Compared with traditional steel cylinders, Dewar bottles have the advantages of large storage capacity and low loss (Dura-Cyl180MP Dura-Cyl180MP Duura-Cyl180MP Duwa bottle has a volume of about 0.2 square meters and a height of 1.6 meters. The net volume is 196 liters, and the gas The gas after being converted into gas reaches 146 cubic meters. Customers can completely use up the bottled gas without any waste. Conventional standard cylinders require 25 to fill a 146MPa gas cylinder. However, when the current cylinder filling pressure is 15MPa, due to the temperature drop, The pressure inside the cylinder is between 13-13.5MPa. At the same time, the cylinder needs to leave residual air. The actual use of each cylinder by the user is about 5.2~5.5MPa. From wiring to starting use, only one person needs to operate, and the whole process takes about 3 minutes.
