DESCRIPTION OF UNIT
Versecon, the indoor vertical self-contained air con-
ditioner is the ultimate solution addressing the energy
efficiency, reliability, indoor air quality, and sound
concerns for commercial, industrial and institutional
buildings. Versecon offers a simple system design,
increases system redundancy by providing individual
air conditioning systems per floor, lowers maintenance
costs, eases operation and maintenance and provides the
lowest life cycle cost available. Based on these features,
the self-contained unit has surpassed the traditional
chillers, air handlers and rooftop systems and is now
the system of choice.
Models YSWD/YSWU012 to YSWD/YSWU090 are
factory assembled, refrigerant charged and tested, wa-
ter-cooled packaged air conditioning units designed for
ducted applications.
Each unit contains multiple hermetic scroll compres-
sors, water cooled condensers, multi-circuit evaporator,
thermal expansion valves, interconnecting refrigerant
piping, plenum supply fan, belt drive, fan motor, pleated
filters and all necessary operating and required safety
controls to operate the unit.
All rigging, installation, power and control wiring ex-
ternal to the unit, and condenser water and condensate
piping are the responsibility of the installer.
