Overview Direct-Drive Hideaway Unit (HHDB) Belt-Drive Hideaway Unit (HHBB) The Direct-drive hideaway unit is designed for installation in a fully concealed ceiling location. These units will deliver desired air flows against a wide range of external static pressures associated with varying duct layouts. Unit features include: Belt-drive units offer 5 unit sizes from 800 to 3000 nominal CFM. The Belt-drive hideaway unit is designed for installation in a fully concealed ceiling location. These units incorporate most of the money-saving installation features of smaller Direct-drive fan coils, and...

Advantages The Large Capacity Advantage Large Capacity fan coil units combine cooling, heating, humidity control and filtering functions in a single compact unit expanding limitations usually associated with fan coil applications. These features make Large Caps desirable by building owners, specifying engineers, and contractors alike. For contractors, Large Capacity fan coils offer a stock program for fast delivery and a number of factory- and fieldinstalled features, making installation fast and simple. By using Large Capacity Fan Coils, building owners have an economical option, with features...

Features Hideaway and Cabinet Direct-Drive Units (HHDB & HCDB) Hideaway type and cabinet type Large Capacity fan coil units are available for concealed installations or ceiling suspension within the conditioned space. Cooling, heating, dehumidifying and air filtering are combined in a single, compact unit. A full line of optional accessories makes these units completely versatile in application. Large Capacity fan coil units are designed to deliver the rated capacity against normal external static pressures, and may be installed for either “free” or “ducted” air delivery. Large diameter direct-drive...

Features Dependable Trouble-free Performance Standard Features Casing and Cabinet. Frame members and basic casing are constructed of G-60 galvanized steel. Cabinet unit casing is fabricated of G-60 galvanized steel with 1” thick neoprene coated fiberglass internal insulation.

Unit Selection The achievement of an efficient fan coil system is dependent upon accurate system design and proper equipment selection. Variations, limitations and control of fan coil systems, design conditions and design load calculations are not described in detail in this catalog. More detailed information may be found in the ASHRAE Guide, from which the design engineer can mike initial unit selections to meet the requirements of the system. The initial unit selection should be checked for air volume in the design system, and the cooling capacities checked at the actual operating conditions....
