The principle of thermal weed remediation is based on a basic biochemical rule: Most proteins denature from a temperature of about 42 ° C. This means that the proteins can change, break up and no longer fulfill their functions. The heat required for this is generated by the combustion of gas or oil and converted in different ways:
Directly as a flame or indirectly via heat radiation or as hot water or steam. Of this, hot water is the only chemical method that also reaches the roots.
Even if the roots are not completely destroyed immediately, the weed is weakened with every hot water application. If you perform the application regularly from the outset, the regrowth will be inhibited and the frequency of use will decrease significantly in the second year. As a rule of thumb, 3 to 4 treatments a year are enough.
Advantages against other procedures:
√ Low environmental impact
√ Plants and root are weakened and destroyed, even the seed
√ Low noise
√ Suitable for all surfaces, also suitable for critical and poorly accessible areas
√ High efficiency
√ Up to 4 applications in the first year, decreasing in the following year
