Group thermostatic mixing valves PREMIX SECURITY /

• Automatic anti-scalding safety: automatic shut-off if cold water fails
• Comfort: temperature stability regardless of variations in pressure, flow rate or temperature in the system
• Solution against Legionnaires' disease: complies with the UK HSE technical guidance "HSG274 Part 2" in 2014
• Installation: at the hot water system outlet (HW)

PREMIX SECURITY
Group thermostatic mixing valve for circulating loops 44 - 58°C

THERMOSTATIC MIXING VALVES

• Anti-scalding safety.
• Regulates temperature variations.
• Filters and non-return valves can be accessed from the outside
without removing the mechanism.
• Thermal shocks are possible.
• Interchangeable cartridge with thermostatic cell.
• High-resistance chrome-plated brass body.
• Maximum hot water temperature: 85°C.
• Differential hot water / mixed water: 15°C minimum.
• Pressure differences at the inlets: 1 bar maximum (0.5 bar recommended).
• Minimum pressure / maximum: 1 - 10 bar (1 - 5 bar recommended).
• Left hand side hot water inlet (red ring) and right hand side cold water inlet (blue ring).
• Mixed water outlet at the top (purple ring).
• For bottom outlet: unscrew / place blanking cap at the top and outlet connector
at the bottom.
• Energy savings: heat loss minimised (comparison between a circulating loop
at 55°C and a non-circulating system at 70°C).
• Safety and increased system lifespan
(Hot water at >65°C leads to premature ageing within the system).
• Maximum temperature limiter, can be adjusted by the installer.
• Reduced risk of scalding by reducing the temperature at the production outlet.
• 30-year warranty.
