The SRCOOL18K SmartRack 18,000 BTU 208/240V Portable Rack Air Conditioner cools, dehumidifies and filters the air in your server room, data center or other environment with heat-sensitive equipment. The compact, portable unit fits into just 4 square feet of floor space. It is designed for supplemental or backup cooling of IT equipment to prevent shutdowns, malfunctions and costly downtime caused by overheating or fluctuating temperatures.

The self-contained SRCOOL18K packs 18,000 BTU/h (5.275 kW) of cooling capacity into a rack-width chassis. A built-in evaporator expels condensation through a directional exhaust duct, eliminating the need for a floor drain or water collection tank. The SRCOOL18K also dehumidifies and filters the air, providing better air quality that can enhance equipment performance. Efficient close-coupled cooling reduces energy use and operating costs.

Installation is quick and easy and does not require disruptive construction or the costly expense of hiring a plumber or HVAC specialist. The SRCOOL18K rolls into place on durable built-in casters. The NEMA L6-20P plug connects to a standard 208/240V 20A outlet. The unit restarts automatically after power failures, and a built-in timer supports unattended shutdown and startup.

By installing the optional SRCOOLNET2LX network management card (sold separately), you can monitor temperatures, receive alerts, review logs, automate operation and control settings from anywhere via SNMP, web browser, SSH or telnet. The SRCOOLNET2LX includes the ENVIROSENSE remote sensor, which lets you monitor temperature and humidity up to 12 feet away from the SRCOOL18K.

Frequently Asked Questions

Yes. An exhaust removal tube is included and must be used to vent the hot air out of the room or closet through a window or ceiling duct work.
For your convenience, the unit uses washable filters. Replacement filters are not sold separately.
Here are some possible reasons for a lack of cool air: the air exhaust or intake is blocked, the temperature setting is too high, the fan speed setting is too low, or the air filters are dirty.
