Product Description

Skid-Mounted CNG Refueling Station with Compressor Storage  Dispenser System

 

This skid-mounted CNG refueling station is designed for natural gas vehicle fueling and gas distribution applications. The system integrates compressor, cascade storage, and dispenser into one compact unit.

Skid-mounted CNG Daughter Station is a complete integrated refueling system mainly used for natural gas vehicle (NGV) refueling. It takes high-pressure CNG from a transport trailer as the gas source, and realizes pressure regulation, compression, storage, sequencing and refueling through an integrated skid structure. It is widely used in bus fleets, logistics parks, taxi stations, mining areas, construction sites and other places without fixed pipeline gas supply.
 

The CNG substation integrated compressor consists of the main units such as the gas unloading column, gas filter, compressor, oil and gas cooling system, gas cylinder group, and gas dispenser, which are integrated into a rainproof and noise-reducing box through valve pipes. The compressor adopts a hydraulic reciprocating double-acting force structure design and is equipped with a piston position sensing system. The motor drives the hydraulic oil pump to supply oil, and the integrated reversing system allows the hydraulic oil to continuously push the piston to reciprocate to compress the natural gas. The compressor adopts a two-stage compression form, and the unit is cooled by water circulation and air cooling. The compressor uses a PLC control cabinet to fully automatically control the unit, which has the advantages of high automation, simple operation, safe and reliable operation, and convenient maintenance. The unit is skid-mounted and has achieved a completely unattended mode.
