Hanten SEAL2 3000W Continuous Laser Cleaning Machine

3000W Continuous Laser Cleaning Machine That Strips Heavy Rust and Thick Paint Across a 300 mm Swath

The Hanten SEAL2 3000W pairs a 3000W continuous-wave fiber laser with a sub-1 kg handheld cleaning gun, a 300 mm maximum cleaning width, an 800 mm working distance, and an integrated water-cooled cabinet built for long industrial shifts.

Large rusted frames, painted steel, mill scale, and oil-soaked equipment are where sandblasting, grinding, and chemical strippers eat the most time and money. Blasting needs media, containment, and cleanup; grinding wears out discs and operators; strippers bring disposal costs and fumes. A high-power continuous-wave laser cleaner removes the same contamination with light, so there is no media to buy and no chemical waste — only the stripped residue to collect.

The Hanten SEAL2 3000W Continuous Laser Cleaning Machine (model HTCL3000) is the top power tier of Hanten's SEAL2 continuous line, built for fabrication shops, structural steel, equipment refurbishment, and maintenance crews that clean large surfaces every day. It combines a 3000W continuous fiber source, a lightweight handheld cleaning gun, a protective retractable touchscreen, and a water-cooled cabinet on wheels.

Strip Heavy Rust at Up to 50–60 m² per Hour on Thin Corrosion

Hanten's laboratory data rates its 3000W continuous cleaners at 50–60 m² per hour on rust layers up to 50 µm, about 30 m² per hour on 50–100 µm rust, and about 20 m² per hour on rust thicker than 100 µm. A continuous-wave laser holds a steady beam on the surface instead of firing short pulses, so it pours far more average energy into the contamination every second — that is what makes it fast on broad, heavily corroded areas where a pulsed cleaner would need many passes. For a shop stripping trailers, structural members, or equipment housings, that throughput is the difference between a cleaning job that takes a shift and one that takes a week.

Cover a 300 mm Swath From 800 mm Away So Large Surfaces Go Faster and Safer

The SEAL2 sweeps a maximum cleaning width of 300 mm at a focal (cleaning) distance of 800 mm. A wider swath means fewer overlapping strokes on panels, beams, and hulls, which cuts cleaning time on large areas, and Hanten's straight-line scan pattern is designed to clean every strip without leaving missed spots. The long working distance keeps the operator further back from the work surface and the debris it throws off, which is both more comfortable and safer on big jobs.

Keep Full Power Stable Through Long Shifts With Integrated Water Cooling

At 3000W the laser source and optics generate serious heat, so the SEAL2 uses a built-in water-cooling system to hold the machine at a stable operating temperature. Stable temperature means stable output: the laser keeps delivering consistent power hour after hour instead of drifting or tripping protection as it heats up. Hanten specifies an optimal working environment of 10–40°C, and the cabinet rolls on wheels so the whole system — source, cooling, and controls — moves together around the shop floor.

Hold It All Shift: a 0.9 kg Gun With a Safety Lock and Dual-Trigger Control

The handheld cleaning gun weighs just 0.9 kg, light enough for long sessions, overhead work, and awkward angles without wearing out the operator. It carries a safety lock and dual-trigger control, so the laser only fires when the operator deliberately engages both — a second layer of protection against accidental emission on a busy shop floor. Routine maintenance is simple too: unscrew the cover plate and the focusing lens comes straight out for replacement, which keeps downtime short.

Protect the Controls on Dusty Job Sites With a Retractable Touchscreen

The SEAL2's touchscreen retracts into the cabinet when it is not in use, shielding it from dust, debris, knocks, and weather — the things that crack or cloud exposed screens on working machines. When it is out, the interface runs in 8 languages (English, Simplified and Traditional Chinese, Japanese, Korean, Russian, German, and French), switchable directly on the screen. A protected control panel is one less part to replace on a machine that spends its life around abrasive residue.

Use Continuous Wave Where It Wins — and Pulsed Where Precision Matters

Continuous-wave cleaning trades finesse for speed. Because the beam never switches off, it delivers more heat into the surface than a pulsed laser, which is exactly why it strips thick rust and paint so quickly on structural steel, castings, and heavy plate. That same heat makes it the wrong tool for thin sheet, molds, precision parts, or surfaces where the original finish must be preserved — those jobs belong to a pulsed laser cleaner, which removes contamination in nanosecond bursts with minimal heat input. Matching the technology to the work is the single biggest factor in getting a good result from laser cleaning.

