RainGun road dust suppression system for the Stone Crusher Association at Karanampettai, Coimbatore region

The association's road dust suppression system — the largest single installation in the region.

One Association, Twenty Years, Most of a Region

Our dust control work started in Coimbatore, Tamil Nadu in 2004. Since then we have completed more than 30 projects in the region, all for members of the same crusher owners' association. Between them, those installations now cover almost 80% of the mining industries in the region.

About half are repeat customers coming back with extension projects; the rest are new industries that joined as the association grew. Some take machine side dust control, some road side dust suppression, and many take both.

The Road Project, Built in Two Stretches

The most important project in the region is the association's own road system, and it was not built all at once. The first stretch put 100 RainGuns along 1.2 km of road. It was later extended with 200 more RainGuns in 2026, and handed over complete with GSM on/off control.

Today 4.5 km of road is dust controlled every single day, and one person operates the entire system. That is the point of the GSM control: on a line that long, the alternative is a man walking the road opening and closing valves, and suppression that lapses the moment he is needed elsewhere.

The extension is worth noting on its own. A road system that can be tripled in length years later — without rebuilding the original stretch — has to have been designed with pumping and pipeline headroom from the start.

Built for the Water That Actually Exists

This is a heavy water shortage area. There is simply not enough fresh water to run dust suppression at this scale, so the association operates a separate water tanker lorry bringing waste salt water from nearby sources. The system had to be built to tolerate poor quality water from day one — which is a very different design brief from a site with a clean borewell.

Frequently Asked Questions

How many crusher units in the Coimbatore region use Thumba dust control?

More than 30 projects for members of the same crusher owners' association, covering roughly 80% of the mining industries in the region. About half are repeat customers returning with extension projects; the rest are new industries. Some take machine side dust control, some road side dust suppression, and many take both.

How many people are needed to run a 4.5 km road dust suppression system?

One. The association's system covers 4.5 km of road every day and a single person operates the whole installation, because the RainGuns are switched by GSM on/off control rather than by walking the line and opening valves by hand.

Can a dust suppression system run on salt water or poor quality water?

It has to in this region. Coimbatore's crusher belt is a heavy water shortage area, so the association runs a separate water tanker lorry bringing waste salt water from nearby sources. The system was designed from the start around the water actually available, rather than assuming a clean supply.

Can a road dust control system be extended after it is built?

Yes, and this one was. The association's road project went in as two stretches — 100 RainGuns along 1.2 km first, then 200 more added in 2026 to reach the 4.5 km covered today. Designing the pumping and pipeline with headroom is what makes a later extension possible without rebuilding the original stretch.
