B 15 IT by Master is a professional three-phase electric heater designed to heat medium-to-large sized environments, whether industrial, commercial, or residential. With a capacity of approximately 1700 m³/h, it offers wide coverage while maintaining compact dimensions.

Made with a robust stainless steel structure of high resistance and quiet operation, the Master B 15 IT is considered one of the best hot air generators available. Its design without open flames or harmful emissions ensures safety even in closed or poorly ventilated areas, and does not require oxygen consumption.



The professional portable hot air generators in the Master line work by exploiting the Joule effect: the axial fan passes air through electric heating elements, heating it. The heating system is regulated by a thermostat that monitors the room temperature and another that prevents overheating.


These heat generators include a motor with thermal protection, equipped with an automatic reset function, along with a summer-winter switch that regulates ventilation.

This Master heater is entirely produced in Italy. Made in Italy is synonymous with accuracy and high technical quality.





Master offers the option to extend the product warranty up to 3 years. Visit the dedicated page to check the conditions and register your product.
