Bid Spec – Double Fill Station with Controls

Containment Fill Station Specification for containment fill station with control panel. The fill station shall be designed for a maximum input pressure of 6000 PSI.   The fill station shall be constructed of 1/4” steel plate and steel tube.   Fill station shall be finished with a highly durable powder coat. The fill station shall fully enclose two SCBA or SCUBA cylinders while being filled.  Venting shall be provided to allow air from a ruptured cylinder to escape the fill station while being directed away from the fill station operator. The fill station door shall be precision balanced to allow opening and closing with minimal operator effort.  A safety interlock shall be provided that will prevent refilling of cylinders unless the fill station door is securely closed and locked.  Each fill pocket shall be lined with protective material to prevent damage to cylinders. Two fill hoses shall be located within the fill station.   Each hose shall have a bleed valve and a fill adapter of the buyers choice. Control Panel The fill station shall be equipped with a cascade control panel that provides the following standard features:
  • 4 Cascade bank controls valves
  • 4 Cascade bank pressure gauges 2 1/2” liquid filled
  • Adjustable fill pressure regulator
  • Output pressure gauge 4” liquid filled
  • 2 cylinder fill valves
  • 1 auxiliary fill valve
  • 4 connecting hoses from cascade bottles up to 10 ft in length
Compressor: The compressor shall have a maximum working pressure of no less than 6000 PSI and a minimum charge rate of no less than 8 CFM.   The compressor shall be air-cooled and oil lubricated, of a  3 stage reciprocating design.   The crankshaft shall be supported at both ends by high performance ball or roller bearings.   The final stage piston must be of a ringed design.   Each cylinder shall be directly bathed with cooling air from the compressor's integrated cooling fan. An intercooler shall be present between each stage of the compressor and an aftercooler after the final stage of compression.   A cool-down cycle shall not be required prior to stopping to compressor. Moisture separators shall be present after each stage of compression with the exception of the first compression stage.  The compressor shall be equipped with an automatic condensate drain system.   The automatic drain system shall drain the accumulated moisture from each moisture separator at a preset interval specified by the manufacturer.   An exhaust muffler and condensate reservoir shall be supplied for the automatic drain system. The compressor shall be oil lubricated and have a crankcase oil capacity of no less than 2 quarts.   A highly visible sight glass shall be included to check the oil level. The compressor shall include a replaceable inlet particulate filter element. The compressor shall be powered by a single phase electric motor with a minimum rating of 7.5 HP.  The compressor block and electric motor shall be vibration isolated from the compressor's frame.  Power from the motor shall be transmitted to the compressor by means of a v-belt drive system. Compressor and motor shall be mounted in a vertical configuration. The compressor shall be equipped with the following controls:
  • Magnetic contactor with thermal overload
  • Push button start / stop switches
  • Pressure stop switch
  • electronic carbon monoxide monitor
The compressor shall be equipped with the following gauges / indicators:
  • Liquid filled pressure gauge after each stage of compression
  • Non-resettable hour meter
  • Digital carbon monoxide level display
The compressor shall be equipped with a purification system that will provide CGA Grade E breathing air.  The purification system must have a working pressure of 6000 PSI.   The system shall feature a replaceable filter cartridge that is capable of filtering 24,000 Cu Ft of air @ 80° F before requiring replacement.   A back-pressure regulator shall be installed downstream of the purification system to maintain positive pressure in the purification housing. The compressor shall be installed in an enclosed sound suppressing cabinet. Cabinet with have lift off panels for ease of accessing the compressor and components for service and/or maintenance. Cabinet will include labels designating the function of all mounted gauges and controls. Cabinet will be mounted on adjustable rubberized feet. Cabinet shall have a foot print no greater than 36” by 24”.
