Ingersoll Rand India Private Limited was founded
in Kolkata in 1921, one of the first American
investments in India. In 1958 the company opened
a branch office in Ahmedabad and in 1963 the
head office was shifted to Mumbai. I0ngersoll
Rand established its first manufacturing plant in
Naroda, Ahmedabad in 1965 and in 1977 became
a public limited company.

With a major emphasis on ‘Innovation’ to drive
‘Productivity’, the company has had many firsts to
its credit. Ingersoll Rand is a pioneer in bringing
centrifugal technology into India and started
manufacturing CENTACS (Centrifugal
Compressors) way back in 1989 when centrifugal
technology was hardly known and accepted. In
recent times, with the focus shifting to energy
efficient compressor technology, Ingersoll Rand
launched the award-winning ‘Nirvana’ energy
saving rotary compressors. The company
continues to bring latest technologies to India and
launch localized products keeping in mind the
requirements of the Indian market. Not just path-
breaking technologies and products, Ingersoll
Rand’s key strength is its world class service that it
provides to its customers across the country.
Today, Ingersoll-Rand (India) Limited is based out
of 22 locations in the country and is listed on the
National Stock Exchange of India and the Bombay
Stock Exchange.
Ingersoll-Rand (India) Limited has recently rolled
out an aggressive plan for growth in India. The
foundation of this growth will be customer driven
innovation, a robust infrastructure to support after
sales services, a significant investment in the

facilities to transform them into world class
manufacturing operations and a ‘Customer First’
and ‘Solutionizing’ mindset.
Compressor is a device used to increase the
pressure of compressible fluid, either gas or
vapour, by reducing the fluid specific volume
during passage of the fluid through
compressor. One of basic aim of compressor
usage is to compress the fluid, then deliver it
to a higher pressure than its original pressure.
The inlet and outlet pressure level is varying,
from a deep vacuum to a high positive
pressure, depends on process’ necessity. This
inlet and outlet pressure is related,
corresponding with the type of compressor and
its configuration. As shown in Figure 1,
compressors are generally classified into

two separate and distinct categories:
(i)dynamic and (ii)positive displacement.
Positive-Displacement
Compressor
Positive displacement compressors deliver a fixed
volume of air at high pressures; it
commonly can be divided into two types: rotary
compressors and reciprocating

compressors. In all positive displacement
machines, a certain inlet volume of gas is
confined in a given space and subsequently
compressed by reducing this confined space
or volume. At this elevated pressure, the gas is next
expelled into the discharge piping or
vessel system.
(I) Rotary Compressors
Rotary compressor is a group of positive
displacement machines that has a central,
spinning rotor and a number of vanes. This device
derives its pressurizing ability from a
spinning component. The units are compact,
relatively inexpensive, and require a
minimum of operating attention and maintenance.
In a rotary compressor, the pressure
of a gas is increased by trapping it between vanes
which reduce it in volume as the impeller
rotates around an axis eccentric to the casing. It is pictured;

The volume can be varied only by changing the
speed or by bypassing or wasting some of
the capacity of the machine. The discharge
pressure will vary with the resistance on the
discharge side of the system. Rotary compressors
are generally classified as screw
compressor, vane type compressor, lobe and scroll
compressor. The main difference
between each type is their rotating device. The
advantages and disadvantages of rotary compressor
are shown in a table below;
ADVANTAGES
1. Simple design High rotational speed

2. Low to medium initial and maintenance
cost
3.Two-stages design provide good
efficiencies
4. Easy to install
5. Few moving parts
DISADVANTAGES
1 .High rotational speed
2 .Shorter life expectancy than any other
designs
3 . Single-stage designs have lower efficiency
LOW INDUSTRIAL SEGMENT [LIS] :
[ 4KW – 37 KW ]
MEDIUM INDUSTRIAL SEGMENT
[MIS] :
[ 37 KW – 300 KW ]

WORKING OF ROTARY COMPRESSOR :
Rotary screw air compressors are the most widely used
air compressor models in the industrial marketplace.
Rotary screw compressors provide continuous

compressed air for precision tasks and they are
extremely efficient and remarkably quiet. Screw
compressors utilize some of the most advanced
technology available in the compressor industry and
have a very low energy consumption. These machines
are built to run 24 hours a day, 7 days a week, for
many years!
The power (and name) behind these remarkable
machines comes from two counter-rotating screws
which are housed in a chamber, formally known as an
airend. Outside air first travels through a filter to catch
any harmful particles and debris that could cause
damage. Once filtered, the air goes through an inlet
valve and into the space between the interlocking
screws. As the rotors turn, the air moves along and
travels to the other end of the compression chamber.
The area in which the air is contained gets increasingly
smaller as the air moves along, and the smaller space
increases the pressure. This process is one smooth
continuous motion, and therefore produces minimal
pulsing or surging which can occur with piston

compressors. The result is a high-volume, steady
stream of compressed air.
Oil-Injected
In an oil-injected rotary screw air compressor, the oil
serves five key purposes: it cleans, cools, lubricates,
seals, and protects. Therefore, what is produced by the
airend is a compressed air/oil mixture. This mixture
flows into a separator tank where the two are, well…
separated! Primarily, a mechanical separation takes
place using a filter. Further, oil can be removed using
centrifugal force or a rapid change in direction. In the
case of centrifugal force, rapid spinning allows the
heavier oil particles to drop to the bottom while the
lighter air spins around on top. Simultaneously, the
separated elements leave the tank.
The air leaves the tank and travels through a minimum-
pressure valve, and (in some cases) a cooler. The
minimum-pressure check valve is dual-purpose and
ensures there is sufficient air pressure for proper
operation while also working to keep the air pressure

