/ Thermostatic mixing valves PREMIX COMFORT, COMPACT and NANO

No circulating loop, PREMIX COMFORT, COMPACT or NANO and duty flush system

In installations where there is no circulating loop, stagnating water at temperatures below 50°C can cause Legionella bacteria to develop.
In older installations where a circulating loop is not possible, we recommend the solution below to combat bacterial proliferation.

Solutions:
• PREMIX COMFORT, COMPACT or NANO to lower the temperature of the water at the points-of-use to a maximum of 41°C (HSG 274 Part 2, 2014).
• DELABIE electronic mixers, taps or valves with automatic duty flush can be installed at the extreme end of each distribution arm (as a minimum) to prevent
any bacterial development: automatic duty flush for ~60 seconds every 24 hours after the last use.
