Taco’s new LOFlo Mixing Block is a prepackaged unit consisting of a variable-speed injection circulator and constant-speed zone circulator. The variable-speed injection circulator is controlled by a sensor that monitors incoming water temperature to a radiant panel (floor, wall or ceiling) or chilled beam (ceiling). The constant-speed zone circulator is controlled by the room thermostat.
