Rack-Mount Cabinet

The award winning AcoustiRACK™ ACTIVE (ARA™) is a soundproof, rack-mount cabinet providing unprecedented levels of noise reduction – up to 30 dB(A) with 8 KW of heat dissipation and dust protection for 19-inch servers and networking equipment. When combined with unique, high-quality acoustic materials, the ARA™ achieves previously unattainable spatial noise reduction over the entire frequency bandwidth of the audible spectrum.

Extreme energy consumption is the number one challenge facing data centers today. Using the ARA™, companies are freed from paying exorbitant energy bills to hypercool dedicated server rooms just to avoid equipment burnout. Employees are no longer faced with the myriad of physical and psychological ills associated with exposure to chronic noise pollution.
The ARA™ is offered in 15U and 33U.
