Advice for protection: If desiccant comes into contact with the eyes, rinse eyes immediately with large

amounts of clear water. If the desiccant is spilled, clean up with effort to minimize the formation of dust. In case of fire, there is no restriction on the use of fire extinguishing material. A small dust mask must be worn.

1.3 PERSONNEL QUALIFICATION The personnel involved in operation, maintenance, inspection, and assembly must have the corresponding qualifications to do this work. Areas of responsibility and supervision of the personnel must be precisely established by the operator. Should the personnel not possess the necessary knowledge, then they must be trained and instructed. If need be, this training may be carried out by the manufacturer / supplier at the request of the operator of the adsorption dryer. Further, the operator is to make sure that the personnel completely understand the contents of the technical manual.



SECTION 1: (Continued) 1.4 PRODUCT INFORMATION

The adsorption dryer is used for the purpose of drying compressed air and other gases according to its respective design. As a "standard model" the adsorption dryer is equipped with two desiccant vessels and, depending on certain conditions, provides pure, dry and oil-free compressed air or gases.

1.4.1 Theory of Operation The HC heat-of-compression dryer uses the hot air from the compressor to regenerate the desiccant. Each tower is sized for a minimum of 4 hours online, but may be extended by use of the optional DPDS which will allow the dryer to switch towers based on water load rather than time. The DPDS (Dewpoint Demand System) is optional equipment and may or may not be present on your particular air dryer. If your dryer is equipped with the DPDS, see the associated DPDS Installation and Operating Guide for more operational details. The regeneration cycle is split up into three functions.



SECTION 1: (Continued)

A. Regeneration Cycles

1. Heating. Hot air directly from the compressor enters the inlet of the HC and is directed by the inlet 2-way valves into the regenerating tower. This hot, thirsty air regenerates the bulk of the water from the desiccant. The air is then directed into the aftercooler where it is cooled, the coalescing separator where liquid water is removed through the drain trap system, then into the drying tower where the air is actually dried to its final low dewpoint. The heating cycle lasts 90 minutes.




2. Stripping. At the end of heating, the inlet valves shift position, directing the hot inlet air directly into the aftercooler, separator, and drying tower. We now begin stripping. The stripping phase of regeneration lasts 90 minutes. At the beginning of stripping, the regenerating tower is depressurized through a muffler. During stripping, a small adjustable flow of dry air is used to remove the last little bit of moisture from the regenerating tower.




3. Cooling. At the end of stripping, the regenerating tower is repressurized. The cooling cycle valves open and cooling begins. The cooling cycle lasts 60 minutes. During cooling, a portion of the dry outlet air is directed into the regenerating tower to reduce the temperature of the bed prior to tower shift.




1.4.2 Pressure vessel regulations

The pressure vessels are designed according to the standard technical requirements. They fulfill the test of the certifying procedure and carry the U, UM ASME Symbol.

Range of Application:

Type HC-3 HC-239

Operating overpressure Max. 150 PSIG

Operating Temperature Max.Min.

500F 20F

Attention! Never weld on or alter a pressure vessel in any way!

1.4.3 Airtightness test

All adsorption dryers are subjected to an airtightness test prior to shipment using compressed air.

1.4.4 Overloading

Attention! Protect the adsorption dryer from overloads! The adsorption dryer can become overloaded, if: The inlet flow is too high, The temperature of the air at the discharge of the

aftercooler is too high, The min. operating pressure is too low, The temperature of the air at the discharge of the

compressor is too low.

SECTION 1: (Continued) 1.4.7 Transport

After the adsorption dryer has been delivered, it must be checked for damage that may have occurred during transport. The Transport Company must be informed to register any damage. Shipping damage is not covered by any warranty.

1.4.8 Storage If the adsorption dryer is to be stored for a prolonged period of time, it should be stored in a dry place, preferably indoors; protected from the elements including freezing or extremely warm temperatures.

1.4.9 Use of a pre and afterfilter Use of a prefilter is not necessary with a heat-of-compression dryer. An afterfilter should be provided to prevent desiccant dust from migrating downstream.



SECTION 2:

INSTALLATION 2.1 SET-UP AND INSTALLATION

Once at the installation location, the adsorption dryers of the series HC-3 HC-239, which are supplied with a base frame, must be positioned so that all sides are easily accessible. Should vibrations occur on the installation location, the adsorption dryer is to be placed onto vibration dampeners. Since the adsorption dryer has already been completely wired at our factory, the customer only has to connect the power supply cable to the terminal strip according to the supplied wiring diagrams.

Advice Should you still have questions regarding installation, you can request installation blueprints separately from IInnggeerrssoollll--RRaanndd Davidson NC.

