Features and Benets

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.

NSF listing applies

New EC Motors for PRO3 Top Mount Packaged Refrigeration Systems

Introducing the most energy ecient motor available for packaged refrigeration systems. Choosing energy
ecient motors for your packaged systems can provide signicant 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 eciency and equipment reliability.
EC motors by InterLink™ are up to 75% ecient – 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 signicantly lower your energy costs. PSC motors average 30-35%
higher eciency than shaded pole motors and oer dual energy savings by reducing motor watts and heat gain
into the refrigerated space.
