The handheld laser cleaning machine with a CW (Continuous Wave) laser source and industrial water chiller is an advanced surface treatment solution designed for modern manufacturing environments in Europe and North America. It delivers high cleaning efficiency, consistent performance, and long-term cost savings while fully supporting environmental regulations, workplace safety standards, and Industry 4.0 requirements.
The laser cleaning machine removes surface contaminants by directing a controlled laser beam onto the target area. The laser energy is absorbed by rust, oxides, oil, grease, paint, or coatings, causing rapid thermal expansion and vaporization. The base material—steel, aluminum, stainless steel, or other metals—remains unaffected due to its different absorption characteristics.
Key technical characteristics:
Non-contact process – no mechanical stress
No consumables – no chemicals or abrasives
Highly controllable energy output for consistent results
The CW laser cleaning machine provides stable and continuous laser power, making it particularly suitable for large-area cleaning, heavy rust removal, and pre-welding surface preparation in industrial production lines.
Compared with chemical cleaning, sandblasting, wire brushing, or solvent-based processes, the laser cleaning machine offers clear advantages valued by European and North American manufacturers.

Both air cooling laser cleaning machines and water cooling laser cleaning machines offer unique advantages depending on operational requirements. Similarly, the choice between a CW laser cleaning machine and a pulse cleaning machine depends on the balance between cleaning speed, precision, and thermal sensitivity.
By selecting the appropriate laser cleaning machine, manufacturers can significantly improve cleaning quality, reduce operating costs, and comply with modern industrial and environmental standards.


Laser Cleaning controlling system, currently the main in the market is SUP laser cleaning system with professional cleaning gun, which customization is available

The Laser source mainly in the market is Raycus & Max photonics, and other brands are also available such as RECI, Everfone, BWT etc.
Currently the Maximum laser source for the water cooling type is 6000W
Q1: What is the Maximum Laser Power for the Handheld Laser Cleaning Machine?
Answer: As it is the water cooling laser cleaning machine, once we use a higher volume of the chiller for the enough cooling, now the tested maximum power is 6000W
Q2: What is the Maximum Cleaning Width for the Handheld laser cleaning machine?
Answer: The cleaning width is effected by the focus diameters, once the focus diameter is bigger, the cleaning width is bigger, currently the cleaning width is 500mm
Q3: What is the obvious difference between CW laser cleaning machine & Pulse Cleaning machine
Answer: CW is continuous Wave, high powre output, is harmful to base material, but pulse laser source is different, is high peak but short time output, which no harmful to the base material, so the final application is different, Pulse laser source is mainly for the precise cleaning, also for the wood,paper etc.
Q4: Is it possible to do the OEM and ODM for our products?
Answer: Yes, it is possible, thanks to the supply chains, we can offer the customization from the water cooling cabinet, machine color, controlling system, cleaning gun, laser source etc. with a good relationship with the suppliers, we can offer a good quality with attractive prices, we also welcome to your inquiries
