System Configuration & Types
CNG Mother Station
Direct pipeline connection interface designed for high-throughput tube-trailer filling and high-capacity vehicle refueling; features high-displacement multi-stage compressors (up to 2,000+ Nm³/h).
CNG Daughter Station
Tube-trailer supplied station configuration featuring rapid cascade unloading posts, booster compressors, and dual-hose mass-flow-metered dispensers for urban or off-pipeline locations.
CNG Standard Station
Direct grid pipeline feed combined with on-site storage cascades and medium-to-high capacity compression skids for standard retail and commercial fleet dispensing.
Mobile CNG Refueling Unit (MRU / Portable Station)
Containerized (20ft/40ft ISO framework) turnkey systems integrating hydraulic-drive compressors, storage cylinders, and dispensers on a single transportable skid.

Application Scenarios
Municipal Bus Depots & Logistics Fleets
High-frequency, fast-fill transit fueling islands operating on rigorous scheduled timetables.
Retail Public Gas Stations
Multi-dispenser highway and urban service stations requiring automated payment integration and simultaneous dual-side vehicle fueling.
Off-Grid Industrial & Mining Sites
Remote energy supply nodes utilizing mobile trailer-fed units where pipeline infrastructure is absent.
Pipeline Midstream Boosters & Daughter Nodes
Secondary distribution terminals transferring compressed natural gas from transmission mains to local distribution networks.
Selection Criteria & Engineering Checklist
Inlet-to-Outlet Pressure Ratio Analysis
Match compressor staging to lowest expected seasonal pipeline inlet pressures to prevent capacity starvation.
Flow Rate vs. Peak Hour Demand
Calculate vehicle fill frequency (e.g., 200 Nm³ per heavy-duty truck) against storage cascade volume to determine required compressor displacement (Nm³/h).
Duty Cycle & Thermal Management
Verify cooling water flow rates or ambient air-cooler capacities for continuous 100% duty cycle operation in high-ambient temperature regions.
Footprint & Plot Plan Constraints
Evaluate skid dimensions, safety clearance zones around CNG storage cascades, and explosion-proof electrical separation boundaries.
Manufacturing, Materials & Quality Control
Control Architecture Compatibility: Ensure PLC logic supports remote SCADA integration, automated fault logging, and unattended operation protocols.
Pressure Vessel Fabrication: Storage cascades and scrubber vessels manufactured from seamless alloy steel billets (ASTM A372 / EN 10083) subjected to 100% ultrasonic testing (UT) and magnetic particle inspection (MPI).
Frame & Structural Integrity: Structural steel skids engineered with finite element analysis (FEA) to withstand transit vibration, seismic loads, and dynamic compressor reciprocating forces.
Piping & Manifold Assembly: 316L stainless steel high-pressure tubing and manifolds, argon-arc TIG welded by certified ASME Section IX welders, followed by 1.5x design pressure hydrostatic testing and helium leak detection.
Factory Acceptance Testing (FAT): Every completed compressor skid undergoes a 4-hour full-load run test under simulated gas density conditions, measuring vibration velocity, bearing temperatures, and volumetric efficiency.
Customization & Engineering Support
Tailored Skid Layouts
Modular piping and electrical layouts adapted to strict plot boundaries or containerized ISO enclosures.
Power Supply Adaptation
Custom electrical configurations built for 380V/415V/480V, 50Hz/60Hz, 3-phase regional utility grids with variable frequency drive (VFD) integration.
Climatic Engineering
Integrated enclosure climate control featuring automatic louvers, explosion-proof electric space heaters, or heavy-duty glycol chillers for extreme ambient extremes.
Engineering Documentation Package
Complete submittal packages including P&ID schematics, hazardous area classification drawings, electrical loop diagrams, and ASME/PED compliance dossiers.
