Product Overview

Engineering Guide

Space Saver

Self Contained Water-Cooled Air Conditioner

Or Use With Remote Air-Cooled Condenser I Condensing
Section

These units are small in size, but big on performance and

features. Designed specically for applications having
limited oor space and accessibility, the VertiCool Space

Saver allows installation of a high capacity air conditioning

system with minimal room modications.

The VertiCool Space Saver has been engineered for use in
free blow plenum applications or ducted applications� The

water-cooled Space Saver can be specied in four cabinet
sizes ranging from 2 up to 15 tons. System exibility goes
even further. The Space Saver can also be congured for

chilled water utilization� When necessary the unit can be
matched with a remote air-cooled condenser or condensing
section (indoor or outdoor)�

The VertiCool Space Saver units are ideal for new
construction as well as renovation and replacement� The
foot print is one of the smallest, if not the smallest, in
the industry ton for ton� The low height and narrow width
allow it to pass through standard door ways for those
replacement and renovation projects�

• Access is from the front of the unit for components�
Easier to install, maintain or service unit�

• Access to the blower motor, belts and pulleys is from
the front� Maintenance or belt replacement is easier and
faster�

• Scroll compressors standard� Better performance under a
variety of operating conditions�

• The control box can be accessed while the unit is
operational� Provides easier access during installation,
start-up and servicing�

• Electric heat is removable from the side� Means easier
access if required�

• Water service connections are ush with the side of the
cabinet� Makes for a neater cleaner appearance when

placed in ofces or retail spaces.

• Chilled water coil connections out either side of cabinet�

Installation exibility.

• Condensate line is internally trapped� No um-sightly

trap external to the unit, faster installation and reduced

installed cost�

• Condensate can be taken out either side. Flexibility for
the installation�

• Variety of lter options. Satises more of what your
customers may want�

Pricing starts with a basic unit and you add in only those

additional features you want or need for your specic

application!
