflate using the de-
filler cap.
• Clean the inside of the vessel with paper towel after every use.
• Weigh the crucible every week and discard it when it has lost 10% of its original mass.
• Discard the crucible when the bottom is distorted and extremely discoloured.
• Remove the deflector plate every week and clean the top surface. It does accumulate residue and
must be clean regularly.
• Make sure to use the pipe-clamping device on the right side of the filing station for safe use.
NEVER OPERATE ANY UNSAFE VESSEL.
•
NEVER IMMERSE THE VESSEL INTO COLD WATER WHEN COOLING. ALLOW THE VESSEL
•
TO COOL DOWN NATURALLY.
A SUITABLE INSPECTION WARNING PERIOD OF 2000 FIRINGS, AND A STOP OPERATING LIMIT OF
•
2500 FIRINGS ARE PRE-PROGRAMMED FROM THE FACTORY
