Components
Oil-less Scroll Compressor Pumps
Powerex laboratory open scroll systems are designed to supply
connuous oil-free air by using the most advanced scroll technology.
The Powerex scroll compressor oers a dynamically balanced air
end which insures vibraon-free operaon. The rotary design permits
a connuous 100% duty cycle. No oil separaon, oil ltraon, or inlet
valves are required on the Powerex Scroll unit. Each compressor
shall be belt driven oil-less rotary scroll single stage, air-cooled
construcon with absolutely no oil needed for operaon. Direct drive
compressors shall not be used. The rotary design shall not require any
inlet or exhaust valves and shall be rated for 100% connuous duty.
Systems consist of mulple compressor pumps that are automacally
controlled and alternated to equalize usage and wear.
The Powerex oil-less rotary scroll air compressor is based on the
theory of scroll compression. A scroll is a free-standing, intricate
spiral bounded on one side by a solid, at plane or base. A scroll set,
the basic compression element of a scroll compressor, is made up
of two idencal spirals which form right and le hand parts. One of
these scroll components is indexed or phased 180° with respect to
the other so the scrolls can mesh.
Crescent-shaped gas pockets are formed and bounded by the spirals
and the base plate of both scrolls. As the moving scroll is orbited
around the xed scroll, the pockets formed by the meshed scrolls
follow the spiral toward the center and diminish in size. The moving
scroll is prevented from rotang during this process so that the 180°
phase relaonship of the scrolls is maintained. The compressor’s inlet
is at the outer boundary of the scrolls. The entering gas is trapped in
two completely opposite gas pockets and compressed as the pockets
move toward the center. The compressed gas is discharged through
the outlet at the center of the xed scroll so no valves are needed.
Each compressor shall have exible connectors on intake and
discharge, an electric drive motor, a discharge check valve, an air-
cooled aercooler and a high discharge temperature shut down
switch. Each compressor module shall have an isolaon valve and a
moisture separator with automac drain.
The scroll pump is driven by a three phase electric motor and a dual
V-belt drive.
The system includes an aer cooler for each pump and condensate
separators connected to electric mer drain valves. For NFPA99
systems, duplex, isolatable mer drains are installed. Each pump
module or stack of two pumps for 10 HP models is equipped with
an isolaon valve so that the pump or module may be removed for
service and the valve closed leaving the system operable with paral
capacity. (If the valve is used to isolate the system while a person is
working or risk of injury exists, appropriate energy lock out tag out
procedures must be employed.)
Controls
The disconnects and protecon devices in the Powerex control
system are for the motor branch circuits, accessory supply circuits and
for the control circuit only. The controls on the Powerex Laboratory
Open Scroll System do not include a service disconnect and circuit
protecon for the supply circuit. Selecon and installaon of these
items must be provided in compliance to local and naonal codes in
accordance with each facility’s need.
The PLC automacally alternates the lead designaon and brings
on lag pumps as needed, equalizing run me on the pumps in the
system. The touch screen HMI (Human Machine Interface) panel on
the front allows operaon and monitoring of the system. The touch
screen provides the user with displays showing the operang status
and allows the user to access features of the control system. The
control panel also allows communicaon using the BACnet® protocol.
The control panel includes Hand-O-Auto selector switches for
each pump so that a pump can be held on (or o). This can be useful
if maintenance or diagnosc procedures are being performed.
The transformer is sized for the loads imposed by the Powerex
factory controls and should not be ulized for any other purpose.
Premium control panels ulize a backup transformer with a reserve
transformer in use alarm.
Local alarms are provided for low pressure and general fault
condions. The general fault alarm includes high temperature,
reserve transformer in use, motor overload and reserve pump in use
(when specied). The wiring connecon point for the alarms is on the
terminal strip in the control panel box, with good condions being
contacts closed. (If a wire connecon is lost, the result is an alarm.)
Receiver Tank
The ASME, Naonal Board registered air receiver is provided in sizes
from 200 to 240 gallons. Each receiver is rated at 200 psig working
pressure. Receivers are provided with sight gauge, moisture drain
(manual and no-loss electric), and internal lining to prevent corrosion.
