How much money is leaking out of your system?
Using energy in an efficient manner will cut running costs and benefit the environment and as a result
can significantly boost the image of a business in the public eye. With this said, it is essential and clear
that we see the convergence of environmental and business needs are indeed in sync.
We at IAI see this and are working hard to build energy efficient products so both businesses and our
environment can benefit each and every day.
The Industry, Research and Energy (ITRE) Comitee of the European
Parliament has reported that many facilities have no
idea how much their compressed air systems cost on
an annual basis, or how much money they could
be saving by improving the performance of
these systems. Do you know how much
money is leaking out of your system?
The excessive cost of
leaks
An example of how expensive one
small leak can cost, consider the figure
below:
Just one small ¼” hole can cost you € 11000 per
year! Even without a visible hole, pinhole leaks are very
common and add up to a costly energy bill. Energy
costs are skyrocketing and so will the cost of
air leaks that plague most systems.
Leaks can also be a significant
source of wasted energy in an
industrial compressed air system,
sometimes wasting 20-30% of a
compressor’s output. Leaks
will drop system pressure
and make air tools function
less efficiently, adversely
affecting production.
Eliminate your problems with RoboCylinder
You can eliminate costly losses with IAI’s RoboCylinder
electric actuator today! RoboCylinder offers you easy
to use software and all of the benefits of a high-quality
electric actuator. Did you know that the effective
energy efficiency of IAI’s RoboCylinder line is 80-90%,
while a typical overall efficiency is around 10% for a
compressed air system?

Power Consumption Test:
RoboCylinder vs Air Cyli nder
IAI devised a precision power
consumption test procedure to measure
energy efficiency. Both the air cylinder and
RoboCylinder were tested with identical
variables. Variables included dwell time, cost of
electricity, cost of compressed air, speed,
payload, stroke, ambient temp and operating time.
RoboCylinder
Running Costs only
1/3 to 1/10 of an
Air Cylinder
As the operation frequency
increases, the energy requirements
of air
cylinders increase
exponentially, while the power
consumption rate remains constant
with the energy efficient RoboCylinder.
Therefore, the differentials in power
consumption between the two
actuators
increase as the number of cycles per minute
increases. Based on IAI’s calculations, when the
two
actuators are operating at 10 cycles per minute,
the RoboCylinder only requires 1/3 the power of
the air cylinder. When the
actuators are operating at
30 cycles per minute, the difference is even more
profound, with the RoboCylinder only requiring
1/10 the power of the air cylinder! Keep in mind that
no industrial
plant uses just
one actuator;
the more
actuators your
plant requires,
the more
savings and ROI
with energy
efficient
RoboCylinders.
