Tørisblæsning: Case Study

A mid-sized shipyard in Denmark struggled with propeller shaft maintenance for months. Their traditional dry ice blasting setup required 45 minutes per shaft and left oily residue in critical crevices. The compressor noise disrupted nearby welding operations, and dry ice procurement costs were climbing 15% quarterly. Three technicians spent hours prepping the workspace just to contain the CO₂ pellets.

The operations manager contacted Klear Laser after seeing a demonstration of pulsed fiber laser cleaning. They tested our 2000W pulsed laser system on a corroded shaft section. The laser removed salt corrosion, old grease, and surface rust in 12 minutes without disassembly. Pulse width modulation protected the machined surfaces while breaking down oxidation layers. The process was silent, produced no secondary waste, and required only one operator.

Six-month efficiency gains shocked the management team. Cleaning time dropped 73%. Labor costs fell by $8,400 monthly. The eliminated dry ice deliveries and disposal fees saved another $3,200 per month. Most importantly, the laser’s precision prevented substrate damage that had previously scrapped two high-value shafts annually.

Comparison of Industrial Cleaning Methods

The shipyard now cleans eight shafts per shift instead of three. Their quality control reports zero surface damage incidents since switching. The laser system paid for itself in 11 months through operational savings alone. This represents the industrial reality: laser technology has surpassed dry ice blasting in every measurable performance category while eliminating environmental complications.

Key Features & Advantages

Klear Laser’s laser cleaning technology delivers exceptional rust removal through high-quality components. The core advantage lies in our industrial-grade laser sources from JPT or Raycus. These sources generate the consistent, high-peak-power pulses essential for efficient ablation of thick, adherent rust layers without damaging the underlying substrate.

The optical cleaning head is engineered for performance and adaptability. It features a dynamic scanning system with a protective sapphire window, ensuring precise beam delivery across diverse surfaces. Crucially, the head allows real-time adjustment of the focal point and spot size, optimizing energy density for maximum cleaning efficiency on intricate shapes while ensuring minimal heat input.

Substrate safety is paramount. Klear Laser machines offer exceptional control over critical parameters. The ultra-short pulse width (down to tens of nanoseconds) ensures energy is delivered faster than the target material’s thermal diffusion time. This prevents heat buildup, eliminating the risk of warping or altering even sensitive base metals like thin steel or aluminum alloys during rust removal.

Industrial Applications

“Tørisblæsning” is the Danish term for dry ice blasting, a non-abrasive cleaning method that uses solid CO₂ pellets accelerated by compressed air to remove contaminants from surfaces. While effective in many industrial settings, Klear Laser replaces tørisblæsning with advanced pulsed laser cleaning systems in sectors like automotive, aerospace, and marine—where precision, repeatability, and substrate safety are critical.

In the automotive industry, dry ice blasting is used to clean molds, engines, and production lines without disassembly. However, laser cleaning offers superior control, especially for removing rust, oil, paints, and oxides from aluminum and steel components without surface damage. It also eliminates consumables like CO₂ pellets, reducing operational costs.

In aerospace, maintaining structural integrity during maintenance is crucial. Dry ice blasting is sometimes used for paint stripping or cleaning turbine parts, but it risks moisture retention and inconsistent results. Klear Laser’s pulsed fiber laser cleaners deliver precise rust and coating removal from titanium, aluminum alloys, and composites. With adjustable pulse width and energy density, our systems preserve the underlying substrate while ensuring complete contaminant removal.

In marine environments, rust on steel hulls, decks, and pipelines is a persistent challenge. Dry ice blasting offers quick cleaning but lacks deep rust penetration and leaves behind moisture, accelerating re-oxidation. Klear Laser systems eliminate this risk—removing mill scale and rust to Sa 2.5 standards without damaging the base metal or requiring chemical additives.

Klear Laser’s pulsed fiber laser cleaning machines outperform tørisblæsning in control, environmental safety, and long-term cost efficiency. By replacing CO₂ media with focused photonic energy, we deliver zero secondary waste, no water, and no consumables—making our technology ideal for high-specification sectors where reliability and cleanliness are paramount.
