CNG STORAGE CASCADE is one of the key components in a CNG Refueling Station. It consists of CNG cylinders, steel frame, valves, pressure gauge, manifolds and high-pressure fittings. Usually, the cylinders are arranged in a three-bank cascade, meaning that there is a low-pressure vessel, a mid-pressure vessel and s high-pressure vessel. Priority sequence control panel is also available according to customers' requirements for the CNG Refueling Station. The total amount of storage will be depending on the number of vehicles, the amount of gas each vehicle requires, and the time frame in which the vehicles need to be filled. The design code of storage cylinders is usually ISO or ASME standard, and 250 bar operation pressure are widely used so far.

CNG HPU Hydraulic Power Unit

As a patented product of CIMC ENRIC, the HPU CNG Daughter Filling Station will be fed natural gas by a CNG trailer, and no need to rely on a natural gas pipeline network. It uses high pressure hydraulic pump to inject the special fluid into the high pressure CNG Trailer to push the CNG gas out of each tube. And then, the high pressure CNG is injected into the NGV cylinders by CNG dispenser in the station. The whole system is constituted by three parts, i.e, daughter station skid, CNG trailer and gas dispenser, and requires no more other pressure boost equipment.
