The Mi-T-M HMT-4004-0MGH is a DOT-approved hot water mini trailer producing 4000 PSI at 3.7 GPM, powered by a 389cc Honda GX390 OHV engine and a General pump. The 12V Beckett burner delivers 343,000 BTU/hr with a 140°F (60°C) temperature rise above ambient. The reinforced powder-coated steel trailer includes a 10-gallon burner fuel tank, locking storage, 8-inch tires, and standard 2-inch ball hitch towing.
Pressure, Heating, and Engine
- Pressure: 4000 PSI at 3.7 GPM — high-pressure output for mobile fleet washing, heavy equipment cleaning, and construction site degreasing.
- Temperature rise: 140°F above ambient — hot water cleaning advantage for grease, oil, and biological contamination that cold water cannot fully address.
- Engine: 389cc Honda GX390 OHV — Honda's dependable commercial engine with remote start, choke, and 12V electric start (battery not included).
- Pump: General — adjustable pressure unloader, forged brass manifold, and thermal relief valve for sustained high-pressure performance.
- Burner: 12V Beckett, 343,000 BTU/hr — operates on No.1/No.2 fuel oil, diesel, or kerosene; 10.0-gallon tank at 2.45 gph consumption.
- Burner coil: ½" Schedule 80 pipe with 4-pancake heat exchanger — commercial-grade heating components rated for sustained high-temperature pressure washing.
DOT-Compliant Trailer Design
The HMT-4004-0MGH trailer is DOT approved for highway towing with a removable safety flag and 1000-lb axle. It includes 2.875 cu.ft. of locking rear storage for accessories, protective gear, and fuel containers. The caster brake stabilizes the unit during operation. Optional accessories (TX-0010 adjustable coupler hitch and TX-0020 high-pressure hose reel) must be specified at time of order.
