DESCRIPTION OF UNIT
The water cooled self-contained air conditioner is the
ultimate solution addressing the energy efficiency, reli-
ability, indoor air quality, and sound concerns for com-
mercial, industrial and institutional buildings. Johnson
Controls offers a simple system design, increases sys-
tem redundancy by providing individual air condition-
ing 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 chill-
ers, air handlers and rooftop systems and is now the
system of choice.
