Slide 8UCSB CMS Weekly Status MeetingCMS 4-Hybrid Test System Sam Burke EE Chiller Antifreeze required to prevent freezing of Peltier Water cooling lines during power failure. à If unit is powered down with cold box at -20 deg C the cooling water will turn to ice unless 50% solution of antifreeze is used. This will freeze at -34 deg C.
