7.0 PRINCIPLES OF OPERATION

7.1 INTRODUCTION

Ingersoll Rand Nirvana™ Cycling dryers remove moisture

from compressed air by cooling the air temperature to
between 34° and 38°F (1 and 3°C). This causes vapors to
condense into liquid droplets which can then be easily
removed from the air. The major systems of the dryer which
contribute to its operation are the Air System, the Moisture
Removal System, the Refrigeration System, the Thermal
Mass Circulating System and the Controls. The following
paragraphs describe each of the systems in greater detail.

7.2 AIR SYSTEM

The air system consists of the dryer components which are
in contact with the compressed air. Referring to
Figure 1 and following the bold “AIR FLOW,” hot saturated

air from the compressor enters the precooler/reheater
where the air temperature is reduced prior to entering the
chiller by the cool air exiting the air/moisture separator.
This precooling allows for the use of a smaller refrigeration
system. The air then goes into the chiller section where
it is further cooled to the desired dew point by a thermal
mass uid. The temperature of the thermal mass uid is
maintained by the refrigeration circuit and controls. The
air continues to the separator where moisture is removed,
thereby, allowing the cool, dry air to return back to the
precooler/reheater to be heated by the incoming moist
hot air. The air exiting the “reheater” portion of the dryer
should be approximately 15°- 20°F lower than the inlet air
temperature based on standard conditions at full rated ow.

7.3 MOISTURE REMOVAL SYSTEM

Ingersoll Rand condensate drains discharge condensed

moisture and lubricants (condensate) from compressed air
equipment.

Liquid droplets are removed from the air stream in the
separator. As the air and liquid mixture passes through the
separator it spins, slows down and then changes direction.
This causes condensate to fall out of the air stream and
collect in the bottom of the separator. The collected
liquid is removed from the separator by a timed electric
drain(standard) which is controlled by the Controller OR an
optional No-Air Loss drain.

7.3.1 SOLENOID DRAIN (STANDARD)

The Drain Open time and Drain Closed time are accessed
by depressing the appropriate button and using the up and
down arrows to change the value. The Drain Open value is
seconds; the Drain Closed value is minutes.

To obtain the optimum time values for operation of

•

the electric drain valve, set the drain closed time to
ve minutes and the open time to ten seconds.

After running the unit under full rated ow for

•

approximately 30 minutes, verify that when the
electric drain opens, all of the accumulated liquid is
discharged and then followed by a small burst of air.

6 ingersollrandproducts.com

7.0 PRINCIPLES OF OPERATION

If a small amount of liquid and a large amount of

•

air is discharged, decrease the on-time setting or
increase the o-time setting. If there is all liquid and
no air has been discharged, increase the on-time
setting or decrease the o-time setting.

The on/o-time settings will vary accordingly to

•

seasonal conditions. During the summer when
more moisture is present in the air system, a shorter
ontime that increases the valve opening frequency is
required. A longer o-time may be used during the
winter months when moisture levels are lower.

7.3.2 NO AIR LOSS DRAIN (OPTIONAL)

The condensate drain operates as a zero-air-loss drain,
returning air that is displaced in the drain bowl back into
the compressed air system. Consistent discharging of
condensate from compressed air equipment is essential for
proper equipment operation and performance.

The condensate drain uses a unique sensing method to
determine the level of condensate in the drain bowl. A
transducer located in the drain bowl continuously sends
out a signal 50 times per second. Once the transducer
determines that the level of condensate has reached a
predetermined level within the drain bowl, a signal is sent
to the no-loss drain valve to open. This operation permits
removal of condensate of up to 80 gallons per hour.

tube (expansion valve on water-cooled dryers) meters
the refrigerant for introduction into the evaporator.
The refrigerant pressure is reduced upon entering the
evaporator where as it evaporates, removes heat from the
thermal mass uid.

7.5 THERMAL MASS CIRCULATING SYSTEM

The thermal mass uid in a Ingersoll Rand Nirvana™
Cycling dryer is continuously circulated in a closed pump
loop system. Referring to Figure 1 and following the dashed
“THERMAL FLUID” line, the heat is removed from the uid
in the evaporator by the refrigeration system. The thermal
mass reservoir is sized to minimize refrigeration cycles
during reduced air load periods. The thermal mass uid
is pulled from the bottom of the reservoir and pumped
through the chiller, removing heat from the air and then
returned to the evaporator. The pump utilized on the
Ingersoll Rand Nirvana™ Cycling dryer is a maintenance­free, quiet cartridge circulator pump similar to those
used in residential water systems. While the refrigeration
system cycles on and o based on loading conditions,
the circulating pump runs continuously to maintain ow
through the chiller at all times. Note that when the power
switch is set to the o position, the circulating pump will
not operate.

7.6 CONTROLS

The drain also features a test button that permits manual
operation of the no-loss drain valve. Depressing the test
button illuminates the LED and energizes the solenoid
valve. The LED illuminates to indicate “POWER ON” and
goes o when the no-loss drain valve is operated by the
transducer or manual test button.

