Time Fill: When you refill a fleet of vehicles at a central location simultaneously – a compressor fills all the vehicles via hose pole. Time fill hose assembles come in single, dual or 4 hose versions and are normally not metered. Combination: As its name implies, this system blends both quick and time fill layouts. The appropriate fueling method is determined by fleet and customer needs. While facility size and design may vary, the same basic features are usually incorporated into each layout. Compressor recommendations for natural gas fueling Charger series compressors offer a compact, vertical design, water cooled unit designed specifically for small and medium sized natural gas fueling stations. For higher volume needs, the horizontal, two throw, balance opposed Century series or the single throw, inline Slimline series are recommended. The Slimline compressor is balanced-opposed and water cooled, and available in both electric motor and engine drive configurations.

Cascades are available as either DOT bottles or ASME vessels, depending upon what storage capacity is needed. Cascades can also be connected together to increase storage. The priority/emergency shutdown (ESD) panel redirects gas from the compressor to the appropriate fueling “station” and isolates storage cascades should an emergency occur. Gas dryers are used to remove water vapor from the gas to meet local “dew point” conditions.
