Product GEMINI™38AKS028-044 Data 38AH024-034 With 40RM016-034 Commercial Air-Cooled Split Systems 50 Hz 63 to 127 kW (18 to 35.8 Nominal Tons) These dependable split systems match Carrier’s indoor-air handlers with outdoor condensing units for a wide selection of commercial cooling solutions. Features/Benefits Building owners will appreciate the high unit EERs (Energy Efficiency Ratios) offered by the 38AKS and 38AH units. These units provide greater efficiency than similar units in the marketplace, which translates into year-round operating savings. Latest safety standards for 38AKS and 38AH units are assured through UL and UL, 38AKS,38AH Canada approvals. Constructed for long life The 38AKS and 38AH units are designed and built to last. Cabinets are constructed of pre-painted galvanized steel, delivering unparalleled protection against the environment. Inside and outside surfaces are protected to ensure long life, good looks and reliable performance. The copper tube- aluminum fin outdoor coil construction provides long term reliability and improved heat transfer. Where conditions require them, copper fin coils are available. For corrosive or coastal environments an epoxy barrier is available to provide superior coil durability. Reliability The 38AKS and 38AH condensing units offer the building owner components and operating controls designed for performance dependability. These 40RM016-034 condensing units feature the time proven highly reliable 06D and 06E compressors.
