Air cooler CAL3K-2

The new Air Cooler replaces the traditional expensive water cooler used with the CAL3K range of calorimeters. It uses less resources, including no water and less electricity, to operate. The air cooler works with the ambient air to cool the vessel down, ready for the next determination. Best of all, the air cooler is extremely fast, affordable and efficient. This is possible because of the CAL3K vessel, with linear temperature sensing, allowing higher vessel temperatures. The air cooler can cool a vessel in approximately 6 to 8 minutes to its set target of 9°C above ambient temperature. In other words, in a laboratory with 25°C ambient temperature a warm vessel of 44°C is cooled to 34°C in 8 minutes. The power consumption of the cooler is extremely low and efficient making for an environmentally friendly and space conscious solution. To speed up the cooling, an affordable second cooler can be used. The cooling process takes the longest time, so simply connect two coolers together to halve the cooling time in a multi vessel calorimeter system. 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. In difference to the older CAL2K Cooler: The air cooler is slower than the CAL3K. This can be compensated by the purchase of more coolers.
