Overview
The LABTOP CC-1008 high and low temperature thermostatic circulator integrates heating and cooling functions, and uses an all-stainless steel water bath body and thermal insulation cotton insulation, providing an economical solution for placing samples directly in the tank for thermostatic testing. This model has a Tank volume of 8L, Temperature range -10~ 200 ℃, and is equipped with a pressure/suction pump to support domestic circulation and external circulation applications.
Features
Adopting professional proportional refrigeration control technology, the refrigeration capacity is output proportionally, and the Compressor does not need 100% output, 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 the light and sound alarm at the same time.
4. Optional multi-stage programmable controller, to achieve timing heating, cooling, thermostatic and other multi-stage program control, each period of up to 999 hours.
5. Equipped with external temperature sensor interface, optional mobile external temperature sensor, combined with PID TAC control, Cascade cascade control and bath temperature difference lock control technology, precise control of external material temperature.
6. Using maintenance-free pressure/suction pump, resistant to fiber and metal particles, the bath liquid can be stirred horizontally and vertically to make the temperature more uniform, and the pump pressure and Flow rate automatically adapt to the 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. Equipped with removable trend dust net cover, easy maintenance.
10. The buzzer can be set to silent or audible 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 a variety of Communication interfaces (RS485, RS232), analog signal input (0-10V or 4-20mA), external touch points and switch signals, support remote communication and control.
Principle
The device monitors the bath temperature in real time through the intelligent PID Control system combined with the built-in Pt100 temperature sensor. The system proportionally adjusts the output of the heater Power and the refrigeration Compressor according to the difference between the set temperature and the measured temperature to achieve accurate temperature control. The circulation pump drives the bath liquid to circulate in the tank or through the external circulation adapter, and ensures uniform temperature through horizontal and vertical two-way stirring. When equipped with an external temperature sensor, cascade control technology can be used to preferentially adjust according to the temperature of the external material to achieve more accurate external temperature control.
Applications
Sample temperature control, material testing, quality control, analysis
Standards
Safety level III/FL can use flammability liquids according to DIN 12876
Steps
1. Place the device in a stable and well-ventilated environment and connect the power supply (200~ 230VAC/50Hz).
2. Add an appropriate amount of heat transfer medium to the Tank to ensure that the liquid level meets the requirements.
3. Turn on the power switch and set the required temperature parameters through the LED display.
4. If external temperature control or circulation is required, connect the external temperature sensor PT100 and the external circulation pipeline.
5. Start the equipment, the heating or cooling system starts working, and the circulating pump runs simultaneously.
6. After the equipment reaches the set temperature and stabilizes, the sample can be placed in a tank or connected to an external circulation system for experimentation.
7. After the experiment, power off the equipment, remove the sample, and perform cleaning and maintenance as required.
Notice
• Permissible 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 avoid triggering protection or dry burning due to low liquid level operation.
• Power supply voltage in the range of 200~ 230VAC, and reliable grounding.
• The device is Floor-Standing, please place it on a stable plane and leave enough heat dissipation space.
• The maximum pressure of the pump is 0.2 bar, and the maximum suction force is 0.1 bar. Do not use it beyond this load.
• If using flammability liquids, ensure that they meet the requirements of Safety level III/FL and take good safety precautions.
• Regularly clean the removable trend dust net cover to ensure the normal heat dissipation of the equipment.
When calibrating the temperature, use a qualified Pt100 Sensor and follow the procedure.
• According to the experimental requirements, set the power failure recovery mode correctly in the device menu (such as automatic operation, parameter locking, etc.).
• Optional external alarms, solenoid valves and other Accessories, please connect and use correctly according to the instructions.
