| SysTemp G SysTemp G G series close control air conditioners have constructional and operating characteristics suitable for meeting the design criteria of the latest generation data centers. When designing air conditioning systems for large data centers, the need for electrical cable housing and the enormous air volumes required to cool down the servers have made it essential to increase the height of raised floors up to the current 550/1,000-millimetre level.
SysTemp G | Air Conditioners with downflow air supply Standard version for data center perimetral installation: the height of the raised floor must be at least 550 mm. Standard version for data center perimetral installation with raised floor height less than 550 mm. In this case the stand, having a fixed height of 550 mm provided with side closing panels, must be installed above the floor. However, please make sure that the ceiling height allows good air intake.
