The B-257-0 Siroco Sanoa Heater D55 is built for applications that need strong airflow and reliable heat delivery in a compact package. This 12V water heater uses a version D front panel with 6 x Ø55 mm sleeves, making it ideal for setups where ducted air distribution is required across multiple discharge points.
Because it offers 3-speed ventilation, operators can better control comfort and airflow depending on cab size and operating conditions. The heater also uses Ø16 mm hose connections and comes with the connector included, helping simplify installation into compatible heating systems.
With 605 m³/h nominal airflow and 10.1 kW heating capacity, this Sanoa D55 heater is well suited for demanding cab heating applications in industrial, construction, agricultural, and specialty vehicle environments.