from coming back into the system so, when necessary,
the motor can start without a load.
Oil-free rotary screw compressors
The basic workings are the same as the oil-injected
screw compressor, only this time, there’s no oil, only
air! Because there’s no oil injected during compression,
the compression is usually done in two stages. Because
if we would compress the air in one go from 1 to 7 bars,
it would get really, really hot.
Stage one compresses the air to a few bars (say 2,5
bars). The air will be very hot at this time, so it flows
through an inter-cooler first before entering the second
stage. Stage two will compress the air further from 2,5
bar to the end-level, mostly 7 bar.
Normally the two stages will be built on 1 gearbox,
with one electro motor driving them at the same time.

1. Air Filter :
A particulate air filter is a device composed of fibrous
materials which removes solid particulates such
as dust, pollen, mould, and bacteria from the air
2.Oil Filter : An oil filter is a filter designed to
remove contaminants from engine oil, transmission
oil, lubricating oil, or hydraulic oil. Oil filters are used
in many different types of hydraulic machinery. A chief
use of the oil filter is in internal-combustion engines in
on- and off-road motor vehicles, light aircraft, and
various naval vessels.

3.Pressure Switch : A pressure switch is a form
of switch that closes an electrical contact when a
certain set pressure has been reached on its input. The
switch may be designed to make contact either on
pressure rise or on pressure fall.

4. Safety valve :
Safety Valve is a one type of valve that automatically
actuates when the pressure of inlet side of
the valve increases to a predetermined pressure, to open
the valve disc and discharge the fluid ( steam or gas ) ;
and when the pressure decreases to the prescribed
value, to close the valvedisc again.

5.Solenoid valve :
Solenoid Valves have one inlet and one outlet, and are
used to permit and shut off fluid flow. The two types of
operations are “Normally Closed” and “Normally
Open”. ASCO 3-WaySolenoid Valves have three pipe
connections and two orifices. When one orifice is open,
the other is closed and vice versa.
6. Inlet valve :

The unloader or inlet valve regulates the capacity of
your rotary screw compressor.The air compressor unloader
valve regulates the ammount of air that is sucked in by
your air compressor. By opening and closing the air intake,
the capacity of a rotary screw compressor is regulated.This
valve is also commonly called an inlet valve or an intake
valve

PROJECT 3 To layout the
map of LIS Rotary assembly area and
find out the standard work done
in/between the main flow line
stations.
MACHINE 1 : INFINITY
[15 KW , 7 BAR]
1. Lot of conjusted (spider web,as seen from
given layout) Manwork observed during the
path of Cooler Assembly and Main flow
lines.

2. There is no work done at Evolution
Aseembly. Therefore this area/space is not
much used during assembly of this model of
machine.
3. In INFINITY model,use of crane is
observed less and Manwork is more(as seen
from layout).
4. In Main station 3 , for fitting of cooler 2
persons are required,which implies a man
working at station 3 needs assistance from
station 2 or 4,thereby increasing movement
between stations.
5. There is not much movement observed
between Kitting Trolley and Main flow Line.

6. There is no separator tank introduced in this
type of model.
7. Assembly of front cover of this model is
done on Cooler Assembly station.

[15 KW , 7.5 BAR]
1. There is equal distribution of movements
observed between all stations in this model as
compared to that of Evolution and Infinity.
2. Use of crane is more during assembly of this
model of rotary compressor.
3. Airend Pulley has to be heated at station 3 for
proper installation,Therfore a person has to
take pulley from Kitting trolley and travel to
place where Induction Heater is placed and
heat it,and again come back to station 3 and
assemble it. This route seems to be interfering

with other stations as well.So this needs to be
Eliminated.
4. There is uniform flow of Kitting Trolley
observed in this case of model.
5. There is movemet observed between Storage
area and Main Flow Stations 1and station 2.

[ 30 KW , 7 BAR ]
1. No STANDARD KITTING TROLLEY is
provided for this special model. Therefore
special trolley( Non standard trolley) is
used in which all fabrications parts are kept.
2. Complete body of this model ( ie canopy) is
placed near Evolution Aseembly
Staation,which is further assembled at
station 4.
3. There is lot of movement observed ( as seen
from the given layout) between Evolution
assembly station and the Main flow Line
Stations.

4. Use of Crane is seen more in this type of
Evolution Model.
5. There is no movement ( ie now work done
on cooler assembly station ) between
Cooler Assembly station and Main Flow
Line Station.
6. In this model Airend is installed in Station
2, whereas Separator Tank in station 3.

[ 5.5 KW , 7.5 BAR]
1. Use of Crane is minimum in this type of
Evolution Model.
2. Man work is observed to be more.
Therfore there is a lot of movement in
between Main Flow stations.
3. There is no use of Cooler Assembly
station in this model ( ie. no work is done
in this station).
4. Here controller is kept in KITTING
TROLLEY and not on Controller skit as
in other models of LIS.
