PURGING

Touchpad controller with
automatic safety features and
status display

The hold feature preserves system
pressure, conserves purge air and
saves energy by automatically closing
the purge exhaust valve when the
compressor unloads or is on standby. It
resumes the cycle when compressor
flow returns.
The cycle monitor with LED and
remote contact allows immediate
notification of any disruption of the
operation cycle.
The controller also features a membrane
panel housed in a NEMA 4X
enclosure which clearly displays dryer
operation with LED indicators for each
step in the cycle sequence.
