Frost Kraftentreprenør has developed a patented method for cleaning electrical substations without interrupting power supply. The HotBlast solution is already in use across Europe and is gaining traction for its safety, speed and sustainability.
CHALLENGE
Costly downtime and environmental impact
Electrical substations and grid components often suffer from pollution build-up due to industrial activity, agriculture and airborne particles, particularly in urban areas, which can cause costly unplanned outages.
Traditionally, cleaning these components requires shutting down power, dismantling equipment and using chemicals – resulting in downtime and environmental impact. There is growing demand in the industry for safer alternatives, particularly where water-based cleaning methods could damage sensitive production facilities.
SOLUTION
HotBlast dry ice cleaning method from Frost Kraftentreprenør
The unique, patented HotBlast is a dry ice cleaning method that works while facilities are in operation. It is safe for installations with voltages up to 34 kV and does not require dismantling of equipment. A transformer can be cleaned in just 15 minutes, with no abrasive effect.
“This allows HotBlast to be used in a wide variety of applications, from sensitive electrical components to more robust industrial objects,” says Thomas Wilsgaard, Project Lead at Frost Kraftentreprenør.
BENEFITS
Environmentally sustainable and efficient
The method is not only fast and flexible, but it also helps to reduce waste as no abrasives are used. “HotBlast is a gentle but powerful technology that uses dry ice instead of chemicals,” explains Wilsgaard.
The dry ice turns into gas and leaves no residue, significantly reducing environmental impact.
MARKET POTENTIAL
Growing demand for maintaining electricity grids
There is increasing pressure to modernise electricity grids in Europe and elsewhere, and advances also need to be made in how grids are maintained.
HotBlast is already in use in Austria, Germany and Norway, with expansion underway in Portugal and Spain.
“There is high demand in the industry, especially in cases where water-based cleaning methods could damage sensitive production facilities,” states Jan Erik Edwardsen, Sales, Consulting and Training Manager at Frost Kraftentreprenør.