Warning! Use the appropriate, load-rated lifting equipment and observe safe lifting procedures during all operations of installation. The equipment should be unloaded as close as possible to the installation site to minimize any chances of equipment damage.



SECTION 2: (Continued) 2.1.1 Mechanical installation

The equipment should be located in an area as practically possible with

adequate clearances for service. An overhead clearance of not less than three feet above each adsorber tower is required for loading of the desiccant. Access clearance of three feet in front of the control panel should be provided. Insulate the pipe between the compressor and dryer to minimize heat loss. Remove all protective shipping crates, flange covers, etc.

Utilizing the mounting holes provided on the skid, anchor the IInnggeerrssoollll--RRaanndd type HC Dryer to a solid, level foundation designed to support the dryer.

Do not hydrostatically test the pressure vessels. All HC dryers pressure vessels are hydrostatically tested at one and one-half times the design pressure after fabrication and before assembly.

Desiccant is shipped loose (HC-41 and above) and must be installed. Refer to section 4.2 for installation of 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.

Because of vibration during shipping, some tube fittings may have loosened; therefore, inspect all connections and tighten if required. Also, flange connections may have loosened; therefore tighten all flange bolts.

Ensure that the inlet and outlet connections to and from the IInnggeerrssoollll--RRaanndd type HC Dryer are made using the correct rated fittings and piping to meet the design conditions.

System isolation and by-pass valves should be installed. If not supplied as part of the equipment package by IInnggeerrssoollll--RRaanndd, they should be supplied and installed by others. It must be verified that these exist, so that future servicing of the Dryer System may take place.

Full flow relief valves to protect the system from over-pressure must be provided by others in accordance with local regulations.

The purge exhaust connection on the HC larger dryers may be connected to a vent header. To ensure satisfactory regeneration of the desiccant chambers is achieved, the purge exhaust piping should be sized as follows to prevent "back pressure" build up.

Installed length of exhaust pipe Pipe size required

Up to 10 Ft Same size as the dryer exhaust Up to 25 Ft One size larger than dryer exhaust Up to 50 Ft Two sizes larger than dryer exhaust Up to 100 Ft Three sizes larger than dryer exhaust



SECTION 2: (Continued) 2.1.2 Filter installation

Series HC dryers are shipped with the afterfilter loose or with the filter skid mounted on a separate steel frame. The following installation applies to all models that are shipped with filters loose. Afterfilter Installation Mount afterfilter in such a way as to allow clearance for the element

installation and removal. The filter must be piped so that the correct flow direction indicated on the

filter is followed. Ensure that all piping and valves are equivalent or larger in size to the dryer

inlet connection. Filter Skid with 3-Valve Bypass Installation Filters skid should be located as close to dryer as possible. Use the skid bolt

holes to secure the assembly. Ensure that the skid is located such that the 3-valve bypass will bypass the

dryer and filters when in use. Check the flow direction of each filter to ensure the after filter is connected to

the outlet pipe of the dryer. Connect the filter skid piping and dryer skid piping using materials and

fabrication procedures that are suitable for compressed air pressure piping. All flanges are ANSI B16.5 Class 150 Raised Face flanges.



SECTION 2: (Continued) 2.1.3 Electrical installation

Connect the dryer to a correctly sized power supply. The dryer requires a 115V 60 cycle connection. A disconnect switch is not provided with the dryer and must be supplied by end user in accordance with the recognized electrical codes.

Ground the frame of the dryer in accordance with the recognized electrical codes.

It is recommended that the common alarm relay, located in the dryer control panel, be connected to the control room or operator station so that an immediate response to the dryer alarm may be given when required.



SECTION 3:

START UP AND OPERATION 3.1 START UP

Attention! All pipes and wire connections are to be tightened! Furthermore, before start-up: The pipes must be checked for the presence of scale,

abraded material from the threading, or other similar impurities.

All shut off valves on the adsorption dryer, after-filter and on the bypass line should be closed.

The ambient temperature must not be less than 33F.Breakdowns resulting from faulty installation do not fall under IInnggeerrssoollll--RRaanndd's warranty obligation.

3.1.1 Pressurizing dryer

Prior to pressurizing the IInnggeerrssoollll--RRaanndd Series HC Dryer system, verify the following:

- Dryer On Off switch is in the off position. - System outlet block valve is closed. - Cooling water is turned on to the aftercooler.

Slightly open the inlet isolation valve slowly admitting compressed air to the

system. When full system operating pressure has been reached all connections should be soap bubble tested for leaks. Any leaks should be repaired and retested prior to placing the equipment in service. If some gas other than the process air will be used for leak testing, consult IInnggeerrssoollll--RRaanndd for its compatibility with system components before proceeding. Fully open the inlet isolation valve.

