Bomb Calorimetry is a procedure which determines the heat of combustion or calorific value of solid and liquid materials which are burned as fuels. It is a primary test of great importance to the following industries : coal production, power stations, fuel analysis, animal feed research, educational institutes, commercial analytical laboratories, by-product analysis, building materials, etc.

Digital Data Systems (Pty) Ltd specializes in the design and manufacture of scientific Bomb Calorimeter Systems for various types of industries and applications from the coal mining industry to educational institutes. DDS Bomb calorimeter Systems are the most advanced bomb calorimeter systems available today. The system is used to measure the calorific value of both solids and liquids. DDS has three different Bomb Calorimeter models in the CAL2K Scientific Range.
Our entry level system, the ECO Bomb Calorimeter has an operator test time of 5 minutes per sample, with a removable screw cap vessel, semi-automatic oxygen filling, and can handle 1 sample per hour with 2 bomb vessel. This system is ideal for educational purposes in universities and laboratories that don't require the large quantity of sample throughput.
Samples Per Hour
Our intermediate system is the E2K Calorimeter System, with a screw cap removable vessel, semi-automatic oxygen filling and can handle 6 samples per hour using 2 bomb vessels. This option allows more samples per hour and allows the operator to print results directly to a printer.
Samples Per Hour
The CAL2K is the top of the range when it comes to CAL2K Calorimeters. This system allows up to 10 samples per hour using 2 vessels, and stores up to 2000 results in it's memory. The operating time per test is approximately 2 minutes, making it fast and accurate.
Samples Per Hour
The DDS CAL2K range is used to determine the calorific values of liquid and solid sampled. The range of CAL2K oxygen bomb calorimeters is manufactured to be used with various applications; coal analysis and oil analysis being the most popular applications.
The CAL2K range consists of the entry-level system (The ECO Calorimeter), which delivers up to 1 sample per hour, the mid-level system (The E2K Calorimeter), which delivers up to 6 samples per hour, and the advanced system (The CAL2K Calorimeter), which delivers up to 10 samples per hour.
The E2K and CAL2K deliver more samples per hour, making the system cost-effective (compared to other systems), fast and reliable, with maximum productivity.
The CAL2K calorimeters are easy to set up, with easy to remove connections, making the systems compact, lightweight and easy to move.
The CAL2K can be applied in the coal, petrochemical, medical research, cement, power generation and animal feed research industries. Other applications include : oil, coke, coal, foodstuff and biomass products applied in power plants, coal mines, metallurgy, chemical industry, commercial inspection, scientific research, etc.
When a determination/sample analysis is started the calorimeter will automatically run through the initial, firing and final stages without any operator action required, and can record and save the test data automatically to the calorimeter/vessel.
All our bomb calorimeter are supplied with one or more CAL2K-4 bomb vessels and the required installation kits (includes firing cotton, firing wire, benzoic acid tablets, consumables, etc.). The complete system also includes a filling station which is used to fill the vessel with oxygen and/or a water cooler to cool the vessel after a determination.
The use of multiple bomb vessels minimizes the down-time by preparing the second bomb and sample while the current sample is being analyzed.
The CAL2K range of oxygen bomb calorimeters comprises of : a manual filling station, a waterless system with external water cooler, Windows compatible software, printer connection, balance connection and LIMS support. DDS oxygen calorimeters offer high performance and low maintenance at a competitive price.
The CAL2K range makes it possible to achieve a 2-5 minute operator time per test without compromising its accuracy or precision.
External Cooling System - (CAL2K water cooler, only used with CAL2K & E2K oxygen bomb calorimeters) After numerous determinations/sample analysis the vessel temperature rises and needs to be cooled for the next sample analysis. The external water cooler ensures that the vessel temperature is lowered or cooled to ambient temperature to minimize the influence.
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.
Bomb calorimeters are designed and manufactured to endure and sustain large pressure inside the calorimeter chamber as the reaction has to be measured simultaneously. The sample is ignited with electrical energy during the firing process. During this process the vessel is heated from the combustion process.
A bomb calorimeter basically consists of a cup (crucible) to hold the sample, oxygen, a stainless steel bomb vessel, the insulating container (to prevent heat flow from the calorimeter to the surroundings; the polystyrene acts as the insulating container in the CAL2K), water (the CAL2K range is waterless), and an ignition system connected to the bomb for igniting the sample.
The CAL2K range features a micro-processor based bomb vessel with automatic measurements of the calorific value of the sample, a clear LCD display, printer connection, connection to a standard keyboard, user interaction prompts on screen, memory storage for data, real time clock, PC software for recording data, and full LIMS integration.
