BELGIUM: Trane has introduced a new R1234ze chiller specifically designed to meet the stringent requirements of high temperature data centres.
Joining Trane’s Sintesis Excellent range, the upgraded GVAF chillers feature new magnetic bearing centrifugal compressors optimised for handling high water temperatures typical for data centres. The inclusion of Trane’s latest Symbio 800 adaptive controller is designed to provide intelligent control over the operational reliability and efficiency of the cooling system.
Like other models in the Sintesis Excellent range, the GVAF chiller operates on low GWP refrigerant R1234ze.
“For years Trane has worked closely with the data centres helping them to handle the heat loads associated with computational processes. Today we’re making another step forward, introducing chillers that embrace the latest technology innovations to better handle the specific and growing cooling needs of data centres,” commented Trane Europe portfolio manager Erik van Oossanen.
“With Symbio 800 we optimise the operations of the chiller and its elements like fans, compressors, etc, and with Trane’s system controllers we can efficiently control the entire chiller plant of multiple chillers operating in the same time.”
New features specifically designed for the GVAF models include new, embedded software designed to react quicker and restart the unit faster in case of an unexpected shutdown; enhanced connectivity with the capability to support numerous communication protocols; UPS.
The Symbio 800 controller can be connected to a safe power source, eliminating the need to reboot the controller in case of power loss.
For additional reliability the GVAF features Trane’s Rapid Restart setting to reduce the time needed to reach the full capacity after shutdown. It also features an automated transfer switch allowing to connect the unit to two power sources. The unit will detect any power supply cut off and automatically switch to the auxiliary source ensuring continuous operations.
The GVAF has a reduced footprint, three different pressure levels for hydraulic modules and various water connections options. It also includes upgraded free-cooling system tuned to the rising temperatures of the modern data centres.
