Turnkey CNG Fueling Station - ANGI 50 HP Compressor System

Compressed Natural Gas (CNG) fueling infrastructure continues to expand as fleet operators, municipalities, and industrial companies seek lower-emission fuel solutions and long-term cost stability. A properly designed CNG fueling station requires compression, gas drying, pressure management, and electrical controls to safely compress pipeline natural gas into high-pressure storage or directly into natural gas vehicles.

One option that simplifies deployment is a turnkey CNG compression system, where the primary equipment components are already matched and assembled into an integrated package.

Gas Equipment 4 Sale currently has a complete CNG fueling station package available, built around an ANGI natural gas compressor system capable of compressing natural gas from 9 PSI inlet pressure up to 5,000 PSI discharge pressure at approximately 75 SCFM.

What Is a Turnkey CNG Fueling Station?

A CNG fueling station compresses natural gas from pipeline pressure into high-pressure storage or directly into vehicle tanks. These systems allow fleets to operate vehicles powered by compressed natural gas instead of gasoline or diesel.

Most fueling stations require several core systems to function properly:

• Natural gas compressor

• Gas drying and filtration equipment

• Priority fill or cascade control systems

• Electrical power and motor control equipment

• Storage or dispensing equipment

When these components are engineered to operate together, the result is a complete fueling system capable of compressing natural gas and delivering it at vehicle fueling pressures.

According to the U.S. Department of Energy’s Alternative Fuels Data Center, compressed natural gas is widely used in transit fleets, refuse trucks, delivery fleets, and municipal vehicles due to its lower emissions and fuel cost advantages.

Why Turnkey CNG Compression Systems Matter

Building a CNG station from individual components requires significant engineering coordination. Compressors, dryers, and control systems must all be sized correctly to operate safely at high pressure.

Turnkey packages simplify this process.

Key advantages include:

Faster deployment

Operators can deploy a fueling system much faster when the major components are already matched.

Reduced engineering complexity

Systems designed as integrated packages reduce compatibility issues between compressors, dryers, and electrical controls.

Lower installation time

Skid-mounted systems simplify installation compared to assembling individual components from multiple suppliers.

System Overview: ANGI Natural Gas Compression Package

The core of this fueling system is an ANGI natural gas compressor package, a widely used compressor platform within CNG fueling infrastructure.

System specifications include:

Model: ANGI NG-050-E/S-4-Z

Motor: 50 HP

Capacity: 75 SCFM

Inlet Pressure: 9 PSI

Maximum Discharge Pressure: 5,000 PSI

The compressor is skid-mounted and designed for continuous duty CNG compression applications.

The unit currently has approximately 14,000 hours of operation, and all scheduled service and maintenance have been performed according to manufacturer recommendations. Equipment documentation including service records, schematics, and manuals is available.

Additionally, all pressure relief valves were recertified in August 2025, which is an important safety requirement in high-pressure gas systems.

Moisture Control: ANGI Natural Gas Dryer System

Moisture removal is critical in compressed natural gas systems. If moisture remains in the gas stream, it can damage compressors, create corrosion, and reduce the efficiency of downstream storage systems.

This package includes an ANGI natural gas dryer skid designed to remove moisture and contaminants before compression and storage.

The dryer skid includes:

• Desiccant drying towers

• Integrated control panel

• Electric motor-driven cooling system

• Fully plumbed skid-mounted configuration

Skid mounting simplifies integration into a full CNG fueling station.

Priority Fill Panel for Fleet Fueling Operations

Efficient fueling stations rely on priority fill panels to control gas distribution between vehicles and storage systems.

This system includes an ANGI PR-100 priority fill panel designed to manage gas flow within the fueling system.

The panel includes:

• High-pressure regulators

• Manual shut-off valves

• Pressure gauges

• Rated pressure up to 5,000 PSI

Priority fill panels allow fleets to fuel vehicles efficiently while managing pressure across the storage system.

Electrical Controls and Power Management

The package also includes a dual 50 HP motor starter panel equipped with a Hevi-Duty transformer.

Electrical specifications include:

Voltage: 480V / 3-Phase / 60Hz

Full Load Amps: 162.4A

Transformer Model: Hevi-Duty HS5F5AS

Power Rating: 5 kVA

Enclosure: UL Type 3R Outdoor Rated

Industrial control panels like this provide the power management and motor control required for safe compressor operation.

Why Used CNG Compressor Systems Are in High Demand

New CNG compression equipment can often involve long lead times depending on compressor manufacturer availability and system size. In some cases, new equipment lead times can exceed six months to a year.

Because of these delays, many operators evaluate used or surplus CNG compressor systems that can be deployed more quickly while still providing reliable compression performance.

Turnkey systems that already include compressors, dryers, and control panels can significantly reduce project timelines for operators planning new fueling infrastructure.

Inspection and Shipping

Pre-purchase inspections are welcome during normal business hours by appointment.

Buyers traveling to inspect the equipment in person can coordinate scheduling in advance.

Shipping logistics assistance is available, and loading services can be provided for equipment located at our yard for units weighing up to 15,000 pounds, when scheduled in advance.
