KPL-WEED Weedkiller Unit

The DYNASET KPL-WEED Weedkiller Unit converts the hydraulic power of a mobile machine, vehicle, or vessel into a hot water-based solution for effective, chemical-free weed control. 

The KPL-WEED Weedkiller Unit offers a powerful, chemical-free solution for weed control using only hot water to eliminate weeds from large areas efficiently. Equipped with a water heating unit that heats water to 102°C (216°F), this unit effectively targets weeds all the way to the roots, providing complete removal. Designed for versatility, it can be used on streets, parking lots, sidewalks, pathways, pavements, and curbs. With options of both a weed control pipe and a hand-held spray gun, it’s easy to cover large areas while precisely targeting specific spots.

How Does the Weedkiller Unit Work?

The DYNASET Hydraulic High Pressure water pump on the weedkiller unit uses a carrier machine’s or vehicle’s hydraulic system as its power source to produce water flow for weed control. 

  1. Hydraulic oil flow is directed to the water pump through the pressure line.
  2. The hydraulic high-pressure water pump converts the hydraulic oil flow and pressure into water flow. 
  3. The hydraulic oil is then returned to the carrier machine’s hydraulic oil tank through the return line. 
  4. The water is heated by the water heating unit up to 102°C (216°F). 
  5. The heated water is directed through the pump to either the weed control pipe or roller, which applies 98°C (208°F) water droplets onto the weed surface. 
  6. The hot 98°C water penetrates down to the plant roots for complete elimination.
