Tender Description

This project is to upgrade the existing compressed air system at Westmead Children’s Hospital which provides medical grade air to patients throughout building 5, 6, 8, & 9 for breathing outlets, venturi suction and dental air. The system broadly comprises the following items:

* Three (3) reciprocating compressors operating at 93 L/s each
* Three (3) after coolers, one servicing each of the compressors
* Two (2) pressure vessels with a capacity of 4800L each functioning at a design pressure of 710kPa.
* Two (2) refrigeration driers operating at a maximum flow rate of 266 L/s
* Two (2) sets of staged filtration downstream of each of the refrigeration driers.

A large portion of the aforementioned compressed air system has reached the end of its design life and requires replacement. This project involves the upgrading of the compressed air system and incorporating the above mentioned items with the following additions and changes below.

* Three new compressors serving a similar duty function
* One new refrigeration drier. The second unit was replaced under maintenance in the last 2 years.
* New airstream filtration systems
* All isolations valves to be replaced

One important consideration for the replacement of this equipment is the maximum demand from each piece of equipment. There is currently a 200A three phase essential supply provided to the plant room which is often close to capacity on start-up of the existing compressors.
