Saving Energy with Variable Speed Drives / Inverters


In the current ecomonic situtation many manufacturers are looking to reduce costs. One simple way to do this is to reduce your energy usage. In the US industrial sector, 70% of all electricity consumption involves motor driven systems. Over 40% goes to centrifugal fans and pumps (like the one pictured). Direct-Industrial.com can help you reduce your energy usage and save up to 60% in these applications by fitting a variable speed drive (inverter) which are now available directly from our online superstore. These drives can be supplied preprogramed with a simple connection diagram so you can start saving money immediately. Pictured below is a Control Techniques Commander SK inverter which we recommend for energy saving applications.




How much can you save?

A centrifugal fan running 24/7, 365 days a year will use well over 10 times it purchasing cost in electricity each and every year. On a large fan that can equate to thousands of pounds per year.

By reducing fan speed by just 20% you will see a 50% reduction in energy consumption. It doesn't take a genius to see that this equates to a substantial cost saving. In fact we recently helped one company save over £6,000 per year with a £900 variable speed drive. Control Techniques (Emerson to anyone in the USA) have a free to use calculator for working out potential savings. You can download the energy saving calculator from here.

  1. My friend who runs a medium-sized manufacturing company recently purchased some high-quality centrifugal fans. Manufacturers, in actual fact, should have ways to save operating costs like electricity, and I'm sure that the inverter can serve this purpose.

    Thanks so much for posting this. I'll let my friend know about this. Good thing he bought his fans from a reputable centrifugal fan manufacturer.