The condensate ows through the feed line into the drain
unit and accumulates in the container. A capacitive sensor
continuously registers the liquid level and passes a signal
to the electronic control as soon as the container is lled.
The pilot valve is then activated and the diaphragm opens
the outlet line for discharging the condensate. When the
drain unit has been emptied, the outlet line is closed again
quickly and tightly without wasting compressed air.”

7.4 REFRIGERATION SYSTEM

The Refrigeration System consists of all the components
which handle R-404A. This is a hermetically sealed closed­loop system. Referring to Figure 1 and following the
phantom “REFRIG(R-404A) FLOW,” refrigerant is shown
leaving the evaporator section where, in the process of
removing heat, it is changed from a low pressure liquid into
a low pressure gas. This gas enters the suction side of the
compressor where it is compressed into a high pressure gas.
The high pressure gas is cooled in the condenser section
until it becomes a high pressure liquid. It then goes through
a permanent lter dryer that ensures the refrigeration
system is free of contaminants. A small diameter capillary

The Ingersoll Rand NVC200-400 Series dryers incorporate
automatic controls for proper operation. The thermal mass
uid temperature is maintained by a microprocessor control
that monitors the temperature and cycles the refrigeration
system in response to varying air ow and temperature.
Upon an increase in the temperature of the thermal mass
uid, the refrigeration compressor is cycled on. When the
uid is cooled to two deg.F below its control set point, the
refrigerant compressor is cycled o. The thermal mass uid
functions as a thermal storage mass in the NVC Series dryer.

A low pressure cut out (LPCO) switch is provided for all NVC
series dryers. This switch is factory set to open at 20 psig. If
the refrigerant suction pressure draws below 20 psig, the
LPCO opens to shut o the refrigerant compressor. Once
the switch has opened, it will prevent the compressor from
running until the suction pressure rises above 60 psig and
the LPCO has been manually reset.

All water cooled units come with a high pressure cut out
(HPCO) switch. This switch is set to open at 320 psig and
close at 270 psig. To compensate for water temperature
variation, it may be necessary to adjust the water
regulating valve to maintain a 250 psig discharge pressure.
Adjustment can be done by rotating the adjusting screw
counterclockwise for an increase in discharge pressure.
For conditions where low water temperature and/or high
water pressure are expected it is advisable to install a water
pressure regulator ahead of the condenser.

7.6.4 ALARMS AND THEIR FUNCTIONS

condition may not necessarily damage the dryer when
subjected to long-term exposure. It may, however, have
a signicant impact on downstream processes and thus
should be investigated upon detection. Note that this alarm
will not shut down the dryer. This alarm will activate the
remote alarm contact and reset automatically once the
alarm condition is rectied.

LOW TEMPERATURE SAFETY ALARM

If the dryer chiller temperature falls below the factory set
point, the alarm routine will activate. This alarm condition
may cause damage to the dryer when subjected to
continuous or long-term exposure. Note that this alarm
will shut down the dryer after a response time delay. This
alarm will activate the remote alarm contact and reset
automatically once the alarm condition is rectied.

7.6.5 ALERT MESSAGES

The Controller features the following readouts to
communicate the status of the dryer’s operation.

Indicates a probe failure. This condition
is usually caused by a probe being
unplugged, damage to the probe lead or
a defective probe.

Indicates that the refrigerant compressor
will not start until the end of a three
minute safety delay. The display of “cd” is
immediately followed by the number of
minutes left in the delay. This is a normal
function of the controller and not a fault
indication.

7.6.6 START MODES

7.6.6.1 Manual Mode

After power is supplied to the dryer, the LCD display
will indicate the chiller temperature as well as the time
remaining for the safety delay. Once the delay has
timed out, depressing the On/O button will permit
the refrigeration system to operate. Should the chiller
temperature be greater than the set point, the refrigeration
system will energize. Should the chiller temperature be
below the set point, the refrigeration system will remain o
until the chiller temperature rises to the setpoint.

7.6.6.2 Remote Mode (Optional)

This mode of operation allows the user to control the
dryer remotely and requires the installation of a customer­supplied contact. With power applied to the dryer and once
the safety delay has timed out, the dryer will start once the
remote switch is closed. In addition, this mode of operation

ingersollrandproducts.com 9

7.0 PRINCIPLES OF OPERATION

still permits manual control of the dryer via the On/O
pushbutton on the local control panel. Note that if the dryer
was turned “On” from the remote switch and then turned
“O” via the local control panel, the remote switch must be
turned “O” and then “On” to reinstate the dryer.

8.0 INSTALLATION AND INITIAL STARTUP

8.1 LOCATION AND MOUNTING

The dryer should not be located in an area where ambient
temperature is likely to exceed 113°F (45°C) or be less
than 50°F (10°C). The dryer must be located in an area
that provides sucient clearance from walls and other
adjoining equipment to allow easy access for servicing
and maintenance requirements. A minimum of 18 inches is
required to allow free ow of air to the condenser inlet.

