UKB 655E

weed control machines

Put the turbo on the weed control

The TURBO blower ensures very high combustion efficiency, as well as a high turbulence and air speed, which provides an efficient heat transfer on the weeds and thus a fast blanching, regardless of which surfaces need to be freed of weeds.

A treatment with the ZACHO high-temperature hot air system shows a convincing result after just a few days.

Our weed blanching machines are commonly called UKBs.

This method of weed control is very special as it operates at up to 800 degrees, hot air that gives you a higher operating speed.

Its powerful fan allows the hot air to get well under the leaves and gives an effective result, while ensuring the much greater safety against fire danger.

We have developed UKBs that are self-propelled and for mounting on tool carriers or other types of machines. We have developed both UKBs that are self-propelled and for mounting on tool carriers or other types of machines.

With a UKB you get a product that is built to last for many years, we have machines that after 18 years still run without changing the fuel box and guns.

At the same time, you completely save on the use of chemicals to get rid of the weeds.

Our UKBs last unbelievably long. We do not know exactly how long, but we have machines that have been running for 18 years and are still running.

On the NEW ZACHO UKB 655E are we replacing the internal combustion 

engine with an electric fan and battery

It's good for you and the environment.

We have both developed UKBs, which are self-driving, 

and we have developed types that

tool carriers or other types of machinery are fitted.

The machine is used for blanching weeds on fortified areas, including substrates of asphalt, concrete, gravel and 

other forms of heat-resistant coating.

The machine is used along kerbs, on pavements, paths, cycle paths, walking areas,

as well as pouring facilities and around signs.

The machine must not be used in closed rooms.


UKB 655E is based on a high-temperature hot air system. The air is sucked in through the blower housing mounted on the engine and is led via blower hose to the gun's combustion chamber, where the ignited gas is mixed with a large amount of air, which ensures a very high combustion efficiency. Since the combustion chamber is located in the upper part of the gun, only the heated air is blown out through the gun and into the heat shield, where due to the amount of air it is pushed out in front of the machine, thereby heating the area in front, as a result of this pre-heating, it ensures a high and efficient work speed, when the weeds are "blanchered" in seconds

The construction of the cannon ensures that there is no danger of burning when touched or of setting fire when the machine is in use

Effective around signs, lampposts and benches etc. due to the hot air fan in front of the machine.

Safe and simple operation with "Quick on/off function".

Electronic continuous ignition (i.e. the ignition runs continuously during operation) and automatic gas cut-off when stopped. No flammable gas/air mixture outside the equipment due to the air-based system with large excess air.

With the Quick on/off function, the equipment is particularly suitable for "interval treatment", which saves a lot of gas.
