Features and Benets
The PRO3 Top Mount and Side Mount packaged refrigeration systems combine evaporator and condensing unit into
one unit expediting installation time and reducing refrigerant charge — saving time, money, and energy.
These systems are designed to maximize storage space inside walk-in coolers or freezers and are ideal for small- to
medium-sized restaurant and convenience store applications.
Systems are fully-assembled, evacuated, charged, run-tested and wired at the factory. No additional components
are required.

New EC Motors for PRO3 Top Mount Packaged Refrigeration Systems
Introducing the most energy ecient motor available for packaged refrigeration systems. Choosing energy
ecient motors for your packaged systems can provide signicant energy savings and lower operational costs.
Additionally, because these motors can help reduce heat load (and system run-time), they can improve the
reliability and longevity of refrigeration equipment.
Electronically Commutated (EC) motors even further improve energy eciency and equipment reliability.
EC motors by InterLink™ are up to 75% ecient – that’s a 51-59% increase over shaded pole motors and a 30-35%
increase over PSC motors. As with PSC motors, you save money both directly from a decrease in motor watts and
also from a reduction of heat gain into the refrigerated space.
Permanent Split Capacitor (PSC) motors can signicantly lower your energy costs. PSC motors average 30-35%
higher eciency than shaded pole motors and oer dual energy savings by reducing motor watts and heat gain
into the refrigerated space.