When the system is filled with process air, is leak tight and start-up is

completed, then slowly open the system outlet valve to pressurize the downstream piping. During the procedure, ensure that the dryer system pressure does not fall below 95% of its reading prior to opening the system outlet valve. This will protect the equipment internal components (i.e. filter elements, desiccant) from gas velocities above design conditions.



SECTION 3: (Continued) 3.1.1 Pressurizing dryer (Continued)

When pressurizing is complete then fully open the system outlet valve to place the equipment in service.

Verify the system inlet pressure and temperature are at the design operating

levels. 3.1.2 Energizing dryer controls

Turn ON-OFF switch to the ON position. A Micrologix programmable controller with individual input/output modules

controls the dryer cycle. A copy of the program complete with a full listing of inputs, outputs, internal coils, timers and counters is included later in this manual. This should be used as a reference guide to ensure dryer is cycling. A manual mode is included in the dryer program to allow for fast cycling to verify the operation of the dryer.

While dryer is in the stripping mode for either chamber, the regeneration flow

setting should be checked. The stripping flow valve should be set at 1.5 turns open at start-up and adjusted as necessary to maintain the specified dewpoint. The pressure gauge on the regenerating tower should not exceed 10 psig.

Warning! Failure to correctly set the stripping flow can lead to improper regeneration of the desiccant bed, resulting in a dewpoint failure when that chamber is returned to service.

It is recommended that the operational program of the dryer and the wiring schematic be studied before operating the dryer.

NOTE : If the DPDS (Dewpoint Demand System) option is purchased,

reference the DPDS Installation and Operating Guide for instructions.

SECTION 4: MAINTENANCE

Advice: In order to ensure continuous and trouble-free operation, a maintenance contract with IInnggeerrssoollll--RRaanndd is recommended.

4.1 SUGGESTED PREVENTIVE MAINTENANCE SCHEDULE

4.1.1 Introduction

The Series HC compressed air dryer requires a minimum of maintenance as most components are "maintenance-free". However, a certain amount of "preventive maintenance" is recommended to assure years of trouble-free, high-performance service.

4.1.2 Periodic Maintenance Schedule

Whereas it is recommended that the dryer be observed and inspected as often as it is practical, the following is a minimum requirement:

A. EVERY 2000 HOURS OR 3 MONTHS

1. Check the inlet air temperature; make adjustments, if necessary. 2. Check the air temperature at intercooler outlet; above 100F means:

a. Increase the cooling water flow. b. Lower the cooling water temperature. c. Back flush and thoroughly clean the intercooler, to restore efficiency.

3. "Blow off" the vessel relief valves to assure their integrity. 4. Test the drain trap assembly and drain the sump at the separator drain of

sludge that may have accumulated by closing off the primary drain until the secondary valve actuates.

All of the above can be accomplished while the dryer is operating.

B. EVERY 4000 HOURS OR 6 MONTHS

1. Perform steps 1 through 4 as outlined in "Every 2000 Hours or 3 Months".




2. Isolate and depressurize the dryer. 3. Disconnect power to the dryer. 4. Replace afterfilter elements (the proper number and quantity is indicated

2. Drain all the desiccant from both vessels through the drain at the bottom of each vessel.

3. Refill both vessels with the proper amount of desiccant as noted in the

specifications at the front of this manual.

NOTE: Desiccant can be purchased only through Ingersoll-Rand distributors authorized to sell Series HC dryers and related products.

4. Make certain all air, electric, and water connections are sound. 5. Open the cooling water supply valve and adjust as required. 6. Repressurize the dryer and place "on-stream". 7. Reconnect power to the dryer.




D. ADJUSTMENTS

The inlet air temperature (as indicated on the Instrument Panel) should be adjusted to obtain the desired temperature/dewpoint performance (reference the Regenerative Dryer Specification Sheet in Section I). This can be accomplished through manipulation of the inlet piping insulation and/or the compressor intercooling.

The temperature of the air leaving the dryer aftercooler should be maintained at or below 90F. Adjust the cooling water supply as required.

4.2 REPLACEMENT / DISPOSAL OF THE DESICCANT

NOTE : Refer to the desiccant MSDS in the appendix of this manual for detailed information regarding material description and ingredients.

The dryer is filled from the top and emptied from the bottom. Refer to the General Arrangement drawing for location of fill and drain ports. To drain the desiccant, remove the drain plug/cover and catch the old

desiccant in a suitable container. Replace the desiccant drain plug/cover. Remove the fill cap and refill the chamber with the specified desiccant. Refer

to the spare parts section for desiccant quantity. Do not tamp the desiccant. Replace the fill cap.

Soap test both fill and drain ports for leaks before returning the dryer to service.



SECTION 4: (Continued) 4.3 DEWPOINT METER MAINTENANCE (DPDS Option only)

NOTE: Refer to the Dewpoint Demand Installation & Operating Guide included with this User Manual for information on dewpoint meter maintenance and operation.

