The SRCOOL18K SmartRack 18,000 BTU 208V/240V Portable Air Conditioning Unit pumps 18,000 BTU of cooling power into your IT environment to prevent shutdowns, malfunctions and failures caused by overheating or fluctuating temperatures. Part of the SRCOOL line, this compact, portable unit is perfect for server rooms and other IT environments with heat-sensitive equipment in areas that facility air conditioning can't reach.

The self-contained SRCOOL18K is capable of cooling a small room up to 850 square feet using its louvered vent. A built-in evaporator expels the condensed water through the directional exhaust duct, eliminating the need for a drain tube, drain pan or water collection tank.

You can also use the included flexible tube to aim the cold air precisely where it's needed most, such as an overheated rack enclosure or an equipment hot spot. The SRCOOL18K also dehumidifies and filters the air, providing better air quality that can enhance equipment performance with little power consumption.

Designed for quick, simple installation, the SRCOOL18K rolls into place on durable built-in casters and plugs into a standard 208/240V 20A outlet. It's programmed to restart automatically after power failures, and you can set the built-in timer for unattended shutdown and startup.

By installing the optional SRCOOLNET remote management accessory (sold separately), you can also monitor temperatures, receive alerts, review logs and control settings from anywhere via SNMP, web browser, SSH or telnet.
