Air cooler / laboratory

The new Air Cooler replaces the traditional (but very fast and expensive) water cooler used with the CAL2K range of calorimeters. It uses less resources, including water and electricity, to operate. The air cooler works best when the vessel is above the ambient temperature.

This is possible because of the CAL3K bayonet vessel, with linear temperature sensing, allowing higher vessel temperatures. The air cooler can cool a vessel in approximately 6 minutes from 14°C to 4°C above ambient temperature. In other words, in a laboratory with 25°C ambient temperature a warm vessel of 39°C is cooled to 29°C in 6 minutes.

The air cooler is what is says. It needs no water, piping or other resources. However, it has a much more defined operating characteristic - it does not work at room temperature or below. Or, in other words : it works best when the vessel is warmer than the ambient temperature (room temperature).

Because of this, the vessel temperature cycles between 38-48°C in a production environment, and between 28-38°C for slower users. The air cooler has some intelligence built into it, and indicates the bomb temperature and when the vessel is ready to remove.

The cooling performance depends on the ambient temperature. The temperature rise of 0.5g Benzoic Acid is approximately 10°C. If one assumes an ambient temperature of 25°C and a cooling time of 6 minutes, then the cooler will operate between 35-45°C. This works well with the determination speed of the machine. With three bombs and two coolers a fast timing is possible.
