Carriers air-cooled split systems: provide a logical solution forcommercial needs

have a rugged, dependableconstruction

Features/BenefitsThese dependable splitsystems match Carriersindoor-air handlers and direct-expansion coils with outdoorcondensing units for a wideselection of commercialcooling solutions.

Up to 11.0 EERThe high efficiency split commercial splitsystem combining the 38ARZ/ARDoutdoor condensing unit with 40RM air

handling unit can save 20-27% of energyconsumption.

Constructed for long lifeThe 38ARZ (single circuit, scrollcompressor) and 38ARD (dual circuit,

scroll compressor) models are designed and

built to last. The copper tube-aluminum finoutdoor coil construction provides years oftrouble-free operation. Where conditions

require, a range of Enviro-Shield coilprotection options are available. Cabinets

are constructed of prepainted galvanizedsteel, delivering unparalleled protectionfrom the environment. Inside and outsidesurfaces are protected to ensure long life,good looks, and reliable operation. Safetycontrols are used for enhanced system

protection and reliability.

NOTES:1. 38ARZ unit is in accordance with ARI 270-95 Sound Rating of Unitary Equipment.2. Estimated sound power levels, dB re 1 Picowatt. 38ARD014-024 and 38AKS data is based upon a limited amount of actual testing with the estimated sound power

data being generated from this data in accordance with ARI Standard 370 for large outdoor refrigerating and air-conditioning equipment. Since this data is estimated, thesound power levels should not be guaranteed or certified as being the actual sound power levels.3. The acoustic center of the unit is located at the geometric center of the unit.
