Overview
The LABTOP CC-2017 high and low temperature thermostatic circulator integrates heating and cooling functions. The water bath body is made of all stainless steel and supplemented with thermal insulation cotton insulation, providing an economical solution for the thermostatic test of the sample directly placed in the tank. The model has a Tank volume of 17L and a Temperature range of -20~ 220 ℃. It comes standard with an external circulation adapter and an external temperature sensor PT100. The pump pressure can reach 0.3 bar and the suction force can reach 0.2 bar. It is suitable for the fields of temperature control, material testing, quality control and chemical analysis of samples.
Features
1. Using professional proportional refrigeration control technology, the refrigeration capacity is output in proportion, and the Compressor does not need to run at full load, 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 sound and light alarms.
4. Optional multi-stage programmable controller, support timing 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. With 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 can automatically adapt to external loads.
7. Components that come into contact with liquids or vapors are made of high-performance stainless steel and plastics.
8. Use the Pt100 temperature sensor to support two or more point temperature calibrating.
9. The trend dust net cover is removable for easy maintenance; the buzzer can be set to sound or silent mode.
10. Provide a variety of power failure recovery operation modes, which can automatically resume operation after unexpected power failure.
11. Optional intelligent control functions, including RS485, RS232 Communication interface, 0-10V/4-20mA analog signal input, external touch point and switch signal, support 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 (using proportional refrigeration technology) to achieve fast and accurate temperature control. The liquid in the tank is carried out domestic circulation or external circulation through the maintenance-free pressure/suction pump. The pump simultaneously agitates the bath liquid in the horizontal and vertical directions to ensure uniform temperature in the tank. When the external Sensor is connected, the system can activate the cascade control mode to precisely control the material temperature of the external container.
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 and well-ventilated position and connect the power supply (200~ 230VAC/50Hz).
2. Inject an appropriate amount of heat transfer medium into the stainless steel bath to ensure that the liquid level is higher than the heating tube and avoid low-level dry burning.
3. Turn on the power switch and set the required temperature value (resolution 0.01 ° C) through the LED display.
4. To control the external container temperature, connect the standard external PT100 temperature sensor.
5. Select the domestic circulation or external circulation mode as needed, and connect the corresponding pipeline (pump interface is M16x1).
6. Start the equipment and the system will automatically start heating or cooling until it reaches and stabilizes at the set temperature.
7. The sample to be tested can be placed in the bath or external circulation system for thermostatic test.
8. After the test, turn off the power of the equipment and drain or properly dispose of the heat transfer medium in the bath.
Notice
• Ambient Temperature of equipment should be maintained at 5~ 32 ℃, relative humidity ≤ 80%.
• Be sure to ensure that the liquid level in the bath is sufficient before use to prevent low liquid level protection from triggering or dry burning damage to the equipment.
• When carrying out external circulation, please ensure that the external pipeline connection is firm and there is no leakage.
• The equipment allows 100% continuous operation, but it is necessary to ensure that the surrounding is well ventilated, and the trend dust net cover should be cleaned regularly.
• Be sure to disconnect power before moving or cleaning equipment.
• Power supply voltage that meets the requirements of the equipment to avoid damage caused by unstable voltage.
• If you need to use flammability liquid as heat transfer medium, please ensure that the operating environment meets the relevant regulations of Safety level III/FL.
