The SR42UBEIS Industrial SmartRack Enclosure is ideal for customers who need to protect valuable equipment in harsh working environments that would overwhelm a typical rack. The enclosure has a NEMA 12 protection rating, which is equivalent to IP54. That means 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 and a sealing gasket around the door frames. On the front door there are built-in dust filters that are removable and can be replaced with standard furnace filters. To compensate for the added air resistance of the filters, there are 12 large, high performance fans to the rear door. The roof of the enclosure is sealed with a cap that keeps drips and falling dirt from getting inside the enclosure. Cable access is provided through 6 self sealing cable ports - 4 in the roof and 2 below the rear door and allow cables to pass through but block the area around the cables maintaining the NEMA 12 protection. The cabinet has a Zone 4 seismic rating, meaning it can withstand extreme movement and vibration, equivalent to the stress of a major earthquake. Even if it is used in an area where earthquakes are rare, the Zone 4 seismic rating is useful in any industrial setting, such as extreme vibrations and movements produced by vehicles and machinery. The heavy-duty steel frame and large-diameter industrial casters support up to 3000 pounds. 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.
