[DC3] Chillers proactive maintenance, scheduled 5 months ago
We will do the semi-annual maintenance of the chillers from 04 to 13 September 2018, depending on the manufacturer’s maintenance range. Operations will be performed by the manufacturer and supervised by our maintainer, according to the following schedule:
Tue 04/09 Chiller n°1 Substation A
Wed 05/09 Chiller n°2 Substation A
Thu 06/09 Chiller n°3 Substation A
Fri 07/09 Chiller n°4 Substation B
Mon 10/09 Chiller n°5 Substation B
Tue 11/09 Chiller n°6 Substation B
Wed 12/09 Chiller n°7 Substation C
Thu 13/09 Chiller n°8 Substation C
Substations A and B supply the chilled water network of the computer halls.
Substation C supplies the chilled water network of the operators halls and the air handling units.
Since only one refrigeration unit is switched off at the same time, only the redundancy is degraded.
