The furnace is used to preheat combustion air up to 500 °C and is portable. This enables it to be close to the furnaces that use burners with preheated air.

• Maximum furnace power = 150 KW.
• Maximum temperature = 900 °C.
• Maximum air flow Qmax = 600 Nm3/h @ 400 °C.
• N° 1 “K” series thermocoupls for air thermoregulation + n° 1 “K” series thermocouple for the combustion chamber thermoregulation.
