Lake Louise Inn

Commercial laundry in beautiful Banff

Alberta, Canada

Lake Louise Inn (LLI) is a 247 room resort nestled within the breathtaking Rocky Mountains in Banff National Park, part of a UNESCO World Heritage Site.  

Utilizing a PIRANHA T10 to collect the hot wastewater discharge from their laundry systems, Lake Louise reduced their laundry water heating energy demand by as much as 45%.

Their PIRANHA T10 wastewater heat recovery system intercepts laundry room wastewater, extracts heat from it and uses that heat to offset the energy required by the hotel to heat water for the laundry.

"Our PIRANHA works great and is reliable, I’ve definitely noticed how much less our boilers run because of the reduced load. We love showing our Guests that we take actionable steps towards green energy."
