Overview
The CC-2017E high and low temperature thermostatic circulator integrates heating and cooling functions. The water bath body is made of all stainless steel and insulated, providing an economical solution for the sample to be placed directly in the water bath for thermostatic testing. This model has a Tank volume of 17L and a Temperature range of -20~ 100 ° C. It comes standard with an external circulation adapter and an external temperature sensor PT100, which is suitable for sample temperature control, material testing, quality control and chemical analysis.
Features
Adopting professional proportional refrigeration control technology, the refrigeration capacity is output in proportion, and the Compressor does not need to run 100%, which is more energy-saving.
2. With CIT timely cooling technology, the Compressor can be directly started to cool down even at high temperatures.
3. Equipped with low liquid level protection function to prevent dry burning, and can set lighting and sound alarms.
4. Optional multi-stage programmable controller, to achieve timing heating, cooling, thermostatic and other multi-stage program control, the longest running time of each section can reach 999 hours.
5. Equipped with external temperature sensor interface, with PID TAC control, Cascade cascade control and bath inside and outside temperature lock control technology, can accurately control the bath outside the material temperature.
6. Adopt maintenance-free pressure/suction pump, resistant to fiber and metal particles, can carry out domestic circulation and external circulation, and carry out horizontal and vertical two-way stirring of bath liquid to make the temperature more uniform, pump pressure and Flow rate automatically adapt to external load.
7. Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics.
8. Using Pt100 temperature sensor, support two-point and multi-point temperature calibrating.
9. Removable trend dust net cover, easy maintenance.
10. The buzzer can be set to sound or silent.
11. Provide a variety of power failure recovery operation modes, which can automatically resume operation after unexpected power failure.
12. Optional intelligent control functions, including a variety of Communication interfaces (RS485, RS232), analog signal input (0-10V or 4-20mA), external touch points and switch signals, to achieve remote communication and control.
Principle
The thermostatic circulator monitors the bath bath temperature in real time through the intelligent PID Control system combined with the built-in Pt100 temperature sensor. The system adjusts the heater Power and Compressor cooling capacity proportionally according to the difference between the set temperature and the measured temperature to achieve precise temperature control. The circulation pump performs horizontal and vertical two-way stirring of the thermostatic medium (bath liquid) in the tank to ensure uniform temperature; at the same time, through the external circulation adapter, the thermostatic medium can be pumped to the external device to realize the temperature control of the external sample. Its CIT technology allows direct start of Compressor cooling at high temperatures, shortening the cooling time.
Applications
Sample temperature control, material testing, quality control, chemical analysis
Standards
Safety level III/FL can use flammability liquids according to DIN 12876
Steps
1. Place the equipment in a stable and well-ventilated position to ensure that the Ambient Temperature is 5~ 32 ° C and the relative humidity is ≤ 80%.
Connect the power supply (200~ 230VAC/50Hz).
3. Inject the appropriate amount of bath liquid into the bath to ensure that the liquid level meets the requirements.
4. Set the required temperature value and Miscellaneous parameters (e.g. program segment, time, etc.) through the control panel.
5. If external temperature control is required, connect the external temperature sensor PT100 and the external circulation pipeline.
6. Start the equipment, the circulating pump starts to work, and the equipment will automatically heat or cool to the set temperature and keep it thermostatic.
7. Place the sample to be tested in a bath or connect it to an external circulation circuit.
8. During the experiment, the status can be monitored through the panel or optional remote interface.
9. After the experiment, power off the equipment and perform cleaning and maintenance as required.
Notice
Equipment must be used under allowable environmental conditions (temperature 5~ 32 ℃, relative humidity ≤ 80%).
• Please ensure that the liquid level of the bath is sufficient before use to avoid low-level dry burning.
• Power supply voltage meets requirements (200~ 230VAC/50Hz).
• When performing external circulation, please connect the pipeline correctly to ensure good sealing.
Equipment allows continuous operation (100% duty cycle), but still requires regular inspection and maintenance.
During cleaning and maintenance, please disconnect the power supply.
• Optional functions (such as programming controller, Communication interface, etc.) need to be used according to the actual purchased configuration.
Please pay attention to the maximum pressure (0.3 bar) and maximum suction (0.2 bar) limits of the pump.
