Integra Energy Saving Solutions


Renmar is aware that the cost of running a production or recycling facility is a vast expense and we wanted to find a way to assist our customers in reducing those costs. One easy way to save on your running costs is by reducing your energy bills.

Teaming up with Suresense Technologies, Renmar can now provide you with just the way to make energy savings with the Suresense Integra unit for intelligent fixed speed motor control.

The Integra units are compatible with conveyors, crushers, granulators and shredders.

The Problem –

If you use electric motors you could benefit from Integra from Suresense.

Energy can be a significant cost in the production of most of the products we purchase. Approximately 65% of all energy in industry is consumed by AC induction motors and approximately 10% of all these motors are operating in applications that require variable speed conditions.

However, the vast majority need to operate at a single or fixed-speed but installing a variable speed drive onto a fixed speed application is not recommended. It can increase the running cost by as much as 6-8%. The loading on a motor during the typical duty cycle can fluctuate dramatically, ranging from 0-100%. While there is a measure of reactance within the motor windings, the motor has no way of intelligently adjusting the amount of power it consumes in relation to the job of work it does. Wasted energy is converted to heat, vibration and noise.

The Solution –

Integra is a range of intelligent controllers for fixed speed motors and are suitable for many motor sizes and applications; Integra provides an extensive array of special application pre-sets and easily configurable parameters.

It combines world leading soft start, intelligent load monitoring, energy optimisation and controlled stopping in a smartly designed, easy to install and competitively priced unit.

In effect; Integra electronically ‘re-sizes’ the motor to both its application and load cycle every 10 milliseconds. Integra is perfect for fixed speed applications because motor rpm is maintained at all times. Integra can also be configured to turnoff the motor when no load is detected.

Integra can extend motor life, reduce maintenance costs and save a fortune in the process. Payback is normally achieved within two years, sometimes just a few months.

How It Works –

Cruise control on a car will intelligently adjust the amount of power being produced by the engine in order to maintain a fixed speed. Integra can do the same for your motors and save 10% - 40%. It achieves this by converting the motor into its own load sensor to ensure that it uses the exact amount of energy required to do the job of work at any instant in time, no more – no less!

In effect Integra ensures that the motor runs at optimum efficiency throughout the load cycle by constantly monitoring and controlling torque. This means that the full load capability of the motor is never compromised. The motor can still draw full power when required in 50th of a second but at partial loads, particularly below 50%, significant savings can be achieved. Integra is perfect for fixed speed applications with variable loads because the exact synchronous speed of motor is maintained at all times.
