In the “world” of thermoregulation, with regard to the problems linked to the processes of heating and / or cooling of metal bodies and liquid and gaseous fluids, thermoregulators are indispensable components for temperature control and regulation. Said thermoregulators have excellent mechanical and precision qualities and are suitable for all types of controls and adjustments, even when the working conditions are “severe”. The materials and components used for the construction of the thermoregulators allow use in all liquid and gaseous fluids, even at high temperatures.
