This standalone air conditioning system requires professionally installed piping and electrical connections between the indoor cooling unit and the outdoor condenser, which mounts on a rooftop or condenser yard.


Slim Air Conditioning System Saves Space While Delivering Primary Precision Cooling
This SmartRack® in-row precision air conditioning system is the ideal cooling option for your small-to-medium data center, IT room or other edge location. Typical CRAC/CRHC units are too large for these locations, but the SRCOOLDXRW12 cools your mission-critical equipment while occupying very little floor space, supporting up to 12.8kW (43,686 BTU/hr) of heat load per unit. The cabinet is just 300 millimeters wide, making it easy to position optimally within a row for precision close-coupled cooling. It requires the same front and rear clearance as a standard rack enclosure.

Uses DX Technology to Deliver Cool Air to Loads
This direct expansion (DX) cooling system pulls unconditioned air through the rear of the unit, cools it with condensed refrigerant and delivers it to equipment loads with up to 43,686 BTU/hour and more than 1,475 CFM airflow. EC fans and a variable speed compressor provide variable airflow and constant temperature based on room conditions.

High Cooling Efficiency Saves You Money
Inverter compressor and EC fan technology automatically regulate cooling output to match heat load and conserve energy during off-peak hours, lowering your overall energy costs and lengthening the lifespan of the equipment being cooled. The close-coupled design captures heat at the source to improve energy efficiency by 25% over traditional perimeter CRACs. In addition, the SRCOOLDXRW12 is ideally sized for your small-to-medium data center at virtually any density, saving you the cost of a raised floor or an overbuilt/overprovisioned CRAC unit. It uses eco-friendly R410A refrigerant, reflecting your commitment to environmental responsibility.

Easy to Operate with the Color Touchscreen
You have total control over the SRCOOLDXRW12 using the front-panel color touchscreen interface, which lets you monitor and access system configuration and status information. A built-in controller detects and manages data center temperatures, automatically adjusts cooling levels and supports various control modes. Intelligent temperature control and variable speed technology allow precise airflow and temperature adjustment to match specific load requirements closely without wasting energy on overcooling.

Reconfigure Your Cooling Needs as Your Equipment Needs Change
The modular, in-row cabinet design easily facilitates expansion or movement on its built-in casters, allowing your increasing cooling needs to be reconfigured as your data center grows. A simple redundancy model (N+1) is built in as part of the number of scalable units to be deployed. 

Pre-Installed WEBCARDLXMINI Network Interface Offers 24/7 Access
Remote access to the SRCOOLDXRW12 can save you the time and expense of having someone constantly on-site. The built-in WEBCARDLXMINI lets you manage temperatures, receive alerts, review logs and control settings 24/7 via HTTP(S), menu/CLI via SSH/Telnet and SNMP for integration with management software platforms such as DCIM. The ability to configure settings and monitor alarms off-site can bolster your bottom line.

Designed for Simple Maintenance and Convenience
By placing the SRCOOLDXRW12 close to a rack, you can eliminate hot spots. A water pump automatically drains condensed water and detects the fill pan’s level to avoid leakage. Insulated side panels isolate the unit from external temperature variations. Electrical connections can be routed through either the top or bottom, whichever is more convenient for your application. The SRCOOLDXRW12 supports front or side air discharge. You can configure included panels to direct airflow as necessary to adapt to nearly any environment.
