CAL3K-A Oxygen Bomb Calorimeter System
The CAL3K-A is the companion to the CAL3K-AP, but with external oxygen filling. This instrument was designed for rough production environments where the automatic filling is not desired.
APPLICATION : The CAL3K-A uses a combination of the Isothermal and Adiabatic calorimetry methods, while still using the dry method, i.e. it is waterless. The minimum determination time is down to 4.5 minutes.
MORE ACCURATE RESULTS IN MINUTES – The CAL3K-A is one our faster calorimeter systems and is ideal for high sample throughput with more than 10 samples per hour. It uses a combination of the Isothermal and Adiabatic calorimetry methods and is still waterless. The minimum determination time is as little as 4.5 minutes per sample. The CAL3K-A makes use of the external oxygen filling station, bayonet bomb vessel and air cooler with the calorimeter. The CAL3K-A is the brother of the CAL3K-AP system, the major difference being the manual oxygen filling. This instrument has all the features of the CAL3K-AP, but avoids the potential trouble of leaking oxygen valves and fittings, and the associated maintenance. It can be operated in the Dynamic (Isoperibol), Isothermal, Adiabatic and Experimental modes, but requires calibration in each mode. The vessel is filled with oxygen in an EXTERNAL filling station which has a flow restriction and oxygen filter.
CAL3K-A OXYGEN BOMB CALORIMETER SYSTEM
The CAL3K-A conforms to ASTM D5865-12, ASTM D4809-13, ISO 1928-2009, and DIN 51900-2 international standards. The CAL3K bomb calorimeter uses the isothermal, adiabatic or isobatic calorimetry methods to measure temperature readings and to calculate the result in MJ, BTU or Calories.
The bomb vessel has been upgraded to include a self-locking and sealing bayonet vessel with built-in temperature sensors. The vessel is completely removable for easy sample management, cooling, cleaning and maintenance. Multiple vessels can be used in the same calorimeter, each with their own temperature calibration curves. Multiple vessels improve sample throughput and provides a higher redundancy should a vessel fail. While one vessel is in the calorimeter, the other can be cooled and prepared with the next sample.
The CAL3K-A calorimeter interfaces with different devices, including PC (PC Software), Balance, Printer and Bluetooth (Wireless). The unit also integrates fully with software based laboratory and information management systems (LIMS) and has a statistical print output in addition to the real time output.
The oxygen bomb calorimeter and air cooler are operated together for effective routine sample determination, using 2 or more bomb vessels . It is recommended to use the air cooler for optimum results and faster throughput. The air cooler works in conjunction with the CAL3K-A and gets its optimum cooling instructions from the CAL3K-A. This allows the air cooler to uniquely cool each bomb differently, should it be required. The coolest feature of the air cooler is the ambient temperature compensation, which allows for consistent fast cooling times regardless of the ambient temperature of the laboratory. The air cooler also displays the vessel temperature and the time until the bomb is ready to be used again, all this cooling for only 12 Watts!
The complete CAL3K-A oxygen bomb calorimeter system contains all the parts and consumables necessary to set up the unit. The installation kits included with the setup of the calorimeter contains consumables for approximately 200 samples, depending on the type of sample being analyzed (coal analysis, animal feed analysis). Other samples like oil, might use more consumables as they are corrosive and could cause wear and tear.
It is best suited for a production environment with shared oxygen supply (to other users) and robust handling. One external filling station can service multiple CAL3K Calorimeters. The DDS Calorimeters can be used to determine the calorific value of solid and liquid combustibles including oil, coke, volatile fuels, biomass, plastic, coal, animal feeds and foodstuffs. The calorific value of a combustible substance is a critical factor and differs from application to application. In a coal fired power station the cost of coal is calculated from the calorific value, providing economic benefits to the customer.
The applications for a DDS Bomb Calorimeter are endless with the common applications being scientific research, university research, coal mines and power stations, alternative energy/recycling, chemical industry, industrial inspection and quality control.
The CAL3K-A uses a combination of the Isothermal and Adiabatic calorimetry methods, while still using the dry method, i.e. it is waterless. The minimum determination time is down to 4.5 minutes.
The vessel is filled with oxygen in and EXTERNAL filling station which has a flow restriction and oxygen filter. The supplied filling pressure is indicated as well as the vessel pressure.
The fastest performance was achieved with one CAL3K-A , 3 vessels and 2 coolers. This is the limit of a single operator. It is possible to run the CAL3K-A Calorimeter with a single bomb vessel and achieve accurate and reliable results.
COMPLETE CAL3K OXYGEN CALORIMETER SYSTEM
The CAL3K calorimeter requires a PC keyboard (as seen above/left with the complete system) to enter commands. The new lid design has two shocks which open the lid automatically. This is really a nifty new feature. The CAL3K-A Oxygen Bomb Calorimeter will be supplied as a complete system which includes the calorimeter, the new air cooler , and 2 bayonet oxygen vessels.
The LCD display has 4 lines, the picture below only showing two of the lines. The first line shows what the CAL3K is doing at present, e.g. what mode the calorimeter is in and what it is doing.
The second line shows the action the operator should take, e.g. “ENTER MASS, INSERT BOMB”, etc. The third line is reserved for keyboard command and data entry, e.g. Enter Benzoic Acid Value in MJ. The fourth line gives additional information relating to faults and actions. If the subject help is activated then all 4 lines are used to display the help functions.
CALORIMETER WELL AND MANUAL FILLING
This is the CAL3K Oxygen Bomb Calorimeter with the lid open. The new gas shocks allow for automatic opening. The shocks open the lid to 45°C, so that the well can ventilate after each sample determination.
The ATC HEATER (Ambient Temperature Control) insulates the oxygen bomb vessel from the outside environment. It contains heating elements designed so that the ATC temperature follows the vessel temperature.
BOMB WELL – The bomb well has a contact arrangement at the bottom to connect to the bomb electronics. The vessel temperature and calibration data are retrieved from this contact.
The electronics compartment is located in the blue side panel of the calorimeter. This electronic compartment is the “brain” of the calorimeter, as we like to call it. This is what makes everything work. There you will find the firing circuit and the ECU card, which can easily be removed, making maintenance quick and easy.
The CAL3K Calorimeter has some added features which will make the operation of the oxygen calorimeter a lot easier and user friendly. Every step in the determination of the calorific value of the sample has a help screen attached and operator prompts assist with step-by-step instructions to operate the calorimeter.
EVENT LOGGING – The CAL3K-A has 63 event classifications and can store a maximum of 6800 logged events.
DEFAULT PARAMETER FIELDS – The CAL3K-A has 1 default parameter field for each mode. All fields are for different operation and operating modes.
FAULT AND FIELD TESTING CAPABILITY – The CAL3K-A and vessel each have a factory and a field test built in. The field test allows the operator/user to test the functionality without any instruments or special connections.
