Features and Benefits
The PRO3 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 PRO3 family, the PRO3 Side Mount is optimized for outdoor applications and is ideal for
small- to medium-sized restaurant and convenience store applications where maximum airow is essential for
pulling down the temperature of foods or beverages. The Side Mount PRO3 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 PRO3 Top Mount packaged refrigeration system (models
PTN and PTT).
Ease of Installation and Service
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
•
Ease of Use
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

•
Refrigeration Parts:
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 PRO3 Side Mount packaged refrigeration system uses approximately
•
10 percent* of refrigerant required for a comparable split system
* Results may vary. Estimate based on a typical 100-foot refrigerant line length.
