Power Systems Australia  was successful in winning a project to supply and install two very quiet generators at a Melbourne water board. As this sewage plant is located in the suburbs with residential properties on the boundary, noise was the critical factor.

PSA were chosen for their in house manufacturing and contract management expertise, this project involved packaging of a 500 kVA and a 1,000 kVA generators into a 20’and 40’ container as well as civil and electrical works.  

The enclosures were designed to meet 70 db(A) @ 1M so that 38 db(A) would be achieved at the residential boundaries. Considering that the generator noise is 105 db(A) @ 1M  and the Exhaust noise level is 128 db(A) this took considerable engineering and acoustic design.

Special considerations were also taken for OH&S and the environment with ingress into the containers not required for operation only for servicing. The environmental considerations were bunding of fuel, oil and coolants.
