High Output Double Linear Radiant Heater for Large Industrial Warehouses

The Powrmatic PVDL20LS is a high-capacity double linear radiant tube heater designed to provide powerful infrared heating performance across large industrial buildings such as warehouses, factories and distribution centres. Delivering a heat input of 44 kW, this model uses vacuum burner technology to create consistent radiant tube temperatures along the emitter length, ensuring uniform heat distribution throughout the occupied space.

Unlike traditional warm-air heating systems that heat the air volume within a building, radiant tube heaters emit infrared heat energy directly to floors, equipment and people within the working zone. This dramatically reduces heat losses caused by air stratification in high-roof buildings where warm air would normally rise toward the ceiling.

The double linear tube configuration effectively doubles the radiant emitter surface area compared with a single linear heater, allowing greater heat coverage while maintaining efficient operation. This configuration is particularly suited to wide warehouse bays, manufacturing areas and logistics buildings where high heat demand exists over large floor areas.

The heater incorporates two-stage high/low burner technology, allowing rapid heat-up on high fire and energy-efficient steady operation on low fire once the desired temperature has been reached. Automatic control is typically achieved using the MC200 energy-saving controller with black-bulb radiant sensor, ensuring accurate temperature control within the occupied zone.

With robust industrial construction and high-efficiency aluminium reflectors directing radiant energy downward, the PVDL20LS provides an effective heating solution for demanding commercial environments where reliable performance and energy efficiency are essential.
