NAS introduces catalogue CRAHs for data centres

HVAC equipment manufacturer Nortek Air Solutions (NAS) has released ‘catalogue’ computer room air handlers (CRAHs) for data centres requiring option-configurable cooling units.

Ranging from 63 to 430 kW in nominal cooling power capacity, the new models allow consulting engineers to specify the user’s options. Featuring welded, heavy-duty structural steel tube cabinetry and dry powderbaked black or white finish, they are available with an optimized copper tube/aluminum fin A-frame coil or an optional high-capacity coil to achieve greater cooling within the same footprint. There are also two-, three- and four-fan options, plus downflow (for underfloor applications) or front-discharge configurations for supply air discharge.

The catalogue CRAHs supplement NAS’s legacy platform and mission-critical equipment lines, which continue to offer custom-built units to meet site-specific requirements.
