Overview
The LABTOP CC-2020 high and low temperature thermostatic circulator integrates heating and cooling functions. It uses an all-stainless steel water bath body and thermal insulation cotton to keep warm, providing an economical solution for the sample to be placed directly in the tank for thermostatic test. This model has a Tank volume of 20L and a Temperature range of -20~ 220 ℃. It comes standard with an external circulation adapter and an external temperature sensor PT100. The pump is powerful and suitable for temperature control, material testing, quality control and chemical analysis of samples. The instrument uses environmentally friendly natural refrigerants and has liquid level protection and over-temperature protection functions.
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. Equipped 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 sound and light alarms.
4. Optional multi-stage programmable controller to achieve regular heating, cooling, thermostatic and slope control, the longest running time of each program can reach 999 hours.
5. Equipped with external temperature sensor interface, with PID TAC control, Cascade cascade control and bath temperature difference lock control technology, can accurately control the external material temperature.
6. Adopt maintenance-free pressure/suction pump, resistant to fiber and metal particles, can carry out domestic circulation or external circulation, and carry out horizontal and vertical two-way stirring of bath liquid, 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 plastics.
8. Using Pt100 temperature sensor, support two-point and multi-point temperature calibrating.
9. Equipped with removable trend dust net cover, easy maintenance.
10. The buzzer can be set to either sound or silent mode.
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 RS485, RS232 Communication interface, 0-10V or 4-20mA analog signal input, as well as external touch points, switch Output signals, etc., support remote communication and control.
Principle
The thermostatic circulator precisely adjusts the output of Heating power and refrigeration Compressor through intelligent PID Control system. Its core lies in the proportional refrigeration control technology, so that the cooling capacity can be adjusted proportionally according to actual needs, rather than simple start and stop, combined with CIT technology implementation of rapid cooling. The instrument monitors the temperature in the tank through the built-in Pt100 Sensor, and can realize the cascade precise temperature control of external materials through the external Sensor. The circulation pump drives the heat conducting medium (bath liquid) in the domestic circulation of the system, and ensures uniform temperature through horizontal and vertical stirring. The system has multiple Safety protection mechanisms to ensure stable and reliable operation.
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 device in a stable, well-ventilated position and connect the power supply (220VAC 50HZ).
2. Inject an appropriate amount of heat transfer medium (bath liquid) into the stainless steel water bath to ensure that the liquid level meets the requirements.
3. Turn on the power switch and set the required temperature, time and other parameters through the LED display and controller.
4. If you need to control the temperature of the external material, connect and install the external temperature sensor PT100.
5. Connect the external circulation pipeline (interface M16x1) as needed, and select the domestic circulation or external circulation mode.
6. Start the equipment, the circulating pump starts working, and the equipment will automatically heat or cool to achieve and maintain the set temperature.
7. During operation, the temperature and other conditions can be monitored in real time through the display screen.
8. After the experiment, first stop the heating/cooling, then turn off the circulating pump, and finally turn off the power switch.
9. Empty or properly dispose of the heat transfer medium in the bath, and perform cleaning and maintenance.
Notice
* Ambient Temperature of the equipment is 5~ 32 ℃, relative humidity ≤ 80%, please ensure that it is used in a suitable environment.
Please check the liquid level before use to prevent low-level dry burning and ensure that the liquid level protection function is normal.
* Do not block the trend or trend when the equipment is running, and clean the removable dust net cover regularly.
When connecting external circulation lines, ensure that the interface is firmly secured to prevent leakage.
Equipment allows continuous operation (100% duty cycle), but long-term operation requires attention to observe the operating state.
Before moving or cleaning equipment, be sure to disconnect the power supply.
* Power supply voltage (220VAC 50HZ) and ensure good grounding.
* If you need to use a flammability liquid as a bath liquid, please ensure that the operation complies with the relevant regulations of Safety level III/FL.
* When calibrating temperature, use a standard Pt100 Sensor and follow the relevant procedures.
The device has an over-temperature protection function, but users still need to avoid setting the limit temperature beyond the allowable range (-20~ 220 ° C).
