    • The Warmup Mixing Unit is required where the flow temperature from the heat source does or could exceed the design water temperature of the floor heating system, this also includes all heat sources that intermittently ‘over heat’ due to sterilisation cycle or uncontrolled heating.

      • Minimises both mechanical and hydraulic noise
      • The unique mixing unit provides full 3-way mixing control making it compatible with all heat sources
      • Featuring integral primary and secondary circuit bypasses, the mixing unit makes commissioning easy without needing to purchase expensive extras
      • When set to operate in its constant pressure mode, this 70kPa circulator makes setting flow meters simple, with flow rates remaining constant whatever the manifold load is
      • anti-tamper device ensuring it continues to operate efficiently.
