Integrated Compressor Assembly

GTC CNG compressors are delivered as fully assembled skid-mounted packages, ensuring fast installation and reduced on-site work.

• Compressor body, cabling, terminal boxes, and operator panels are mounted on a single skid
• Control systems can be:

○ Integrated directly on the compressor frame, or

○ Installed in stand-alone control cabinets, depending on customer requirements

• This modular approach improves flexibility, simplifies commissioning, and minimizes installation risks

Advanced Compressor Control Systems

GTC’s CNG compressors are equipped with sophisticated electronic control systems, designed and maintained by highly qualified, electrical-based programming teams.

• Over 60% of GTC compressors operate with advanced electronic controls
• Systems include:

○ Programmable Logic Controllers (PLC)

○ Display panels and annunciators

○ Comprehensive pressure and operational logic

• These control systems ensure stable operation, precise pressure regulation, and enhanced safety under all operating conditions
