With rising energy costs, products offering energy savings are becoming increasingly important. To help businesses reduce energy usage, Fairford have developed a range of energy saving products.
The vast majority of electric motors in use today are fixed speed, fixed voltage AC induction motors. These motors consume two thirds of the total electricity used in industry. With this in mind, using a technology that could save energy on fixed speed induction motors should be a consideration when replacing motor starters or designing new systems.
Energy recovery with Internal bypass as standard
iERS is our patented energy saving system with a combined internal bypass to save energy on lightly loaded motors. iERS reduces the voltage and current supplied to a lightly loaded motor to only allow the motor to consume the exact amount of energy required to maintain the speed at that load. When the motor is at full load the internal bypass reduces the losses produced by the control element. This combined approach enables iERS to save more energy in more applications than any other competing technology.
iERS has been market proven over the past 10 years and has now reached its latest development realising even greater savings. Applications such as fans, pumps and chillers can typically see savings of around 8-40% of total energy consumption.
How it works
airford’s energy saving system works by reducing the current and iron losses of a motor not running at full load. The energy savings will depend on a number of factors including the efficiency of the motor and the load.
Fairford Soft Starters will also save businesses money by reducing the electrical and mechanical strain placed on applications – resulting in less ‘down time’ and maintenance cost on electrical circuits, gearboxes, belts and associated mechanical components.
