Air-Cooled, Rack Mounted Air Conditioners for Enclosures

Kooltronic Rack Mount AC units are particularly suited for cooling applications where internal horizontal mounting is preferred over external panel, door or top mounting. Rack mount air conditioners are available in two model options. The RML model, with a cooling capacity of 5,000 BTU/H, offers a choice of up to five airflow patterns, allowing installation in any location within a data storage server rack. Using supplied baffle plates the RML AC unit can easily be configured for a variety of applications. The H9 and H10 air conditioning units cool to a capacity of 3,500 BTU/H and are typically mounted internally at the bottom of a an enclosure. All rack mounted air conditioners include EIA-notched flanges, attractive 19-inch wide stainless steel grilles, baffles plates for airflow modification, and knurled captive fasteners for easy removal. If preferred, side rails can be supplied.
