There are basically two different ways to deal with the heat generated by the combustion of the sample in the bomb and transferred to the water in the bucket and to a lesser extent, to the water jacket. These are:
1. Open Loop. In an open loop system, the water in the bucket is 3 to 10 °C above the starting temperature and is dumped down the drain and replaced with cool fresh water from the tap. If the laboratory has supply of good quality, cool tap water and a convenient drain, an open loop system requires a bare minimum of accessories.
2. Closed Loop. In a closed loop system, the bucket and jacket water is recycled to a holding tank and circulated through a cooler to bring the water back to the desired starting temperature. Users who wish to operate independently from tap water and drains or where water supplies may be high in mineral contents which over time can deposit in the calorimeter will prefer this mode of operation even though it requires the addition of a cooler and a recirculation system.
6400 CALORIMETER OPERATION
The 6400 Calorimeter has a built in closed loop water handling system.
6300 CALORIMETER OPERATION
6520A Water Handling System
The 6300 Calorimeter has been designed to operate in either open or closed loop mode.
For Open Loop operation, the tap water is brought into the back of the calorimeter and the hot water discharge line is fed to the drain. The speed at which the calorimeter will recycle between tests is a function of the temperature of the incoming tap water. The performance will slow noticeably above 20 °C and will become sluggish above 25 °C. A 1552 Water Cooler can be installed on the inlet line to assure adequate cooling water and faster recycle times.
For Closed Loop operation, we offer the 6520A Water Handling System. The 6520A Water Recirculation System includes a recirculation pump, a receiver into which the bucket water from the calorimeter drains, and an integral thermoelectric cooler that eliminates the need for a stand alone cooler.
Note: The 6300 Calorimeter drains by gravity, so the 6520A Water Handling System must be installed below the calorimeter (not on the bench top) for closed loop operation.

6200 CALORIMETER OPERATION
6510 Water Handling System
The 6200 Calorimeter has been designed to operate in either the open or closed loop mode. While the 6300 Calorimeter automatically measures its own bucket water, in the 6200 Calorimeter, the operator must make provisions for precisely adding the 2000 mL of water at a repeatable starting temperature at the start of each test. The closed loop systems handle this task, as well as the other functions of closed loop systems discussed above.
For Open Loop operation in the 6200 Calorimeter, tap water is brought into the back of the calorimeter and the heated water is fed to the drain. Since this water is only used for cooling the jacket, the 6200 Calorimeter can operate efficiently with the tap water temperature up to 25 °C. Water for the bucket is normally drawn from a faucet supply and will need to adopt a constant and initial temperature compatible with the water supply.
For Closed Loop operation of the 6200 Calorimeter we offer the 6510 Water Handling System. The 6510 Water Handling System provides a convenient means for filling the bucket in the calorimeter with the same amount of temperature controlled water for each test run. It also serves as a source of temperature controlled water for maintaining a constant jacket temperature in the 6200 Calorimeter. It consists of a 5 gallon, temperature controlled reservoir with a built-in circulating pump, an attached 2000 mL glass delivery pipette and provision for continuous filtration of all water in the system.
There is built in thermoelectric cooling in a compact package to deliver a precise amount of temperature controlled water for filling the bucket and provide cooling water for the jacket when required.
Note: The 6510 Water Handling System operates on the bench top, next to the calorimeter.
6510 Water Handling System Instructions 454M
6100 CALORIMETER OPERATION
The 6100 Calorimeter does not have a temperature controlled jacket, so there is no water connection to the calorimeter. For Open Loop operation, the user will need to provide the bucket water as in the 6200 Calorimeter operation.
The 6510 Water Handling System described above is an effective means of supplying the temperature controlled and measured water to the bucket and we recommend automating these tasks for installations with sustained testing loads.
Advantages of Open Loop Systems
- Lower costs
- Fewer hookups and accessories
- Less maintenance
- Included with the calorimeter (6300 & 6200)
Advantages of Closed Loop Systems
- Conserves Water
- Eliminates problems caused by poor quality water supplies
- Provides uniform temperature starting water
- Eliminates the need for a drain
- Provides a repeatable amount of water for the bucket (6100 & 6200)
