Russell makes commercial refrigeration equipment used on walk-ins, including unit coolers and condensing units. Typical repairs are fan motors, defrost heaters and controls, coil cleaning, electrical parts and refrigerant leaks. Photograph the Russell nameplate and call with what the walk-in is doing.
Russell refrigeration equipment cools walk-ins in food service and institutional kitchens. In many boxes, a Russell unit cooler hangs from the ceiling while the condensing unit sits outside.
About Russell equipment
Russell produces commercial refrigeration products such as unit coolers and condensing units for walk-in coolers and freezers. The unit cooler holds the evaporator coil, fans and defrost parts. The condensing unit holds the compressor and condenser. Each has its own nameplate with model, serial and electrical details.

Watch the unit cooler
Many Russell problems show up first at the unit cooler inside the box: a fan that stops, ice that builds on one side or water that drips from the pan. A quick weekly look at the coil and fans catches these early. See the evaporator coil and defrost heaters.
Before you call
- Photograph the nameplate on the condensing unit or unit cooler.
- Note the refrigerant listed on the nameplate.
- Note whether it is a cooler or freezer system and the defrost type if known.
- Describe what it is doing: temperature, fans, ice, noise or tripping.
- Note the box brand if there is a label on the door frame.
Do not open electrical panels, touch capacitors or loosen refrigerant fittings. The troubleshooting guide lists safe checks, and the brands guide shows where to find every nameplate.
What we look at on a Russell system
Many Russell problems show up first at the unit cooler, so that is where we start: fan motors and guards, coil frost pattern, defrost heaters, the termination switch and the drain pan and heater. We then check the expansion valve and the condensing unit outside, including the coil, fan and electrical parts. Water dripping from a Russell unit cooler is almost always a drain or defrost issue, and we trace it back to the cause.
Repair, upgrade or replace
Unit coolers can often be repaired part by part. If a coil leaks or corrodes, replacing the unit cooler may be the better choice, matched to the existing condensing unit. See the repair or replace guide and upgrades and retrofits.
