How to cool the CAL3K Oxygen Bomb Vessel

How to cool the CAL3K Bayonet Bomb Vessel | DDS Calorimeters


After running a sample, once the determination is complete, the CAL3K Oxygen Bomb Vessel can be removed from the calorimeter. Before de-filling or preparing the bomb for the next firing it needs to be cooled – this is done using the CAL3K Air Cooler (supplied with most of our calorimeter systems).

To start the cooling process, remove the bomb vessel from the calorimeter, make sure the air cooler is powered up, and placed the warm bomb vessel into the air cooler. The air cooler will automatically start cooling the vessel with air. Once the air cooler prompts that the vessel is “Ready for use” the bomb vessel can be removed, de-filled, opened and inspected before the next determination.

Multiple air coolers can be included in the system for faster throughput. NEVER submerge the CAL3K Bomb Vessel into water to cool – always make use of the supplied air cooler or allow the vessel to cool to room temperature naturally.

  • The air cooler works with the ambient air to cool the vessel down for the next determination.
  • The air cooler can cool a vessel in approximately 6 minutes.
  • It has a small footprint – with a reduced carbon footprint as no water is required.
  • Reduced noise makes the operation of the air cooler near silent.
  • The air cooler prompts the user, indicating when the vessel is ready to use.


  • After the determination is complete in the calorimeter, remove the vessel and place it inside the air cooler (the cooler should be powered up).
  • The air cooler will now run through the cooling process and check the temperature of the vessel.
  • The air cooler will prompt the user when the vessel is ready to be removed and to be used for the next determination.
  • During the cooling process the air cooler will show the serial number, amount of firings and temperature of the inserted vessel.
