Control Panel Specifications
  • UL listed control panel has a NEMA 12 enclosure.
  • Externally operable circuit breakers with door interlocks, control circuit transformers with fused primary and secondary circuits, H-O-A switches and magnetic starters with three leg overload protection.
  • Touch screen monitor displays the hours of operation of each pump, settings of the system and indicates any faults.
  • Lighting on the H-O-A switches indicates which pump is running.
  • Audible and visual local alarms are included for all required alarms and manufacturer recommended alarms.
  • All control and alarm functions shall remain energized while any compressor in the system remains electrically online.

Vibration Isolation System
The compressor and motor is fully isolated from the package base by means of rubber mounts.

Air Receiver
  • AMSE construction.
  • Inside of the tank shall be double epoxy coated for rust protection.
  • Rated for a maximum 200 psig MWP service.
  • Equipped with pressure gauge, safety relief valve, three way bypass, sight glass and automatic electronic tank drain with manual override.

Dryer/Filter/Regulator System
  • NFPA 99 compliant dual desiccant air dryers with an integral, demand based, purge saving control system.
  • Equipped with two pre-filters, two after-filters, two pressure regulator valves, one dew point monitor, one CO monitor and multiple system safety valves.
  • Completely pre-piped and pre-wired to single point service connections.
  • There shall be two identical banks of air treatment equipment, piped in parallel and provided with valves to bypass either filter set for element replacement, maintenance and repair work while still treating medical compressed air through the other set.
Each bank consists of three stages:
-- 1st stage: prime efficiency coalescer with filtered differential pressure gauge and electric solenoid auto drain valve.
-- 2nd stage: desiccant heatless air dryer equipped with purge control.
-- 3rd stage: prime efficiency particulate afterfilter
