2. INSPECTION AND INSTALLATION
2.1 Incoming Inspection and Transportation
All dryers are tested and inspected at the factory prior to shipping. Thoroughly inspect and verify the integrity of the
packaging upon receipt and note any damage on the freight bill. Place the unit as close as possible to the installation
point before unpacking the contents and inspect for concealed damage. Freight claims are to be filed with the carrier
immediately and the manufacturer’s technical service department notified thereafter.
To move the packaged unit, we suggest the use of a suitable crane or forklift. We do not recommend moving the
unit by any hand operated or manual mechanism.
Handle with care. Heavy blows could cause irreparable damage.
Even when packaged, keep the machine protected from severe weather.
The packaging materials are recyclable. Each material must be properly disposed in a manner complying
with the rules and regulations of the local municipality government.
2.2 Design and Use of the Dryer
This dryer has been designed, manufactured and tested to be used only to separate the humidity normally contained in
compressed air, any other use is considered to be improper. The manufacturer is not responsible for any problems
arising from the improper use of this machine.
The end user, in any and all cases, is responsible for any resulting damages.
Moreover, the correct use of this machine requires the verification of certain installation conditions, in particular:
Voltage and frequency of the electrical power supplied
Pressure, temperature, flow rate and chemical composition of the incoming compressed air
Ambient temperatures
The dryer is supplied as tested and fully assembled. The only operation left for the end user is the connection to the plant
and adjustment of the purge rate in compliance with the instructions given in this manual. Factory settings are at
nominal conditions at 100 psig and the stated model flow rate (see page 5).
The purpose of the machine is the separation of water vapor that is present in compressed air. It is not
intended to separate oil or other contaminants that are present in compressed air.
The dried compressed air output from this dryer cannot be used for respiration purposes of any kind.
2.3 Location and Installation
Serious consideration should be given when selecting the installation site for the dryer, as an improper
location could directly affect the proper operation of the dryer.
This unit is not suitable to be used in explosive atmospheres, where risk of fire could exist, in the presence
of gaseous or solid pollutants or in outdoor applications or areas exposed to the elements.
Do not use water to extinguish fire on the dryer or in the surrounding area.
Machine level noise could be higher than 85 dBA. Install the unit in a dedicated area where people are not
normally present. The installer and/or end user is responsible for the correct installation of the dryer in
order to prevent excessive noise exposure in the work environment. The installer and/or end user is
responsible to install proper safety signs at the installation site.

iDRY Series Heatless Regenerated Dryers: IOM10003-C (Rev. A) 5
Technicians that service the machine must wear hearing and eye protection while servicing the dryer. Each
employee must select a proper personal protection device (PPD) hearing protector such as earmuffs, ear
canal caps or earplugs in order to prevent permanent hearing damage or loss.
Minimum Installation Requirements:
Select a clean, dry room that is free of dust and protected from atmospheric disturbances.
The location must be smooth, horizontally level, able to bear the weight of the dryer and vibration free
Minimum ambient temperature of +40 °F
Maximum ambient temperature of +120 °F
Allow a clearance of at least 3’ on all sides of the dryer in order easily facilitate all maintenance needs
The dryer is not required to be anchored to the supporting surface
Coalescing pre-filter with drain must be installed
The location of an air receiver tank will vary depending on compressor type and application conditions
Incorrect installation may void warranty.
NOTE: All piping and electrical connections should be inspected prior to installation to ensure they have maintained
their integrity during shipping and locating the dryer.
First, make the initial connections as follows:
1. Inlet piping including an isolation valve
2. Outlet piping including an isolation valve
3. Coalescing pre-filter and particulate post-filter
We recommend the dryer be installed with a 0.01 micron iPUR coalescing pre-filter at the inlet and a 1.0 micron
iPUR particulate post-filter at the outlet. It is recommended to install both 5.0 micron and
1.0 micron filters upstream of the dryer in order to maintain the operational lifespan of the inlet filter to the
dryer. In addition, we recommend the use of a iMAT zero air loss drain on the pre-filter and at all other
condensate collection points, especially those upstream of the dryer.
Locate the coalescing pre-filter as close to the dryer as possible while still maintaining sufficient space for routine
maintenance and service. Inlet air entering the dryer must pass through a coalescing pre-filter in order remove entrained
condensate and oil to prevent fouling of the desiccant and maintain standard operation. Any liquid condensate entering
the desiccant bed will lead to overloading of the dryer, poor dew point performance and rapid deterioration of the
desiccant material. Any oil entering the desiccant bed may permanently reduce the capacity of the desiccant material.
Desiccant dust traveling downstream of the dryer may cause contamination and/or accelerated wear to other
components and equipment. Therefore, a particulate post-filter should be provided to prevent desiccant dust from
traveling downstream. Activated alumina is considered a nuisance dust and proper precautions should be taken when
handling desiccant (refer to applicable MSDS sheet).
4. IMPORTANT! Bypass piping is necessary. Only bubble tight valves should be used.
5. Make the required electrical connections; please refer the type plate of your dryer. The end user is
responsible for providing short circuit protection for the dryer.
6. Points of access should be provided upstream and downstream of the dryer for periodic monitoring of
dew point, pressure and temperature prior to finalizing the installation. Taking periodic dew point
measurements just downstream of the dryer gives the best indication of whether the dryer is
performing optimally. We recommend using METPOINT® instrumentation to ensure accurate
measurements.
7. All piping must be adequately supported and at least of equal size to the dryer connections.

