Hot-dip galvanised suppression: STG Global

Ashley Joseph, STG Global CEO, speaks with Waste Management Review about engineering high-powered water trucks from the user up.

In May last year, just two months after the World Health Organisation declared a global pandemic, STG Global launched a range of disinfectant spray trucks to contain COVID-19.

Originally designed for the plant and equipment market as a dust suppression powerhouse, the launch of STG’s Suppressor COVID-10 Destroyer highlights the company’s innovative spirt and ability to pivot manufacturing towards new needed services and equipment.

According to Ashley Joseph, STG Global CEO, the Suppressor Truck is the only Australian-made truck capable of deploying disinfectants over a large outdoor expanse – as one effective measure of containing an outbreak of COVID-19 in a particular suburb, town or outdoor area.

Going forward, the Suppressor Truck could be used in containment efforts where an outbreak occurs in a condensed geographic area, as the Australian government seeks to supress clustered outbreaks.

Joseph explains that the Suppressor – one of multiple in STG’s hot dipped galvanised water truck range – is designed to last up to three hours on-site, making the unit a more efficient and viable solution than traditional water trucks.

“We’re the only manufacturer in Australia that hot-dip galvanises our products, so our tanks are some of the toughest and most reliable on the market,” Joseph says.

“Being hot-dip galvanised, the tanks don’t rust, which is a key concern when dealing with water tanks.

“The life of our trucks is almost double the life you’d get elsewhere.”

While it can be reconfigured into the COVID-19 Destroyer model, the Suppressor’s historical function has been dust suppression, with a water cannon and individual cannon controls providing operators with a 100-metre spray range.

The Elkhart Brass cannon with fog nozzle works to help operators comply with EPA, Worksafe and council requirements, while mitigating risks and preventing unnecessary costs and environmental regulator scrutiny.

“One of the issues our customers were facing was water being used up too quickly,” Joseph explains.

“When you’ve got a 13 to 18,000 litre tank and are spraying water onto the ground, it only takes 20 minutes to empty the tank, so there’s a lot of wasted water.

“We developed the idea of spraying a mist of water to bring dust down, and that’s how the Suppressor was born.”

A lot of bigger sites use static equipment to suppress dust, Joseph adds, whereas STG came up with the idea of developing a movable piece of plant – allowing operators to move the Suppressor as wind and environmental conditions change.

The Suppressor is just one in STG’s range of water trucks, which features both hot-dip galvanised steel tanks and innovative Polytanks.

“One of the key issues coming online at the moment is weight, so we wanted to design a product that had the same STG look and performance capabilities but didn’t have the same weight as a steel tank,” Joseph says.

STG developed the Polytanks with the resulting units the only Polytanks manufactured in Australia with internal pipework.

“Most trucks have pipework sitting on the back of the unit, so if an operator wanted to have a spray bar at the front of the tank, the pipe would have to come up over the tank,” Joseph says.

“What we’ve done is engineer the trucks to incorporate all of the pipework internally, with outlets at the top and side of the tank.

“This works to minimise maintenance costs as the pipes won’t be subject to wear and tear, while also facilitating a more attractive, streamlined unit.”

STG’s water truck range is versatile, with customers including waste and landfill operators, councils and mining, civil works and agricultural companies.

Joseph adds that the 100 per cent Australian made trucks can be customised with company colours and come backed up with STG’s country-wide after sales support network.

“Reliability and dependability are what we hang our hat on when it comes to our water trucks,” he says.

“My partners started their lives as machinery operators, so we’ve developed the range from the user up rather than from the engineer down.

“They are a strong, overengineered and tough product.”
