Portable Close-Coupled Rack Cooling System Improves Equipment Performance
SRXCOOL12KA is a portable, compact, self-contained AC cooling unit for server racks. It is designed for areas with heat-sensitive equipment that facility air conditioning can’t reach. By cooling small IT installations or spot cooling individual racks in larger installations, you can protect mission-critical systems without relying on less efficient building-level HVAC or sinking money into costly HVAC upgrades.

Designed Specifically for 230V SAA/RCM Markets
This SmartRack® server cooling system is fitted with an IEC Type I power plug and meets Standards Association of Australia (SAA) and Regulatory Compliance Mark (RCM) approval for use in Australia and surrounding markets. It is ideal for adding discrete 24/7 cooling in IT and network closets, data centers, edge installations, MDFs, IDFs and small server rooms.

12,000 BTU of Cooling Power Protects Your Equipment Against Hazardous High Heat
This data center 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 push buttons and diagnostic LEDs provides vital operating information at a glance. A dual-digit LCD screen displays current temperature in real time.

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. A flexible delivery tube lets you aim 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. The IT-grade 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. 

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 floor drain or water collection tank and saving you time and money. No external condenser, refrigerant piping or professional maintenance is required for simple operation.

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 SRXCOOL12KA requires no disruptive construction projects or costly service calls from plumbers or HVAC specialists. Built-in rolling casters make the 34-kilogram unit easy to install and relocate. The 1.8-meter power cord features an IEC Type I plug that 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.
