An Aquazone buffer tank is often incorporated into a chilled water or heating water system that has insufficient water volume throughout the piping network in relation to the chiller or boiler capacity. By adding a buffer tank to the system, extra volume is created which provides additional “buffer” capacity and eliminates the problems such as excessive compressor cycling, poor temperature control and erratic system operation. In some instances when a large building is undergoing refurbishments or extensions, the capital expenditure of a larger chiller can be deferred, by installing large buffer tanks and utilizing the existing chiller.
These tanks are insulated so that the stored water maintains its chilled temperature. This allows the tank to charge up during off peak periods, thus reducing the chillers workload during peak periods throughout the next day.
- Capacities ranging from 300 – 90,000 Litres
- Tanks are generally pre-insulated and cladded in accordance with the NCC requirement
- Wide range of accessories available including isolating valves, pipes, internal baffles and gauges.
WE CAN HELP YOU CHOOSE THE RIGHT Buffer Tanks FOR YOUR PROJECT
Aquazone tanks are available as either bare tanks and fully pre-insulated and cladded, with transport protection.
What makes the Aquazone range of buffer tanks unique is the strict compliance & necessary documentation to AS1210, AS4343, AS1554 and other pressure vessel related standards. Masterflow also designs and fabricates tanks compliant with ASME standards as required. Extensive research, modelling and field testing has allowed Masterflow to determine how to achieve maximum effective capacity, whilst minimising pressure loss and creating optimum flow direction within the tank. All designs are certified by independent pressure vessel certifiers. Insulation is fire retardant and environmentally friendly, conforming to EcoGreen code. Tanks

Frequently asked Questions
AS1210 page 21 clause 1.8.12 calls up AS4343 as the code for determining Pressure Vessel Hazard Levels. Therefore based on AS4343:2014 page 10 clause 2.2.6:
Your PV = 7500 x 1.6 = 12,000 (below 100,000 MPa.L)
Water with Design Temp above 0 deg C up to 65 deg C max
Will give you the Hazard Level “E” as correct
With the standards they now have ongoing codes covering additions for Pressure Vessels such as:- AS4458 for Pressure Equipment – Manufacture; AS3892 for Pressure Equipment – Installation; AS3788 for Pressure Equipment – In Service Inspection. (A good money maker for the Standards Supplier)
All these codes are referenced within AS1210 and with your Maintenance and Operation Instructions for your client, you should call up AS3892 if they are installing and AS3788 for the ongoing inspections that is required by WorkCover.
When you call up these code you are then putting the risk / code requirements on the client to do their part and takes you out of the equation / insurance claims etc.
Current regulations prohibit the use of the ODS material more and more, requiring MSDS and TDS documents to prove it.
You can be assured all the products we use comply with all Australian Standards for this and this is shown on the TDS documents.
