The EC motor is an Energy Solutions® option on new Chandler Low Flow evaporators. Available on all new equipment or as an easy-to-install, drop-in replacement aftermarket part from InterLink™ Commercial Refrigeration Parts. Because they’re a drop-in replacement for existing shaded pole and PSC motors, installation is quick and easy. It’s a high impact, quick payback solution for reducing costs and achieving green initiatives without replacing the entire system.
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 permanent-split capacitor (PSC) motors. With all of this added eciency, you can count
on more energy savings and lower operational costs while taking a step in the right direction toward conserving our planet’s resources.

Features & Benefits
Low Flow unit coolers are ideal for meat storage and preparation rooms, oral coolers, dough retarding and many other applications requiring low air velocities and low sound levels. With low velocity unit coolers, high humidities can be maintained to prevent product drying and weight loss. These units are ideal for any type of workroom where human comfort is important.
Cabinet
Rust-free, all-aluminum white case with louvered intake grille for attractive appearance
•
Statically and dynamically balanced fans are designed for quiet air movement
•
All factory installed electrical components are wired to a terminal board in the junction box making eld wiring
• quick and easy
Inlet connection allows for external mounting of TXV
•
Coil
Sweat-type cooling coil connections reduce the potential for leaks
•
Nickel-steel alloy heaters provide a positive defrost and have long life
•
Electric defrost coils have a hermetically sealed defrost termination thermostat that does not require adjustment. Hot gas
• defrost units come with an adjustable defrost termination thermostat
Cross-n cooling coils with corrugated aluminum ns spaced 6 FPI & 3/8" OD staggered copper tubes provide optimum
• heat transfer and reduce the amount of refrigerant required
Generous coil surface helps to maintain steady room temperature and minimize product shrinkage
•
Access port on the suction connection allows superheat to be easily and accurately set
•
Drain Pan
Hot gas models use inner drain pans with low-wattage electric heaters. This eliminates the braze joints and tubing
• associated with hot gas drain pan loops
All models use inner drain pans to reduce sweating
•
Motors
Motors are factory-wired to unit junction box for fast installation
•
Thermal overload protected motors are resiliently mounted inside the unit to assure minimum noise level
•
High eciency PSC motors are optional on sizes 070 through 170. PSC motors are standard on sizes 190 through 270
•
EC Motors (optional) available factory-installed or as a drop-in replacement through InterLink™ Commercial Refrigeration
• Parts in 115/1/60 and 208-230/1/60
Options
Units available with copper fins. Air defrost units also available with polyester coated fins or various coil coatings options•
