Description
Modine PD400AA0181 400000 BTU Propane Propeller Unit Heater 115V 1Ph
The Modine Manufacturing PD400AA0181 is a large-capacity propane-fired propeller unit heater designed for industrial and commercial spaces. It delivers 400,000 BTU/hr of gas input and 320,000 BTU/hr of heat output at elevations up to 2,000 feet, making it suited for heating large warehouses, manufacturing facilities, agricultural buildings, and commercial structures. Unlike cabinet unit heaters, this propeller-style design circulates air directly through a finned heat exchanger without requiring a filter, reducing maintenance requirements.

Applications
Propeller unit heaters like the Modine PD series are a standard choice for heating large, open industrial and commercial spaces — warehouses, distribution centers, manufacturing floors, aircraft hangars, agricultural buildings, and large retail or commercial structures. They hang from the ceiling or structural members and discharge heated air downward and outward into the space, providing fast, efficient spot or whole-building heat without ductwork. Propane-fired models are particularly common where natural gas service is unavailable, such as rural agricultural or industrial sites. At 400,000 BTU input capacity, this unit is sized for very large spaces — typically 10,000 square feet or more depending on climate and insulation — and represents the high end of single-unit commercial heater capacity. The Modine PD series has been a trusted name in industrial gas heating for decades, with the filterless propeller design keeping ongoing maintenance minimal.
This Modine Manufacturing PD400AA0181 400,000 BTU Propane Propeller Unit Heater is in very good, open-box condition — it was acquired from a local fruit processing company that relocated before the unit was ever installed, so it has never been put into service. The cabinet and louver panels show no significant wear; the fan motor, heat exchanger tubes, gas valve, and controls all appear clean and undamaged. Some surface rust is visible on the copper gas supply pipe and the manifold header, consistent with storage. The unit ships on its original pallet.
