Overview
DLSB-20/30 Cryogenic coolant circulating pump is a refrigeration equipment produced by GREATWALL. It uses Compressor refrigeration and conveys cold source through circulation pump, which can provide chill down for testtubes, reaction bottles, etc., to meet the conditions of low temperature reaction or storage. The equipment can also be combined with a variety of instruments to form a supporting device.
Features
1. Large capacity open bath and external circulation system, can be used as a freezer, but also to provide external chilling down liquid.
2. With key input and digital display, the operation is intuitive and convenient.
3. Key components such as refrigeration Compressors adopt international brands such as the United States, Germany and France, with high Reliability and good efficiency.
4. The circulation system adopts 304 stainless steel and polymer anti-corrosion material, which has the characteristics of anti-rust, anti-corrosion and anti-low temperature liquid pollution.
Principle
The equipment reduces the temperature of the chilled down liquid through the Compressor refrigeration system, and then uses the built-in circulation pump to pump out the chilled down liquid, and conveys it to the equipment that needs to be chilled down through the external circulation interface or directly chills down the experimental vessel in its large-capacity liquid storage tank, thereby providing a stable low temperature environment.
Applications
Chill down testtube, reaction bottle and other experimental utensils, Encasement machine, printing press, low temperature testing machine, spraying device, freezing fixture, low temperature mold, precision grinding, discharge processing device, wafer cleaning device, etching machine, laser chill down, Rotary evaporator, vacuum drying oven, circulating water multi-purpose vacuum pump, etc
Standards
Safety protection meets delay, leakage, overcurrent and overheating protection standards
Steps
Place the device under allowable environmental conditions (temperature 5~ 25 ° C, Humidity ≤ 70%) and connect the power supply (220V +/- 10%, 50Hz).
2. Add an appropriate amount of chilling down medium to the reservoir.
3. Press the button to set the required temperature (range -30 to RT ° C).
4. Start the equipment, the Compressor starts to cool, and the circulating pump starts to work.
5. You can put the utensils that need to be chilled down into the reservoir, or connect the external equipment through the external circulation interface (thread connection: 1/2 ") to chill down.
6. After use, turn off the power of the device.
Notice
• Please ensure that the Operating Environment temperature is between 5 and 25 ° C, and the relative humidity is ≤ 70%.
• Power supply voltage 220V +/- 10%, Frequency 50Hz.
• The liquid storage tank can hold up to 5000ml flask (need to be equipped by yourself), please pay attention to the capacity when using it.
The equipment has safety protection functions such as delay, leakage, overcurrent, and overheating, but it still needs to be operated in a standardized manner.
• When connecting external circulation, please note that the interface size is 1/2 "thread.
The cooling capacity of the equipment decreases as the temperature decreases, so pay attention to the actual cooling capacity at the corresponding temperature.
