Our W-JET Weed Control System has the following advantages:

Our system improves effectiveness by treating all and any part of each plant, by a 450°C hot jet-exhaust and steam treating the plants in full to the ground.

The system is "fireproof", as it has no oxygen or open flames. In fact, it can pass over dry paper without causing any fire!

The consumption per hour is 15 kg fuel and 30 kg water, with a capacity of 3500 - 4500 m². Consumption converted to hectares will be 45 kg fuel and 90 kg water (in rain or moist, no extra water needed) per hectare.

The first photo above was taken right after a weed test and it did look as if we just washed the grass! Two days later we made the photo below and it shows the result after one treatment!


The 55 kg W-JET M1 jet module can deliver up to 105 m³/min at 620°C when used for road drying. In WEED Control set-up we only need power slightly above idle, then producing app 16 m³ hot exhaust per min., and with the patented WATER INJECTOR System the exhaust temperature will go down to app 450°C now in a mix of hot jet exhaust, steam and water spray, circulating under the heatshield with a tremendously greater heat transfer capability. The JET turbine noise is hereby lowered to a minimum, as well as fuel consume is reduced to 15 l/h, water consume (in rain or wet conditions no need) on a dry day is up to 30 l/h. Treat capacity is app 3500 to 4500 m²/h.

Comparing our system to LPG Gas Weed-control:

Conclusion in the official report LPG Gas Weed-control report "Weed control on roads without pesticides"  (ISBN 87-7903-243-5)

Photo to the right shows a test field where there was performed 10 treatments at two-week intervals with dosages from 40 kg gas/ha/treatment in the left box, 80 kg in the middle and 120 kg to right.

There was so 40 kg difference between each stripe, but there was significant differ-rence in the effect between 40 and 80 kg gas/ha than between 80 and 120 kg gas/ha.

It was no additional effect by increasing to 120 kg gas/ha. It was so concluded that the pesticide-free methods require ongoing effort because they only remove weeds here and now, not preventive.

The W-JET ”WEED” System:

We offer the WEED system build up on several self-propelled machines, small walk behind unit or small tractors with or without air-conditioned cabin. Type WAT1 to WAT4 can run single or double W-JET M1 Modules, and fuel and water for several hours, excellent for working 4 -6 hours.
