IT’S NOT PRETTY, BUT IT SAVES A TON OF ENERGY!
As part of our commitment to reducing running costs for our customers, we have developed expertise in plug fan technology that is a simple, yet, hugely effective way to reduce your buildings energy consumption. If you are running an air handling unit of medium to large size, it is well worth investigating the savings in running costs that may be possible when switching from a belt driven fan to a EC ‘Plug’ Fan.
Our client Holy Spirit Hospital found the before and after energy saving data indicates a very short expected payback time. The readings show a drop of close to 36% in energy consumed since changing to the plug fan.
Based on today’s commercial rates, that also equates to a direct saving of approximately $2500 per annum in electricity costs and equates to 8.9 tonnes of reduced greenhouse gas emissions, not to mention reductions in maintenance costs. There are no belts or pulleys to replace and no bearings to grease or motors to align.
How does it work?
EC Plug Fans distribute the air more evenly and closer to the cooling coil.
How does this save energy?
Traditional belt-driven fans need larger starting currents, and more time running to achieve the same air pressure across the coil.
What sort of energy savings have you found?
Old Belt Driven Fan: 30,117kw/h New EC Plug Fan 19,224kw/h. This reduction of -36% equates to approximately $2500 per annum reduction in power costs.
