DL30-2500 Circulation chill down 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 the evaporation of the refrigerant and is equipped with a variety of safety protection functions.
1. Adopt brand fully enclosed Compressor, low noise, high Reliability, to ensure long-term stable operation. 2. Using domestic high performance circulating pump or imported high voltage vane pump, pump pressure adjustable, reliable mass. 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 chlorofluorocarbon-free, fluorine-free green and environmentally friendly refrigerant, 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 equipment uses a fully enclosed Compressor refrigeration system to chill down the refrigerant in the built-in liquid storage tank to a set temperature. Then the low-temperature refrigerant is pumped out by the circulation pump and transported to the external equipment (such as reactors, instruments, etc.) that needs to be chilled down through the external circulation interface. After heat exchange, the temperature-increased refrigerant is returned to the equipment to chill down again, forming a closed circulation loop, thereby continuously providing low-temperature chilling down conditions for external equipment.
Chemical, biological, physical testing experiments, Food processing, chemical industry, Universities & colleges or scientific research laboratories. Specifically include: atomic absorption, ICP\ ICP-MS, nuclear magnetic resonance, biological fermentation tank, chemical reactor (synthesizer), electron microscope, X-Rays diffraction, X-fluorescence, magnetron sputtering, vacuum coating machine, laser, etc.
International environmental refrigerant standards
1. Place the device in a stable position with Permissible Ambient Temperature (5~ 35 ° C) and relative humidity (≤ 70%). 2. Connect the required power supply (3~ 380V, 50Hz). 3. Confirm that the refrigerant level in the liquid storage tank is normal through the liquid level display tube. 4. Use threaded connections (3/4) to properly connect external circulation lines to equipment that needs to be chilled down. 5. Turn on the power supply and set the required temperature through the digital temperature display instrument (Temperature range -30~ RT ℃). 6. Start the equipment and observe whether the pressure gauge indicates normal circulation pressure. 7. After the equipment is running, monitor the temperature Stability （ +/- 2 ° C) and operating status.
• Please ensure that the device operates at the allowable Ambient Temperature (5~ 35 ° C) and relative humidity (≤ 70%). • Must use a power supply that meets the specifications (3~, 380V, 50Hz). • Regularly check the liquid level of the storage tank through the liquid level display tube, and replenish the refrigerant in time. • Pay attention to the circulating pressure gauge to ensure that the pressure is within the normal range. • The equipment has safety protection functions such as delay, overcurrent, and overheating. If the protection is triggered, please check the cause before starting. • During maintenance, the left and right side panels can be removed for operation, but it needs to be carried out in a power-off state. • The filtrating device in the circulation pipeline needs to be checked or cleaned regularly to prevent blockage. • Device weight up to 195kg, pay attention to safety when moving or installing. • Please use a refrigerant that meets environmental protection requirements and is compatible with the material of the equipment (such as SUS304 liquid storage tank).
