Prior to installing new XLERATOReco Hand Dryers throughout the campus, Dan Fernbank, Energy Manager at the University of Reading, reviewed independently verified energy performance data of various high-speed hand dryers.
Using the Salix Finance hand dryer calculation tool and the Carbon Trust’s Energy Technology List, Fernbank determined that the XLERATOReco Hand Dryer was the best option for the university.
“We conduct research about climate science and sustainable construction, so we need to lead by example. Manufacturers like Excel Dryer – who continue to innovate sustainable products like the high speed, energy efficient XLERATOReco Hand Dryer – allow us to do that,” said Fernbank.
Reading previously used conventional hand dryers with 30 – 45 second dry times, which consumed approximately 2,400 watts when in operation, according to the Salix calculator. For 72 conventional hand dryers, the total energy used was 81,664 kWh for an estimated lifecycle of 64,000 hand dries.
Fernbank compared the conventional calculations to the UK blade-style hand dryer and the XLERATOReco Hand Dryer manufactured by Excel Dryer. The UK blade style hand dryer used 1,600 watts when in operation with a total of 21,098 kWh of energy, according to the Salix calculations.
12 Seconds Hand Drying Solution
The high-speed, energy-efficient XLERATOReco Hand Dryer, however, uses innovative technology to dry hands in 12 seconds* using only 500 watts, making it the most energy-efficient and environmentally friendly hand dryer on the planet. According to the Salix calculator, the XLERATOReco dries the same number of hands with a total energy use of only 9,526 kWh, 55 percent less energy than the UK blade-style hand dryer. The XLERATOReco represents an annual energy savings of 88 percent for the university, compared to an estimated 74 percent annual energy savings for the university if they were to install the UK blade-style models.
With the installation of 72 XLERATOReco Hand Dryers, the university will realize an additional 16% annual financial savings over the UK blade-style hand dryers (£9,053 savings, compared to £7,601 savings).
“This independent research provided assurance. Someone has looked at each of these machines and come up with how much energy they would use,” said Fernbank. “The research supported the XLERATOReco Hand Dryer for the long term. This was a good opportunity to go beyond what had been done in the past and make some additional savings.”
High Traffic Demands High Speed
The units were installed in washrooms with a fluctuating level of traffic, and as a result, the number of hand dryers per washroom varies. “Depending on the space, there could be anywhere from one to six hand dryers per washroom. Some, like our Student Union are very high traffic indeed,” Fernbank said.
The Reading University Students’ Union – a one-stop-shop for everything from meeting rooms to restaurants, and bars to campus shops – is home to several high speed, energy efficient hand dryers.
Despite being housed in high traffic areas, the XLERATOReco Hand Dryers have proven to be a reliable investment for the campus. “One of the attractions of the models is that they look robust and came with a good guarantee, which was pretty reassuring,” said Fernbank, who added that the Estates & Facilities department at the university has requested more hand dryers be installed in new buildings around the campus. “People have seen how well it’s worked to help us save energy and want to do it again.”
“The key for us, when you look at all the purchases we’ve done, is that this is definitely the one we’re getting the best payback on in terms of the amount of energy we’re saving for the investment we made,” said Fernbank. “This is a key component to our green initiatives that we plan to roll out in many more places across the university.”
