The DDS CAL3K range is used to determine the calorific values of liquid and solid samples. The range of CAL3K oxygen bomb calorimeters is manufactured with various applications in mind; coal analysis and oil analysis being the most popular applications. The latest addition to the DDS Scientific range is the CAL3K-U bomb calorimeter, which is optimized for university use and educational institutions. The CAL3K-AP Oxygen Bomb Calorimeter combined the isothermal and adiabatic methods in one system. We call this new method dynamic. DDS has been designing and manufacturing high precision oxygen bomb calorimeters for over 30 years. The DDS Calorimeters are easy to set up, with easy removable connections, making the system compact, lightweight and easy to move.
The calorific value of any solid or liquid material that can be safely burned in any oxygen bomb can be fired using a CAL3K machine. All our bomb calorimeters are supplied with one or more bomb vessel (s) and the required installation kits (firing cotton, firing wire, benzoic acid tablets, consumables, etc.) The complete CAL3K-AP system also includes the air cooler to cool the vessel after a determination. The CAL3K range of oxygen bomb calorimeters simproses of : a CAL3K calorimeter ( CAL3K-AP , CAL3K-A , or CAL3K-U ), filling station (excludes CAL3K-AP ), a waterless external air cooler , Windows based software , printer connection, balance connection and LIMS integration. DDS oxygen bomb calorimeters offer high performance and low maintenance at a competitive and affordable price.
The CAL3K can be applied in the coal, petrochemical, medical research, cement, power generation and animal feed research industries. The CAL3K can also be used to analyze coal, coke, oil, foodstuff and biomass products and is applied in power plants, coal mines, metallurgy, the chemical industry, for commercial inspection and scientific research. The use of multiple bomb vessels minimizes the waiting period by preparing the second bomb with a sample while the current sample is being analyzed. Up to 10 bomb vessels can be prepared and used in the CAL3K-AP system with routine sample determination. We recommend 2 bomb vessels per system.
The CAL3K-AP is the first in the range of Oxygen Bomb Calorimeters from DDS, and features automatic oxygen filling and automatic temperature control (ATC). It is best suited for a clean and well maintained laboratory with a requirement for very fast and accurate results. The CAL3K-AP Calorimeter can perform up to 12 samples per hour using 3 CAL3K Oxygen Bayonet Bomb Vessels.
The CAL3K-A is the second in the range of Oxygen Bomb Calorimeters from DDS, and features an external oxygen filling station with manual filling. It is best suited for a production environment with shared oxygen supply (to other users) and robust handling. The CAL3K-A Calorimeter can perform up to 12 samples per hour using 3 CAL3K Oxygen Bayonet Bomb Vessels.
The CAL3K-U is the third in the range of Oxygen Bomb Calorimeters from DDS, and features an external oxygen filling station with manual filling. It is best suited for universities, educational institutions and robust handling. The CAL3K-U Calorimeter can perform up to 9 samples per hour using 3 CAL3K Oxygen Bayonet Bomb Vessels.
The CAL3K range makes is possible to achieve a 5-6 minute operator time per test without compromising its accuracy or precision. After numerous determinations/sample analysis the vessel temperature rises and needs to be cooled for the next sample analysis. The external air cooler ensures that the vessel temperature is cooled to firing temperature in preparation for the next firing.
Convenient Waterless System - The oxygen calorimeter is operated without water. No measuring, spilling or leaking. The calorimeter is ready to use without needing to fill it with water, reducing sample preparation time. The new air cooler also operates with out water. The entire CAL3K calorimeter system requires no water making it environmentally friendly.
Our CAL3K bomb calorimeters are designed to endure and sustain large pressure increases inside the calorimeter combustion chamber. The bomb vessel is pressurized with 30Bar of pure oxygen in the initial period of the determination. The sample is then ignited in the firing period with electrical energy. During the main period the vessel is heated from the combustion of the sample. The pressure of the vessel rapidly increases with relation to the type of sample being burnt.
A bomb calorimeter basically consists of a cup (crucible) to hold the sample, deflector plate, oxygen, a stainless steel bomb vessel , the insulating aluminium sleeve, the electronic controller card and theignition system connected to the outside of the bomb for igniting the sample.
One of the CAL3K-AP features is a micro-processor in the base of the bomb vessel for the automatic measurement of the calorific value of the sample. This unique design ensures no energy is loss or gained in the determination cycle, increasing the repeatable accuracy of the bomb vessel . The on-screen subject help is great way to have subject help at every step of the calorimeter operation.
