HW, Dual Axel 7000 LBS Trailer, 3,000 PSI, 8.0 GPM Gas Hot Water Pressure Washer, HW3024HG12V-TD7

When a job calls for hot water, mobility, and enough onboard capacity to run all day without a refill, the HW3024HG12V-TD7 is built to answer. This industrial series trailer system pairs a Honda GX690 engine with a General TSF2021 triplex pump and a diesel fired heating system, all mounted on a dual axle trailer designed for real jobsite use. For fleet washing operations, grease and oil removal, and heavy duty degreasing work where cold water alone will not cut it, this unit is set up to keep working.

Power That Is Built to Last

At the core of the HW3024HG12V-TD7 is a Honda GX690 engine, an air cooled, four stroke OHV design displacing 688 cc. Electric start with a 55 AH marine battery included means no pull cord, no wasted time, and no missed starts on a cold morning. The engine runs on 86 octane fuel with up to 10% ethanol and draws from a 14.4 gallon fuel tank, giving operators long runtime between fill ups.

Power reaches the pump through a belt drive system, a deliberate design choice that lowers heat, vibration, and RPM at the pump itself. The result is longer pump life and fewer service calls over the life of the unit, which matters as much to a fleet manager tracking uptime as it does to a technician working the truck.

Industrial Grade Pumping and Heating

The General TSF2021 triplex pump is built for continuous duty. Its reinforced body, forged brass manifold, solid ceramic plungers, stainless steel check valves, and thermal relief valve are the same features found on pumps designed to run all shift, every shift. An external unloader adds superior cooling and versatility, extending pump life further while giving operators more control over pressure and flow during use. An adjustable injector soap system rounds out the pump package for operators who need to apply detergent as part of the cleaning process.

Hot water comes from a heating coil ignited by a 12V Beckett burner and fueled by diesel or kerosene, with an adjustable thermostat that reaches up to 93°C, 199°F. That kind of heat output is what breaks down grease, oil, and heavy soil that cold water pressure washing simply cannot touch. Oil drain hoses on both the engine and the pump make routine maintenance faster and cleaner, cutting down on the mess and downtime that come with standard oil changes in the field.

A Trailer Built for the Work

The HW3024HG12V-TD7 rides on a dual axle, 7,000 lb trailer with electric front axle brakes, DOT approved lights, and a swing up jack with a heavy duty coupler. It is finished in black automotive paint for a clean, professional look on the road and on the jobsite. This is a trailer built to be towed, parked, and put to work day after day, not a temporary setup.

Water capacity is where this system really separates itself for high volume work. A 325 gallon algae proof water storage tank keeps operators supplied through long jobs, supported by a PVC 3-way ball valve, an in line water filter, and a Hudson float valve to manage fill and flow. A 26 gallon chemical tank sits alongside it, keeping detergent onboard and ready without a separate trip.

For hose management, two 150' Centurion hose reels are mounted on a stacker kit for organized onboard storage, keeping hose runs tangle free and ready to deploy. A 100' Centurion garden hose handles the water inlet connection, giving operators the reach they need to set up on a wide range of sites.

Ready to Connect and Go

Every HW3024HG12V-TD7 comes equipped with the accessories operators actually use in the field. That includes a 100' x 3/8" hose, a 47" insulated gun wand, and a full nozzle set covering 0°, 15°, 25°, and 40° patterns plus a soaper nozzle, all built around quick connect fittings for fast tool changes between tasks.

Backed by a Warranty That Reflects How It Is Built

This system carries a 3 year warranty on the engine, a 5 year warranty on the pump, a 3 year warranty on the burner, and a lifetime warranty on the heating coil. That kind of coverage on the pump and coil signals confidence in the core components doing the heaviest work, and it gives dealers and end users a warranty structure that matches how the unit is actually used.

Built in the USA, Ready for the Field

The HW3024HG12V-TD7 is made in Decaturville, Tennessee. It is not for sale in California.

Who This Unit Is Built For

This is a trailer system for operators who need hot water performance without sacrificing mobility. Fleet wash businesses cleaning trucks and heavy equipment, contractors handling degreasing and heavy soil removal, and any operation that needs to move from site to site with a self contained water and chemical supply will find this configuration built around their actual workflow. The combination of a 325 gallon tank, dual hose reels, and a heavy duty trailer chassis means less time managing logistics and more time getting the job done.

For dealers, the HW3024HG12V-TD7 represents the kind of complete, ready to deploy package that reduces the back and forth of building a custom setup. The engine, pump, burner, trailer, and accessories are matched and warrantied as a system, which simplifies the sale and the support conversation on the back end.
