Duostats

The Clorius Duostats are thermostats, type V, which via two sensing elements in a common hydraulic system act on one and the same control valve. Two basic types are available: Clorius V4.05- or Clorius V4.10 duostat, depending on the preferable proportional band PB, and the valve size.

The sensing elements are two spiral sensors for the ventilation duct or two-rod sensors (a combination of one spiral sensor and one-rod sensor may be supplied in certain combinations). The effect, which the two sensing elements have on the adjustment, is proportional to the liquid volume of the individual sensors. Duostats are therefore available with varying proportions between the liquid volumes of the two sensors (sensor proportions) and in that way they can meet the requirements made by a number of different adjustment problems. As the adjustment result is a weighted average value of the temperatures of the two sensors, nofixed adjustment value can be indicated. Hence, Duostats are not equipped with a temperature scale, but with a marking for adjustment towards higher or lower temperatures, respectively.
