Rosenberg UNOBOX Fans Are Now Available In Standard AC Models For Equipment Cooling and HVAC Applications

Charlotte, NC (PRWEB) October 03, 2013 -- Rosenberg, a major manufacturer of high-quality fans and blowers, recently introduced its new electronically commutated UNOBOX fans for data center cooling retrofits. The company has now expanded the UNOBOX line to include standard AC models for use in harsh environments or where variable frequency drives are already employed.

The Rosenberg UNOBOX extract fan consists of a backward-curved motorized impeller mounted inside a cube-shaped cabinet with an aluminum frame and double skinned side panels. Integral inlet cones are optimized to achieve the best possible airflow and lower the noise level. Side panels are removable so that discharge is possible in different directions.

Available in seven fan sizes, 355-mm through 710-mm, and four cabinet sizes, 500-mm through 1020-mm, AC UNOBOXES are designed to handle air volumes from 1,800 CFM up to 10,800 CFM (depending on the actual system static pressure), ideal for many equipment cooling and HVAC applications. Rosenberg external rotor AC motors have IP54 rating protection.

Eliminating old-fashioned belt-driven blowers, the UNOBOX can be used singly or installed in multiples to fit space and air movement requirements. The UNOBOX's double-skinned (20mm) galvanized steel side panels are insulated with non-flammable, noise and temperature insulating fiberglass mats. Condensation is almost non-existent.

UNOBOX fans are also available with EC motors. In comparison to conventional AC driven fans, Rosenberg’s ERP-ready EC fans are more easily speed controllable and operate at much higher efficiency levels.

In addition to the standard UNOBOX line, Rosenberg’s flexible production and application engineering capabilities make it possible to manufacture fans for specific applications and unique customer requirements.
