2 MEDIUM PROFILE UNIT COOLER
FEATURES
Our Medium Profile Unit Coolers are the perfect evaporator solution for medium to large walk-in coolers and freezers. Designed with efficiency, performance and service in mind, the Medium Profile line truly stands out from the competition. The unit coolers were engineered to meet the Department of Energy's new AWEF* performance regulations and all feature energy-efficient rail-mount Dual Speed EC Motors. For maximum performance, all units are circuited for multiple refrigerants and feature optimized circuit patterns, enhanced surface coil tubing, and new high efficiency fan and venturi designs. The Medium Profile product line has several serviceability features including rail-mount motors, easily removable fan guards and modular fan panels, face mount defrost heaters, hinged drain pans, and shipping pallets designed to facilitate quicker installation.
SIZES
There are a wide array of sizes available with capacities ranging from 11,000 to 99,000 BTUH at a 10° TD. Models are available with air flow spanning a range of 2,090 to 9,580 CFM.
HOUSING
Each unit is constructed with a rust-free, heavy gauge, textured, aluminum housing which is light weight yet extremely durable. Models feature hinged one-piece drain pans to allow for convenient servicing and maintenance. Hanger holes are provided on all units for fast installation.
COIL
Seamless copper tubes are staggered and mechanically expanded into corrugated aluminum fins to assure maximum heat transfer. Die formed fin collars are provided for accurate fin spacing. Top panel is fastened directly to the tube sheets of the coil to provide high structural strength. Low Temp Electric Defrost and Hot Gas Defrost Models are available in both 6 FPI and 4 FPI. Medium Temp Electric Defrost and Air Defrost models are available in 6 FPI.
MOTORS
All models feature highly efficient Dual Speed Electronically Commutated (EC) motors which are compliant with California Title 24 regulations.
FANS & FAN GUARDS
Powerful heavy-duty aluminum fans are individually balanced to provide vibration free operation. Standard heavy-gauge wire fan guards are UL/cUL-approved epoxy coated for corrosion resistance. Air throw for Medium Profile Unit Coolers is 75 ft.
REFRIGERANTS
Medium Profile Unit Coolers are optimized for multiple refrigerants including R404A, R407A, R448A, R449A and R744 DX (CO2). Please specify system refrigerant requirements when ordering. A separate compartment is provided for all refrigerant connections which allows ample room for internal mounting of expansion valves.
AIR DEFROST
Air Defrost models are designed for use in coolers at +35°F room temperature and warmer.
MEDIUM PROFILE UNIT COOLER 3
ELECTRIC DEFROST - MEDIUM TEMP
Medium Temperature Electric Defrost Models are designed for use in coolers between 10°F and 35°F room temperatures. Defrost heaters are mounted on the air intake side of the unit for optimal performance and easy maintenance. Heaters are installed inside the drain pan for fast, reliable drainage. Adjustable defrost termination, fan delay and heater safety controls are factory mounted for optimum performance of each control function.
ELECTRIC DEFROST - LOW TEMP
Low Temperature Electric Defrost Models are designed for use in freezers between +10°F and -30°F room temperatures. Defrost heaters are mounted on the air intake side of the unit for optimal performance and easy maintenance. Heaters are installed inside the drain pan for fast, reliable drainage. Adjustable defrost termination, fan delay and heater safety controls are factory mounted for optimum performance of each control function.
HOT GAS DEFROST
There are two types of Hot Gas Defrost models available: 3-pipe Hot Gas models and 2-pipe Hot Gas Reverse Cycle units. Hot Gas Defrost models are designed for use in coolers and freezers between +35°F and -30°F. Hot Gas Defrost 4 FPI models are designed for use in freezers between +32°F and -30°F. All units include adjustable defrost termination and fan delay controls which are factory mounted for optimum performance of each control function. Hot Gas Defrost models feature electric drain pan heaters making it possible to open the hinged drain pan for easy cleaning and servicing. Refer to the current Technical Bulletin for piping.
ELECTRICAL
Available in 115/12 (Air Defrost only) 208230V/12, 208-230V/32, 460V/1, or 460V/32. A large compartment is supplied for all electrical components and is easily accessible by removing the end panel. All models are UL and cUL listed.

4 MEDIUM PROFILE UNIT COOLER
ECONET ENABLED UNIT COOLERS (OPTIONAL)
Developed in conjunction with Rheem Manufacturing specifically for walk-in coolers and freezers -- it builds on the reliability and efficiency of Rheem's EcoNet technology
· Saves energy in refrigeration systems through precise superheat and space temperature control, fan cycling, and controlling how often the system goes into defrost based on compressor runtime
· Eliminates unnecessary defrosts · Maximizes energy efficiency with less compressor runtime · Reduces fan speed to 50% during off cycle for energy savings · Can be used with a condensing unit in single and multiple evaporator
installations as a group Optional EcoNet Command Center with intuitive graphical interface controls up to 32 devices (including the Command Center) through one display, continuous communication between system components, and remote mount display allows for EcoNet Enabled Unit Coolers to be programmed, monitored and troubleshot outside of space being cooled.

HOT GAS 3-PIPE MODEL
The system uses 3 pipes -- 1 for liquid line, 1 for suction line and 1 for hot gas. The hot gas is taken from the discharge line, between the compressor and the condenser, through a hot-gas solenoid valve to the distributor tee then through the coil.

EVAPORATOR APPLICATION RATINGS
Multiple conditions combine to determine the application capacity of an evaporator. Walk-in space temperature, relative humidity, saturated suction temperature difference, and outdoor ambient temperature. All of the factors are considered when calculating an evaporator application rating. These ratings are considerably higher than the net capacity value used for DOE ratings (AWEF).
The AWEF of an evaporator is calculated using the dry coil capacity and the daily evaporator power consumption. Power consumption included fan and defrost power. Evaporator net capacity reported to the DOE database is dry coil capacity less the full power fan watts. DOE test conditions are at 10°F evaporator/SST temperature difference and less than 50% relative humidity and 96°F liquid temperature. These conditions create a uniform test method, but should not be used for equipment selection. The equipment selected would be too large for the application.
Published application ratings are a guideline for proper equipment selection. They account for true operating conditions experienced by equipment.
