Motors
Keep your motors maintained
If a motor isn’t working at its most efficient, it can add 5% or more to your energy costs. So make sure yours are always well maintained.
Use high efficiency motors
When you next change your motor, replace it with a Higher Efficiency Motor. These can qualify for tax relief as part of the Enhance Capital Allowance scheme.
Don’t keep motors running with an empty load
Always check that motors are switched off when you don’t need them, as even an empty motor uses 40% of the full load power.
Compressed air
Find and fix leaks
Most businesses using compressed air can save up to 30% simply by fixing any leaks.
Try to lower the operating pressure
Reducing it by just 1 bar (15 psi) will save about 7% of the energy.
Ensure there is a good supply of cool air around the compressor
This will ensure it doesn’t get overheated and use more energy than necessary.
Refrigeration
Keep freezer doors closed
On average, it will cost you £6 every hour a freezer door stays open.
Ensure your system is at the right temperature
If it’s even 1ºC lower than needed, your costs could rise by 2-4%.
Don’t let the condensers get overheated
Make sure they are located in a place with sufficient airflow.
Don’t put too much refrigerant charge in
If it leaks it can increase your energy costs by over 10%.
