A diesel direct heater with a 150,000 BTU output is a powerful heating solution ideal for large, well-ventilated spaces such as construction sites, warehouses, and workshops. Designed for high-performance, it burns diesel fuel directly to generate intense heat, which is then rapidly distributed by a built-in fan. This heater is capable of warming substantial areas quickly, making it suitable for challenging environments where fast, efficient heating is required. Equipped with safety features like flame failure shut-off and overheat protection, the diesel direct heater ensures reliable and safe operation. Its robust construction and portability make it a dependable choice for professional and industrial heating needs.
