Temperature control (Is control of your process temperature important?
Many types of steam plants need to be fitted with some form of temperature control. In any process, product quality is often dependent upon accurate temperature control, while heating systems need to be thermostatically controlled in order to maintain optimum comfort conditions. From an energy saving point of view, the ideal temperature is obviously the lowest, which can be accepted for any given application. Spirax self-actuated temperature controllers TR121 control the temperature of the process within an accuracy of +/- 2deg C by controlling the flow of steam.

37 D Temperature Control
The 37 D is a self operated temperature control for use on steam. By virtue of its pilot operation, it has a comparatively small control brand.
