There are various ways in which you can cut your manufacturing energy prices. Below, we’ve outlined just some ways in which you can keep costs lower.
Try to incorporate as many of these ideas into your energy-saving strategy for a potentially bigger payoff. There may be instances where it is possible to shave off as much as 20% on your gas and electricity bills.
Manufacturing motors
When it comes to motors, you want to use variable-speed drives in both your fans and your pumps. You will also want to consider high-efficiency motors and ensure they are well-maintained and cared for. Motor systems should be lubricated, and the belt’s tightness should be checked, adjusted and realigned when necessary.
One of the best forms of waste management when it comes to energy is reducing motor speed. Even lowering the speed to just 20% of what it currently runs at can reduce consumption in the manufacturing industry by up to 50%.
Compressed air
If you use compressed air, think about whether you can lower the pressure as it operates. Even something as little as a 1-bar reduction can have a decent effect on your energy bill.
Ensure compressors, when not in use, are turned off. This is because they can use almost three-quarters of their energy consumption when left on.
Heating and insulation
If your business involves a production line, it’s possible that you can recirculate the heat created by it to warm your warehouse/premises. It’s also a great idea to ensure your boiler is well-maintained and serviced yearly. You should also check the insulation on valve flanges and both hot as well as cold pipes.
Factory lighting
Actively encourage your staff to be mindful of their energy usage. Remind them to turn lights off after themselves and offer small incentives for doing so.
You might also want to consider the use of movement detectors or light sensors which will automatically switch off when they aren’t needed. You could also think about trying to use natural light more, if appropriate. Something as simple as keeping the blinds open during the day can often limit the energy costs of electricity.
One of the best ways to implement low-cost measures is to use LED bulbs over regular bulbs. Using these can reduce the amount of electricity required by 80%.
Refrigeration
Refrigeration is another area of your manufacturing business that could potentially waste a lot of energy. Ensure you check door seals. If you have a faulty seal, you can be certain this is costing you money. A faulty door seal can increase a refrigeration unit’s energy usage by up to 10%.
Also, ensure you aren’t using too much refrigerant charge. Doing so can amount to an increase of 10% on your bills.
When the time comes to purchase new refrigerators, look for those that are AA++ rated which will have the lowest running costs.
