ULA - Slim Contour Unit Cooler
Maximized Storage, Minimized Energy
The Slim Contour, an innovative unit cooler with
space-saving design offers enhanced servicability and
maximum cooling performance for the food service
industry.
The Slim Contour unit cooler is ideal for applications
where maximizing storage capacity in a walk-in cooler
is critical. At less than 11 inches in height, this unit
cooler has a 30% reduction in unit height compared to
traditional unit coolers in the market today.
The unit comes standard with energy efcient EC
(Electronically Commutated) motors, and can be paired
with the Heatcraft Beacon II™ Refrigeration System for
further energy efciency.
Benets & Advantages

10”
Low Prole
The industry standard for walk-in
cooler applications.
Offering the broadest capacity range,
from 4,000 to 37,000 BTUH, the
low prole unit cooler is designed
for maximum air ow and cooling
capacity inside a walk-in cooler.
More Space Where You Need It Most
Slim Contour Center Mount
Optimized for air defrost (medium
temperature) applications, the Slim
Contour unit cooler is ideally suited
for installations where storage space
is critical and a higher pull down
capability is desired.
Available in air or electric defrost,
ideal for tight storage situations
because they are ceiling mount and
have a height of less than 9” allowing
for maximum headroom in a cooler.
The center mount design provides
a moderated, evenly distributed air
ow throughout the box.
Before
THE CHALLENGE
• Traditional unit coolers take up valuable space within a walk-in cooler.
The drain line also extends another 6” beneath the unit; making it prone
to damage and further reducing storage space.
• Servicing the unit is also a challenge as the coil and drain pan cannot
be easily accessed for cleaning.
THE SOLUTION
• The Slim Contour unit cooler is optimized for applications where space,
performance, and serviceability cannot be compromised.
• The low 11” height, coupled with modular, removable fan cassettes
and a low drain line height maximize storage space while improving
serviceability.
