Project Details

Lighting

The old lighting inside the freezers was replaced with new LED fixtures, giving all the products inside a very crisp, clear and more appealing “look”. Also, existing 500W halogen exterior lights were replaced with brand new 24W LED flood lights, yielding a whopping 476W reduction per fixture while maintaining visibility levels!

Refrigeration

All of the freezers/coolers were powered by older model “shaded-pole” motors which ran at a constant 140W. Twin Supplies was able to replace these energy hogs with new EC-Motors which, thanks to the use of a controller, consume only between 9W and 40W! Through the use of a controller with two sensors, the system is able to detect when the motors need to be working at full speed (40W) or when they can be set to the lower speed (9W). These motors run at 9W nearly 90% of the time, saving the end user a significant amount of energy. This replacement did not involve any changes to the compressor or anything related with the refrigeration system itself besides the electric motors. The second measure involved adding strip curtains inside of walk-in coolers and freezers. The advantage of the strip curtains is immediate – anytime the door is open, particularly for an extended period of time like during a delivery, the strip curtains keep the majority of the cold air inside the compartment and the hot air out, preventing overworking of the unit and energy waste. Finally, a third and very simple measure involved adding a door closing mechanism for the freezer and cooler doors, which ensures that the door remains fully and firmly closed, keeping air from leaking in or out.

The customer was thrilled with the job and has now permanently reduced energy consumption, resulting in lower energy bills. Please feel free to contact us for a free, no obligation audit at your business, where we can provide a detailed energy savings proposal to you!
