Portable Close-Coupled Cooling with Customer-Inspired Upgrades for Better Performance
Tripp Lite’s award-winning SRCOOL12K, now in its second generation, is a portable, compact, self-contained air conditioning unit designed for server rooms, small network closets, back offices and other areas with heat-sensitive equipment that facility air conditioning can’t reach. Design improvements based on customer feedback include upgraded commercial-grade components designed to last longer, including an upgraded hot air exhaust fan. The SRCOOL12K Gen 2 also boasts robust packaging for better protection from shipping damage and an updated two-year warranty.

12,000 BTU of Cooling Power Protects Your Equipment Against Hazardous High Heat
This SmartRack® server rack cooling unit pumps 12,000 BTU (3.5kW) of cooling into your IT environment to help prevent shutdowns, malfunctions and other failures caused by overheating or fluctuating temperatures. 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 Cooling Focuses Cold Air Where It’s Most Needed
Close-coupled cooling delivers cold air near heat loads to discourage recirculation and increase energy efficiency. An included 71-inch flexible hose lets you aim the cold air to a specific spot, such as an overheated rack enclosure or an 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 and filters the air, providing better air quality that can enhance operating conditions and equipment reliability. 

Special Commercial-Grade Components for Reliable Performance
With a 100-percent duty cycle, the SRCOOL12K 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. Upgraded firmware allows the compressor to cycle on and off while the evaporator fan stays on to prevent icing in high-humidity environments.

Add an Optional Remote Management Accessory for 24/7 Monitoring and Control
Install the optional SRCOOLNETLX 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 SRCOOL12K requires no disruptive construction projects or costly service calls from plumbers or 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. An upgraded motor-start capacitor with a larger capacity ensures a dependable startup.

2-Year Warranty
The SRCOOL12K is backed by a robust 2-year warranty, ensuring reliability and performance.
