Portable Clean-Air Close-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 an ionizer/air filter to improve air quality. It is designed to cool small offices, laboratories and breakrooms without access to facility air conditioning. It can also be used to spot-cool overheated rack enclosures and micro data centers or hot spots inside or outside an enclosure.

12,000 BTU of Cooling Power Protects Against Hazardous High Heat
This cooling unit pumps 12,000 BTU (3.5kW) of cooling into a small room or closet. It uses environmentally friendly R410A refrigerant to comply with worldwide standards. An easy-to-read control panel with diagnostic LEDs provides convenient local management.

Rack/Spot AC Unit Focuses Cold Air Where It’s Most Needed
Close-coupled air conditioning delivers cold air near heat loads to discourage recirculation and increase energy efficiency. An included flexible hose expands to 71 inches to help you aim the cold air to a specific spot, such as an overheated rack enclosure or equipment hot spot. Hot air exits through a window or drop ceiling via an included exhaust kit. An upgraded hot air exhaust fan maintains effectiveness even under a high heat load. The unit also dehumidifies, filters and ionizes the air, providing better air quality that can enhance operating conditions.

Commercial-Grade Components for Reliable Performance
With a 100-percent duty cycle, the SRCOOL12KWT can run continuously without costly downtime. It uses copper tubing that is stronger than the aluminum tubing used in most consumer cooling units. The copper allows higher pressures and better weld joints to stand up to the constant vibration of the running compressor.

Built-In Evaporator Ensures No Water Collection Tank to Empty
The evaporator expels the condensed water through the directional exhaust duct, eliminating the need for a drain tube, drain pan or water collection tank and saving you time and money. No external condenser, refrigerant piping or professional maintenance is required for simple operation. A microprocessor controls the compressor to cycle on and off, while the evaporator fan stays on to prevent icing in high humidity.

Optional Remote Management Accessory for 24/7 Monitoring and Control
Install the optional SRCOOLNET2LX network module (sold separately) to monitor temperatures, receive alerts, review logs and control settings from anywhere, anytime, via SNMP, web browser, SSH, telnet or command line interface. The built-in LX Platform’s PowerAlert® Device Manager provides a single interface to cycle the connected air conditioner on and off, adjust its fan speed, change its target set point temperature and switch to dehumidification mode.

Designed for Simple Plug-and-Play Installation by Almost Anyone
The self-contained SRCOOL12KWT requires no disruptive installation projects or costly service calls from HVAC specialists. It rolls on four casters into a compact 12 x 20 inch area. The six-foot power cord’s NEMA 5-15P plug with leakage current protection connects to a standard AC outlet. The unit is programmed to restart automatically after power failures, and a built-in timer allows unattended shutdown and startup.
