Grundfos Gets Underneath Canada’s Tallest Hotel Tower

Overview

Hilton Hotel and Suites located near Niagara’s famous Horseshoe Falls underwent a $150-million transformation to become Canada’s tallest hotel tower. The 500-room, all-suite tower required an HVAC and booster system that would be reliable and energy efficient. Most importantly, the booster system had to boost water to the top of the 53-story building.

Smith + Andersen was the engineering firm who designed the mechanical systems to do the job. When it came time for E.S. Fox Ltd. to choose a supplier, the reliability and energy efficiency of Grundfos pumps was the determining factor.

The HVAC system installed consists of UP, UPS, TP pumps and PACO pumps, with motors ranging from ¾ hp to 50 hp. This combination of pumps was chosen for their reliability for the following reasons:

  • The UP and UPS pumps are maintenance-free, have no bearing, seal or coupling. This will save the owner future maintenance costs.
  • The TP pumps are epoxy coated, have a wear ring and an SS impeller. The pumps will operate cleanly and reliably for years, and when it comes time to repair a pump, the wear ring can be replaced to return the pump to a “like-new” condition.
  • The PACO pumps have a double volute, wear ring, inside mechanical seal and suction splitter. Seal repairs will be less frequent, and when they are required, they will be half the cost of a repair for a pump that has an outside mechanical seal.

The three pump BoosterpaQ pumping system installed consists of CR vertical inline multistage pumps for variable speed operation, with 40 hp motors. The operating set point is 250 psi and 675 gpm. The BoosterpaQ system was chosen for the following reasons:

  • The multi-pump controller (MPC) alternates between the lead and lag pumps. This feature, in combination with the pumps running at a slower speed, extends the life of the pumps and reduces maintenance costs.
  • The pumping system is variable speed for energy savings. Additional savings are accomplished due to the high efficiency of the Grundfos pumps.
  • The package includes a corrosion-free stainless steel base frame, panel brackets and manifolds, which make for reliability, durability and cleanliness.

Both the HVAC and BoosterpaQ systems were installed between May 2008 and May 2009. There are 37 pumps in total and since the project’s completion they have been working extremely reliably. The only service issue has been a single seal failure, which is remarkable for the number of pumps installed.
