Overview
The CC-2020E high and low temperature thermostatic circulator integrates heating and cooling functions. The water bath body is made of all stainless steel, and the outside is insulated by thermal insulation cotton, which provides an economical solution for the sample to be placed directly in the water bath for thermostatic test. It is suitable for temperature control, material testing, quality control, analysis of samples, etc., using environmentally friendly natural refrigeration, with liquid level protection and over-temperature protection functions.
Features
1. Professional proportional refrigeration control technology, the refrigeration capacity is proportional output at the control point, the Compressor does not need 100% output, more energy saving
2. CIT timely cooling technology can directly start Compressor cooling even at high temperatures
3. Low liquid level protection to prevent dry burning
4. Optional multi-segment programmable controller, users can implement multi-segment program control
5. Configure external temperature sensor interface, optional movable external temperature sensor
6. Domestic circulation, external circulation, maintenance-free pressure/suction pump
7. Multiple safety protection: low liquid level protection, light and sound can be reminded at the same time when alarming
8. High-performance stainless steel and high-performance plastics are used for parts that come into contact with liquids or steam
9. Pt100 temperature sensor for two-point and multi-point temperature calibrating
10. Removable trend dust net cover, maintenance is very convenient
11. The buzzer can be set to silent or sound
12. Multiple operation modes are available, and accidental power failure can be automatically restored
13. Optional intelligent control function: multiple interfaces (RS485, RS232) for remote communication
14. Optional 0-10V or 4-20mA analog signal input
15. The device serial number can be checked through the software
16. Optional normally open and normally closed 2 external contact points, can be connected to external alarms
17. Optional set of 12V switch Output signal for controlling external solenoid valve
18. An optional set of 5V external input switch signals can be used for external smart devices to control the start and stop of the instrument
Principle
The equipment adopts intelligent PID temperature Control mode, real-time monitoring of temperature through Pt100 temperature sensor, combined with professional PID TAC control technology, Cascade cascade control technology and temperature difference lock control technology inside and outside the bath, accurately control the temperature of materials inside and outside the bath. Output cooling capacity on demand through proportional refrigeration control technology, cooperate with CIT timely cooling technology implementation to quickly cool down, and at the same time, stir the bath liquid in both horizontal and vertical directions through pressure/suction pump to make the temperature distribution more uniform.
Applications
Sample temperature control, material testing, quality control, analysis
Standards
Safety level III/FL can use flammability liquids, DIN 12876
Steps
1. Connect the power supply (200~ 230VAC/50Hz)
2. Check the liquid level to ensure it is within a safe range
3. Set the required temperature parameters
4. Select the operation mode (Mode 1, Mode 2 or Mode 3)
5. Start the device running
6. External circulation adapter and external temperature sensor can be connected as needed
7. Monitor equipment operation status
Notice
• Equipment should be used at Permissible Ambient Temperature 5~ 32 ° C and relative humidity 80%
• Make sure the liquid level is normal before use to prevent dry burning
• Regularly clean the trending dust net cover
• Pay attention to the maximum pressure of the pump 0.3bar and the maximum suction force 0.2bar limit
• The equipment is fixed by Floor-Standing and needs to be placed smoothly
• Safety level III/FL requirements when using flammability liquids
• After the power is disconnected, it can automatically resume operation according to the set mode
