Portable Closed-Coupled Cooling with Upgrades for Better Performance

 Based on the award-winning SmartRack® SRCOOL12K, the SRCOOL12KWT is a portable, compact, self-contained air conditioner with a silver ionizing air filter that improves air quality. It is ideal for cooling small offices, labs and breakrooms with no access to facility air conditioning. It can also be used to cool overheated rack enclosures, micro data centers and equipment hot spots, either inside or outside a rack enclosure.

12,000 BTU of clean, cold air

The SRCOOL12KWT pumps 12,000 BTU (3.5kW) of cold air into a small room, closet or rack enclosure. It uses environmentally friendly R410A refrigerant, which has been shown to provide better efficiency and performance than older refrigerants such as R-22.


  • Can cool a small room or closet with its louvered vent or focus cold air to a rack or hot spot through its flexible cooling duct.
  • A built-in air ionizer helps remove small particles such as dust and smoke from the air.
  • A silver coated filter with antibacterial properties further improves air quality.

Commercial-grade components for reliable performance

Certified compliant with the California Air Resources Board’s (CARB) Ozone and Electrical Safety standards, the SRCOOL12KWT is constructed of top-quality materials for long life and durability. With a 100-percent duty cycle, this small but mighty cooling unit can run continuously with no downtime.

  • Uses copper tubing, which is stronger and easier to repair than the aluminum tubing used in most consumer cooling units.
  • Copper tubing allows for higher pressures and stronger weld joints, ensuring the SRCOOL12KWT stands up to the constant vibration of the running compressor.
  • An upgraded hot air exhaust fan maintains effectiveness, even under a high heat load.

Optional remote management accessory

dd remote cooling management to your SRCOOL12KWT with an optional SRCOOLNET2LX module (sold separately), which allows full remote access for monitoring, event notifications and device management on your network.

  • Monitor temperature and humidity from any location 24/7.
  • Receive alerts, review logs and control settings via SNMP, Web browser, SSH, telnet or command line interface.
  • Built-in PowerAlert® Device Manager software provides a single interface to cycle the unit on and off, adjust fan speed, change target set point

Plug-and-play installation and user-friendly operation

The SRCOOL12KWT is designed for easy installation by almost anyone. Simply roll it into place on its built-in casters and plug it in. Its self-contained design requires no disruptive installation projects or costly service calls from HVAC specialists.

  • The 6 ft. power cord’s NEMA 5-15P plug with leakage protection connects to any standard AC outlet.
  • A built-in evaporator expels condensate through the unit’s directional exhaust duct, eliminating the need for a water collection tank and saving time and money on installation.
  • The unit is programmed to restart automatically after power failure, and a built-in timer allows unattended shutdown and startup.
  • Quiet Control mode regulates cooling via the unit’s timer and microprocessor to achieve quieter operation.
