              The most effective agricultural weed burners on the market

              How can our system reduce gas consumption by up to 40 percent compared to other weed burners? This is achieved by ensuring an optimised gas and air mix during combustion and at the same time protecting the combustion against the surrounding wind. Hereby the heat from the combustion is fully utilised for weed control, which results in high efficiency. This makes our system unique.

              All ENVO-DAN’s agricultural models are built in cooperation with the customer and according to the customer’s needs, so we make sure that the burner exactly fits the crops it is working in. We have a large range of models for both front and rear mounting.

              In recent years, we developed a new concept that emerged from customer demands. We constructed an in-row burner, a model we call E-THERM SELEKT. During burning this machine removes the weeds in the row and between the rows, without damaging the culture plants. This working principle differs from traditional weed burners.

              Try our machines – reduce your costs and manage the weed control in your organic production in a better way! With the investment in an agricultural weed burner from ENVO-DAN, your weed burning will be an effective organic and sustainable solution.

              When you contact us, we have a thorough conversation about your needs as an organic farmer with special challenges in the production of potatoes, carrots, onions, corn, and other organic crops. All ENVO-DAN’s agricultural models are built to make farming life easier, and we manufacture the burner to fit the crops it will be working in.

              About E-Therm

              E-Therm is a weed burner designed for efficient pre-emergence weed control. E-Therm is one of the market’s most energy-efficient weed burners with documentation on savings on gas consumption of up to 40 percent. The documentation is conducted by the Faculty of Agricultural Sciences in Flakkebjerg, Denmark.

              All ENVO-DAN’s models are equipped with an air supply, which creates overpressure under the shield. This makes you able to operate at wind speeds up to 12 metres per second, and it does not have any effect on the process of weed burning.

              E-Therm weed burners can be delivered in all widths from 1.5 to 9.2 metres. Depending on the width, E-Therm is delivered as a hydraulic foldable system for road transport at widths where this is necessary.

              E-Therm 1500 – 1850

              This model is available in widths ranging from 1.5 metres to 1.85 metres and is a very versatile burner that fits the row distance from 50 to 75 centimetres.

              E-Therm 3200

              E-Therm 3200 is a good choice for 50 and 75 cm row distance. The double-width compared to E-Therm 1600 doubles the capacity. E-Therm 3200 can in addition also be mounted in the front, which ensures a better view and a good working environment.

              E-Therm 5300 – 6600

              This model has a huge capacity and a width of up to 6.6 metres. At the same time, the efficiency is high due to ENVO-DAN´s optimization of air supply and an insulated shield, which ensures consistent treatment of weeds over the entire width, no matter wind direction and speed.

              E-Therm 9200

              E-Therm 9200 from ENVO-DAN is one of the world’s largest weed burners. A larger gas tank ensures a larger action radius, so E-Therm 9200 manages 33 ha on one tank full.

              The middle part is front-mounted, while the wings are mounted on the trailer with a gas tank. It gives good stability on the wing part due to the trailer’s weight and construction. The wings can be folded up by hydraulic for road transportation.

              About E-Therm Selekt

              The E-Therm Selekt is an in-row weed burner designed in such a way that efficient burning of post-emerging crops can be achieved. This machine has burner hoods in front, where leaf-lifting guides are mounted. These collect the leaves and keep them upright as far as possible to ensure that the heat can enter the row, exactly where the germinating weeds have to be controlled.

              The in-row weed burner also sends heat underneath the sides. In this way, thermal weed control takes place in the rows of crops. At the same time, the weed control in the rows provides thermal control for young weeds. The idea of in-row burning is to protect the crop while no new weeds are awakened and there is no danger of root damage, as is the case with the hoe. Root damage often results in stunted crop growth.

              Organic corn fields before and after weed burning

              Organic food production is about creating a sustainable agriculture and food system where special consideration is given to the environment, nature, and animal welfare.

              Many factors come into play before the success of your harvest and your earnings can be determined. Weed control is one of them. An ENVO-DAN agricultural weed burner can be the solution to one of your challenges: fast-growing weeds that take over where your organic onions, potatoes, carrots or corn should be growing.

              See pictures below of organic farming with corn fields, taking advantage of efficient weed burning.
