Hornsby Shire Council Administration Building

The Hornsby Shire Council Administration Building is the meeting hub of over a dozen council administrators that serve their community through their spearheading of a variety of council functions, including ​​Corporate Support, Community and Environment, Planning and Compliance, and Infrastructure and Major Projects. 

The building’s existing buffer tanks had reached the end of their lifecycle, with the NSW Government’s mechanical contractor entrusting Masterflow to supply their replacement.

Our Process: 

Masterflow produced 2 custom-made buffer tanks for this client, both constructed from Grade 316 stainless steel, chosen for its excellent resistance to corrosion. Both tanks featured an internal baffle, which serves to ensure ideal water circulation and complete use of the tank’s volume. 

Both tanks were rated to 10 bar, pre-insulated and cladded with closed-cell, cross-linked polyethylene and fitted with IP56 weatherproofing upgrades in light of the building’s outdoor plantroom. 

A 500L Heating Hot Water and 800L Chilled Hot Water tank were supplied, with the system now featuring a dual refill unit with an exceptional monitoring and control system. Its main isolator switch protects the system from voltage fluctuations and makes for easier maintenance as it can be quickly disconnected from power. 

The dual refill unit also boasts an alarm display screen with both audible and visual alerts to ensure vital signals are not missed, and a touch screen interface for intuitive and in-depth calibration.  

Had these components been delivered by separate suppliers rather than pre-assembled and delivered synchronously by a single supplier, the overwhelming likelihood is that delays would have occurred as some suppliers would arrive earlier than others, and a variety of assemblies including hot works would have taken place on the client’s site, rather than in our workshop.





With our stellar custom-made tanks packaged to eliminate any transit damage, the made-to-last, BMS-ready units were supplied in immaculate condition with the right specs in mind from the moment they were designed. 

As Masterflow takes every aspect of our client’s needs into account, from space requirements to the electrical supply system used, we are able to consistently deliver headache-free solutions that offer our clients a smooth installation process and product experience.
