38AH Commercial Air-Cooled Condensing Unit Features
Carrier's 38AH air-cooled condensing units are available in nominal 20, 25 and 30-ton sizes. Designed to match with Carrier's 40RM or 39 series air handlers. Utilizing Carrier's time-proven, highly reliable 06D and 06E reciprocating semi-hermetic compressors, these units include dual independent refrigerant circuits and cylinder unloading capability for design and application flexibility for either constant volume or variable volume (VAV) systems. Each compressor has vibration isolators to provide quiet operation and reduced component stress. Because 38AH units have 2 independent circuits, they provide inherent backup capability.
Efficient 38AH Series units save energy, providing condensing unit EERs up to 11.6. The 38AH condensing unit offers the utmost in system configuration and control adaptability. Its premium-quality standard components ensure durable, efficient operation. All condensing unit circuits can supply a single air handler or 2 separate air handlers. Standard units have constant volume control. A variable air volume (VAV) option is available. VAV units have electric unloaders on the compressors to closely match building loads. The VAV option requires only a simple connection to the Carrier ModuPanel&tm; discharge air controller, thereby saving installation time and cost.
All 38AH units have weatherized cabinets constructed of heavy-duty galvanized steel pre-painted with corrosion-resistant baked enamel. Inside and outside surfaces are protected to en-sure long life and good looks. The units exceed the requirements of the Federal Test Method Standard No. 141 (Method 6061) 500-hour salt spray test. The unit's coils have aluminum fins mechanically bonded to copper tubes for long-term reliability and improved heat transfer. Copper fins on copper tubes are available for harsh industrial or coastal conditions.
