Overview
The cold-dry air generator (model LC-LGA-3) is an air source specially designed for Gas Chromatograph, which can replace high voltage cylinders and make analysis work safer and more convenient. The instrument has secondary overvoltage protection and overtemperature automatic control device, which automatically cuts off power when the pressure exceeds the limit or the Compressor shell temperature reaches 80 ° C, which is safe and reliable; the normal pressure start is used to extend the life of the Compressor. The gas purification system combines cold-drying technology and activated carbon to ensure that the gas is pure, and the two-stage voltage regulation design improves the gas source Stability.
Features
The 1.7-inch color screen monitors the cold-drying temperature, output pressure, tank pressure, cold-drying and Compressor status in real time.
2. The output and pressure in the tank are displayed by precision Sensor digital, replacing the traditional pointer meter.
3. Cold dry cyclone cooling technology, low gas temperature, daily maintenance-free.
4. The output gas temperature is low, the dew point is better than -70 ℃, and the water content is low.
5. With the boot time and cumulative Working time memory function.
6. With overpressure, overcurrent, overheating three fully automatic protection.
7. Two-stage voltage regulation, output pressure can be adjusted externally, easy to operate.
8. Easy to operate, gas is produced immediately after startup, and the pressure is stable. It can simultaneously supply gas to the Gas Chromatograph and nitrogen generator.
9. Adopt 8L mg aluminum alloy gas storage tank, which is resistant to high voltage and large gas storage capacity, reduces the number of starts and stops, and prolongs the life of the Compressor.
10. Equipped with an automatic drainage valve, the circulating drainage time can be set to achieve fully automatic drainage.
11. Gas Purification System integration activated carbon and cold drying device to remove impurities and moisture without additional purification tube.
12. It can replace traditional high voltage air cylinders and achieve laboratory instrumentation.
Principle
The instrument generates compressed air through the Compressor, which is cooled by a cyclone to reduce the gas temperature and water content, and then removes impurities and water through an activated carbon purification device to ensure the purity of the output gas. The gas circuit adopts a two-stage voltage regulation design to improve the Stability of the output pressure, and finally provides a stable and clean air source for Gas Chromatograph and other equipment.
Applications
Gas Chromatograph Air Source, Laboratory Analytical Instrument Supply
Steps
Connect the power supply (220V 50Hz).
2. Turn on the power switch, and the instrument automatically starts gas production.
3. Set the required output pressure (0 to 0.4MPa) through an external regulating valve.
4. Monitor the running status through the screen, and set the automatic drainage time.
Notice
• The working environment should be kept at 10 ℃~ 40 ℃, Humidity ≤ 85%.
• Make sure to use a gas line with an outer diameter of 3mm and an M8 × 1 nut connector.
• The instrument has an automatic protection function, but it is still necessary to avoid forced use under overpressure, overcurrent or overheating conditions.
• Regularly check whether the automatic drain valve function is normal.
• Net weight of the instrument is 30kg when moving or maintaining.