Optimal installation is with moderately sized receivers at the inlet and outlet side of the dryer. This allows for the
additional free cooling and moisture collection and more consistent dryer inlet flow provided by an upstream receiver,
while providing the most reliable shop air supply due to the downstream receiver.
Under no circumstances should the peak demand air flow exceed the maximum rated air flow of the dryer.
We recommend the dryer be installed with a 0.01 micron iPUR coalescing pre-filter at the inlet and a 1
micron iPUR particulate post-filter at the outlet. It is recommended to install both 5 micron and 1 micron
filters upstream of the dryer in order to maintain the operational lifespan of the inlet filter.
2.4 Mounted Filters with Bypass
Mounted Filters with Bypass is an optional setup for the heatless regenerative
dryer. The three valve system bypass allows for the flow of air to be uniterupted
while servicing or completing preventative maintinance such as:
Exchange pre- and post- filters
Services exhaust sIlencers
Change desiccant

3.3 General Function
The iDRY iDHLBe heatless desiccant dyer series are fitted with two pressure vessels, positioned parallel to one another
and filled with adsorption material (⅛” activated alumina as standard). While the compressed air is dried in one tower,
the saturated desiccant is regenerated in the second. A minimal portion of the treated air is used for the regeneration
process and expelled along with the condensate, through the silencers.
The saturated inlet air is cycled through each of the two desiccant beds in an alternating sequence where one bed is on-
line at full line pressure and flow, adsorbing the water vapor. This is the drying bed.
The other bed is then considered to be in an off-line state at atmospheric pressure and is being regenerated by a
depressurized portion of the dried, treated outlet air (purge air). This is the regenerating bed.
The purge air is routed from the dry outlet air through the purge flow control valve, desiccant bed, purge exhaust valve
and finally exhausted to atmosphere through silencers to finish the regeneration process. Purge air consumption is
generally the highest cost involved with operating a heatless adsorption dryer and is non-recoverable. Therefore, the air
system where the dryer is installed must account for this usage (approximately 15% of the inlet air flow).
Just before the freshly regenerated bed is brought to an on-line state to become the drying bed, it is slowly pressurized
from atmospheric pressure up to line pressure. This is the re-pressurization step that prevents desiccant bed fluidization
(bed lifting) and dusting. The desiccant beds will now switch functions where the fresh desiccant bed is now drying and
the saturated bed is now regenerating.
This cycle will continue automatically unless the dryer is shut down.
All desiccant dryers work using the principle of adsorption, which is the process by which water vapor is removed from
the compressed air being dried. All desiccant material types are adversely affected by oil, aerosols, dirt, rust, scale and
