CAL3K Air Cooler
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 new air cooler takes a step towards a greener future.
Using less resources, including electricity and water, to reduce your carbon footprint.
CAL3K AIR COOLER
The new Air Cooler replaces the traditional expensive water cooler used with the CAL2K 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 and efficient and affordable.
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 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.
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.

Animal Feed Research
Food calories are measured in KJ/g, the same as combustible calories. However, the process is different, although the outcome is the same : KJ/g or heat, or calories. Animal feed stock relies on the animal digestion (conversion). A calorimeter burns the lot and measures the released heat. Then a calorimeter can't be used to measure feed stock?
View ApplicationCoal & Coke Analysis
The coal industry is the traditional application of calorimeters because coal has a variety of properties, apart from being black. If the coal is used for steam generation then the calorific value is of paramount importance. The calorific value, short CV, is a measure of how much heat can be extracted from it.
View ApplicationExplosives Analysis
Only explosives which can be ignited by heat from the calorimeter's firing circuit can be tested in the oxygen calorimeter. Then very minute/small quantities are used for analysis. The calorific value of an explosive is not very high, but the burning speed is.
View ApplicationFuel Analysis
As a general rule, volatile fuels are measured very seldom because they are very consistent. However, if the fuel absorbs water, then frequent analysis is called for. Volatile fuel such as alcohol must be prevented from evaporating during the handling process that is from weighing to ignition of the sample.
View ApplicationFood & Nutrition Analysis
Here is an example of food calories from www.scientificamerican.com. As the article says : "The method of using a combustion calorimeter to measure food calories is not frequently used today. However, after some considerations it can, and is, used today for checking the production quality of food." Let's look at the details.
View ApplicationOil Analysis
Oils are a non-volatile substance. In general they are not measured frequently because they are very consistent and uniform. Other oil properties are more important than the calorific value, such as taste or viscosity. If an oil is measured in an oxygen calorimeter, then the procedure would be the same as a solid substance.

Heating energy is being dumped on our municipal landfill sites. Our landfill sites are being clogged by plastic waste, which battle to bio-degrade over time. Alternative options for managing plastic waste has been identified as mechanical recycling, cement kilns, power station and energy recovery by incineration.
