Working in Croydon

How fast can a technician service Carel equipment at a data centre & critical cooling site in Croydon?
Croydon sits on the R21 and N12, so our Kempton Park dispatch reaches most Croydon Industrial sites inside a standard callout window. Emergency commissioning & handover runs 24/7 because thermal runaway trips racks within minutes.
