The Marathon KERA180BRE is a diesel-fired, oil-jacketed melting kettle engineered for high-production crack filling with hot poured rubberized crack sealant. As the entry point in Marathon’s KERA crack fill trailer lineup, the 180-gallon model is built for crack sealing contractors, property maintenance crews, and smaller municipal fleets that want professional throughput without the size, weight, or tow requirements of a larger unit.

What sets this crack sealing trailer apart is that it is a complete applicator on its own. The electrically heated hose and wand system heats, melts, and applies rubberized crack sealant directly from the machine, so crews are not managing a separate pour pot or transfer step. That single-machine workflow keeps sealing operations fast and reduces the equipment a contractor has to buy, tow, and maintain.

Heat management is handled by a Digital Automatic Temperature Control System that regulates both the heat transfer oil and the sealant itself. Combined with full ceramic fibre insulation and the oil-jacketed vat design, the KERA180BRE applies indirect heat evenly around the material, which helps protect sealant integrity and avoid the scorching common with direct-fire units. A 120V 1,500W overnight heater keeps the machine warm between shifts to cut daily start-up time, while a recirculation port speeds morning warm-up and keeps material blended.

The unit is powered by a 23 hp liquid-cooled, electric-start Kohler diesel engine and a single 340,000 BTU diesel burner. An onboard 3,000W generator heats the delivery hose and doubles as a 120 VAC power source on the job site. Reverse-loading, anti-splash doors on the curbside make loading blocks of sealant safer, and an operator alert horn plus on-demand pumping system round out the production-focused feature set.

Construction is heavy duty throughout: minimum 10-gauge steel, fully welded, built on heavy 6-inch channel and gusseted for strength and safety. The KERA180BRE rides on a tandem axle rated for 10,400 lbs (4,717 kg) with four 225/75/R15 tires, making it the easiest KERA model to tow and position for crews working residential streets, commercial parking lots, trails, and municipal maintenance routes.

For Canadian contractors, the 180-gallon size is a practical fit for shorter sealing seasons and mixed workloads where a smaller, nimble crack trailer sees better utilization than a highway-scale machine.
