1. Cooling water maintenance in XHPSC: replacement of valves taking place and the filling back is ongoing; expected that cooling water will be back today.
2. Temperature in XHEXP1 showed 23.8C and 64% humidity as of Friday 18.07. When cooling water is back today please wait as humidity is too high and condensation may happen;
dehumidifying system is still limited due to maintenance but precision air conditions will return and help with dehumidification in Hall and labs.
3. Due to construction for HXS please avoid entering or leaving XDT7 to XHEXP1.
- Janusz Szuba asks on the cooling water redundant pumps: until the end of the current week the redundant system will not work and there is a risk that primary pumps go OFF in case of a power outage.
Unclear how long it takes to recover the system in case of this failure (depends if happens during day or night). As consequence the rack rooms may be affected due to heat. To be further discussed.