The system receiver tank with bypass valves and duplex twin tower
desiccant dryers are sized to provide adequate air storage and provide
a pressure dew point of –40°F for laboratory systems with one dryer
operang. Medical systems are not intended to operate with both
dryers simultaneously. Doing so will result in back ow into one of
the regulators and leakage of air from that device. Laboratory systems
have valves to allow both dryers to operate if needed.
The receiver tank is equipped with an electric mer drain that is
powered from the main control panel. The drain has a manual test
feature. The automac acon of the drain will be conrmed by the
lack of water accumulaon.
Never drill holes in, or perform any welding on
receiver tanks (unless qualied by ASME to do
so) or use them beyond the rated pressure sengs. Never mount other
machinery or equipment on receivers.
Air Dryer (Desiccant)
The regenerave desiccant consists of two (dual) towers lled with
desiccant. Each tower is switched on and o stream, alternang the
air system stream and then being regenerated. Dry purge air pulls
moisture from the desiccant and carries the moisture out of the
system. The medical system duplex twin tower desiccant dryers have

isolaon valves and each dryer has a pre-lter to remove water and
parculates, and an aer lter. Dierenal pressure indicators show
when the elements need to be replaced.
Lab system dryers are installed with automac switching valves and
check valves that allow the oine dryer to be ulized when system
ow requires the extra drying capacity. The control panel selector
switch designates the lead/lag status of the dryers.
Dew Point Monitor
The Powerex Dew Point Monitor provides indicaon of dew point
temperature. Its microprocessor is controlled with alarm and self-
calibraon sensor.
Regenerave dryers paired with the Powerex dew point monitor
may be operated in Econ Mode where the dew point monitor will
signal the dryer to cease purge if system dew point is below the set
point. The dryer control forces purge cycles at predened intervals to
assure proper operaon.
Frames or Tank Mount Structure
Powerex designed the system to bear the weight and stress of the
compressor pumps, controls, and receiver tank and dryers. When
liing the system, use the designated fork li slots or rig straps to
li the main system skid. Do not aempt to li the system using
individual component liing hooks and eyes. Piping may need to be
supported during li up or transport to avoid damaging the supplied
ex connectors for intake and exhaust.
Systems will require interconnecon of modules on site. Make sure
individual modules are located per the design drawing and pneumac
and electrical connecons are made as shown in the supplied wiring
diagram. Some systems will have separately mounted inlet manifolds.
Condensate Traps & Automac Drains
Powerex 7.5-10 HP scroll systems are equipped with cyclonic
condensate traps aer the aercoolers. Each trap has a “quiet zone”
near the boom of the bowl and the accumulated condensate is
piped to a common mer drain through a service isolaon valve.
The mer drain assembly is duplexed so the system remains fully
funconal if our mer drain valve is isolated for service. Under
normal condions the valves to one or both may be opened. Adjust
the mer sengs to increase duraon and frequency of opening if
large amounts of condensate accumulates in the receiver tank.
A similar mer drain is installed to drain the tank. Adjust the mer
to increase duraon and frequency if condensate accumulates in the
tank.
Operaon at High Altudes
Compressor pumps are sensive to reduced atmospheric pressure
encountered as altude increases. Powerex will adjust the operang
set points to compensate for altude if the original order is designated
for high altude and the expected condions provided to us.
Installaon
Disconnect, tag and lockout power before
aempng to install, service, relocate or perform
any maintenance.
Do not li or move unit without appropriately rated
equipment. Be sure the unit is securely aached to
liing device used. Do not li unit by holding onto tubes or coolers. Do not
use pumps to li other aached equipment.
Installaon of inlet / outlet air plumbing from
the system and electrical connecons must be
in accordance with Naonal Fire Protecon Associaon (NFPA99) Code
Compliance for Medical Gas Breathing Air (Level 1).
Installaon Site
1. The compressor system must be located in a clean, well lit and
well-venlated area.
2. The area should be free of excessive dust, toxic or ammable
gases and moisture.
3. Never install the system where the surrounding temperature is
higher than 104°F or where humidity is high.
4. Clearance must allow for safe, eecve inspecon and
maintenance.
5. If necessary, use metal shims or leveling pads to level the
system. Never use wood to shim the unit.
NOTE: Minimum of 36 in. of clearance is recommended on all sides.
