About Us

At Rock Energy Systems, we are passionate about helping businesses reduce energy costs, minimize environmental impact, and operate more efficiently.

Our brands—Clean Burn, Lanair, EnergyLogic, SunFire and Air Movement Solutions—are trusted by thousands of businesses for delivering reliable performance in the harshest environments. Whether it’s a waste oil heater, a portable fuel-fired heater, or a high-performance industrial fan, our products are built to last and backed by a team that understands the demands of real-world operations.

Based in Janesville, Wisconsin, Rock Energy Systems is driven by a commitment to engineering quality, product reliability, and personalized customer service. With a nationwide network of distributors and technical support, we deliver not just equipment, but complete solutions tailored to your facility’s needs.

We don’t just build heaters—we help businesses create cleaner, more efficient, and more comfortable workplaces.
