Overview
YIHENG BWR-03A circulating chill down device is a new generation of small circulating chill down equipment, using fluorine-free design, green environmental protection. Introduced and digested foreign technology, it has the characteristics of accurate temperature control, small volume, low noise, fast Flow rate, fast cooling, high efficiency, low energy consumption, etc. Compared with traditional equipment, the cooling time is reduced by 35% and the service life is long.
Features
1. LCD controller, one screen display of multiple sets of data, Menu Operating interface, accurate and reliable temperature control, can confirm the operation of the instrument at any time.
2. Compressor overheating, overload protection, bath solution temperature is high, low and refrigeration system overpressure display flashing beep alarm.
3. Open bath can be used as pre-freezing tank, low temperature tank, put into Glass ware, suitable for acid solution and organic solution thermostatic test.
4. Open the bath cover to facilitate real-time observation of the condensate state in the bath.
5. The heat exchanger tube is made of 304 stainless steel, which is resistant to abrasion, vibration is not easy to break, easy to clean and easy to maintain.
6. The front gear plate adopts magnetic adsorption design, no need to disassemble tools, can quickly open the cover plate to clean condenser dust.
7. Compact design to meet the requirements of small space laboratories.
8. A circulating chill down can chill down multiple Rotary evaporators at the same time to achieve multi-purpose.
9. Optional R485 Communication interface for computer display or export of experimental data, support data storage and playback.
Principle
The circulating chill down device drives the refrigeration system through the Compressor, uses R404A refrigerant to achieve rapid cooling, and the circulating pump provides high Flow rate liquid circulation to ensure stable solution temperature in the bath. The controller precisely monitors and adjusts the temperature, triggering an alarm protection mechanism when the temperature is abnormal or the system is overpressurized.
Applications
Laboratory thermostatic test, Rotary evaporator chilling down, acid solution thermostatic, organic solution thermostatic, pre-freezing tank application, low temperature tank application
Steps
Connect the power supply and ensure that the voltage is AC220V +/- 10%/50Hz.
2. Turn on the device and set the required temperature parameters through the LCD display controller.
3. Place the experimental solution or Glass vessel in an open bath.
4. Start circulating pump and refrigeration system to monitor Temperature Stability.
5. During the experiment, the bath cover can be opened to observe the condensate state in real time.
6. Turn off the equipment after use, and clean the heat exchanger tube and condenser if necessary.
Notice
• Power supply voltage meets AC220V +/- 10%/50HZ requirements to avoid overvoltage or undervoltage operation.
• Pay attention to Compressor overheating and overload protection alarms during operation, and deal with abnormal situations in time.
• The temperature of the solution in the bath should be controlled within the range of -20~ 20 ° C to avoid exceeding the Temperature range.
• Regularly clean the heat exchanger tube and condenser to keep the equipment clean and prevent dust accumulation.
• When using the magnetic adsorption front gear, no tools are required, and light operation is required to avoid damage.
When the equipment is running, the noise of the whole machine should be controlled at ≤ 45 decibels. If there is any abnormality, it needs to be checked.
• When adapting Rotary evaporator, pay attention to the volume limit to avoid overloading.
• When selecting the R485 Communication interface, connect the computer correctly to ensure the safety of data export.
