The L.B. White Commander™ Series is a make-up air/hidden flame unit offered in two versions as 500,000 or 1,000,000 BTU. The Commander™ Series is built and designed in the USA using industry leading knowledge for rugged and efficient products. The heater has the impressive ability to control the discharge temperature; a feature that is uncommon with most portable gas heat systems. This feature allows the operator to use the machine for a large variety of situations. It helps avoid overheating smaller spaces, while allowing the flexibility to turn up the heater discharge for large heating applications such as warehouses and other industrial spaces.

The L.B. White Commander 1000 Portable Makeup Air Heater has an enclosed flame, unlike open-barrel heater systems that have exposed flames. The machine only requires a 20 amp 230v breaker for power. The blower system is capable of ducting up to 100′ in length, which can help deliver heat to areas not easily accessible. in addition to helping improve air quality of the building, the machine can assist with removing moisture and drying structures after floods.
