The Thermo-Air (TER) and Thermo-Zone (ZON) electric duct heaters are unique to Thermolec. Both are available with 6” – 12” round duct connections and up to 12 kW of electric heat in single phase power. Both units come with an electronic airflow sensor and duct temperature sensor. The TER has a duct stat to control temperature in the duct. The ZON comes with a wall stat to control room temperature.
