Eaton SmartRack Self-Cooling 42U Server Rack Enclosure with Single-Phase 5.5 kW (18,766 BTU) Cooling Unit, 208V, 60 Hz

Eaton SmartRack Self-Cooling 42U Server Rack Enclosure with Single-Phase 5.5 kW (18,766 BTU) Cooling Unit, 208V, 60 Hz

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.
