CAL3K-S Calorimeter

CAL3K-S Oxygen Bomb Calorimeter System

The Cal3k-S Bomb Calorimeter is a powerful entry level system for low throughput without compromising on accuracy and repeatability. The Cal3k-S calorimeter has a compact size, low energy consumption and boasts a large list of features with an unbeatable price tag.

APPLICATION : An economical system is typically used in application where low sample analysis is required, like in Food/Feed Analysis, Alternative Energy, Manufacturing, Coal and Oil Production, Research, Universities and Quality Assurance. In short : wherever the calorific value of a solid or liquid sample must be determined, the Cal3k-S is the economical calorimeter of choice.

The Cal3k-S system contains a calorimeter, bayonet bomb vessel and oxygen filling station. A spare bomb vessel (3k-5) can be purchased as a spare, however this will not increase the speed of the system. The calorimeter system can complete up to 2 samples per hour. Part of the Cal3k-S system is the external oxygen filling station (3k-3), standard across all manual filling calorimeter systems. The Cal3k-S is a totally dry type calorimeter, making it environmentally friendly and energy efficient. The Cal3k-S also boasts the smallest carbon footprint in its class.

The Cal3k-S Oxygen Bomb Calorimeter is economically positioned to be an affordable entry type calorimeter with features its competitors wished they had.

The system uses the proven bayonet vessel common to all Cal3k systems and works in the dynamic (Isoperibol) mode. It has two communication ports with dual purposes, catering for almost every application.

CAL3K-S OXYGEN BOMB CALORIMETER SYSTEM

The Cal3k-S conforms to ASTM D240-09, ASTM D5865-12, ASTM D4809-13, ASTM E711-87, ISO 1928-2009, ISO 18125-2017, GB/T213-2008 and DIN 51900-2 International standards. The Cal3k-S bomb calorimeter uses the Dynamic (Isoperibol) method to measure temperature and calculate the calorific value.

The heart of the system is the quick-locking and sealing bayonet vessel with built-in temperature sensors. This vessel is a dry type vessel, enabling it to be more accurate and faster. Having a fast, accurate dry bomb vessel can only be environmentally friendly. The vessel is completely removable from the bomb well for easy sample preparation, cooling, cleaning and maintenance.

The Cal3k-S interfaces with different devices, including PC (PC Software), Balance, Printer and Laboratory and Information Management Systems (LIMS) and Bluetooth (Wireless). Since the calorimeter only has two input / output ports, the user will need to select which external appliance to plug in.

The Cal3k-S oxygen bomb calorimeter does not come with a Cal3K-2 Air cooler, but can be added for a slight increase in speed. For best results, the calorimeter is designed to run with a single bomb vessel. The economical Cal3k-S system presently comes in one system configuration.

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 of is 2 samples per hour, with the first result complete in 9 minutes.

SYSTEM EXPANSION

The following system components can be added to the Cal3k-S Oxygen Bomb Calorimeter (or purchased separately at a later stage) :

  • Bayonet Bomb Vessel (3K-5)
  • An extra bomb vessel is the only component that can be added to the Cal3k-S system as a spare, it will not influence the speed of the system.
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.

EVENT LOGGING – The Cal3k-S has 80 plus event classifications and can store a maximum of 6800 logged events. A short managerial daily summary is available on the D1 port with the statistical output enabled. The event logs record every step, process, function and operator interaction with the calorimeter.

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.

REAL TIME (RT) OUTPUT

The real time printer output is available for external data analysis/computation. This feature is used by universities. The RT printout is available with preceding header and important parameters.

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?

Coal & 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 Application

Explosives 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 Application

Fuel 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.

Food & 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.

Oil 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.
