Frost Thermostat - Type EFST-6 (Frost Alarm relay)

EFST-6 is a series of frost alarms designed to protect against frost damage in, for example, the waterbased heating surfaces of ventilation plants.

EFST-6 is a safe and reliable alarm system, developed for use in both large and small installations where there is a need for early warning of low pipe temperature in order to prevent water damage.

EFST-6 has been used successfully in many HVAC installations, either where a redundant alarm is required in relation to the BMS system or where no BMS system for monitoring pipe temperature is installed.

EFST-6 was designed to provide our customers with an advantageous combination of high quality, reliability and low life cycle costs.
