Does the Liebert DS cost more to operate than a regular building air conditioning system?

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.

Does this type of cooling system use a lot more energy?

No, due to a greater sensible heat removal capability compared to a comfort cooling system of the same size, the Liebert DS will save money and even pay back part of your investment over the life of the system.

What if you don't have a raised floor in your data center?

The Liebert DS is available in upflow models for use in facilities without raised flooring, as well as downflow models designed to be used with raised floors.

Why is a Liebert DS precision cooling system better than ordinary building air conditioning?

The Liebert DS offers a much higher level of reliability compared to comfort cooling systems. It uses rugged refrigeration components that are designed to operate 24 hours a day, 365 days a year. The Liebert DS also provides the precise temperature and humidity control required by sensitive electronic computer equipment.
