The DL30-300 circulating chill down device is a low temperature cycle equipment produced by GREATWALL, which is suitable for chemical, biological and physical testing experiments that need to maintain low temperature conditions. It adopts a closed circulation system to effectively prevent refrigerant volatilization and pollution, and is equipped with a variety of safety protection functions to ensure stable and reliable operation of the equipment.
1. Adopt brand fully enclosed Compressor, low noise, high Reliability, to ensure long-term stable operation of the product. 2. Adopt domestic high-performance circulating pump or foreign imported high voltage vane pump, high voltage pump pump pressure can be adjusted, mass reliable. 3. Adopt a closed circulation system to effectively prevent the evaporation and pollution of the refrigerant and save resources. 4. An filtrating device is installed in the circulation pipeline to prevent blockage of the circulation pipeline. 5. Adopt a fluorine-free green refrigerant (R410a) that does not contain chlorofluorocarbons, meeting international environmental refrigerant standards. 6. Small size and beautiful appearance. 7. Equipped with a liquid level display tube, it can monitor the liquid level in the built-in liquid storage tank. 8. The refrigerant outlet is equipped with a pressure gauge to display the pressure of the refrigerant. 9. Specification models to meet user requests. 10. The left and right side panels are easy to disassemble and easy to maintain.
The circulating chill down device drives the refrigeration cycle through a fully enclosed Compressor, removing heat from the refrigerant in the built-in liquid storage tank to achieve cooling. The temperature is controlled and displayed by a digital meter and a Pt100 temperature sensor. The cooled refrigerant is delivered to the external equipment that needs to be cooled down through a circulation pump (which can provide a maximum 20L/min Flow rate and 0.4bar pressure), and then heat exchange is returned to form a closed circulating chill down circuit.

International environmental refrigerant standards
1. Check whether the equipment Power supply voltage (220V, 50Hz) and environmental conditions (temperature 5~ 35 ℃, relative humidity ≤ 70%) meet the requirements. 2. Confirm that the refrigerant level in the liquid storage tank is sufficient through the liquid level display tube. 3. Correctly connect the external circulation pipeline with the threaded interface (1/2) of the equipment. 4. Turn on the power supply, and the equipment performs safety self-test (including protection functions such as delay, leakage, overcurrent, and overheating). 5. Set the required temperature value on the digital instrument (Temperature range -30~ RT ℃ or -30~ 5 ℃). 6. Start the equipment, Compressor and circulation pump start working. 7. Observe the pressure gauge, monitor the circulating pressure of the refrigerant, and adjust the pressure through the pump. 8. After the equipment operates stably, the temperature will be maintained near the set value (Temperature Stability +/- 2 ° C). 9. After use, turn off the device according to the procedures and disconnect the power supply.
• Please ensure that the device operates at the allowable Ambient Temperature (5~ 35 ° C) and relative humidity (≤ 70%). • Please check whether the Power supply voltage is 220V/50Hz before use. • Pay attention to observe the liquid level display tube to ensure that the refrigerant level is sufficient. • The circulation pipeline connection should be firm to prevent leakage. • When the equipment is running, do not block the entry and exit trends to ensure good heat dissipation. • Regularly check the filtrating device of the circulating pipeline to prevent blockage. Before performing equipment maintenance, be sure to disconnect the power supply. • Pay attention to safety when moving or handling equipment (weight 70kg). • Please use a refrigerant that meets the requirements and follow environmental regulations to dispose of waste refrigerants.
