Peace and quiet.
Why noise control? Increased productivity. Increased profits. Research shows that prolonged exposure to noise creates stress and lowers morale. It can also lead to an increase in accidents and errors. A simple 5 dB reduction in noise can actually cut the risk of hearing loss in half. A quiet office is a productive office. How many times have you gone into work early or on the weekend because you wanted peace and quiet?

The QuietCab reduces sound by an amazing 28.5 dB-the most you can get today in a soundproof enclosure. And, the cabinet goes through independent, third-party testing to ensure it. So what does that mean? Noise is measured in decibels. So 28.5 dB noise attenuation (or reduction) means that the cabinet is removing that amount of noise from the sound source.

The noise level in a busy office with people talking measures 78 dB. Normal conversation is about 60 dB. A quiet office with no talking is 48 dB. A whisper is 23 dB. If you put the cabinet in a busy office, you'll reduce the sound to that of an office without speech. If you start with a quiet office, the sound from the cabinet would be as quiet as a whisper. In other words, you won't hear the equipment unless you press your ear against the cabinet!

The cabinet design ensures noise reduction without compromising cooling capacity. To reduce sound, the inside of the cabinets are heavily lined with one of the most effective acoustic materials available. This heavy-duty, multi-layer composite material covers all inside surfaces. Even the three cable routing panels on top are covered. For ease of use, the panels are hinged and flip up like a door. Another cable routing panel at the base is also covered. Once you route cables, additional foam-insulation is provided to close any crevices.

Very cool.
Get the best thermal performance with an incredible thermal load capacity of up to 7.2 kW. That's the equivalent of 37 single-processor servers and peripherals. To cool equipment, the cabinet features two variable-speed fans on the rear doors that are controlled by a temperature sensor to ensure maximum energy efficiency. Cooling occurs as ambient air comes in the front of the cabinet and is exhausted out the rear.

Very accommodating.
This 19 cabinet is extremely well-designed and built to serve you for years to come. It holds all leading servers, including blade servers. To accommodate different types of equipment, the 19 M6 mounting rails are adjustable. It can hold a very hefty 1100 pounds of equipment. Load-bearing casters make it easy to move. Locking front and rear doors secure equipment. The cabinet is also designed with very generous cable-management for both horizontal and patch cables.
