Re: Energy Saving with GATES Synchronous Belts. We understand that your company is actively involved in reducing its electrical energy costs and carbon dioxide (CO2) emissions.

Following you will find a short presentation which outlines how significant energy savings can be achieved by replacing flat or Vee belt drives with synchronous belts. This is most effective in pump, fan (A.H.U.’s & production), and compressor applications. The belts are available from our Gates appointed distributor, E. Fox Engineers. We would welcome an opportunity to visit your facility and examine a relevant application to demonstrate the savings you could achieve. Please see the worked example in the following presentation of the cost savings possible.

I will phone you shortly regarding the above, but in the meantime should you have any queries about Gates products and their energy saving qualities, please do not hesitate to contact me.

POLY CHAIN®The unique Power Transmission Drive.

Saves significant energy

Increases bearing life on both driver (motor) and driven fans, pumps, and other applications.

No maintenance required – fit, tension correctly, and forget for its calculated life.

Operates in extreme conditions where lubrication is not possible.

Provides the highest power to size ratio of all power transmission drives.

Drives are made more compact through the use of Poly Chain® because of its size to power ratio.


Positive Drive:

Energy savings using synchronous belts Synchronous belts are recognised as significantly more efficent than Vee belts or flat-belts. Replacing a Vee belt drive with a sychronous belt drive will increase efficiency and give pay back after a period of 6 months or less.

A synchronous belt is a positive drive with losses of less than 0.5%


A Vee Belt should be:

Tensioned at fitting Tensioned after one hour Tensioned after one day Tensioned after one week Tensioned after one month Tensioned after six months Replaced after twelve months.

Should this best practice not be used energy losses of up to 20% can be expected.

In applications such as fans, pumps and compressors, further losses can occur where slip can effect the expected flow of air or liquid.

Consistent Performance:

When fitted and tensioned properly the performance of the Poly Chain® will last for the duration of the belt’s life - three years for 24 hours per day, or 25,000 hours - without ever being re-tensioned, reducing maintenance time and costs..

Bearing losses:

Because of near zero slack, synchronous belts create less axial and radial loads on bearings, resulting in longer bearing life and improved efficiency.

Load sensitivity:

Synchronous belts are less load sensetive whereas Vee belts are highly load dependant.



An example of Poly Chain® working under extreme conditions.

The Poly Chain® replaced roller chain which was wearing out within two weeks.

Conditions in this concrete plant made lubrication impossible because the combination of dust, water, and lubricant formed a grinding paste.

The Poly Chain® installed in November 2004 and is still running in March 2005 without maintenance or wear.
