Temperature controller ARI-TEMPTROL 12.771 DN25

Temperature controller ARI-TEMPTROL 12.771 DN25

The ARI-TEMPTROL temperature controller is a directly controlled proportional controller designed to control the temperature of liquid, gaseous and vapor media.
The thermostat is a combination of a regulator and a valve and works on the principle of liquid expansion with increasing temperature.

Areas of use:

ARI-Temptrol temperature controllers are used in heating and ventilation systems in industry, housing construction, commercial and warehouse premises, shipbuilding, and cooling systems.

Peculiarities:

• The flanged valve is balanced by a stainless steel bellows, which ensures high-precision valve operation even with significant pressure drops;
• Accurate and simple setting of the set temperature;
• Low inertia of the thermostat when equipped with a spiral sensor;
• Has protection against temperature increase above the set;
• Existence of three sizes of a thermostatic element for an optimum choice of a range of proportionality (control error);
• Thermostatic elements with different time constants;
• Possibility of a complete set with the device of manual control of the valve.
