CtrlS Datacenters has recently announced today that it has partnered with Emerson Network Power India to become one of the first data centers in India to deploy water-based cooling technology. The company will completely replace the air-cooled system at its data center with 15 Liebert PeX cooling systems from Emerson.

The new system uses water-based heat transfer technology that converts water into cool air which is then pushed into the data center through the indoor units. The system is also designed to ensure that water does not enter inside at any point of time thereby eliminating any risk to IT infrastructure. With the new cooling system, CtrlS expects to save 30 per cent on energy costs annually.

“This innovation has further strengthened our value proposition for global outsourcing of data centre services to India,” said Sridhar Reddy, Chairman and Managing Director, CtrlS. “We have always been at the forefront of embracing innovation. This new cooling system is part of our efforts to bring in energy efficiencies and save on costs which can be passed on to our customers. Moreover, this is a completely environment friendly system with zero carbon dioxide emission” added Reddy.  

In preparation, the company made numerous changes at its data center. It implemented a state-of-the-art water treatment and chemical plant to ensure quality water supply along with computational fluid dynamics (CFD) to detect thermal problems and variable air volume (VAV) to manage the variable cooling requirements for high density racks.  The VAV technique helps remove heat and control air conditioning systems by keeping one part of the exchanger temperature constant. Airflow is regulated according to the demand.

In the data center, the water-cooled condenser units are placed outdoors to prevent water from entering the data center. The cooling units are placed near the indoor units for maximum cooling efficiency. Water is pumped from cooling towers and a piping mechanism takes it to the condenser and back. In conjunction with an efficient floor layout and improved raised floor, CtrlS can effectively reduce energy losses with the new cooling system.
