Energy saving for manufacturing businesses

A successful manufacturing business is all about efficiency

Cut manufacturing energy bills by up to 20%

Manufacturing motors

  • Install variable-speed drives in your fans and pumps
  • Invest in high-efficiency motors, as identified on the government's ETL (or Energy Technology Product List, ETPL)
  • Maintain motor systems by lubricating them and checking the belt’s tightness and alignment

Reducing motor speed by 20% can reduce energy consumption by up to 50%

Compressed air

  • Consider reducing the operating pressure of your compressed air
  • A 1-bar reduction could save about 7% of the energy
  • Switch compressors off when not in use

A compressor that’s left on but not used consumes up to 70% of its full load power

Factory heating and insulation

  • Recirculate the heat created by production lines to warm your premises
  • Ensure your boiler is regularly serviced and tuned
  • Check the insulation on hot and cold pipework and valve flanges
  • Use lids on process tanks, especially out of hours, to prevent evaporation loss

12% of all the energy used by the manufacturing industry is for heating buildings

Factory lighting

  • Encourage staff to switch lights off when they’re not needed
  • Use movement detectors, time switches and daylight sensors
  • Label switches so it’s easy to see which one controls which light
  • Make the best use of natural light by opening blinds in the day
  • Replace traditional light bulbs with LED ones

LED bulbs could reduce the electricity you use for lighting by up to 80%

  • Check door seals – a faulty one could increase a unit's power use by 11%
  • Using too much refrigerant charge can increase energy costs by over 10%
  • Dirty refrigeration condensers can increase costs by around 26%

When buying new refrigerators, AA++ rated units have the lowest running costs
