ULA - Slim Contour Unit Cooler

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 efficient EC (Electronically Commutated) motors, and can be paired with the Heatcraft Beacon II™ Refrigeration System for further energy efficiency.

Features

Application

• Air Defrost/Medium temperature walk-in cooler

Coil• Refrigeration optimized small diameter coil

pattern.Air Mover• Energy efficient EC motors standard.• Curved centrifugal fan for optimal air flow.

Cabinet• Hybrid design of metal and a high grade polymer.

Options• Heatcraft Beacon II™ Refrigeration System• Mounted Solenoid Valve• Mounted Thermostatic Expansion Valve (TXV)

Maximized Storage, Minimized Energy

Benefits & Advantages

Reduced Profile 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.Mechanical and Electrical Access on Same Side• Allows for easier unit service.

Energy Efficiency & SubstantialityEnergy Efficient Motors• EC Motors come standard on all ULA models.Optimized Coil for Reduced Refrigerant Charge• Up to a 40% reduction in refrigerant charge.

More Space Where You Need It Most

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.

Before After

Low Profile Slim Contour Center Mount

The industry standard for walk-in cooler applications.

Offering the broadest capacity range, from 4,000 to 37,000 BTUH, the low profile unit cooler is designed for maximum air flow and cooling capacity inside a walk-in cooler.

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 flow throughout the box.

The Most Servicable Unit Cooler AvailableThe 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.

Exceptional Cooling PerformanceThe 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 Profile Available in 1-6 fan models.

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

• Allows for easier and faster service and installation with access to all critical electrical and mechanical components on one side.
