South Africa, Cape Town: A generator set installation at a private hospital will soon be commissioned by Zest WEG, providing a plug-and-play solution with high reliability and minimal downtime.
“In a design that suited the hospital’s severe space constraints, Zest WEG built the generator, transformer and remote radiator into special ISO shipping containers in a double-stack configuration,” said Johannes Nel, operations manager – production at Zest WEG. “The contract also included the refurbishment of the client’s existing 1,000 KVA 400 V MTU open-type generator which was included in the solution.”
A dry-type step-up transformer allows the generator to connect to the 11 KV council electricity supply council supply, which will reduce hospital downtime during commissioning. The resin-sealed transformer also provides a long-lasting solution with low maintenance and a high safety factor due to the absence of oil as a coolant.
The new genset expands the hospital’s standby generating capacity to 1 MVA continuous rating, allowing 100 % of the institution’s functions to continue as normal during periods of load-shedding. Nel also highlights that reliable supply was key to the hospital’s safe and efficient operation, whether from mains or back-up supply.
To reduce the project lead time as much as possible, the delivery of certain imported components was arranged well in advance. The containerised solution was constructed and extensively tested at the Zest WEG genset manufacturing facility in Epping, saving time during installation.
In addition to conducting a complete engine rewiring, Zest WEG also upgraded the generator controller, giving the customer improved ability to monitor the generator’s operation during load-shedding. The modern controls help protect the generator and optimise the lifespan of critical equipment.
The final commissioning and handover to the client is projected for the end of May.
