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
