Z MED Medical Air System
4107 9022 67.00
oil system includes an oil sump, pump, oil filter,
bypass valve, drain connection, sight-glass and
cooler.
Intake Piping
The compressor has a factory piped intake with
one “hospital type” inlet air filter with flanged
connection for remote air intake. The inlet filter
removes dust from the incoming air through
cyclonic action and through an element. A
stainless steel intake flex connector with flanges
ships loose.
Discharge Piping
Each compressor module is equipped with
an integral air-cooled aftercooler, complete
with moisture separator and timed automatic
solenoid drain valve. The compressor discharge
line includes an external flex connector, internal
safety relief valve and check valve. The external
flex connector is braided stainless steel, type
304. For ZR water-cooled systems, a water shut-
off valve ships loose.
Isolation System
The compressor and motor shall be fully
isolated from the main compressor module
base by means of a heavy isolation system for a
minimum of 95% isolation efficiency.
Dryer/Control Module
The dryer/control module shall include a central
control system to control multiple compressors
and a duplexed desiccant drying system with
dew point hygrometer/ CO transmitters. Each
dryer includes an inlet filter, final line filters
and regulators. All of the above shall be factory
piped and wired in accordance with NFPA 99 and
include valving to allow complete air receiver
bypass, and air sampling port.
Dryer/Filter/Regulator System
Each desiccant dryer must be individually sized
for peak calculated demand and capable of
producing a -40°F (-40°C) pressure dew point.
Dryer purge flow shall be minimized through
an integral demand based purge saving control
system. The inlet to each dryer shall include a
combination particulate and coalescing filter
with an automatic drain. The duplexed final
line filters consist of a 1 micron particulate filter
and one active carbon filter, duplexed final line
regulators, single oil indicator and duplexed
safety relief valves shall be factory mounted
and piped. All filters shall have element change
indicators.
Central Control System
The mounted and wired central control system
shall be NEMA 12, U.L. labeled and rated
for 115V single phase electrical service. The
control system shall provide automatic lead/
lag sequencing, visual and audible reserve unit
alarm with isolated contacts for remote alarm.
Automatic alternation of all compressors based
on a first-on/first-off principle with provisions for
simultaneous operation if required, automatic
activation of reserve unit if required, visual and
audible alarm indication for high discharge air
temperature shutdown with isolated contacts
for remote alarm shall be included.
Dew Point / CO Transmitters
The dryer/control module shall incorporate
a dew point and a CO transmitter that are
mounted, pre-piped, and wired. Dew point and
CO conditions will be displayed on the central
control system. The dew point transmitter
probe shall be the ceramic type sensor. The
system accuracy shall be a minimum of ± 2°C for
dew point and ± 2 ppm (at 10 ppm) for carbon
monoxide. Dew point alarm shall be factory set
at 36°F (2°C) per NFPA 99, and the CO alarm shall
be factory set at 10 ppm. Both set points shall
be field adjustable. High CO and high dew point
conditions shall be indicated with visual and
audible alarms.
Air Receiver Module
The vertical air receiver shall be ASME Coded,
National Board Certified, galvanized, rated for a
minimum 150 psig design pressure and include
a liquid level sight glass, pressure gauge, safety
relief valve, manual drain valve and an automatic
solenoid drain valve. “ZR” water cooled systems
will include a high level condensate sensor.
