Compressor System Application
Universal Air & Gas Products Corporation (UAPC) has decades of successful experience in turn-key, natural gas fuel system design and construction. Gas compression, storage, dispensing, regulation and controls are all available from UAPC. Similar expertise is applied to government, military and industry applications. These applications include natural gas (NGV) systems built to virtually any USA or international standard.

The services that we provide for the production of natural gas refueling stations or component systems are:
  • Consulting
  • Station design/engineering services
  • In house CAD design capabilities
  • Standard and custom designed compression packages
  • Supply of state of the art fuel dispensing systems
  • Supply of ASME & DOT gas storage systems
  • Supply of card readers
  • Construction management
Certified field service technicians and engineers support UAPC systems during installation and startup. As needed or long-term maintenance agreements are also available, which provide for routine or comprehensive technical site supervision. Documentation packages are extensive. This facilitates detailed maintenance, appropriate
