CONTROL PANEL AND PACKAGE INSTRUMENTATION

Standard Panel - Annunciator Based

  • Console control panel
  • Panel instrumentation for all operating functions
  • Steel panel cabinet
  • Altronic DD-40NTV-0 annunciator
  • Engine JW Temperature swichgage

DISCRETE INPUTS - CLASS B1

  • Low pressure - suction
  • Low pressure - discharge
  • High pressure - suction
  • Loss of speed signal (integral to annunciator) - signal from magnetic pick-up

CLASS B2

  • Low pressure - engine oil
  • Low pressure - compressor oil

CLASS A

  • High pressure - discharge
  • High temp - compressor discharge
  • High temp - engine jacket water
  • High level - scrubber
  • Low level - engine oil
  • Low level - compressor oil
  • Emergency stop - local – push button on panel
  • Overspeed (integral to annunciator) - signal from magnetic pick-up

ADDITIONAL CONTROL PANEL OUTPUTS

  • Mode selector switch - idle / manual / auto
  • Manual speed potentiometer
  • Unit panel power switch - off/on - on panel insert.

PACKAGE FEATURES

  • 3/8" plate structural skid with 35 gallons fluid containment capacity
  • CNC machined skid brackets and details for perfect fit and interchangeability
  • Suction control valve with positive shut-off system when compressor shuts down
  • ASME code scrubber/blowcase with up to 25-35 bbl/day fluid handling capability with the optional ability to re-inject the fluids into the discharge gas stream. System designed for maximum efficiency adapting to fluctuating discharge pressure conditions with increased discharge pressure only when needed for the dump cycle. Engine jacket water heat trace system prevents liquid from freezing in blow case.
  • Process piping constructed with S 80 A106 grade B seamless carbon steel pipe with carbon content < .43%
    30, 60 and 90 day service schedule based on load, RPM and gas composition
  • 5 gallon oil day tank and automatic level controllers provides make-up oil to both driver and compressor.
  • Optional custom powder coated trailer with single axle electric brake system and integrated leveling jacks eliminates site preparation and provides an easy method of transporting compressor.
  • Optional low suction pressure make-up system prevents unnecessary shut-downs when gas flow rate fluctuates. System also prevents vacuum operation if desired.
  • Optional package bypass system allows gas production to continue if the compressor shuts down.

UNIT PAINT

  • Sertco HIS Industrial Coating paint details
  • Commercial Sandblast
  • Primer – 1 coat of red oxide high solid polyamide epoxy primer to 5.0 mils DFT
  • Top coat – 2 coats acrylic, aliphatic polyurethane in any color combination to 3-4 mils DFT
