US-based company Comrent has released custom-engineered solution it said is the first in the industry to provide in-aisle, water-cooled server simulation for end-to-end electrical and thermal testing of the chiller and chilled-water loop.

It said its modular ESX water-cooled server simulator system removes some of the cost and inconvenience seen as a barrier to installing liquid-cooled equipment or water cooled devices at rack level of close to the rack.

It also said it offers more control when carrying out data center chiller plant and chilled-water loop validation testing.

ComRent President and CEO Clayton Taylor said data center commissioning professionals have had little choice in how to carry out verification testing of water-cooled, high-density mainframes and other equipment.

“They were forced to either purchase expensive, heavy work-around solutions that were not designed to give accurate testing results in a modern, water-cooled environment, or perform separate tests on chiller plant and the chilled-water loop.” Taylor said.

“The ComRent EXLS server simulation load bank enables end-to-end testing of both chiller plant and chilled-water loop flow rates in addition to validating the Delta T (temperature rise) in a true operating environment.”

ComRent said the EXL S is 70% lighter than other water-cooled load banks and is easier to position on the raised floor at chilled water loop taps.

It offers variable BTU settings and variable flow control using electronic servos networked and managed as a complete system from an Android device or a laptop computer.

It uses a tank-less heat exchanger design, using 18 to 36 gallons of water.

ComRent, which provides rentable load banks for testing data center equipment, said it is renting its solution in two configurations: 250kw and 500kw.
