AUTO-PURGER AP

This is the original AUTO-PURGER. It has solid-state
control and is ideal for larger systems, up to 1500 tons
(5300 kW) ammonia. This is two to three times the
air removal capacity of
the Armstrong purger.
With models available to
purge up to 24 points, the
AP features automatic
start-up with electronic
control. The purge cycles
c a n b e i n d i v i d u a l l y
adjusted to meet system
requirements. The AP
includes an automatic
w a t e r b u b b l e r . A n
optional NEMA 4 rated
enclosure is available.

AUTO-PURGER APM

A more compact ver sion of the original AP, the
AUTO-PURGER APM is ideal for medium-size systems,
up to 200 tons (700 kW). Like
the AP, the APM features
a u t o m a t i c s t a r t- u p w i t h
electronic control. Designed
for up to four purge points, an
electronic "brain" searches
for noncondensible gases
in the system and purges
at those points when air is
present. The APM includes an
automatic water bubbler and
comes standard with a NEMA
12,13 control cabinet. For use
with ammonia refrigeration
systems. Assembled, tested,
and ready to run.
Nonelectrical AUTO-PURGER (NEAP)
T h e n o n e l e c t r o n i c a l A U T O -
PURGER (NEAP) is ideal for small
systems, up to 100 tons (350
kW). The nonelectronical design
also makes the NEAP ideal for
explosion proof applications.
The simple design of the NEAP
