The protection you've waited decades for.

For decades, fruit growers and winegrowers have faced hailstorms that destroy entire yields in just a few minutes. Our expert team developed and manufactured the first device of this kind in Serbia back in 2015.

The PGT-A80 is carefully designed for preventive action — to effectively suppress the formation of hail and prevent damage to crops in fruit growing, viticulture and vegetable growing.

A shock wave,
straight into the cloud.

The effect is based on generating an ionizing acoustic shock wave. Traveling toward the upper layers of the atmosphere, the wave causes turbulence that disrupts the joining of droplets and the formation of ice nuclei — so hail does not form at all. The action is preventive.

The waves are produced by combusting a mixture of acetylene and air in a special chamber, emitted every 4–7 seconds, and act on the front of the incoming cumulonimbus.

One circle.
Eighty hectares.

The device protects an area 1 km in diameter — a circle with a 500 m radius, equal to up to 80 hectares. The wave travels at the speed of sound (≈ 330 m/s); full effect is achieved by activating 20–30 minutes before the storm.

From the forecast to clear skies.

Radar flags the hail cloud over the location, and the device activates 20–30 minutes earlier — preventively stopping hail from forming in the cloud.

Engineering in every detail.

Mobile unit

Delivered in a protective container; transported by truck, trailer or tractor. The location can be changed as needed.

Remote monitoring

Android/iOS app, severe-weather notifications, radar imagery and live status. GSM/GPRS, SMS and LTE modules.

Non-polluting

Acetylene burns down to CO₂ and water vapor — no smoke or soot. An environmentally friendly solution.

Controlled noise

Shock wave directed upward; ≈ 90 dB at 50 m. Acceptable for both rural and urban environments.

Fast assembly

On-site setup in one working day at most. Removable wheels and frame.

Networking

Several neighboring units coordinate in sequence — greater coverage and lower gas consumption.

Solar power

The cannon has built-in solar panels and its own power supply, so it runs fully off-grid with no mains connection. The grid stays available as an alternative.

Frequently asked questions.

Common questions about the PGT-A80 hail cannon and hail protection.

How does the PGT-A80 hail cannon work?

Burning a mixture of acetylene and air produces a directed acoustic shock wave that disrupts ice formation in the hail cloud. Cycles repeat every 4–7 seconds while the storm passes.

How much area does one hail cannon cover?

A single PGT-A80 protects an area 1 km in diameter — a 500 m radius circle, which corresponds to up to 80 hectares of crops.

What is the annual running cost?

Around €10 per hectare per year, i.e. at most ~€800 for all 80 hectares — far less than the value of a single ruined season.

Does the hail cannon pollute?

No. Acetylene burns down to carbon dioxide and water vapor — no smoke or soot. An environmentally friendly solution.

Can it work without grid power?

Yes. The cannon has built-in solar panels and its own power supply, so it runs fully autonomously even where there is no connection to the electrical grid — with no separate station needed.
