Freeze Protection Thermostat with switch – ANDFST-0,6

Freeze Protection Thermostat ANDFST-0,6 with freeze-protection switch is used for downstream temperature control of water-air heaters in ventilation and air-conditioning system in order to prevent frost damage.

The ANDFST-0,6 freeze protection thermostat with switch features:

• a remarkably small differential gap,
• high reproducibility,
• and an automatic reset function.

Freeze protection thermostats are essential components in HVAC systems, particularly in regions where subzero temperatures are common. These thermostats are designed to prevent pipes, coils, and other critical components from freezing, which could otherwise lead to costly damage and system failures.

By monitoring ambient or surface temperatures, freeze protection thermostats activate heating elements, such as trace heaters or preheat coils, when temperatures approach freezing thresholds. This ensures that water and other fluids within the HVAC system remain in a liquid state, safeguarding the system’s functionality during cold weather. Their role is particularly vital in commercial and industrial buildings with extensive ductwork or exposed piping that are prone to temperature fluctuations.

In addition to preventing damage, freeze protection thermostats enhance energy efficiency and operational reliability.

Andivi’s ANDFST-0,6 model is equipped with advanced sensing technology and programmable features, allowing precise temperature control and minimizing energy consumption by activating heating only when necessary. This functionality is especially beneficial in HVAC systems for green buildings, where sustainability is a priority.

Their integration into building automation systems further enhances their effectiveness, allowing remote monitoring and control, which is invaluable for facilities management teams overseeing large-scale HVAC systems.
