The BC227 bath thermostatic circulator is a thermostatic circulator with heating head. With the help of external circulating water or chilled down liquid tank, the temperature can reach room temperature or -20 ° C. The bath body is made of all stainless steel and filled with aluminum silicate cotton insulation, which provides an economical solution for the sample to be placed directly in the bath for thermostatic test. Optional external circulation adapter and external temperature sensor PT100 can be used for external temperature control and circulation applications, suitable for sample temperature control, material testing, quality control, analysis and other fields. The use of environmentally friendly natural refrigerants, with liquid level protection and over-temperature protection, according to Safety level III/FL, can use flammability liquids, according to DIN 12876.
1. Hardware over-temperature protection, users can set the protection temperature through the knob, and dry burning can still be avoided when the equipment program fails. It meets the DIN12876 standard level III and can use flammability bath liquid. 2. Maintenance-free pressure/suction pump, pump pressure and Flow rate automatically adapt to external load. 3. Optional multi-stage programmable controller, can achieve multi-stage program control, such as timing heating, cooling, thermostatic, slope and each period of time, the longest time 999 hours. 4. Equipped with external temperature sensor interface, optional movable external temperature sensor, with PID TAC control technology, Cascade cascade control technology and bath internal and external temperature lock control technology, can accurately control the bath external material temperature. 5. Pt100 temperature sensor, single point, two point and multi point temperature calibrating. 6. Parts that come into contact with liquids or vapors are made of high-performance stainless steel and high-performance plastics. 7. Optional related accessories can be used to form different internal and external applications. 8. The buzzer can be set to silent or audible. 9. A variety of operation modes are optional, and accidental power failure can be automatically restored (mode 1: power-on equipment stops after power failure, and the set value can be changed; mode 2: power-on automatic operation after power failure, and the set value can be changed; mode 3: power-on automatic operation after power failure, and the set value cannot be changed). 10. The device serial number can be queried through the software. 11. Optional intelligent control functions: a variety of interfaces (RS485, RS232), to achieve remote communication, control equipment start and stop. 12. Optional normally open and normally closed 2 external contact points, can be connected to external alarms. 13. Optional set of 12V switch Output signal for controlling external solenoid valve. 14. 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. 15. Optional 0-10V or 4-20mA analog signal input can be used for external smart devices to control the start and stop of the instrument.
The thermostatic circulator is heated by a built-in heating head and cooled down by heat exchange between the chilled down coil and the external circulating water or chilled down tank, resulting in a stable temperature environment in the bath. The intelligent PID Control system combines the Pt100 temperature sensor to precisely monitor and regulate the temperature, and the pressure/suction pump automatically adapts to the external load to maintain the circulating Flow rate, ensuring uniform and stable temperature in the tank.

DIN 12876
1. Place the device on a stable table and connect it to a power supply (200~ 230VAC/50Hz). 2. Inject an appropriate amount of working liquid into the bath (pay attention to liquid level protection). 3. Connect the external circulation pipeline (interface M16x1mm) or optional external temperature sensor as required. 4. Set the target temperature, protection temperature and operation mode through the control panel. 5. Start the equipment, the pump starts working, and the heating/cooling down system runs to reach the set temperature. 6. Place the sample in the bath or perform the thermostatic test by external circulation. 7. After the test, turn off the power of the equipment and empty or clean the bath.
• Power supply voltage meets requirements (200~ 230VAC/50Hz) before use. • Equipment Ambient Temperature should be maintained at 5~ 32 ℃, relative humidity ≤ 80%. • The liquid injected into the bath shall not exceed the allowable liquid level, and pay attention to whether the selected liquid meets the Safety level (if using flammability liquid, ensure that it meets the Class III/FL standard). • Avoid running the equipment without liquid or with low liquid level to prevent dry burning damage. • Regularly check whether the pump, pipeline and temperature sensor are normal to ensure smooth circulation. When calibrating the temperature, use a standard Pt100 Sensor and follow the procedure. • When the equipment is not used for a long time, it is recommended to empty the bath and keep it drying. • Be sure to disconnect power before moving or maintaining equipment. • When selecting external control functions, please follow the instructions to connect the wires correctly to avoid short circuits or signal interference.
