These dependable outdoor air cooled condensing units match Carrier’s indoor-air handlers to meet a wide selection of cooling solutions.

Carrier’s air-cooled air conditioning split systems:
  • Provide a logical solution for commercial needs
  • Have rugged, dependable construction
  • Available with single or dual refrigerant circuits.
  • Have cooling capability up to 125°F (52°C) ambient and down to 35°F (2°C) ambient standard
Constructed for long life
The 38AUZ single circuit and 38AUD dual circuit, air cooled condensing units are designed and built to last. The high efficient designed outdoor coil construction allows for a more efficient design in a smaller cabinet size that utilizes an overall reduction in refrigerant charge. Where conditions require, special coil coating coil protection option is available. Cabinets are constructed of prepainted galvanized steel, delivering unparalleled protection from the environment. Inside and outside surfaces are protected to ensure long life, good looks, and reliable operation. Safety controls are used for enhanced system protection and reliability. Each unit utilizes the Comfort Alert™ diagnostic and troubleshoot control system. This protects the units operation and provides valuable diagnostic information when required.
Factory-installed options (FIOPs)
Certified and pre-engineered factoryinstalled options (FIOPs) allow units to be installed in less time, thereby reducing installed cost.
FIOPs include:
  • Low ambient controls which provide cooling operation down to -20°F (-29°C) ambient temperatures
  • Non-fused disconnect
  • Special coil coating coil protection
  • Louvered hail guard
Efficient operation
These air cooled condensing units will provide EERs up to 12.0 (tested in accordance with AHRI standard 340/360). This high efficiency operation will help reduce overall operating cost and energy consumption.
Controls for performance dependability
The 38AU condensing units offer operating controls and components designed for performance dependability. The high efficiency hermetic scroll compressor is engineered for long life and durability. The compressors include vibration isolation for quiet operation. The high-pressure switch protects the entire refrigeration system from abnormally high operating pressures. A low-pressure switch protects the system from loss of charge. These units also include anti-short-cycling protection, which helps to protect the units against compressor failure.
All units include a crankcase heater to eliminate liquid slugging at start-up. Each unit comes standard with the Comfort Alert control system.
This provides:
  • System Go LED indicator
  • Fault LED indicator
  • Compressor fault LED indicator
  • Phase loss protection
  • Phase reversal protection
  • Safety pressure indicator
  • Anti-short cycle protection
Innovative Carrier 40RUA packaged air handlers are custom matched to 38AUZ/D condensing units.
Information on matching 40RUA DX packaged air handler follows for convenience. See separate product data for more details. The 40RUA Series has excellent fan performance, efficient direct-expansion (DX) coils, a unique combination of indoor-air quality features, and is easy to install. Its versatility and state-of-the-art features help to
ensure economical performance of the split system both now and in the future.
Indoor-air quality (IAQ) features
The unique combination of IAQ features in the 40RUA Series air handlers help to ensure that only clean, fresh, conditioned air is delivered to the occupied space.
Direct-expansion 4 row cooling coils prevent the build-up of humidity in the room, even during part-load conditions.
Standard 2-in. (51mm) disposable filters remove dust and airborne particles from the occupied space for cleaner air.
The pitched, non-corroding drain pan can be adjusted for a right-hand or lefthand connection to suit many applications and provide positive drainage and prevent standing condensate.
The accessory economizer can provide ventilation air to improve indoor air quality by using demand control ventilation. When used in conjunction with Carrier Comfort System and CO2 sensors, the economizer admits fresh outdoor air to replace stale, recirculated indoor air.
The 40RUA Series packaged air handlers provide reduced installation expense and energy-efficient performance.
Quick installation is ensured by the multipoise design. Units can be installed in either the horizontal or vertical configuration without modifications. Fan motors and contactors are pre-wired and thermostatic expansion valves (TXVs) are factory-installed on all 40RUA models.
High efficiency, precision-balanced fans minimize air turbulence, surging, and unbalanced operation, cutting operation expenses.
The economizer accessory precisely controls the blend of outdoor air and room air to achieve comfort levels. When the outside air enthalpy is suitable, outside air dampers can fully open to provide "free" cooling without energizing mechanical cooling.
Rugged dependability
The 40RUA series units are made to last. The die-formed galvanized steel panels ensure structural integrity under all operating conditions. Galvanized steel fan housings are securely mounted to a die-formed galvanized steel fan deck. Rugged pillow-block bearings (40RUA14) are securely fastened to the solid steel fan shaft with split collets and clamp locking devices. Smaller unit sizes have spider-type bearings.
Coil flexibility
Model 40RUA direct-expansion coils have galvanized steel casings; inlet and outlet connections are on the same end. The coils are designed for use with Puron (R-410A) refrigerant and have 3/8-in. diameter copper tubes mechanically bonded to aluminum sine-wave fins. The coils include matched, factory-installed thermostatic expansion valves (TXVs) with matching distributor nozzles and offer a removable power element and extended connections.
Easier installation and service
The multipoise design and component layout ensures quick unit installation and operation. Units can be converted from horizontal to vertical operation by simply repositioning the unit. Drain pan connections are duplicated on both sides of the unit. The filters, motor, drive, TXVs, and coil connections are all easily accessed by removing a single side panel.
