Improved Air Cooler | CAL3K Features

The new Air Cooler replaces the traditional (but very fast and expensive) water cooler. It also uses less resources (electricity & water). The air cooler works best when the vessel temperature is well above the ambient temperature. This is possible because the CAL3K vessel, with linear temperature sensing, allows higher vessel temperatures. The air cooler can cool a vessel in 6-7 minutes from 44°C to 32°C when the ambient (room) temperature is at 25C.

This feature applies to the following CAL3K Systems : CAL3K-AP , CAL3K-A , CAL3K-U , CAL3K-F


The cooler is the slowest system component. We have optimised it as best we can; but it is slow! It cools a vessel down by blowing air at it. Not a very efficient way, BUT very resource friendly and economical.

Room temperature control is not required. The CAL3K can work in any environment suitable for humans. Consult the factory if you like to operate the CAL3K below or around 0°C.

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).
