Advanced Dual Circuit Cooling for Data Center Applications The Liebert DS provides a complete environmental control package, including both precision air conditioning as well as humidity control-no matter what the temperature is outside. Both upflow and downflow configurations are available to cover raised floor and non-raised applications. 
Downflow Supply- Designed for raised-floor applications, the downflow air supply configuration is commonly found in data centers and other similar facilities housing sensitive electronic equipment. | 
Top Front Supply with Plenum & Grille and Front Return- In-the-space applications without ductwork, such as Telecommunications, Networks and Switching Centers, benefit from this economical configuration. Optional high filtration may be desirable. |
The Liebert DS product line has been designed to cover the widest possible range of application requirements. These include choice of airflow configuration, cooling method options and many other selections that will create the most effective and efficient system for your facility. The compressorized systems of the Liebert DS feature direct expansion operation in four types of cooling configurations: air cooled, water cooled, glycol cooled and the GLYCOOL free-cooling option. 
A look inside the Liebert DS
Temperature and Humidity Control The environmental control system must be able to sense and react to temperature and humidity fluctuations far too small for building HVAC systems to control. The Liebert DS is capable of control to within ±1°F (°C) and ±1% RH. By analyzing the rate of change in temperature or the moisture content in the environment, the control system anticipates what is going to happen in the room, not simply responding to what has happened. Designed for Energy Efficiency Liebert is dedicated to providing maximum energy efficiency in its precision cooling systems without compromising the accuracy and reliability demanded by sensitive electronics. All enhancements to energy efficiency are designed to reduce operating time of key components and increase the Mean Time Between Failure. This is accomplished by taking advantage of alternate sources of cooling by minimizing compressor operation when heat loads in the conditioned space are lower. Energy savings is also gained through the use of high efficiency components such as advanced digital scroll and 4-step semi-hermetic compressors.

Liebert DS
Precision Cooling System
The Liebert DS offers many benefits: Reliability: - Microprocessor technology adds automatic sequencing of components to even wear and extend service life.
- An alarm system and self-diagnostics provide rapid troubleshooting and can prevent a problem before it affects the electronic equipment room environment.
- Air delivery system designed for optimized air distribution and long service life.
- Corrosion resistant frame and cabinet.
Flexibility: - Available in both downflow and upflow configurations to cover a wide range of room applications.
- Choice of compressors to match performance and energy efficiency requirements.
- Front access provides easy serviceability and saves valuable floor space.
- Modular frame construction allows even more flexibility in meeting specific needs for installation-frame can be field-separated into three sections.
- Built-in humidity control and reheat function.
- Liebert iCOM control system brings high-level supervision to multiple units allowing them to work together as a single system to optimize room performance.
- Available with R-407C environmentally friendly refrigerant or R-22 standard refrigerant.
Low Total Cost Of Ownership: - Energy efficiency options and configurations can save money and even pay back part of your investment over the life of the product.
- Built for serviceability, with many components-such as the Paradenser cleanable condenser-designed to be maintained rather than replaced.
- Specifically designed for the demanding requirements of year-round operation, the Liebert DS is actually less expensive to operate over its life cycle compared to both comfort cooling equipment and competitive precision air conditioning products.
Ideally Suited For: - Data Centers
- Telecom/CATV
- Computer Rooms
- Labs And Testing
- Network Operations Centers
