Carrier Gemini 38AU/40RU Split System

Constructed for Long Life

The 38AUZ single circuit and 38AUD dual circuit, scroll compressor models are designed and built to last. The outdoor coil construction allows for a more efficient design in a smaller cabinet size providing a reduction in refrigerant charge. Where conditions require, a special coil coating protection option is available. Cabinets are constructed of pre-painted 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 AlertTM diagnostic and troubleshooting control system. This protects the units operation and provides valuable diagnostic information when required.

Efficient Operation

Gemini air-cooled condensing units provide EERs up to 11.5 and IEERs up to 13.2, which meet the ASHRAE 90.1 efficiency levels. This high efficiency helps reduce overall operating cost and energy consumption.

Dependable Performance

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 or loss of charge 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.

Carrier CENTURION Premium Packaged Rooftops


As the recognized leader in providing constant volume packaged equipment to the Heating, Ventilation and Air Conditioning (HVAC) market, Carrier once again demonstrates its leadership by providing a rooftop unit with ultra high efficiencies, combined with easy service and high reliability that utilizes Puron® refrigerant. And since Puron refrigerant is not affected by the 2010 Hydrochlorofluorocarbons (HCFC) ban, you can rest assured that the operating and maintenance cost savings provided by these CenturionTM Premium Packaged Rooftop units, available from 2 to 25 tons and in 13 sizes, will last.

Centurion rooftop units are now available with the EnergyXTM system which precon-ditions the rooftop’s intake air allowing higher operating efficiencies and increased comfort control while reducing the cooling and heating capacity requirements of the Centurion. Also available, the Humidi-iZer Adaptive Dehumidifi-cation system provides the Centurion an even greater degree of operational flexibility and enhances humidity control for consistently maintaining year round indoor comfort temperature and humidity levels.

The Right Level of Control

Centurion rooftop units may operate as part of a communicating network or as a stand-alone unit. Units are available with electromechanical controls or with Carrier’s ComfortLinkTM Direct Digital Controller (DDC). Units may be connected to the 3VTM Packaged Control System to maximize comfort and utility costs or to a simple thermostat for space temperature control.

The 3V Packaged Control System is Carrier’s commercial control system designed to maximize occupant comfort and minimize utility costs. It allows building devices to be accessed remotely or on-site, and ensures that building climate and energy control are operating according to specifications.

3V system components include factory- mounted unit controllers (like Carrier’s ComfortLink control system), space temperature sensors, system interface devices, and preprogrammed light commercial building controllers that can be used in any combination to control building heating, ventilation, air conditioning equipment, lighting and many other ancillary devices.

For stand-alone units, Carrier’s ComfortLink control system makes it easy to monitor and control each Centurion rooftop. A large scrolling marquee acts as a window into the unit’s operation, providing easy-to-read information such as unit pressures, temperatures and a host of read/write functions, which allow the user to configure the unit for precise operation. This intuitive interface greatly reduces start-up and operator training time.

Carrier WeatherMaker Commercial

Easy to Install, Operate and Service

Designed with streamlined installation in mind, Carrier® WeatherMaker® rooftops have everything you need from handled access doors to certified and pre-engineered factory installed options and field installed accessories. Most Carrier rooftops are also designed with the same roof curb footprint to fit on older models dating back over 20 years.

Factory and field stocked, WeatherMaker units are available in gas heating/electric cooling, electric heat/electric cooling or packaged heat pumps and deliver SEERs as high as 13.4 and EERs up to 11.3. WeatherMaker rooftops have the capability for vertical or horizontal air flow for fast and easy installation. High-efficiency gas heating (up to 82% efficiency) with induced draft design facilitates long life and safe operation. Carrier WeatherMaker rooftops can satisfy nearly any light commercial application need.

Turn to the Experts

Truly a leader in innovation, Carrier was the first company to utilize environmentally sound Puron® refrigerant in HVAC units. Without depleting the ozone layer, Puron refrigerant delivers ideal indoor air quality. Today over 2.5 million homes and businesses operate on Puron refrigerant-based HVAC systems. And as emphasis on environmental sensitivity continues to increase, Puron refrigerant will only become more relevant. Puron refrigerant is the refrigerant of the future.