36 in. is required in front of the electrical panel. 24 in. is required
on the remaining sides.
Venlaon
1. If the oil-less compressor system is located in a totally enclosed
room, an exhaust fan with access to outside air make up air
must be installed. Room temperature must remain below
104°F. Circulaon must be sucient to prevent local hot spots.
2. Never restrict the cooling fan exhaust air. Maintain a minimum
of 24 in. of clearance around the enre unit (36 in. is preferred).
3. Never locate the compressor where hot exhaust air from other
heat generang units may be pulled into the system.
Vibraon
The Powerex Scroll systems are designed to minimize generated
vibraons by using balanced rotary scroll pumps. Each pump is
mounted on base plate with a motor and the base mount assembly is
isolated from the main support frame by use of cork-rubber pads at
the support points.
Powerex scroll systems are provided with cork-rubber vibraon
isolaon pads for use between the base plaorms and the facility
oor to give further isolaon. Normal pracce is to install a pad
at each corner. Drill a hole through the pad to accommodate the
fastener selected to aach the base plaorm to the oor, posioning
the hole to maximize the contact between the plaorm lower surface
and the pad. When ghtening the fastener, apply sucient torque to

All electrical hook-ups must be performed by a qualied electrician.
Installaons must be in accordance with local and naonal electric
codes. Make sure power supply conductors are sized adequately for
full system demand.
Use solder-less terminals to connect the electrical power source.
Piping
General Guidelines
Refer to the general product manual.
1. Make sure the piping is lined up without being strained or
twisted when assembling the piping for the system.
2. Appropriate expansion loops or bends should be installed at
the system to avoid stresses caused by changes in hot and cold
condions.
3. Piping supports should be anchored separately from the
system to reduce noise and vibraon.
4. Never use any piping smaller than the system outlet connecon.
5. Use exible hose to connect the outlet of the system to the
piping so that the vibraon of the system does not transfer to
the piping.
Remote Intake Piping
Powerex Compressor Medical and Laboratory Air Systems with
7.5 and 10 HP pumps are constructed manifolds with a single point
connecon for remote air intake. Piping for remote intake system
must be installed at the nal operang site. Under some condions,
the intake piping may facilitate the condensaon of humidity in the
intake air stream into liquid water.
water going into the pumps will damage the pumps and void the warranty.
The intake lters supplied by Powerex will not
stop ingeson of liquid water by the pumps. Liquid
Always install drip legs with sucient capacity to capture liquid
water in the intake piping before the system connecon points. Drip
legs must be sized with low enough air velocity to make sure they
are eecve at capturing liquid water in the intake air and must be
maintained (drained) at frequent intervals to make sure they remain
eecve.
take up any slack, but do not crush the pad. Pads are most eecve
when they are lightly loaded.
In some cases alternate isolaon devices may be preferred. Install
them according to the recommendaons of the device manufacturer.
If desired, addional support points may be selected and holes drilled
in the base as needed to accommodate the design.
auto. Operaon with closed valves will damage the pump. The intake
isolaon valves have had the handles removed and a handle or handles
are provided inside the electrical panel. Powerex strongly recommends the
valves opening and closing be controlled to avoid pump damage.
Intake isolaon valves must never be closed
when the connected compressor is running or in
Safety Valves, Pressure Vessels, and Piping
1. Powerex systems are shipped with ASME safety valves sized so
that the maximum system ow is less than the capacity of the
valve or valves at the rated pressure. The rated pressure of the
valve is equal to or less than the maximum allowable working
pressure of the vessel or upstream pressure bearing parts. DO
NOT MODIFY or install any valves with dierent specicaons
unless appropriate evaluaons are completed. Do not modify
the structure of the pressure vessel or weld on the vessel.
2. Do not install any shut o valves between the safety valve
and the vessel or between the compressor pump and the
rst system safety valve. Doing so can result in a dangerous
condion and lead to death or injury.
3. Do not install shut o valves in the system that create trapped
compressed air.
4. Manually operate the safety valve every six months or 2,500
operang hours to provide assurance that the mechanism is
free to operate. Replace valve if it is leaking when it is closed
or if it fails to vent when actuated.
