Trusted Combustion Insight for Cleaner, Safer, More Efficient Industry

Zolo transforms invisible furnace conditions into actionable intelligence — helping steel, refining, and power operators protect assets,
cut fuel waste, and improve yield.

ABOUT

Zolo Carbon Smartech is the independent assurance backbone for combustion.

We transform in-furnace signals into actionable knowledge that protects people, assets, and compliance across the energy, steel, and refining industries.

Zolo Carbon Smartech gives industry the confidence to run at full power—without blind spots. As the independent assurance partner for combustion-driven operations, we turn advanced laser measurements into trusted, real-time insight.

With more than 20 years of proven technology and 150+ global installations, Zolo enables operators to protect people and assets, cut fuel waste, and improve yield with measurable precision. We don’t just measure combustion—we prove control, helping every plant operate safer, cleaner, and more efficiently, every single day.

What ZoloSCAN Delivers

Assurance Translated into Results.

Operate with Confidence

Real-time, in-situ combustion intelligence transforms invisible furnace conditions into trusted insight operators can act on instantly.

Protect People and Assets

Early detection of unsafe conditions—like water leaks, excess CO, or tube stress—prevents costly damage and safeguards lives and equipment.

Improve Yield and Efficiency

Tighter control of combustion reduces wasted fuel, optimizes throughput, and shortens cycle times—boosting productivity across industries.

Support Compliance
and Sustainability

Multi-species visibility (O₂, CO, CO₂, H₂O, temperature) strengthens compliance efforts and helps meet decarbonization and emissions targets.

Future-Fuel Ready
(Hydrogen / Bio-carbon)

Whether transitioning to hydrogen blends, bio-carbon, or other alternative fuels, Zolo provides the insight to operate safely, efficiently, and with confidence in new energy environments.

Long-Term Value
Through Partnership

Beyond installation, Zolo delivers monitoring, diagnostics, and service assurance—ensuring sustained performance improvements and recurring value over time.

Industries

SOLUTIONS ACROSS INDUSTRIAL DOMAINS.

Steel / EAFs

Shorten tap-to-tap cycles and detect leaks before they become incidents.
EAF operations face volatile scrap quality, rising energy costs, and the constant risk of water leaks. With ZoloSCAN’s real-time off-gas visibility, operators can shorten tap-to-tap cycles, hit endpoint chemistry with greater accuracy, and get the most out of carbon injection for stable slag foaming. At the same time, early leak detection strengthens safety and asset protection—delivering higher yield and lower costs from every melt.

Reformers

Unlock hidden efficiency and extend catalyst life with ROI proven in under 12 months.
Reforming heaters are among the most energy-intensive and risk-prone assets in petrochemical plants. ZoloSCAN2 provides multi-zone visibility across radiant and convection sections, reducing excess air, lowering tube temperature spread, and extending catalyst life. Proven results include faster startups, over $1M/year in fuel savings, and ROI in under 12 months—making reformers more efficient and more resilient.

Power & Boilers

Balance combustion in real time to cut fuel costs and extend uptime.
Boilers must maintain reliability, efficiency, and emissions compliance while adapting to variable grid demand. With more solar and renewables, operators now ramp from 25% to 100% load several times a day. Zolo’s real-time, in-situ measurements of O₂, CO, H₂O, and temperature help stabilize combustion through these transitions—reducing slagging, fouling, and tube leak risks while enabling tighter control of NOx and CO formation at the source. The result is improved uptime, lower fuel intensity, and sustained compliance—all without the drift and maintenance burden of conventional oxygen probes.

Reheat Furnaces

Improve yield and save 2–6% in fuel with multi-zone visibility.
Reheat furnaces drive rolling quality and efficiency, where temperature uniformity and fuel use directly impact costs. Zolo’s multi-zone insight helps operators maintain tighter control, reduce scale, and improve surface finish while cutting 2–6% in fuel consumption. Mills gain more consistent performance, higher product quality, and stronger margins.

Ethylene Crackers

Ethylene furnaces are among the most energy-intensive and yield-sensitive assets in petrochemical complexes.
ZoloSCAN2 provides real-time, multi-zone combustion visibility across radiant and convection sections, helping operators balance burners, minimize excess air, and reduce coking and tube stress. The result is higher ethylene yield, lower fuel consumption, and extended run lengths between decokes—delivering measurable efficiency gains and stronger process stability.

Other Industrial Applications

Zolo's technology also supports other high-temperature processes where combustion stability and safety are critical.
In biomass gasifiers and waste-to-energy units, real-time visibility of O₂, CO, and H₂O ensures stable operation and cleaner gas production. In flat glass furnaces and recovery boilers, multi-zone insight helps maintain temperature uniformity, improve efficiency, and prevent smelt-water risks. Across these diverse industries, Zolo provides the same core value—trusted, real-time combustion intelligence for safer, cleaner, and more efficient performance.

ABOUT

OUR Technology

Zolo’s platforms, ZoloSCAN™ and ZoloSCAN2™, use advanced Multiplexed- Tunable Diode Laser Absorption Spectroscopy (TDLAS) to measure combustion conditions directly inside the furnace—where safety, efficiency, and performance are defined. 

Unlike probes or extractive analyzers, our systems deliver multi-point, multi-species insight in real time, giving operators a clear, continuous view of what’s happening where it matters most. This in-situ approach eliminates lag, drift, and maintenance burdens while providing the accuracy, speed, and resilience needed to control combustion with confidence. Built for the harshest industrial environments, Zolo’s technology transforms invisible furnace dynamics into trusted intelligence that protects assets and drives measurable improvement across every operation.
