The PRO

3

 packaged refrigeration systems combine evaporator and condensing unit into one unit — simplifying 

installation and reducing refrigerant charge — saving time, money and energy. 
The latest addition to the PRO

3

 family, the PRO

3

 Side Mount is optimized for outdoor applications and is ideal for 

small- to medium-sized restaurant and convenience store applications where maximum airflow is essential for 

pulling down the temperature of foods or beverages. The Side Mount PRO

3

 is also available with electric defrost 

medium temperature models, ensuring maximum performance in storage applications slightly above freezing. 
For holding temperature with maximum space, see the PRO

 Top Mount packaged refrigeration system (models 

PTN and PTT).

Installation takes a fraction of the time required for a split system: refrigerant is pre-charged at factory, 

superheat adjustment is not required and unit slides into slots in standard walk-in panel (see installation manual 

for more information)
Designed for simple serviceability: the condensing unit section’s cabinet door can be quickly removed; in 

addition, the electrical box is located outside the cabinet for easy access
Flexible design allows for multiple installation methods: Optimized for outdoor use, but can be used indoors 

as well (with drain connection)
Lifting lugs and hanging brackets in evaporating section allow for easy installation

System is factory-assembled, evacuated, charged, run-tested and wired; no additional components required
Controls preset for typical applications: +38° F for high temp. coolers, +35° F for medium temp. coolers, -10° F for 

freezers and are easy to adjust

Maximized airflow: evaporator placement in walk-in box with pull-through fans 

 

Suitable for temperature pull-down and holding temperature 

Increased condenser capacity, by avoiding compressor heat 

Improved tolerance in high-ambient conditions

Electric defrost in medium temperature models, allowing for maximum 

performance in storage applications just above 32°F 
Fan-cycling for head pressure control
Crankcase heater
Drain line heater

System is fully-assembled and quality-tested at the factory
Electronic microprocessor control provides accurate temperature control
Liquid-line filter drier
Two-year parts warranty

PSC motors standard in both condensing unit and evaporator section
EC motors optional, but may be required in some states (evaporator section only)

Reduced refrigerant charge: the PRO
