AERO Systems
Engineering has
designed a unique
PCA system for
the new Salt Lake
City Airport.
THE SALT Lake City International Airport (SLC)
opened its new terminal complex in 2020,
modernizing their 60-year-old facilities to meet the
increased passenger demands of the present, said
Bill Wyatt, executive director of the Salt Lake City
Department of Airports.
" Salt Lake City International
Airport served more than 27 million
passengers in 2019, in facilities that
were constructed 60 years ago to
handle 10 million passengers per year.
As a hub operation with numerous
f lights arriving and departing around
the same time, the previous design was
no longer efficient. In addition, security
needs are vastly different from when
the airport was originally constructed,
and buildings no longer met earthquake
safety standards, " explained Wyatt,

adding that the entire project costed $4.1
billion, with " no local taxpayer dollars
spent on the construction. "
A major part of the modernization
project was the introduction of a new
innovative Central Preconditioned
Air (PCA) system design by AERO
Systems Engineering (ASE). PCA
systems provide air conditioning to
parked aircraft during ground support
operations.
" This is one of the most substantial
and cutting-edge central plant designs

in the United States in the last decade, "
said Vern Landrum, senior mechanical
engineer at ASE.
Most PCA central plants are twopipe systems, where there is a single plant
that provides heating and cooling with
a single set of supply and return piping.
The SLC design is a four-pipe central
PCA plant utilizing separate heating and
cooling systems, each with their own set
of supply and return piping. This fourpipe design allows for an immediate
transition between the cooling and
heating operation at the concourse gate
PCA unit, without the transition delay
inherent to a two-pipe system, where
the entire fluid volume in the system has
to be heated or cooled by 120-degrees
resulting in lost time and wasted energy.
" Salt Lake Cit y's weather is
prone to large temperature swings
