Reduce your power use and improve energy efficiency.

Overview

Significantly reduce your operating costs

According to the Energy Efficiency Office, refrigeration and air-conditioning (a/c) is the biggest single user of electricity in the United Kingdom with over £3 billion worth used for these purposes by commercial and domestic users.

The refrigeration industry has, to date, been reticent in discussing the exact running costs of their equipment, although worthwhile improvements have and are being made to improve the efficiency of plant, no particularly effective method of reducing costs has been offered. Now, after many years of continual development, electronic technology is available for use on most refrigeration and a/c equipment in the form of the patent protected savacontrols.

savacontrols provide a viable solution to reduce running costs and are extremely cost-effective with installation paybacks frequently well within two years.

Can they help you?

Your electricity bills, reduced steadily and significantly

Does your business have refrigeration and air-conditioning equipment with AC induction motors? If so, energy costs are likely to be one of your substantial overheads. With savacontrols, you can save money on your electricity bills without replacing your equipment. As well as saving you money savacontrols will effectively also reduce your carbon footprint.

As well as saving money and energy, savacontrols also protect your valuable equipment by reducing energy wastage in electric motors running at low load. But they do not affect the motor’s output nor impair the performance of the equipment in any way by virtually eliminating wasted power. Using savacontrols, refrigeration units run cooler and with less vibration, extending motor life and reducing noise.

From day one, savacontrols save you money on your energy costs. The controls effectively pay for themselves in most cases within a few years. A rapid return on investment is common, ranging from 40-50% the first year.

Applications

Our team can install savacontrols on virtually any AC induction motor. Usually found on…

  • Refrigeration
  • Air-Conditioning units
  • Rocks Crushers
  • Escalators
  • Conveyor belts
  • Mixing Machines

How do they work?

Maintain power loads and save energy

savacontrols reduce power when a motor is under part load, maintaining the same speed. The motor is then able to be operated at full load while saving considerable energy. Motors do not always require the same amount of energy. An uncontrolled motor will keep on drawing full power. Many systems are also designed with unnecessarily large motors to provide a safety margin, and so produce even more waste.

savacontrols constantly monitor the motor load by comparing several parameters such as relative phase angles, the back emf and current drawn. At part load, the apparent voltage to the motor is reduced by cutting the power up to 100 times every second reducing magnetisation loss and drawing much less current. savawatt offers a range of units, including single and three-phase controls to handle up to 250 amps per phase. In low load situations, however, the tests showed a reduction of up to 40% in power consumption. Other tests have shown a reduction of up to 50%. In real-life applications, the average power savings are 20% for single-phase devices, and 15% for three-phase devices.

Installation

Exclusively installed by our trained engineers

All savacontrols are installed exclusively by our own team of trained engineers. savacontrols have a remarkably high level of reliability of better than 99.2% and each carries a full two year guarantee, extendible to five years. We provide expert technical advice and can arrange on-site support at short notice if necessary. Essentially, our technology is “fit and forget”. In addition savacontrols have been performance evaluated by a variety of customers on a wide range of applications. savacontrols have undergone an extensive research and development program to ensure both design and manufacturing improvement.

savacontrols users with these applications include; The Inland Revenue, Superdrug Stores plc, Royal Mail, Nationwide, Manchester United, BP together with many Universities and Hospitals.
