We have extensive experience in chiller replacement without downtime
In 2010 we completed a callenging project for a clobal IT provider to change 2 180kw intelligent free cooling chillers along with the decommissioning and removal of the existing R22 chillers.
To faciliate the work our engineers had first to support the existing data centre with 200Kw of temporayr cooling, for an 8 week period, ensuring that data centre conditions were met throughout. Many of the clients hosted in the data centre were global companies and it was vital that there was no 'downtime'.
We installed a temporary chiller and air handling units with supply air ducting into the existing data centre and used the existing room CRAC units as circulation units to retain the existing sub floor pressurisation & air flow patterns. Once complete an extensive test was undertaken with comprehensive data logging of the rooms and sample racks to establish 'base line' conditions and then verify no change once the temporary cooling package was enabled.
