Aquatherm PP-R Piping Helps Speed HVAC Retrofit at U.S. Candy Company's HQ

Candy factory installers finalPlenty of Demolition

“The available working space was very difficult,” the mechanical contractor said. “This was a total renovation, not a new construction, so it presented some challenges. We had to take the ceiling down and move ductwork and some lighting just to tear out the existing piping. We had some Aquatherm reps that worked with us for a couple of weeks on the fusion part of the installation to make sure it was all set up and done right. It was all done on bench, and we made it up and broke it down each week.”

Because the candy manufacturer’s employees work four 10-hour days each week and are out of the office Fridays through Sundays, the mechanical contractor could perform the retrofit during the three-day windows. “We could go in and shut the system down, drain it, take it apart, install the Aquatherm piping and fittings and put it back in place,” the mechanical contractor explained. “But there were still a lot of unknowns throughout the project timetable: going through offices, walls, floors, moving the furniture, covering everything up, and vacuuming every night as well. And the funny thing is, I don’t even think the employees knew we were there.”

While the facility had some 6-in. steel pipe that was still intact and not leaking, the 4-in. pipe was creating problems; the solution was to replace the pipe and reduce its size by half going into the pump, with 3-in. and 2½-in. Aquatherm Blue Pipe. This downsizing was possible thanks to Aquatherm’s excellent flow rate. (Aquatherm piping systems ranging between 2¼ and 4 in. also were used on the job.)
