  • Caleffi LEGIOMIX®
    Caleffi Introduces New LEGIOMIX® Electronic Mixing Valve!...

  • The Caleffi LEGIOMIX® is an advanced, electronically controlled point-of-distribution Electronic Mixing Valve for commercial domestic hot water systems. It maintains the temperature of the domestic hot water delivered to the user when there are variations in the temperature and pressure of the hot and cold water at the inlet or in the draw-off flow rate. The LEGIOMIX® electronic mixing valve provides precise temperature control over very low and very high flow rate demand, minimal pressure drop with a ball valve control element, automatic self-cleaning to prevent scale formation and easy-to-use digital interface with data logging, alarming and status indication.

    The LEGIOMIX® electronic mixing valve is furnished with a controller with LCD user interface that provides a set of programs for circuit thermal disinfection to kill Legionella and is configurable via keypad or local or remote computer. Depending on the type of system and habits of the user, temperature levels and operation times can be programmed as desired. In addition, it comes standard with monitoring and remote control connections. 

  • Caleffi TANKMIXER™
    Caleffi TANKMIXER™ Quick Connect Kit is the Perfect Mix...

  • The Caleffi TANKMIXER™ 520 Series is a perfect mixing valve solution to maximize the capacity of modern high efficiency water heaters and minimize installation time. It comes packaged in a complete quick connect kit with everything needed for fast installation. Including union fittings, industry-exclusive press connections and a cold water cross with check valve to prevent cross flow.

  • Caleffi QuickSetter™
    The Caleffi QuickSetter™ Providing You Fast, Easy and Accurate Balancing...

  • Traditional static balancing valves require use of differential pressure instruments. Not only time consuming to hook up and calibrate, DP instruments require involved training. The Caleffi QuickSetter™ 132 Series with its’ built-in visual flow meter simplifies balancing by allowing the contractor to adjust flow while viewing flow rate directly on the valve itself. Zone balancing becomes fast, easy and accurate.