4.4 FILTERS 4.4.1 General comments and use

Filters of the series AF are suitable for filtering solids out of compressed air and other neutral, compressed gases. This new filtration concept is characterized by high flows at low differential pressure.

4.4.2 Function

The soiled medium flows through the filter element "Series AF" from the outside to the inside. Solids are filtered out by impact or by the effect of inertia.

4.4.3 Assembly and installation

Advice The piping system must be cleaned before assembling filter. The filter must always be installed vertically.

4.4.4 Maintenance

Advice The filter element should be replaced when a differential pressure of

> 10 PSID has been reached or, at latest, after 6 months of operation.



SECTION 4: (Continued) 4.4.5 Changing of filter elements

Danger! The soiled filter elements are changed only when the housings are DEPRESSURIZED!

Filter elements are to be changed according to the following steps:

Open the hand hole. Loosen and remove the element by hand. Install the new element and make sure that the element seats perfectly. Re-install hand hole cover. Elements of the AF series can NOT be cleaned with compressed air.

4.4.6 Accessories

Advice Pressure differential gauge: Indicates the degree to which the elements are soiled.

SECTION 6: TROUBLESHOOTING & FAULTS

6.1 INTRODUCTION

Following proper preventive maintenance procedures will go far toward assuring trouble-free dryer performance; however, failures will still occur. This troubleshooting part will help to identify the source of the problem and to effect a remedy.

6.2 HIGH DEWPOINT 6.2.1 Changed Operating Conditions

Check to see that flow rate, pressure, and temperature are still within specification.

6.2.2 Old Desiccant

If the dryer is not able to maintain dewpoint for a sufficiently long period, the desiccant may have aged to the point where its capacity is inadequate. Replace the desiccant with the appropriate quantity and type of desiccant.

6.2.3 Towers Not Reversing

Check PLC, solenoid valve, inlet switching valves, and, if supplied, Dewpoint Demand System meter.

6.2.4 Cooler Discharge Air Temperature Too High

Check cooling water flow rate and temperature. Fouled or dirty cooler may require cleaning on air and/or water side.

6.2.5 Dewpoint Indication In Error

Check calibration/operation of dewpoint measuring instrument.



SECTION 6: (Continued) 6.2.6 Two-way Valve Leakage

Valve leakage here will allow relatively wet inlet air to leak into the dry outlet air stream, thereby raising the dewpoint of the composite air. Compare the dewpoint of the air at the dryer outlet to the dewpoint measured at the top (outlet) of the drying tower (i.e., at the relief valve location). If there is a significant difference in dewpoint, one or both closed 2-way valves is leaking. Check actuator operation and check for seat wear.

6.3 FAIL-TO-SHIFT 6.3.1 Solenoid Valve Failed To Operate

Check electrical connection, coil, and valve seat.

6.3.2 Pilot Air Tubing Leakage

Check tubing fittings for leakage.

6.3.3 Two-way Switching Valve Actuator Leakage

A leaking actuator can cause the switching valve to malfunction; low pilot pressure due to leakage (or solenoid valve failure) will cause the FAIL-TO-SHIFT ALARM to activate. Check for leakage.

6.4 PRIMARY DRAIN FAILURE 6.4.1 Plugging Or Sticking Due To Foreign Matter

If the PRIMARY DRAIN FAILURE ALARM activates, the probable cause is sediment plugging the orifice or impeding the proper operation of the float. Disassemble, inspect, and clean as necessary.



SECTION 6: (Continued) 6.5 SECONDARY DRAIN FAILURE 6.5.1 Solenoid Valve Failure

When the liquid level rises above the primary float valve elevation and contacts the liquid level probe, a circuit is completed energizing the 3-way normally open solenoid valve depressurizing the secondary drain valve actuator. The system pressure should open the secondary drain valve. If the PRIMARY DRAIN FAILURE ALARM activates, but the secondary drain valve fails to open, check the 3-way normally open solenoid valve. Clean, repair, or replace as necessary.

6.5.2 Liquid Level Probe Failure

If the PRIMARY DRAIN FAILURE ALARM does not activate after or during failure of the float operated drain, check the liquid level probe for proper operation.

6.6 SHORT-TERM SHUT-DOWN

Advice

The following sequence is to be heeded when switching off the adsorption dryer: First close all the shut off valves up and downstream of dryer Then immediately switch off the adsorption dryer.

Attention! Dryer will remain pressurized.

6.7 SHUT-DOWN IN CASE OF A FAULT OR FOR MAINTENANCE

Danger! Before any kind of maintenance or repair work is done, the adsorption dryer must be depressurized and disconnected from the power source. Apply the general safety regulations!
