Overview
The DL30-1000 cycle 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. The equipment adopts a closed circulation system to effectively prevent the evaporation of the refrigerant and is equipped with a variety of safety protection functions to ensure long-term stable operation.
Features
1. Adopt brand fully enclosed Compressor, low noise and high Reliability.
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 refrigerant volatilization and pollution.
4. Install an filtrating device in the circulation pipeline to prevent blockage.
5. Adopt a fluorine-free green refrigerant (R410a) that does not contain chlorofluorocarbons, meeting international environmental standards.
6. Small size and beautiful appearance.
7. Equipped with a liquid level display tube, it can monitor the liquid level of the built-in liquid storage tank.
8. The refrigerant outlet is equipped with a pressure gauge to display the pressure.
9. Specification models to meet different needs.
10. The left and right side panels are easy to disassemble and easy to maintain.
Principle
The equipment drives the refrigeration cycle through a fully enclosed Compressor, using the environmentally friendly refrigerant R410a for heat exchange and taking the heat away to achieve cooling. The built-in circulation pump pumps the chilled down refrigerant from the liquid storage tank and transports it to the experimental equipment or reactor that needs to be chilled down through the external circulation interface. The heat-absorbing refrigerant is returned to the equipment to be chilled down again, forming a closed circulation chill down circuit.
Applications
Chemical, biological, physical testing experiments, Food processing, Chemical industry, Universities & colleges laboratories, scientific research laboratories, 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
Standards
International environmental refrigerant standards
Steps
1. Check the Power supply voltage (220V, 50Hz) and environmental conditions (Temperature 5~ 35 ℃, Humidity ≤ 70%).
2. Confirm that the refrigerant level in the liquid storage tank is sufficient through the liquid level display tube.
3. Connect the external circulation interface (1/2 thread) of the equipment to be chilled down correctly.
4. Turn on the power supply and set the required temperature according to the digital temperature display instrument (Temperature range -30~ RT ℃).
5. Start the equipment, observe the pressure gauge to display the refrigerant pressure, and ensure smooth circulation through the filtrate device.
6. During the operation of the equipment, monitor the temperature Stability （ +/- 2 ° C) and operating status.
7. After use, turn off the equipment according to the prescribed procedures.
Notice
• Please ensure that the device operates at the allowable Ambient Temperature (5~ 35 ° C) and relative humidity (≤ 70%).
• Please check the liquid level 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.
• The equipment is equipped with safety protection functions such as delay, overcurrent, and overheating. Please check in time if there is any abnormality.
• Regularly check the filtrating device of the circulating pipeline to prevent blockage from affecting the circulation.
• During maintenance, the left and right side panels can be removed, but they need to be carried out in a power-off state.
• Please use a refrigerant without fluorine (R410a) that meets international environmental standards.
