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 efcient EC
(Electronically Commutated) motors, and can be paired
with the Heatcraft Beacon II™ Refrigeration System for
further energy efciency.
Benets & Advantages
Reduced Prole for Added Walk-In Storage
Unit Height of Less Than 11 Inches
• Lower unit height allows for improved storage space.
Reduced Drain Line Height
Straight Drain Line Design
• Minimal drain line height increases product storage.
• Reduced risk of drain line damage.
Ease of Service
Removable, Modular Fan Cassettes
• Allows for easy access to all components for cleaning.
• Serviceable outside of cooler in a warmer environment.
Removable Fan Guard
• Easily removed, attached with two screws.
• Made from durable polymer that is dishwasher safe.
Features
Application
• Air Defrost/Medium temperature walk-in cooler
Coil
• Refrigeration optimized small diameter coil pattern.
Air Mover
• Energy efcient EC motors standard.
• Curved centrifugal fan for optimal air ow.
Cabinet
• Hybrid design of metal and a high grade polymer.
Options
• Heatcraft Beacon II™ Refrigeration System
• Mounted Solenoid Valve
• Mounted Thermostatic Expansion Valve (TXV)
Mechanical and Electrical Access on Same Side
• Allows for easier unit service.
Energy Efciency & Substantiality
Energy Efcient Motors
• EC Motors come standard on all ULA models.
Optimized Coil for Reduced Refrigerant Charge
• Up to a 40% reduction in refrigerant charge.

10”
Low Prole
The industry standard for walk-in cooler applications.
Offering the broadest capacity range, from 4,000 to 37,000 BTUH, the
low prole 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.

The Most Servicable Unit Cooler Available
The Slim Contour units are a hybrid design, made from high strength polymer housings and metal, fans are modular and are easily removed to expose the coil and drain pan for easy cleaning.
Modular, removable air mover cassette
• Allows for easy access to components for cleaning.
• Modular cassettes allows for service in warmer environments.
Removable fan guards
• Fan guards are easily removed and easily cleaned.
• Made from durable polymer that is dishwasher safe.
Mechanical and electrical service access on same side
EA SY SE RVIC E ACCESS
• Allows for easier and faster service and installation with access to all critical
electrical and mechanical components on one side.
Exceptional Cooling Performance
The Slim Contour features a capacity range that mirrors that of the existing unit coolers in the Heatcraft unit cooler portfolio.
Only 1-3 Fan units shown. Center Mount Available in 1-5 Fans & Low Prole Available in 1-6 fan models.
