AC and EC UNOBOX Fans Simplify Data Center Cooling
Featured Product from Rosenberg USA
As data center densities continue to increase, driving up energy usage, one of the most effective areas for data-center cost reduction is the updating and optimizing of the cooling fans. Rosenberg's UNOBOX fans, with electronically commutated (EC) or standard AC motors, are designed to make energy-saving data center cooling retrofits easier for both under-floor and in-cabinet applications.
The Rosenberg UNOBOX extract fan consists of a high-efficiency 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.
Rosenberg high-efficiency EC motors are easily speed controllable via integrated electronics. Air volume can be adjusted to any possible operating point. The integrated, intelligent electronics also allow for pressure or air quality control. Rosenberg’s standard AC models are often specified for use where variable frequency drives are already employed.
Available in seven fan sizes, 355 mm through 710 mm, and four cabinet sizes, 500 mm through 1020 mm, EC UNOBOXES are designed to handle air volumes from 1,500 CFM up to 11,500 CFM depending on the static pressure. AC UNOBOXES offer airlflow from 1,800 CFM up to 10,800 CFM.
Eliminating old-fashioned belt-driven blowers, the UNOBOX can be used singly or installed in multiples to fit the space and the air movement requirements of most data center applications. The UNOBOX's double-skinned (20mm) galvanized steel side panels are insulated with non-inflammable, noise and temperature insulating fiberglass mats. Condensation is almost non-existent.
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.
The Rosenberg family of companies is headquartered in Künzelsau, Germany and employs more than 1,400 individuals worldwide. Rosenberg fans and blowers can be found in HVAC systems, as well as industrial and portable air conditioning; in air cooling for variable frequency drives (VFD), wind power generators and power converters, solar inverters, uninterruptable power supplies (UPS), transformers, heat sinks, fan coils, telecom racks and other industrial equipment; in air handling units and fan filter units (FFU); and in railway, marine, military and avionics equipment.