5. Any piping or pressure bearing connecon hose or tubing used
in the system must be rated equal to or higher than the safety
valve pressure rang. Inadequate pressure rang could result
in bursng.
Modular Placement
1. Unpack each frame module and discard or recycle all wood
shipping materials.
2. Systems consist of mulple frame modules. The steel base
plaorms are intended to be bolted to the oor as shown in
the design drawings and connecng hoses provided (found in
the parts pack box). Systems may be placed on isolaon pads
if desired. Modules may be spaced farther apart without any
structural problems, but electrical connecons may need to be
modied—addional isolaon pads and longer hoses may be
needed.
3. Place frame modules at locaon designated on build drawing.
Provide sucient clearance around system for servicing (see
minimum clearance secon).
Connecng Piping
1. Locate connecon for piping at rear of compressor module to
receiver tank module.
2. Remove plasc caps or adhesive covering on ports and
connectors.
3. Connect ex line to the ports making sure each ex line is not

Sensor Sample Flow
The dew point sensor must operate in compressed air at the
pressure equal to that at which the dew point is desired to be
measured. The sensing chamber must be provided with a small ow
of air from the system which is being measured. The sensing chamber
and ow control orice are designed to provide the pressure and ow
required. Do not close the ow orice. Doing so will result in a “dead
headed” condion for the sensor and the measured dew point will
not reect condions in the system pipe.
Sensor Calibraon and Adjustment
The sensor is fully calibrated as shipped from the factory (see
calibraon sheet included in the main system manual). With the
Daily Auto-Calibraon feature (listed below) the sensor may not need
replacement for up to 10 years. The manufacturer recommended
replacement interval is 2 years from system start-up or if sensor
should malfuncon.
Replacing the Filter
The sensor is protected with a stainless steel sintered lter. The
ltering grade is 34 um.
The lter is recommended to be changed whenever it looks dirty or
as a part of the periodical maintenance procedure. The recommended
replacement interval depends heavily on the applicaon and can vary
from less than a year to several years. Dirty or corroded lter may
cause increased response mes. In case the sensor is used in a drying
system with silica gel (or other drying agent) the dust from the dryer
may collect on the sensor slowing the response but also generang a
micro climate around the sensor altering the dew point at the sensor.
This is easily corrected by changing or cleaning the lter. Since the air
from the Powerex system is ltered at the dryer exit, lter problems
are unlikely.
Installaon
Touching the sensor may damage it. Special
aenon shall be paid to avoid touching the sensor
when removing and replacing lters.
Daily Auto-Calibraon
The Daily Auto-Calibraon feature of the sensor is an automac
procedure which greatly reduces the possible dri in the dry end of
the dew point measurement. It is performed at one hour intervals, and
when the power is switched on. During auto-calibraon the sensor
is warmed for a short period (< 1 min) and the sensor capacitance
values are evaluated at the elevated temperature. The possible dry
end dri is then corrected to correspond to the calibrated values.
During the auto-calibraon the transmier outputs the Td value prior
to the procedure. Auto-calibraon is carried out only if several criteria
for the measurement environment are fullled. This ensures the
reliability of the adjustments, and maintains the excellent long term
stability that the patented technology oers. These criteria include
e.g. a suciently stable enough moisture level in the measured
atmosphere. If the condions are not fullled, the auto-calibraon
funcon is postponed unl the sased condions are reached.
Sensor Purge
Sensor purge is also an automac procedure that minimizes the
dri at the wet end readings of the dew point measurement. Sensor
purge is performed once a day or when the power is switched on.
The sensor is heated for several minutes which will then evaporate all
excess molecules out of the sensor polymer. This, together with the
auto-calibraon results in a very small dri of the sensor due to the
very linear behavior of the polymer technology.
Sensor Warming in High Humidity
Addionally the sensor has a warming feature which prevents the
sensor and lter from becoming wet in high humidity. High humidity
can be present when the dew point temperature rises close to the gas
temperature. Sensor warming is switched on automacally when the
humidity level in the measured gas increases to a level where dew
can start to form. The advantage of sensor warming is rapid response
of dew point measurement. A wet sensor and lter would otherwise
result in a dew point equal to ambient temperature (i.e. RH=100%). If
the sensor becomes soaked in any way, it will fully recover and return
back to normal operaon aer it dries out.
