HOAF thermHIT® 75M/100M/125M
Chapter 4 - Description
4.2 Use of the
HOAF thermHIT® 75M/100M/125M
4.2.1 Weed killing method
The use of the
HOAF thermHIT® 75M/100M/125M
is based on the Infraplus®
System, developed by
HOAF Infrared Technology
. This system makes use of
infrared radiation heat in combination with more focused flame heat and a hot air
stream. The heat for this Infraplus® System is generated by burners that were
specially developed for this purpose. The principle of the Infraplus® System is
comparable to the effect of sunshine. After all, sunshine also consists to an
important extent of infrared radiation.
By exposing the weed seed to intensive infrared radiation for a short moment, the
proteins coagulate. This will cause the walls of the moisture cells to expand,
which will make the plants wither. This process is reinforced by the powerful hot
air stream coming from the burner. Thanks to the combination of infrared radiation
and hot air, the natural withering process is achieved in a very short time. In
addition to this, the Infraplus® System also removes the germinating power of
the seeds in the soil. This slows down regrowth.
Even though the infrared radiation barely penetrates the soil, and cannot cause
soil damage, the root system of the weeds is exhausted after a few treatments,
and will die. The withering process of the root system means regrowth is slowed
down further and further, and the period between two treatments will increase.
