Climate Control Duplex
Basic Alternator Package
All Powerex duplex air compressors may be ordered with a
simplified line voltage basic alternator package. The basic
alternator package consists of an alternating coil and two
magnetic motor starters. Motor starters are selected and
wired for intended input voltage and are furnished with
properly sized overload heaters.
Automatic Tank Drain
Powerex air compressors may be ordered with a manual
or electric type automatic tank drain. A manual drain
attachment is furnished with each unit.
Vibration Dampening Pads
Waffle type design vibration pads are provided as standard
equipment.
Operation
Factory calibrated DPST pressure switches provide lead and lag
settings. When using an alternator-starter package, the lead
switch energizes the alternator and the alternator activates
the compressor that was on standby during the previous cycle.
If the demand exceeds the capacity of one compressor, the lag
switch will cause both compressors to run simultaneously. Upon
failure of either compressor, the lag switch will continue to
activate the workable compressor.
Single-phase motors (3/4 HP & 1 HP) have built-in overload
protection with manual reset. Three-phase motors require
a magnetic starter and three overload heaters. Heaters are
included with three-phase compressors that have a factory
mounted alternator.
NOTE:
All pump models operate turning clockwise opposite
the motor shaft / pump flywheel / belt guard side of the unit.
Improper rotation will cause oil to spray out of the breather
vent opening.
