MOVING WATER
The original plans for the Nissan building called for a pumping system from another manufacturer. The design tem ultimately went with Armstrong’s packaged system.

Above-floor plumbing systems eliminate the need to break through a concrete floor to install drainage below. A macerator or a grinder located behind the toilet reduces the waste into a slurry and pumps it through small-diameter tubing straight to the drain line.

Instead of routing waste through a drain in the floor like a conventional toilet, the macerating toilet flush water is moved to a permanently sealed macerator pump located in a small box between the toilet and the wall. The pump can also be hidden behind the wall. The macerator pump uses a fast-rotating cutting blade to break up waste into a fine slurry that is discharged under pressure through piping and expelled into the sewer or septic tank.

Ryan Hendershott, a licensed plumber with Schreiner & Sons and the installing contractor on the Mid-City job, says the restroom application was well-suited to an above-floor installation. “In theis case. Short of choosing a different location for the restrooms altogether, above-floor plumbing was the least-complicated solution, due to the concrete being there.”

New ended up choosing the Sanibest Pro Heavy-duty grinding system for both the men’s and women’s restrooms. The 1-HP grinder can pump up to 25 feet vertically when it is installed below the sewer line; or nearly 150 feet horizontally to the sewer stack/ It is specifically engineered to handle the accidental flushing of larger sanitary articles and other items a conventional plumbing system might struggle. We want to ensure that anything we flushed, intentionally or unintentionally, got taken care of,” explains New.

 

2controls CONTROLLED LOGIC - Through the Design Assist service, Armstrong was able to optimize the mechanical layout and save an estimated $70,000 in piping costs.

 

NISSAN AMERICA
Franklin, Tenn.

Prior to building the facility the 10-story headquarters office building, Nissan America already operated two assembly plants and a forging plant in Tennessee, so it was an easy decision to locate the new office building in Franklin.

The cooling system called for 1,350 tons of cooling, using two chillers and two cooling towers. Armstrong designed and delivered a complete packaged system including three condenser water pumps, three chilled water pumps. A PFX heat exchanger for free cooling and the IPC 11550, user patented control system, The IPC 11550, uses patented control logic to monitor and adjust the operating speed of each component. The IPC 11550 is constantly adjusting the output of all components to meet HVAC requirements and minimize energy usage.