Plan Power, Air, and Extraction Before It Arrives

The 3000W SEAL2 runs on a 380V industrial power supply. That is not a standard North American shop voltage, so most U.S. and Canadian facilities will need a properly rated transformer or an existing 380V service before the machine can run — confirm your site power before you order. If your shop only has 220V, the SEAL2 2000W and 1500W share this machine's gun, cabinet and optics and run on 220V. Hanten recommends an air compressor with an oil-water separator for high-power, heavy-dust, or continuous work, because dry, oil-free air blown across the protective lens means fewer lens replacements and less downtime, and a smoke purifier to pull dust and fumes out of the work area. An optional 2 kg wheeled support bracket carries the gun along floors and flat surfaces and adds a dust-extraction port, so operators are not bent over holding the gun all day.

Hanten Continuous Laser Cleaners Compared: SEAL2 1500W, 2000W, 3000W and 6000W

Choose the SEAL2 3000W if heavy rust and coating removal on parts, frames, and structural steel is daily work and you have, or can add, 380V industrial power. Choose the SEAL2 1500W or 2000W if your shop only has 220V or your rust is mostly light to moderate — the 2000W is the most power available on 220V. Choose the 6000W if you strip ship hulls, storage tanks, bridges, or other very large steel surfaces where doubling throughput pays for the bigger system.

Frequently Asked Questions about the Hanten SEAL2 3000W Continuous Laser Cleaning Machine

Q: How does the Hanten SEAL2 3000W compare with the SEAL2 1500W, SEAL2 2000W and the 6000W?
A: The three SEAL2 models share the same cabinet, 0.9 kg gun, 300 mm cleaning width and 800 mm working distance, and differ in power and throughput: Hanten's lab data puts the 3000W at 50–60 m²/h on rust up to 50 µm, versus 25–30 m²/h for the 1500W and 35–40 m²/h for the 2000W. The 1500W and 2000W run on 220V, while the 3000W needs 380V. The 6000W roughly doubles the 3000W at 100–120 m²/h, with scan widths up to 500 mm and a 2.2 kg dual-handle head, and suits ship hulls and bridges rather than shop and yard work.

Q: What can a 3000W continuous laser cleaner remove?
A: Heavy rust, thick paint and coatings, oxide layers, mill scale, oil, and grease from metal surfaces. Hanten shows the SEAL2 stripping paint up to 1 mm thick. It is designed for robust metal parts and structures rather than delicate or finished surfaces.

Q: What is the difference between continuous-wave and pulsed laser cleaning?
A: A continuous-wave laser runs a constant beam and delivers high average power, so it removes thick rust and paint quickly on large metal areas but puts more heat into the part. A pulsed laser fires very short, high-peak bursts with minimal heat transfer, which is better for thin metal, molds, precision parts, and restoration where the substrate finish matters.

Q: Will it damage thin metal or precision parts?
A: It can. Continuous-wave cleaning delivers more heat than pulsed cleaning, so thin sheet, molds, and precision components risk warping or surface change. For those parts, a pulsed laser cleaner is the right choice; use the SEAL2 3000W on heavier steel, castings, and structures.

Q: What power does the SEAL2 3000W require?
A: It runs on a 380V industrial supply. Because 380V is not a standard North American shop voltage, most U.S. and Canadian facilities will need a correctly rated transformer or existing 380V service. Contact The Maker's Chest before ordering to confirm your site power.

Q: Does it need a separate water chiller?
A: No separate chiller is needed — water cooling is built into the cabinet. Keep the machine within Hanten's optimal 10–40°C working range and protect the cooling system from freezing if it is stored in an unheated space.

Q: Do I need an air compressor and a fume extractor?
A: Hanten recommends an air compressor with an oil-water separator for high-power, heavy-dust, or continuous use to protect the lens, and a smoke purifier to remove dust and fumes. Both are optional accessories sold separately; at 3000W the volume of stripped residue is high, so extraction is strongly recommended indoors.

Q: How does laser cleaning compare with sandblasting?
A: Laser cleaning uses no abrasive media or chemicals, creates no media cleanup, and leaves only stripped residue to collect. It also avoids the substrate erosion that blasting can cause. Blasting can still make sense for some very large or complex jobs, but laser cleaning removes the recurring cost of consumables and containment.

Q: Do I need special training or certification to operate it?
A: No certification is required to buy it, but this is industrial Class 4 laser equipment. It requires laser-rated safety eyewear, a controlled work area, caution around reflective surfaces, and proper fume handling. Read the manufacturer's safety documentation before first use.

Q: What warranty, returns, and support come with the SEAL2 3000W?
A: Hanten provides a 1-year warranty on the whole machine and a 2-year warranty on the laser source, plus remote guidance and lifelong after-sales support. Through The Maker's Chest you also get 75-day returns: return the unit unused and in its original packaging within 75 days of delivery, with return shipping paid by the customer.

Q: Why buy through The Maker's Chest instead of directly from Hanten?
A: Hanten is a manufacturer based in Jinan, China. Buying through The Maker's Chest gives you 75-day returns, a U.S.-based team for questions on 380V power, continuous versus pulsed cleaning, compressed air, and fume extraction, and the option to pair the machine with extraction equipment from one retailer.
