NFPA Quadruplex SCD Modular Stack Mount
NFPA Quadruplex SCD Modular Stack Mount

NFPA Scroll Compressors

The quadruplex modular stacking configuration consists of two compressors mounted on top of one another on both sides of the receiver tank. This modular or field separable design allows for ease of shipment and handling on site.

  • Please click the purple "ordering guide" icon above to download our sizing guide for Source equipment.

Control Panel

  • UL listed control panel in a NEMA 12 enclosure with a 5.7" Touch Screen Display
  • Manual reset for all alarms
  • All control and alarm functions shall remain energized while any pump in the system remains electrically online
  • Ethernet connectivity with embedded webpage for remote monitoring, password protected for remote adjustment of all operating parameters

Air Compressor

  • V-belt driven Oil-Less Rotary Scroll, single stage, air-cooled construction with absolutely no oil needed for operation (Available in 120 or 145 psi configuration)
  • A-Frame, stackable scroll allowing two pumps to run simultaneously with smaller footprint allowing for compact design
  • 3,600 RPM, premium efficiency motor
  • Means of removal of the compressor for service or replacement without interruption to the system

Air Receiver

  • ASME certified
  • Rated for a minimum of 200 psig design pressure
  • Inside of the receiver consists of a two-part epoxy coating providing rust protection equal or better than that achieved by galvanizing
  • Three-valve bypass for service or replacement without interruption to the system

Dryer/Filter/Regulator System

  • Integral air treatment system with purge saving feature, NFPA 99 compliant assembly featuring dual desiccant air dryers, dual pre-filters, after-filters, pressure regulator valves, dew point monitor, CO monitor and system safety valves
  • Completely pre-piped and pre-wired to single-point service connections

Each bank consists of three stages:

  • Stage 1: Prime efficiency coalescer with filtered, differential pressure gauge
  • Stage 2: Desiccant heatless air dryer, equipped with purge control capable of attaining pressure dew point of -40ºF. The dry compressed air is discharged from the "online" tower into the 3rd stage
  • Stage 3: Prime efficiency particulate after filter with manual drain differential pressure gauge along with downstream pressure regulators that will maintain constant discharge pressure of 50 psig (field adjustable)
