Reznor DTH-18 Docked Trailer Electric Unit Heater - 18kW / 62,000 BTU, 480V 3 Phase

The Reznor DTH trailer unit heater is a first-of-its-kind, purpose-built solution for docked trailers. With a fast 7-minute warm-up, DTH improves working conditions, enhances loading-dock safety, and boosts productivity — ideal for warehouses, logistics centers, and fleet operators.

The DTH isn’t limited to a single season. In spring and fall, when only minimal heating is needed, its fan-only mode gently circulates warehouse air into the trailer to provide light warming. In summer, the DTH delivers a cooling effect by injecting cooler dock air into trailers—where interior temperatures can soar up to 160°F. This year-round versatility speeds up loading and unloading, boosts throughput, reduces worker discomfort and heat stress, enhances safety, and helps retain staff by creating a more comfortable working environment.
