Eco Weedkiller Pro 40H

Eco Weedkiller PRO40H is the most powerful and versatile model in the product family. It utilizes the base machine’s hydraulics. In addition to weed and invasive species control, the PRO40H is well suited for a wide range of property maintenance tasks, from cleaning and thawing to drain unblocking.

For professionals
Deep Cleaning Deep cleaning is based on ozonated water, which is produced by an ozonation unit available as an optional accessory for the device. The method is particularly suitable for the effective and hygienic cleaning of playgrounds, outdoor furniture, and waste collection shelters.
Drain opening A special nozzle is used for opening and thawing drains, clearing blockages with high-pressure water. The nozzle moves forward inside the pipe using water pressure, penetrates the blockage, and breaks it down while flushing it away.
Invasive plant control In the control of invasive species, the same 100-degree hot water technology is used, but the treatment focuses in particular on an effect that penetrates deep into the root system.
Melting Eco Weedkiller Pro is also well suited for ice melting in winter conditions. Hot water can be used for a wide range of property-related thawing and de-icing needs.
Pressure Washing Eco Weedkiller Pro also functions as a professional pressure washer. You can choose either cold or hot water for high-pressure cleaning.
Weed control Thanks to the technology used in Eco Weedkiller systems, hot water is effectively absorbed into the ground, transferred to the root system, and destroys the plant’s cellular structure. As a result, the weed dies down to the roots, and regrowth is significantly reduced.

Deep cleaning

Deep cleaning is based on ozonated water, which is produced by an ozonation unit available as an optional accessory for the device. The method is particularly suitable for the effective and hygienic cleaning of playgrounds, outdoor furniture, and waste collection shelters.

Drain opening

A special nozzle is used for opening and thawing drains, clearing blockages with high-pressure water. The nozzle moves forward inside the pipe using water pressure, penetrates the blockage, and breaks it down while flushing it away.

Invasive plant control

In the control of invasive species, the same 100-degree hot water technology is used, but the treatment focuses in particular on an effect that penetrates deep into the root system.

Melting

Eco Weedkiller Pro is also well suited for ice melting in winter conditions. Hot water can be used for a wide range of property-related thawing and de-icing needs.

Pressure Washing

Eco Weedkiller Pro also functions as a professional pressure washer. You can choose either cold or hot water for high-pressure cleaning.

Weed control

Thanks to the technology used in Eco Weedkiller systems, hot water is effectively absorbed into the ground, transferred to the root system, and destroys the plant’s cellular structure. As a result, the weed dies down to the roots, and regrowth is significantly reduced.

Watering

Eco Weedkiller PRO units are also suitable for efficient watering. The unit enables controlled and even water distribution to planting areas, trees, shrubs, green areas, and nurseries. The large water tank and powerful pump technology ensure sufficient water supply even at sites where no fixed water connection is available.

Root cause

Our devices destroy weeds and invasive species down to the roots with hot water – completely without pesticides. Hot water is an unfamiliar threat to plants, one they have not developed protection against. Eco Weedkiller devices always produce 100 °C water, and thanks to their technology, the water remains hot until it reaches the root, destroying it with the thermal energy it carries.

How it works

1

Fill the device with normal tap water

2

Wait for the water to heat up to 100°C

3

Apply hot water to unwanted plants

4

Remove dead plants if needed

5

Repeat 3–4 times a year to destroy root systems

Heavy-duty made easy

In the PRO40H unit, water is heated by two industrial burners (combined output 256 kW) and pressurised using hydraulics. Operating at an efficiency of over 95%, the system produces 40 litres of 100 °C water per minute. This is sufficient for effective and cost-efficient control of even the most challenging invasive species. The unit is powerful yet easy to use. Commissioning requires no calibration or adjustments—the operator can focus solely on the treatment. PRO40H is built with durable components, and spare parts and upgrade options are readily available.

Hydraulic power enhances performance

The unit is connected to the hydraulics of a property maintenance machine, tractor, or truck, providing an efficient and environmentally friendly power source. When an external water tank is connected, the unit can transport large volumes of water. This improves efficiency and reduces time spent fetching water. Almost all existing tanks are suitable for use. The best treatment results are achieved by applying the water manually, although clearly defined areas can also be treated mechanically. Optional accessories include front and rear spreading units as well as various hose and nozzle options.

A true all-rounder for property maintenance

In addition to weed control, the unit is suitable for pressure washing, ice thawing, drain unblocking, and graffiti removal. An optional ozone water generator is available for odour removal and deep cleaning. PRO40H is a comprehensive solution for property maintenance and municipal service needs.

What factors influence cost-effectiveness in invasive plant and weed control?

  • Water management must be planned according to the water demand of the site. Costs increase significantly if water has to be transported using a small tank.
  • The production capacity of boiling water per minute/hour is important. Heating water is relatively inexpensive compared to labour costs.
  • The correct dosage destroys weeds down to the roots, delaying the need for the next treatment. The biggest mistake is trying to save water.
  • Regular and systematic control.The amount of plant biomass, especially with invasive species, has a significant impact on costsTimely control measures.
  • Regularly combining different methods in area maintenance ensures cost-effectiveness without the use of harmful chemicals.

Why is it beneficial to combine different methods in invasive and weed control?
