Large-Capacity Self-Contained Rack-Mount Cooling Unit Ideal for Your Server Room
The SmartRack® 5.5 kW Self-Cooling Server Rack is designed for server rooms or similar single-rack installations, particularly at the edge of a network. It provides closed-loop precision cooling for reliably protecting mission-critical equipment from overheating in environments without room for a bulky in-row unit. It is also convenient for customers looking to avoid the time and expense of a more complex HVAC solution. The self-contained and close-coupled SRCOOL5KWRM42U is delivered as a kit with the cooling unit pre-installed at the bottom of the 42U rack.

5.5kW Cooling Capacity Protects Your Equipment and Prevents Expensive Downtime
This precision air conditioning system delivers 5.5 kW (18,766 BTU) of cooling to your rack equipment to help prevent sudden shutdowns, malfunctions and other failures caused by overheating or fluctuating temperatures. The SRCOOL5KWRM42U is ideal for tight-fitting edge server rooms and other mission-critical IT applications, including retail and commercial outlets (storefronts and branch offices), light industrial environments (factories and warehouses) and research/development locations (laboratories and workshops).

Rack AC Unit Focuses Cold Air Where It’s Most Needed
The SRCOOL5KWRM42U uses environmentally friendly R410A refrigerant to focus cold air directly into the rack to efficiently cool equipment. Variable fan speed adjusts the cooling output to the need of the IT load to prevent on/off cycling and large temperature swings.  The rack is delivered with a full set of 1U blanks pre-installed on the rack's front rails, which funnels the cold air through the IT equipment only. The 1U blanks should only be removed to install IT equipment in order to optimize the flow of cold air through IT equipment from  the front of the rack to the rear of the rack. A color touchscreen LCD allows convenient status monitoring and diagnostics right at your fingertips. 

Features 3 User-Selectable Condensate Removal Methods
You may choose from three condensate removal methods. Condensate evaporation is defaulted (1), but you may re-configure it to water pump removal (2) or gravity condensate removal (3) if your location has a water drain nearby. In case of a leak, the SRCOOL5KWRM42U includes internal leak detection, which will automatically turn off the cooling system to prevent condensate from entering the rack.

Commercial-Grade Components for Reliable Performance
With a 100-percent duty cycle, the SRCOOL5KWRM42U 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.

Emergency Vent Allows Hot Air to Vent Out During Power Emergencies
The emergency fallback ventilation system activates in the case of a cooling failure and if the inside rack temperature reaches 104°F (40°C). The emergency vents have embedded thermal sensors, which trigger the vents to open, allowing the hot air to escape the rack and protect critical IT equipment from overheating. If the emergency vents open, an alert will be sent to notify the IT manager.

Remote Network Interface Offers 24/7 Monitoring and Control
The built-in WEBCARDLXMINI network management card adds peace of mind when monitoring remotely. You can configure settings, events and actions, as well as power the unit on and off or graph temperatures over time without being on site. You can also receive configurable alarm notifications via email, SMS or SNMP. The SRCOOL5KWRM42U will restart automatically after a power failure.

Rack Enclosure Keeps Important Equipment Secure
The front door with clear acrylic windows and split rear door lock securely with the included keys to help prevent damage, tampering or theft. The bottom is designed to accommodate the cooling unit’s hot air exhaust duct.

Convenient Space-Saving Design
The 12U cooling unit is rack-mounted at the bottom of the 42U enclosure to save valuable rack space for PDUs, UPS systems, servers and cabling. With 3U of clearance required above the cooling unit, 27U is available for mounting rack equipment. This unit does not require a professional HVAC contractor, as the unit is pre-charged with refrigerant. Note: An optional 12-foot input power cable is included. Eaton offers full installation as part of a startup service part number.
