Revolutionizing Cold-Weather Dock Operations

Loading and unloading docked trailers in cold environments can be a difficult task. Cold weather often delays operations, reduces worker comfort, and impacts safety.

The Reznor® Docked Trailer Heater (DTH) sets a new standard for dock efficiency, quickly turning cold trailers into warm, workable environments in under seven minutes. Installed directly at the dock door, it stays clear of daily operations while delivering a powerful stream of heated air - no need for in-trailer units or extended warm-up times.

With a built-in fan mode for warmer months, the DTH Docked Trailer Heater supports year-round comfort, enhances employee satisfaction, and helps cut down on energy use and delays.

How the Docked Trailer Heater Works

High-velocity fans and premium heating elements inject warm air into the trailer’s top, pushing cold air out the bottom. In just minutes, the trailer reaches warehouse-like temperatures enhancing comfort and keeping your operation moving.
