30RB AQUASNAP®-1

AQUASNAP® 30RB060-390 Air-Cooled Chillers Product Data The AquaSnap chiller is an effective allin-one package that is easy to install and easy to own. AquaSnap chillers cost less to purchase and install, and then operate quietly and efficiently. Value-added features include: • Rotary scroll compression • Puron® HFC refrigerant (R-410A) • Quiet AeroAcoustic™ fan system • Easy to use ComfortLink controls • Optional full heat reclaim package • Optional integrated hydronic pump package, available with variable frequency drive (VFD) • Novation® heat exchanger technology with microchannel coil Features/Benefits Carrier’s superior chiller design provides savings at initial purchase, at installation, and for years afterward. Costs less right from the start Carrier’s AquaSnap chillers feature a compact, all-in-one package design that installs quickly and easily on the ground or the rooftop. The optional pump and hydronic components are already built in; this costs less than buying and installing the components individually. The chiller’s fully integrated and pre-assembled hydronic system installs in minutes. No other chiller in this class installs so easily and inexpensively. The preassembled and integrated hydronic module (available with VFD) utilizes top-quality components and pumps to ensure years of reliable operation. The AquaSnap unit’s high efficiency keeps operating costs down. * Meets IBC 2006, ASCE-7-05, CBC 2007, and OSHPD seismic requirements. Copyright 2012 Carrier Corporation

Features/Benefits (cont) AquaSnap® chillers make noise in the marketplace, not the workplace The AquaSnap chiller’s AeroAcoustic™ fan is almost twice as quiet as the competition’s per cfm. Much of the noise reduction is in frequencies where noise is most annoying, which makes AquaSnap chillers ideal for soundsensitive environments. When lower ambient temperatures allow part load operation or during scheduled nighttime operation, the units operate with fewer fans and become even quieter. AquaSnap chillers are quiet during the day and even quieter at night. The savings will continue to mount Besides...

Due to the compact all aluminum design, microchannel coils will reduce overall unit operating weight by 6 to 7%. The streamlined MCHX coil design reduces refrigerant charge by up to 30%. The coil is designed with rubber isolation around the powder painted coil frame to eliminate galvanic couples which can cause corrosion due to dissimilar metals. Optional integrated heat reclaim package For applications with a simultaneous requirement for chilled water and tempered heat water, the heat reclaim option is an ideal solution.
