Enware, as the leading brand of Thermostatic Mixing Valves in Australia takes the responsibility very seriously for keeping users safe, the water supply healthy and for continuing to deliver enhanced performance.
Hot Water Flushing Capability To Minimise Bacteria Risk In Plumbing Systems
This year we have been working hard to further improve the features and performance of our strutted, NSW Health Approved TMV Aquablend™ 1500 which now incorporates a significant new feature - a thermal flush mechanism. A major step forward in legionella control, the thermal flush will allow the valve to pass hot water through the valve during critical decontamination / maintenance functions, without changing the temperature setting.
There is a slight difference in appearance on the new ATM700 with a red lock shield (cap) with “Thermal Flush” embossed on it.
The Aquablend™ 1500 valve will now be capable of being set at temperatures up to 50°C (previously 48°C) and will function as normal if the thermal flush is not used.
All approvals and compliance to standards are unchanged - the valve is Australian Made and compliant to AS4032.1 with full NSW Health approved and a 5 Year Warranty*
Previous models (Post 2008) of the Aquablend™ 1500, 1000 and 2000 can be upgraded with a comprehensive Upgrade Kit - ATMS242. All service kits for Aquablend™ TMV’s will be supplied with the Upgrade Kit and the lock shield will be marked “upgrade” so it is identifiable after it has been installed. The kit will include the lock shield, thermostat, top cap, mixing tube and o-ring.
