Dealer Design Awards

Gold-winning Rheem Mfg. Co. spent three years researching and developing its next-generation EcoNet® Smart Thermostat, which builds off the company’s extensive work in sensor technology that began in 2012. “Unique to the category, it is the only thermostat smart enough to optimize the performance of a home’s HVAC and water heating appliances,” said Carson Burrus, controls product manager at Rheem.


Russell Low Profile Unit Cooler


The Russell All-Temps are the original low-profile unit coolers that established the industry standard as the all-purpose design for walk-in coolers, freezers, and other applications. The units feature an air drawthrough design, easy access for serviceability, and are available in air, electric, and hot gas defrost models.

SIZES: A wide array of sizes are available with capacities ranging from 3,600 to 39,000 BTUH at a 10° TD spanning from 740 to 4,980 cfm. One through six fan models are available.

HOUSING: The embossed Aluminum casing is lightweight yet durable. Each fan section is baffled to prevent short cycling of the air. The unit is designed to be mounted flush to the ceiling and meets all NSF requirements. The top pan is slotted for simple installation. Drain fittings are installed in the bottom of the drain pan for easy field connection, and the drain fitting can be quickly replaced without replacing the entire drain pan. The end panels can now be slid out from the front of the unit for easy serviceability from the front or end of the unit.

COIL: Copper hairpins are staggered and mechanically expanded into corrugated Aluminum fins and tube sheets to achieve maximum heat transfer. Die-formed fin collars provide even fin spacing and are available in 4, 6, and 8 fins per inch. Sweat connections are standard on all models.

MOTORS: High-efficiency single-speed and dual-speed Electronically Commutated (EC) motors are available in 115V and 208/230V. The dual-speed EC motors are compliant with California Title 24 regulations. Single-speed PSC motors are available in 115V, 208/230V and 460V. All motors include thermal overload protection.


Units are available as Configurable (no mounted accessories) or Pre-assembled with the most requested options installed for your convenience.


  • Blank = Configurable
  • T = Factory mounted TXV
  • L = Factory mounted TXV, Liq. Line Solenoid (LLS) and Mechanical T-Stat
  • M = Master Configuration with mounted TXV, T-Stat, LLS, and copper Tee

FANS: Heavy-duty 12” Aluminum fans are balanced to provide vibration-free operation. Our low-throw black plastic fan guards provide an optimal air pattern. The optional epoxy resin high throw fan guard moves air up to 25 feet.


• Coated Aluminum fins (Russproof, ElectroFin2, or Heresite2) or Copper fins
• Coated housing (same options as above)
• Epoxy resin high throw guards for up to 25 ft.
• Adjustable termination/ fan delay control*
• Insulated drain pan*

ELECTRICAL: Available in 115V, 208/230V and 460V. All components are factory-wired to convenient screw-type terminal strips. A large compartment is supplied internally to the unit for all electrical components and is easily accessible by opening the slide-out end panel. All models are listed UL and cUL and available in 60 or 50 Hz.

AIR DEFROST: Air Defrost models (prefix “AA”) are designed for use in coolers of 35°F and warmer. Complete air defrost systems for off-cycle or timed air defrost are available.

ELECTRIC DEFROST: Electric Defrost models (prefix “AE”) are designed for use in coolers and freezers between 34°F and -20°F. Internal coil heaters provide rapid and efficient defrost. A lower heater is installed close to the drain pan for fast, reliable drainage. When the temperature is satisfied, a defrost termination fan delay thermostat (DTFD) terminates the defrost cycle. The fan delay allows the warm coil to cool after a defrost cycle before the fans turn on. A heater safety thermostat is installed to prevent heaters from overheating above 75°F. Complete electric defrost refrigeration systems are available from Russell.

HOT GAS DEFROST: There are two types of Hot Gas Defrost models available: Hot Gas 3 Pipe (prefix “AH”) and Hot Gas Reverse Cycle 2 Pipe (prefix “AG”). Hot Gas Defrost models are designed for coolers and freezers between 30°F to -20°F. All models include a fixed DTFD factory wired and a hot gas drain pan circuit to defrost the drain pan. On all Hot Gas models, the drain fitting is located on the left-hand rear of the unit when facing the fan guards. Complete Hot gas defrost refrigeration systems are available from Russell.

* These options require the units to be built as Revision B models.
1. Codes T, L, and M are intended for units in finished goods inventory only. Call out separate options for units built with normal lead times.
2. ElectroFin and Heresite coatings are not NSF-approved. If ordered with these coatings, the NSF approval label will be removed from the unit.
