CAL3K-S Oxygen Bomb Calorimeter System
CAL3K-S APPLICATION
Even though the CAL3K-S system is economical, the calorimeter will not compromise on accuracy and repeatability. It is used in Food/Feed Analysis, Alternative Energy, Waste Analysis, Forest Waste, Sugar Mills, Pulp & Paper Mills, Scientific Determinations, Coal and Oil Production, Research, Universities and Quality Assurance. In short : wherever the calorific value of a solid or liquid sample that must be determined, the CAL3K-S will be perfectly suited for the job.
CAL3K-S PERFORMANCE
The CAL3K-S uses a combination of the Dynamic (Isoperibol) method while remaining dry i.e. it is waterless. The determination repetitive cycle time is approximately 30 minutes for the CAL3K-S system. Once a sample has been loaded into the bomb vessel, a result can be expected within 9 minutes.
It uses the external oxygen filling station (3K-3) as part of the system.
For an affordable price, the fastest performance is 2 samples per hour, with the first result complete in 9 minutes.
COMPLETE CAL3K OXYGEN CALORIMETER SYSTEM
The CAL3K-S calorimeter requires a PC keyboard to enter commands. The lid design of the calorimeter has a manual door knob to open the lid once the determination has finished. The door latch has been designed to give years of reliable service and provide acknowledgement that the latch is securely locked.
The LCD display has 2 lines. It shows what the CAL3K-S is doing at present, e.g. what mode the calorimeter is in and in what stage of the determination it is presently in.
LCD SCREEN
The contents of the LCD Screen changes automatically as and when various commands are entered. The CAL3K-S calorimeter provides feedback to the operator along the various stages of the determination, as well as if an error or warning is observed.
CALORIMETER WELL AND MANUAL FILLING
This is the CAL3K-S Oxygen Bomb Calorimeter with the lid open. The lid is opened manually. Once open, the lid will rest at 100° angle, so that the bomb well can ventilate after each sample determination.
TOP CONTACT – Through the top contact the bomb is fired. This will make contact with the top of the center electrode of the bomb vessel when the LID is closed.
The design of the bomb well provides insulation to the outside ambient conditions. Once the LID is closed, the bomb vessel is sealed in the bomb well, insulating it from the outside. This allows the bomb to stabilize in temperature before it is fired.
OPERATOR ASSISTANCE
The CAL3K-S Calorimeter has some added features which will make the operation of the oxygen calorimeter a lot easier and user friendly. Every step in the preparation and determination sequence of a sample will be automatically displayed for the operator to follow.
DEFAULT PARAMETER FIELD – The default parameters can be invoked from a keyboard command. This feature assures the most important parameters are reset to factory standard, ensuring a fully functional calorimeter again.
FAULT AND FIELD TESTING CAPABILITY – The CAL3K-S 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. Each factory test is time stamped and visible in the log file. Should the factory test or vessel test fail, it will stop at the highlight fault. Most of the faults can be easily repaired, others will require an agent.
MAX RECORDING
The vessel records the amount of firings, the max temperature and the date and time. The CAL3K-S records the max starting temperature, the max ambient temperature and date/time. It also records the amount of firings, mass firings, bomb aborts, manual fired and suspect result.
CAL3K Thread Type Bomb Vessels
The traditional CAL2K-4 bomb vessel has been replaced with a self-locking and sealing 4K-4 thread type vessel with built-in temperature sensors. The vessel is completely removable for easy sample management, cooling, cleaning and maintenance.
The CAL3K thread type (self-locking and sealing) vessel has a stainless steel body with a reduced mass (approx. 1.9kg) and a pressed on aluminium sleeve which acts as a heat sink and temperature equalizer. This sleeve performs the task of the traditional water and stirrer.
The oxygen bomb calorimeter and bomb vessel are operated together for effective routine sample determination - for optimal results and faster throughput use 2 or more vessels. Please note that other bomb vessels like the bayonet bomb vessel were supplied with our systems prior to 2023.
