Why organisations choose HOAF

One thermal method, three practical ways to deploy it.

The best starting point depends on access, daily route length, available carrier equipment and how much operator effort the programme can support.

Targeted thermal treatment

Infrared radiation and hot air are directed at unwanted vegetation without applying a chemical spray.

Works across site types

Choose a format for narrow paths, formal grounds, public spaces, estates or larger municipal routes.

Start small and scale

An unpowered pedestrian machine offers a lower-investment route into thermal weed management.

Use existing carriers

Powered and mounted systems can integrate weed control into established Kersten or tractor-based maintenance fleets.

How the Infra Plus process works

Heat the plant tissue—do not try to burn it away.

The HOAF system combines infrared radiation with hot air. The objective is to transfer enough thermal energy to disrupt the plant’s cells, after which the vegetation wilts and dies back.

1

Prepare the route

Remove heavy litter, dry combustible material and excessive detritus so the treatment can reach the target safely and consistently.

2

Apply controlled heat

Pass the treatment head over the vegetation long enough to heat the tissue; visible charring is not the operating objective.

3

Plan repeat visits

Return according to species, growth stage and regrowth, combining thermal treatment with prevention and surface cleaning.

Best results come from programme design. Young growth, route preparation, treatment timing and follow-up frequency can matter as much as machine size.

Responsible thermal operation

High heat requires disciplined site preparation.

HOAF equipment should be used by trained operators working to the current manual and a task-specific assessment covering people, surfaces, fuel, weather and combustible material.

  • Remove or control dry litter, leaves and other combustible material before treatment.
  • Maintain an exclusion zone around visitors, pupils, residents, vehicles and vulnerable planting.
  • Inspect the machine, fuel system and safety devices before each working period.
  • Test unfamiliar or heat-sensitive surfaces before treating a wider area.
  • Stop when wind, drought, access or surrounding material makes controlled thermal work unsuitable.

Frequently asked questions

What buyers usually need to decide first.

How does the HOAF Infra Plus system affect weeds?+

The system combines infrared radiation with hot air. Heating the vegetation to around 80°C disrupts proteins and moisture cells, causing the plant to wilt and die back.

Which HOAF range should I start with?+

Start with a push-operated machine for narrow access and shorter routes, a powered Kersten attachment for regular pedestrian work, or a tractor and vehicle-mounted system for longer and wider programmes.

Does the weed need to be visibly burned?+

No. The operating objective is controlled heat transfer into the plant tissue, not charring or burning the vegetation away.

Will one treatment permanently remove every weed?+

No thermal method should be selected on that assumption. Results vary by species, growth stage, stored root reserves, route preparation and repeat-treatment timing.

Can HOAF be used around the public?+

Work must be planned around site occupancy, with trained operators, suitable exclusion controls and a risk assessment for heat, fuel, surfaces, weather and combustible material.

Why arrange a demonstration before choosing a machine?+

A measured demonstration reveals real access constraints, treatment pace, carrier suitability and the difference between theoretical site area and the route an operator must actually complete.

Choose the HOAF format around your real route.

Share the surfaces, access points, daily route, current method and available carrier equipment. Kersten can then recommend the most useful machine to demonstrate on site.

Frequently Asked Questions

The Hoaf Infra Plus System employs infrared radiation combined with hot air for effective weed control. This process exposes unwanted vegetation to heat, causing proteins in the weeds to congeal and moisture cells to burst at approximately 80°C. As a result, the vegetation begins to wilt and eventually dies, providing a pesticide-free solution for various public and private spaces.

Hoaf Thermal Weed Control products offer several benefits, including pesticide-free weed removal, making them ideal for public spaces, footpaths, carparks, and homes. Their design allows for excellent access into tight areas while also being efficient for covering sizable areas. Additionally, these products can be used in wet conditions, reducing weather dependency for weed killing tasks. The low hood design facilitates access under obstacles like park benches and picnic tables.

Yes, Hoaf Weed Burners are designed to be used in wet conditions. The product's reliance on heat for weed control means that its effectiveness is not compromised by moisture. This feature allows users to perform weed killing tasks with less dependency on dry weather, ensuring more consistent and flexible operation schedules for maintaining public and private areas.

Hoaf Thermal Weed Control products are available in two main forms for pedestrian use. The first type includes unpowered push-along burners, offering a straightforward solution for weed management. The second type consists of powered attachments specifically designed for compatibility with K-Series Kersten machines and the UBS Easy 13, providing integrated solutions for more extensive applications.

The Hoaf Infra Plus System eliminates weeds by exposing them to a combination of infrared radiation and hot air. This heat treatment causes the proteins within the weeds to congeal and the moisture cells to burst open once they reach a temperature of approximately 80°C. This cellular disruption leads to the wilting and eventual death of the vegetation, providing an efficient and environmentally friendly method of weed control.
