This university needed a leaking HVAC system rehabilitated in-place during its one-week spring break, and Nu Flowwas up to the challenge. The pipes were effectively cleaned and lined without causing any destruction or disruption
to normal school operations.
Project: Use Nu Line to
rehabilitate the failing HVAC lines
in-situ.
Site: A southern California public
universitys science building. This
3-story building was constructed
in 2002 and holds science
classrooms, laboratories and
staff ofces.
System: 650 feet of black steel
pipes that make up the HVAC
chilled water system for the
building. The 6"-wide pipes are
located above the ceiling of
the rst oor, behind re rated
drywall ceiling.
Problem: The black steel pipes had water corrosion and MIC build-up, which caused leaks throughout the system.
Also, the school wanted the work done during spring break, so there was a very tight schedule.
Circumvention: If the university had chosen a traditional pipe repair instead of Nu Flows in-place solution, thescience building would have been closed off to students and faculty during the normal school year. The re rated
drywall ceilings would be opened, causing a messy destruction site and expensive repairs.
Solution: Nu Flows most skilled Nu Line technicians
completed this project within the short timeframe. The
pipes were cleaned and then the epoxy was applied to the
pipe system. This epoxy barrier coating will prevent future
pinhole leaks, corrosion, MIC build-up and other common
failures. This process was completed using two small
existing access points at the beginning and the end of the
pipe system. Nu Flows non-invasive solution prevented
the need for destruction or building closure. Preserve yourproperty with Nu Flows in-place pipe lining solutions.
