1.5 OVERLOADING
Attention! Protect the adsorption dryer from overloads!
The adsorption dryer can become overloaded if:
• The flow volume of the medium to be dried increases
• The temperature of the air at entry and, correspondingly, its
humidity increases
• The minimum operating pressure decreases
• The prefiltration and separation of impurities are not sufficient or the
filter drain fails
• Introduction of oil into the air stream.
1.6 TRANSPORT
Immediately upon delivery of the adsorption dryer, it must be checked for any damage
that may have occurred during transport. If necessary, the damage must be recorded
on the shipping waybill/receipt. Liability for such damage usually rests with the shipper.
Contact Ingersoll-Rand to arrange for any required service or replacement parts.
Attention!
For transport within your company site, only the skids of the adsorption
dryer may be used. Lifting at any other points on the equipment will void
the warranty and damage the equipment.
1.7 STORAGE
If the adsorption dryer is to be stored for a long period of time, its place of storage must
be dry and free of dust. The ambient temperature cannot go below 33°F (+1°C).
1.8 USE OF A PREFILTER AND AFTERFILTER
In order to prevent droplets of condensate, oil and dirt from getting into the desiccant, a
Ingersoll-Rand prefilter must be installed upstream of the adsorption dryer. An oil film
on the desiccant reduces the drying capacity and the dewpoint. In order to prevent
breakdown in downstream consumers caused by material that has been abraded from
the desiccant bed, a Ingersoll-Rand afterfilter must be mounted behind the adsorption
dryer. Since no condensate accumulates in the afterfilter, this filter is always equipped
with a manual vent valve.
8
USER MANUAL
TZE400 to TZE3500 with EMS
REV 10 – 23 February 2006
Both filters are equipped with a differential pressure indicator to ensure a direct display
of the degree of contamination of the filter elements.
2. INSTALLATION
2.1 GENERAL
Ensure that the installation site is free of dust, dirt and litter. The site floor must be level
and strong enough to support the equipment. The site itself must be an heated
environment (minimum 50°F) to ensure proper operation and warranty protection.
Ensure that the Ingersoll-Rand adsorption dryer is carried only by its skid base frame.
The adsorption dryer must be positioned so that the side from which it is to be operated
is easily accessible. The piping is to be connected at a slightly downward slope. Install
isolation valves on the inlet and outlet sides of the adsorption dryer. Also, a bypass
pipe with an additional isolation valve should be mounted onto the adsorption dryer to
allow for an uninterrupted supply of compressed air in case the adsorption dryer
requires maintenance or repair. The bypass assembly is optionally provided (see
paragraph 1.2) or can be customer furnished. If vibrations occur at the installation site,
the adsorption dryer skid frame is to be placed onto vibration dampers.
2.2 MECHANICAL ASSEMBLY
• The equipment should be located in an area with adequate clearances for
service. An overhead clearance of not less than two feet above each desiccant
tower is required for loading of the desiccant.
• Remove all protective shipping crates, flange covers, etc.
• Using the mounting holes provided on the skid, anchor the dryer to a solid, level
foundation designed to support the equipment.
• Do not hydrostatically test the pressure vessels. All TZE dryer pressure vessels
and welded piping are hydrostatically tested at one and one-half times the design
pressure after fabrication and before assembly.
• Desiccant for models TZE820 and up is shipped loose and must be installed on
site. Refer now to paragraph 4.3 for instructions on installing the desiccant.
• If the equipment is installed in a high traffic area, protective barriers may be
required to prevent possible damage of equipment and to prevent contact with
hot surfaces.
• Due to vibration during shipping some tube fittings may have loosened.
Therefore, inspect all connections and tighten if required.
9
USER MANUAL
TZE400 to TZE3500 with EMS
REV 10 – 23 February 2006
• Ensure that the inlet and outlet connections to and from the dryer are made using
the correctly rated fittings and piping to meet the design conditions.
NOTE: System isolation and by-pass valves should be installed. If not supplied
by Ingersoll-Rand as part of the equipment package (i.e., 3V option – see
paragraph 1.2), they should be supplied and installed by others. Ensure
that this bypass facility is installed so that future servicing of the dryer
system off-line may take place.
• Full flow relief valves to protect the system from over-pressure must be
customer-provided in accordance with local regulations.
• The purge exhaust on the TZE650 and smaller dryers is equipped with an
exhaust muffler. If required, the muffler can be removed and purge exhaust can
be connected to a vent header. Follow recommendations for pipe sizing listed
below.
• The purge exhaust connection on the TZE820 and larger dryers must be
connected to a vent header. To ensure satisfactory regeneration of the desiccant
chambers, the purge exhaust piping should be sized as follows to prevent backpressure build up.
EXTENDED LENGTH PIPE SIZE REQUIRED
TO 10 FEET SAME SIZE AS DRYER EXHAUST
TO 25 FEET 1 SIZE LARGER THAN DRYER EXHAUST
TO 50 FEET 2 SIZES LARGER THAN DRYER EXHAUST
