Advanced Catalytic Technology

ECOplus FlameKat –
Next-Gen by HARK

A Breakthrough in Wood-Burning Technology
____

For decades, manufacturers have worked to make wood combustion cleaner and more efficient. With the introduction of ECOplus technology, HARK set new standards in emission reduction. Now, the ECOplus FlameKat takes this development even further.

Fully integrated directly above the flame inside the combustion chamber, the catalytic system reduces particulate matter and gaseous emissions at the source. Independent testing confirms sustained performance at temperatures up to 1,550°F without measurable loss of efficiency.

Unlike conventional catalytic systems that operate at significantly lower temperatures and need frequent maintenance, the ECOplus FlameKat is self-regenerating under high heat. If necessary, it can be cleaned easily with water. No electricity is required for its operation.
