Chemical-free weed control for sensitive places
A precise, modular hot-air system for schools, historic buildings, estates, councils and contractors that need professional weed control without liquid herbicide residues or a water supply.
A professional alternative to routine spraying
Precise heat where you need it, with no chemical drift
Ripagreen uses a high-velocity flow of hot air to deliver a brief thermal shock. The modular range prioritises speed, control and operator mobility across sensitive, public-facing and difficult-access sites.
Controlled application
A short, rigid treatment zone helps the operator target joints, kerbs and edges without the drift associated with liquid spraying.
Works across varied sites
Choose backpack, trolley or vehicle-supported configurations to move between steps, courtyards, paths, estates and municipal routes.
No water logistics
There is no water tank to fill, heat or transport. The system uses ambient air with a controlled propane or biopropane supply.
Suitable for visible places
No chemical residue or spray marker is left behind, making the method attractive for high-presentation and public-facing environments.
Built around real maintenance environments
One system, four demanding audiences
The right configuration depends on access, surface type, public occupancy, route length and weed maturity. These sector journeys explain how Ripagreen can fit into the wider maintenance programme.

Thermal shock—not prolonged burning
The operator briefly heats the plant so its cells are damaged and photosynthesis stops. Good timing and repeat frequency matter more than visibly scorching the weed.
Start with young growth
Treat seedlings and fresh annual growth early, before deep root reserves and woody stems make control more difficult.
Apply a brief, controlled pass
Keep the correct operating distance and look for a leaf response rather than blackening or charring the plant.
Repeat and integrate
Use planned follow-up passes and combine hot air with detritus removal, prevention or another method where established perennials demand it.

Responsible professional use
Plan the heat, the public and the surface together
Ripagreen is a professional LPG-powered heat tool. Its safety features support responsible operation, but they do not replace training, supervision or a site-specific assessment.
- Use trained operators and follow the current manufacturer instructions.
- Inspect and clear dry detritus or other combustible material before treatment.
- Establish an exclusion zone and schedule public-facing work appropriately.
- Avoid operation where hot, dry or windy conditions create an unacceptable fire risk.
- Carry suitable fire-control equipment where required by the risk assessment.
- Store, transport and connect LPG cylinders in accordance with current guidance.
- Test representative heritage or heat-sensitive surfaces before wider use.

Before you introduce hot-air treatment
These answers provide a starting point. The product manual, operator training and site risk assessment remain the controlling documents for use.
Do the weeds need to be burnt or charred?
No. Effective thermal treatment is a brief heat shock rather than prolonged burning. The aim is to damage the plant cells and stop photosynthesis; blackening the plant wastes time and energy and may increase surface or fire risk.
Can Ripagreen be used in wet weather?
The manufacturer states that its short, rigid flame and pulsed hot-air system can remain effective in rain and light breezes. Operation must still follow the site risk assessment, manufacturer instructions and local conditions. Avoid use where dry or combustible material creates an unacceptable fire risk.
Is it suitable for schools and public sites?
It can be a useful chemical-free option for paths, edges, courtyards and play-area surroundings when used by trained operators with an exclusion zone and suitable scheduling. Work should be planned away from pupils, visitors and other members of the public.
What types of weeds respond best?
Young annual weeds and fresh growth are the strongest fit. Established woody or deep-rooted perennial weeds may require repeated passes or a different method. Ripagreen is most effective as one tool within an Integrated Weed Management programme.
Which gas should be used?
Use propane or compatible biopropane in the gaseous phase, in a cylinder size appropriate to the chosen kit. Follow the current Ripagreen instructions for regulators, hoses, storage, transport and cylinder connection.
Which kit should we choose?
Choose Mobility for difficult access, Easy for comfortable linear work, Easy+ for mixed sites, Autonomy for vehicle-supported routes, Autonomy+ for longer shifts and Autonomy Duo for simultaneous two-operator work. A demonstration is the best way to confirm the right configuration.
