Use in closed loop design. Low Temperature Zone Module K32 replaces conventional injection mixing systems. In conjunction with an electronic reset control and direct drive actuator, the K32 modulates a 3-way valve, diverts and mixes radiant return water with hot water from the boiler. The constant speed system circulator delivers the required water temperature to the radiant loop manifolds.

The K32 can handle radiant load demands of up to 114 KBTU’s@1"module,up to 174 KBTU’s @ 1.25"Module . Your current method of zoning the radiant loops (manifolds, zone valves, etc.) does not change with the installation of the K32. Multiple K32 modules can be used to separate the distinctive temperature requirements between manifolds. No special piping, just 2 connections and your installation in complete.
