INTRODUCTION

1.1 GENERAL INFORMATION

The adsorption dryer of the HC-3 – HC-239 series is built according to the latest

technological developments and recognized safety rules. Its use, however, can

endanger life and limb of the user or of third parties and can lead to considerable

damage to the adsorption dryer and other material assets if:

 it is operated by personnel not trained or instructed in its use,

 it is improperly used,

 It is improperly maintained or serviced.

This can result in the loss of all damage claims.

This adsorption dryer is designed for neutral media (gas) free of aggressive water,

oil and solid elements.

1.2 SAFETY INSTRUCTIONS

This technical manual contains basic tips, which must be followed during set-up,

operation and servicing. It is of utmost importance that it be read by the assembly

technician before installation and start-up, as well as by the specialist / operator in

charge, and it must always be within reach at the place where the adsorption dryer

is being used.

1.2.1 Identification of signs and symbols in this technical manual

The safety tips contained in this technical manual, whose disregard could endanger

people and machines, are indicated by a general danger sign and the additional

markings Danger! or Attention!

Danger! / Attention!

Warning against electrical voltage!

Safety tips printed directly on the adsorption dryer must also be followed at all times

and must be kept completely legible.

 Advice: This sign refers to a procedure or sequence of particular

interest or importance. All tips must be followed to ensure

proper use of this adsorption dryer.

 This dot refers to working or operational steps. The steps are to be carried out in

the order of their appearance from top to bottom.

- The sign of a hyphen marks enumerations.

1.2.2 Safety tips for maintenance, inspection and assembly work

The operator is to make sure that all maintenance, inspection and assembly work is

carried out by special personnel who are authorized and qualified, and who are

adequately informed through careful study of the technical manual. For this reason,

special attention should be paid to the following attention and danger sign:

Attention!

 Never make structural changes to the adsorption dryer that are

not specifically authorized by Ingersoll-Rand!

 Only use original spare and accessory parts!

 Carry out maintenance work only when the adsorption dryer is

switched off, depressurized, and disconnected from the electric

power supply!

Attention!

 Multiple power sources may exist in the electrical panel. All

possible power sources must be disconnected before servicing

dryer.

 Advice: Refer to the desiccant material safety data sheet (MSDS) when

installing or disposing of desiccant, which can be found in

Section 8 of this User Manual.

Danger!

Wear protective goggles and mask when working with the desiccant!

 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.

Danger!

Do not attempt to service or maintain dryer while system is hot!

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.

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 (Dew Point Demand System) is optional equipment and may or may

not be present on this particular air dryer. If the dryer is equipped with the DPDS,

see the associated DPDS Instruction Manual included in Section 7 for more

operational details.

The regeneration cycle is split up into three functions.

USER MANUAL

Reference IR - 222 Rev 3

Page 12 10/17/2013

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

dew point. The heating cycle lasts 90 minutes.

USER MANUAL

Series HC

Reference IR - 222 Rev 3

Page 13 10/17/2013

SECTION 1: (Continued)

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. If dryer is equipped with optional trim heater,

reference operational instructions in Addendum at back of manual.

Series HC

Reference IR - 222 Rev 3

Page 14 10/17/2013

SECTION 1: (Continued)

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.

1.4.3 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.

To correct for a cooling water temperature other than 85F, or an operating pressure other than

100 psig, multiply dryer capacity by the correction factors listed above.

Example: To size for an inlet flow of 2208 m^3/hr @ 6.2 Bar, using 32



C cooling water:

Multiply 2208 * (1.1) * (1.2) = 2914 Use Model HC-21
