The DL30-700 Circulation Chill down is a low temperature cycle equipment manufactured by GREATWALL, suitable for chemical, biological, physical testing experiments that need to maintain low temperature conditions, as well as Food processing, chemical, Universities & colleges or research laboratories.
1. Adopt brand fully enclosed Compressor, low noise, high Reliability, to ensure long-term stable operation. 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 refrigerant volatilization and pollution, 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 refrigerant pressure. 9. Specification models to meet user requests. 10. The left and right side panels are easy to disassemble and easy to maintain.
The equipment drives the refrigeration cycle through a fully enclosed Compressor and uses the environmentally friendly refrigerant R410a for refrigeration. The built-in circulation pump pumps the refrigerant out of the liquid storage tank, flows through the refrigeration system and is cooled down, and is transported to the external equipment (such as reactors, instruments, etc.) that needs to be cooled down through the external circulation interface. After taking away the heat, it returns to the liquid storage tank to form a closed circulation chill down loop, so as to achieve continuous and stable low temperature control.
Chemical field (atomic absorption, ICP\ ICP-MS, nuclear magnetic resonance, biological fermentation tank, chemical reactor, etc.), biological field, material field (electron microscopy, X-Rays diffraction, X-fluorescence, magnetron sputtering, vacuum coating machine, laser, etc.), Food processing, chemical industry, Universities & colleges, scientific research laboratories
International environmental refrigerant standards
1. Check whether the equipment Power supply voltage (220V, 50Hz) and environmental conditions (temperature 5~ 35 ℃, 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. Use the threaded connection (1/2) to connect the external circulation interface of the equipment to be chilled down correctly. 4. Turn on the power supply and turn on the power switch of the device. 5. Through the digital temperature display instrument to set the required temperature value (Temperature range -30~ RT ℃). 6. Start the circulating pump, observe the outlet pressure gauge, and adjust the pump pressure as needed. 7. The equipment starts to run refrigeration, and can be put into use after the temperature reaches the set value and stabilizes. 8. After use, turn off the circulating pump and power switch in sequence.
• Please ensure that the device operates at the allowable Ambient Temperature (5~ 35 ° C) and relative humidity (≤ 70%). • Please check the liquid level of the storage tank before use to ensure that the refrigerant is sufficient. • When connecting the external circulation pipeline, please ensure that the interface (1/2 thread) is firmly connected 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. • Please pay attention to safety when moving or handling equipment (weight 80kg). • The equipment has safety protection functions such as delay, overcurrent, overheating, etc. In case of abnormal alarm, please check in time.
