Your industrial site

Your industrial site may be running efficiently, but there are always ways you can tune up your processes, equipment, and the way your staff use your kit. Here are the places to start.

Motors and drive systems

Image of motor system

Service gearboxes regularly and replace standard V-belts when required, bypass soft starter units and install high-efficiency motors.

  • Install high efficiency motors
  • Replace standard V belts with cogged or synchronous belts
  • Regularly service gearboxes
  • Turn equipment off / reduce standby losses

Pumping systems


Replace pumps when needed, install level controls and pump impellers, consider variable speed controls.




If your business has high cooling costs, efficient refrigeration can yield major savings. Food retailers and meat processors use about two thirds of their electricity for refrigeration. In the wholesale food sector, that figure can be more than 85% of total energy use. Save 15% through changing to efficient use and maintenance, and save 40% of energy used by upgrading, replacing and rationalising equipment.


  • Reduce air infiltration rates
  • Investigate cooling loads
  • Consider 'free' cooling alternatives
  • Inspect and repair insulation
  • Improve defrost cycles


  • Reduce discharge pressures
  • Increase suction pressures
  • Optimise compressor capacity controls
  • Clean condenser/evaporator coils
  • Use booster compressors for multiple temperature levels
  • Consider heat recovery options
  • Investigate peak load shedding options

Investigate variable speed drives (VSD) and isolate circuits when not required.


  • Isolate circuits when not required
  • Investigate variable speed control
  • Investigate fan suitability for requirements

Boilers / process heat

Regularly tune boilers (6 monthly) to maximise efficiency, investigate opportunities to recover heat, and options for switching to wood energy. 




  • Insulate end users, lines and valves
  • Optimise heat energy use
  • Reduce operating temperatures 


  • Regularly clean and tune burners
  • Reduce supply pressure/temperature
  • Consider alternative fuel sources
  • Turn boilers off when not required
  • Consider heat recovery options 
  • Conduct regular boiler combustion efficiency testing
  • Clean boiler at regular intervals
  • Consider switching to wood energy when replacing boilers,
  • Install flue gas isolation dampers

Compressed air

About 85% of energy used to run an air compressor turns into heat. So it’s worth exploring ways to use this waste heat, like ducting hot air from cooling vents to working areas and using a heat exchanger to heat water.


  • Identify and remedy compressed air misuses
  • Identify and repair compressed air leaks
  • Improve sequencing controls
  • Reduce compressor pressure setpoints
  • Reduce distribution pressure drop
  • Improve capacity control and intake design
  • Consider heat recovery options

Staff facilities

Regularly check staff facilities like ovens, fridges and pipes for leakage and ensure temperatures are set for safety and efficiency.


  • Use timers and thermostats on hot water boilers and boiling water dispensers
  • Set hot water cylinders to 60oC, and 55oC at the tap
  • Check seals on fridges and ovens, and thaw fridges and freezers regularly
  • Repair leaking water boilers
  • Install light sensors or timers in kitchen and bathrooms

Image of insulation

Install ceiling and floor insulation, in areas you heat and cool. Repair seals on external doors and windows. Wrap your hot water boiler and piping with pipe lagging.

  • Install ceiling and floor insulation, in areas you heat and cool
  • Draft-proof external doors and windows
  • Wrap your hot water cylinder if it’s slightly warm to the touch
  • Wrap the first few meters of hot water pipe from the cylinder, high use hot water pipes and external hot water pipes with pipe lagging

Image of lighting

Install movement-sensitive sensors and timers to ensure lights are only on when needed. Switch off after hours, leaving only enough to ensure security. Switch to LEDs, and use natural light.


  • Install sensors and timers to ensure lights are only on when needed
  • Install movement-sensitive light switches in areas of low use
  • Switch off after hours, leaving only enough to ensure security
  • Replace incandescent bulbs with energy efficient lights like LEDs, especially those used for more than 4 hours per day
  • Make the best use of natural light by opening blinds and installing skylights

Computers and monitors

Turn off computers and other equipment not in use - this saves energy and prolongs the life of your equipment.


  • Switch off computers and monitors when not in use, or install power-saving software

Heating and cooling

Set temperature to suit each space and the equipment and processes you use.


  • Timers on lights, hot water, boiling water dispensers, air conditioners and heaters make sure energy isn't wasted
  • Set the temperature to suit each space – check the thermostats on devices that have them, and ensure setpoints suit the processes you use
  • Remove desk heaters and fans
  • Clean air conditioning filters to ensure maximum efficiency