On installations with a relatively steady ow rate, the
dryer is normally connected after the air receiver. If loads
uctuate widely, the dryer should be positioned ahead of
the receiver and sucient storage capacity downstream is
necessary to prevent excessive air ow through the dryer.

7.6.6.3 Auto Restart

Should the dryer lose power while in the “On” mode, the
dryer will revert to the “On” mode once power is restored.
Similarly, should power be removed from the dryer while
the dryer is in the “O” mode, the dryer will remain in the
“O” mode once power is restored until the On/O switch is
depressed or the remote switch is closed.

8.2 PIPING AND VALVES

Install piping, ttings and accessories as required for
specic site conditions and requirements. Figure 3 indicates
a typical piping arrangement for a refrigerated dryer,
including dryer and lter bypasses. This gure can be used
as a guide for valve and accessory placement in the system.

Ingersoll Rand NVC200-400 models come factory installed
with a drain isolation valve (D). The isolation valve permits
maintenance of the automatic drain without isolating
air ow to the dryer. To operate dryer, all valves shown in
Figure 3 are to be closed except valves (B), (C) and (D). Valve
(A) is used for bypass purposes and valve (E) is for test and
manual drain purposes.

When installed after any compressor that causes
signicant vibration or air pulsation, such as reciprocating
compressors, proper vibration isolation and pulsation
dampening devices should be added to protect the dryer.

NOTICE

Failure to comply to the above instructions may
result in equipment malfunction and will void
warranty.

NOTICE

Always use a backup wrench when making any
threaded connection to the dryer. Failure to use a
backup wrench may result in damaged tubing and
components internal to the cabinet.

8.3 FILTRATION

To protect the air dryer from gross contamination
associated with compressor oil and debris and ensure
maximum dryer performance, a pre-lter is recommended.
Pre-lters and post-lters sized to your drying application
can be provided by Ingersoll Rand and are available
factory installed. Call your local distributor to select the
lter that best suits your ltration requirements. In addition
to air ltration, condensate discharge oil/water separators
are also available to address stringent EPA regulations.

8.4 ELECTRICAL CONNECTION

Equipment is available in various electrical congurations.
All customer connections can be made at the terminal
connections located in the customer electrical connection
box on the rear of the dryer. (Refer to General Arrangement
and appropriate Wiring Diagrams.)

A suitable fused disconnect switch or circuit breaker, in
accordance with national and local code requirements, is
recommended for all Ingersoll Rand equipment. Refer to
Section 13 for voltage requirements and load.

CAUTION

Never wire directly or connect any additional wires
to the compressor junction box. This will cause
severe system malfunction.

8.5 INITIAL START-UP

NOTICE

For water cooled models, the water valve must be
manually opened to ensure that the condenser is
full of water prior to start-up.

9.1 INTRODUCTION

Ingersoll Rand Nirvana™ Cycling refrigerated air dryers

require little maintenance. These dryers utilize hermetically
sealed compressors which do not require any lubrication.
Fan motors require lubrication at both oil ports every
six months. Ingersoll Rand recommends component
inspection and service at regular intervals to obtain
maximum performance from your dryer.

9.2 REFRIGERANT CONDENSER

For standard dryers, regular inspection and cleaning of the
condenser is recommended. Ingersoll Rand dryers may
be equipped with an optional ambient air lter designed
to protect the condenser from dirt and debris that can
accumulate on the condenser. For proper operation with
this option, it is imperative that this lter be inspected and
cleaned on a regular basis. Annual replacement of the lter
is recommended. For applications where excessive dirt, dust
or debris is encountered, more frequent inspection and
cleaning may be required.

been cleaned and inspected. Reposition the orice
hole on the rubber gasket of the orice cup in the
line and closest to the arrow indicated on the valve
body.

Reassemble valve and install in reverse order as

•

described above.

On a minimum of a monthly basis, the operation of the
drain should be checked. Periodically, the drain should be
removed and cleaned to ensure no debris from the system
is trapped inside. Ingersoll Rand dryers are equipped with

FIGURE4 SOLENOID DRAIN ASSEMBLY

a drain isolation valve, enabling the valves to be cleaned
during dryer operation after the drain isolation valve has
been manually closed. The drain valve is located near the
solenoid valve and requires a quarter turn to isolate the
drain from system pressure.

9.3.1.1 Cleaning Instructions - Solenoid Drain

Be sure dryer is depressurized or isolation valve is

•

closed.

Disconnect drain body from lter stop.

•

Loosen connector screw to allow the electrical

•

connector assembly to be removed from the D.I.N.
unit solenoid.

Remove retainer nut and separate the valve body

•

from the D.I.N. unit solenoid. Unthread the plunger
tube assembly in a counterclockwise direction until
plunger separates from valve body.

Clean beveled washer, thread gasket, spring

•

assembly and strainer with soap and water. Do NOT
use solvents of any kind, as failure to the seals will
occur.
Be especially careful to clean the center brass orice
and the rubber gasket orice on the orice cup with
a straight pin.

Reassemble all drain components after the drain has
