The SmartRack 42U Standard-Depth Rack Enclosure Cabinet protects sensitive electronic equipment from harsh conditions that would overwhelm a typical rack enclosure, including falling dirt, dust, drips and splashes. It is ideal for use in factories, construction areas, utility plants, warehouses and other areas high in moisture, dust and debris. It can protect your equipment from falling dirt, dust, drips, splashes and accidental contact with personnel.

The front and rear doors have ventilating louvers instead of open mesh. They also have a sealing gasket around the door frames. On the front door there are built-in dust filters as well as fans. The filters are removable and they can be replaced with standard furnace filters - they're simple, inexpensive and effective. To compensate for the added air resistance of the filters, there are 12 large, high performance fans on the front door. The fans effectively create positive air pressure within the rack, mimicking the same type of environment one would find within a commercial clean room. Positive air pressure prevents dust from penetrating even the smallest cracks of the enclosure. The roof of the enclosure is sealed with a cap that keeps drips and falling dirt from getting inside the enclosure. Since the doors and top are sealed, cable access is provided through 6 cable ports - 2 in the roof, 2 below the rear door, and 2 in the unit floor. They allow cables to pass through, but they block the area around the cables maintaining  protection.

The enclosure may be subjected to extreme vibrations and movements produced by vehicles and machinery. The heavy-duty steel frame supports up to 3500 lbs (1588 kgs). The large-diameter industrial casters also support up to 3000 lbs (1360.8 kgs), which means you can move the enclosure fully loaded. This is useful where you can install all your equipment in a clean environment, close the enclosure and wheel it to the dirty environment with all your equipment already protected.

After the enclosure is in place, the levelers allow you to compensate for minor floor variations and make sure everything is stable. If you need to build a data center in the middle of your factory floor, you can do it with this enclosure. It's perfect for locations like factories, power stations, construction areas, shipping facilities, warehouses, processing plants, transport hubs and anywhere you need to protect equipment in a harsh working environment.
