Electric Docked Trailer Heater (DTH)
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.
Transforming Operations & Employee Safety in Minutes
This game-changing solution transforms dock operations by:
- Warming trailers in as little as seven minutes significantly reducing downtime
- Eliminating costly delays and boosting productivity across the facility
- Reducing facility heating loads by targeting only the space that needs it
- Improving safety and morale by minimizing cold exposure
- Supporting OSHA compliance and lowering the risk of cold-related injuries
- Absorbing incidental forklift contact without damage
- Offering year-round versatility with a fan-only mode for warmer months
Installation and Operation Made Easy
The DTH is delivered pre-assembled on a dual-purpose crate/lift. The included mounting kit makes setup fast and easy. After installation, choose between heat mode, fan mode, or off with the press of a single button.
