Example: To size for an inlet flow of 950 SCFM @ 105 F and 110 psig.

1.Select model that produce at least 950 SCFM at 110 psig. This case would be the TZE1000 which can dry 1140 SCFM.

2.Multiply pressure corrected flow by the temperature correction factor to obtain the flow of the dryer corrected for pressure and temperature:

1140 X (0.85) = 969 SCFM

3.Confirm model selection. Model TZE1000 can flow 969 SCFM at the inlet conditions specified; requirements of 950 SCFM are less: TZE1000 is correct.

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.

1.6TRANSPORT

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.

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.

2.2MECHANICAL 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.

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

TO 100 FEET

3 SIZES LARGER THAN DRYER EXHAUST

Caution!

The noise at the outlet of the exhaust header may exceed 100 dBa, and the flow velocity will be high. Exhaust must be piped to an area where these flow velocities and noise levels can be safely tolerated.

2.3 FILTER INSTALLATION

2.3.1 PREFILTER INSTALLATION (SHIPPED LOOSE)

Mount prefilter in such a way as to allow clearance for the element installation and removal.

Locate the prefilter as close to the dryer inlet connection as possible.

The filter must be piped so that the correct flow direction indicated on the filter is followed.
