Industrial Laser Cleaning Machine: Factory Direct, Zero Chemicals

A CW (continuous wave) fiber laser cleaning machine emits an uninterrupted, constant laser beam at 1064nm wavelength. The EETO FLC series outputs 1500W, 2000W, or 3000W of continuous power through a BWT or RAYCUS fiber laser source, delivering maximum average power for rapid removal of heavy rust, thick oxide scale, paint coatings, and mill scale from metal surfaces. Pulsed laser cleaners, by contrast, fire discrete nanosecond energy bursts — better for precision work on delicate surfaces, molds, and thin-gauge metals where heat input must be minimized. For high-throughput industrial applications — shipyard steel, pipeline descaling, tube bundle cleaning, structural rust removal — CW is the preferred and most cost-effective choice.

Based on factory test data: The 2000W FLC achieves 20 m²/h on oxide layer (≤20μm) and 5 m²/h on heavy rust (≤120μm) at 50mm/s scan speed with 300mm scan width. The 3000W FLC achieves 30 m²/h on oxide and 14 m²/h on heavy rust under the same conditions. These are ideal evaluation values from flat mild steel tests. For complex geometries, thick contamination, or high-alloy substrates requiring reduced power settings, real-world throughput will be lower. We always recommend sending sample materials for application testing before ordering.

The 3000W CW model consumes 12.8kW of total system power (laser source + HANLI water chiller + control system + aux gas solenoids). At this power draw, 220V single-phase delivery would require impractically high current, causing voltage drop, cable heating, and circuit breaker issues in most facility wiring. 380V 3-phase distribution is standard in industrial manufacturing facilities globally and delivers the 3000W’s power requirements safely at manageable current levels. The 1500W (6.8kW) and 2000W (8.6kW) models operate comfortably on 220V single-phase — suitable for workshops, shipyards, and maintenance environments without dedicated 3-phase power drops.

In many heat exchanger configurations — yes. Our FLC-2000 and FLC-3000 systems can be configured with fiber probe assemblies sized for insertion through nozzle access points on the shell side, or through tube sheet bore access on the tube side, enabling in-situ cleaning without full bundle extraction using a mechanical tube bundle puller or aerial bundle extractor. This is one of our highest-value applications: customers have reduced cleaning shutdown duration from 4–5 days to 6–10 hours on U-tube bundles by eliminating extraction, hydro-blasting, and acid soak steps. The critical factors are nozzle size, tube pitch, and fouling type — our engineers review the exchanger datasheet and determine feasibility during the free application consultation phase.

The cleaning threshold is the minimum laser energy density needed to vaporize or ablate the contaminant layer. The damage threshold is the energy density at which the base substrate begins to be affected. Safe CW laser cleaning operates in the window between these two values. For mild steel rust removal, this window is wide — the rust layer absorbs 1064nm laser energy 15–25× more efficiently than the steel substrate, making the process inherently self-regulating: as rust is removed and clean metal is exposed, the beam energy absorbed by the substrate drops sharply. For sensitive alloys (aluminum, copper, titanium), the window is narrower and we optimize parameters during free application testing using your exact material samples. The CQWY controller allows real-time adjustment of power, scan speed, and duty cycle to maintain operation within the safe window.

The CQWY system features an industrial touch screen HMI with a dedicated laser cleaning parameter interface. Adjustable parameters include: scanning frequency (Hz), scan width (mm), peak power (W), duty cycle (%), and modulation frequency (Hz). The system displays real-time monitoring of laser output, water chiller status, and system alarms. A secure lock function prevents unauthorized parameter changes during production — important for maintaining consistent surface cleanliness standards. The system supports recipe storage for different applications (e.g., separate parameter sets for rust removal, oxide cleaning, and paint stripping). PLC digital I/O for robot handshake and production line synchronization is standard.

Oxidation cleaning refers to removing thin oxide films (≤20μm) — typically mill scale, thermal oxide from welding (heat tint), or light surface oxidation on stored steel. These are thin, tightly bonded layers. At 3000W, the CW laser achieves 30 m²/h on these thin oxide layers. Rust removal refers to iron oxide corrosion product (Fe₂O₃, Fe₃O₄, FeOOH) that has developed to ≤120μm thickness — much thicker and more porous than mill scale, requiring significantly more laser energy per unit area to fully ablate. At 3000W, heavy rust removal achieves 14 m²/h. Contamination thicker than 120μm (deep pitting corrosion, layered rust with moisture) may require multiple passes and will reduce throughput further — sample testing is essential for thick corrosion applications.
