Good things come to those who wait. The adage rings true when it comes to Absolute Combustion International (ACI). It’s a testament to perseverance against the odds. Its founders, the late Darsell Karringten and his daughter, Koleya, never strayed from their vision.
“The concern was, will the next generation have clean air to breathe?” says Koleya, current CEO of Absolute Combustion. “What will our world look like, and how do we help shift it or leave it better than we found it?”
Founded over a decade ago, the Edmonton-based company designed a nearly flameless combustion technology that burns cleaner, significantly cuts emissions and runs on natural gas and propane — the Absolute Extreme Burner.
Originally created for the oil and gas industry, it has emerged as a game changer in aerospace, offering a viable replacement for portable aircraft heaters that haven’t been redesigned in 60 years.
Following three years of testing and development in collaboration with the Edmonton International Airport (EIA) and, after third-party testing by Versatile Engineering, the final product, ACI-SM1000 has proven to be faster and more efficient in heat transfer than any of its predecessors — it outperforms standard technologies, with 50 to 70 per cent reduction in fuel usage, and the capacity to withstand extreme cold. But the path to commercializing it has been anything but easy.
As father and daughter first set out to look at eco-friendly technologies that hadn’t been commercialized, they kept running into the same roadblock — the technology was always innovating, and never ready.
After three years of fruitless efforts, it was clear to Darsell that the only remaining option was to develop it themselves.
“We didn’t exactly know anything about combustion,” says Koleya. “So we found Brent Garossino, who did instrumentation, and we came up with this basic concept for a nozzle, and they built it around that.”
But it wasn’t until four years ago that the company established its first long-term partnership, with EIA. In 2016, Koleya was invited by the Alberta Government to a tech conference in Japan. As a group of experts looked at her company’s technology prior to the conference, the promising and innovative concept left no room for doubt. At the time, the conventional aircraft heater couldn’t heat up at temperatures below -20 degrees Celsius. It needed help from the plane’s auxiliary power unit that “guzzled gas like nobody’s business,” as Koleya puts it (174 litres of fuel per hour on a Boeing 737-200, for example). Not surprisingly, Absolute Combustion was tasked with redesigning it.
