Replacement of Evaporative Condenser

To complete the replacement of an ammonia NH3 – R717 evaporative condenser, a backup refrigeration unit was rented to maintain cooling capacity throughout the works. The old condenser was dismantled and a new unit was supplied and installed, including connection to the existing ammonia, electrical, and hydraulic networks.

To ensure quality, appropriate non-destructive tests (NDT) were carried out on network tightness via section pressurisation and radiographic testing.
