The ELASER-RHZ uses WSL's patented reduced hazard zone (RHZ) technology — a world-first — to confine the laser hazard to a small area immediately around the work. This means cleaning can proceed in open workshops, mixed-use manufacturing facilities, and publicly accessible spaces such as heritage sites or graffiti removal jobs, without sealing off or evacuating the surrounding area. No other laser cleaner in the world offers this capability. The standard ELASER operates as a Class IV laser system, which requires a controlled laser zone to be established before work begins. The ELASER-RHZ operates at Class I. Both are portable, wheeled systems with the same sub-3 kg handheld scanner and up to 50 m cable reach — the RHZ variant simply unlocks a far wider range of deployment environments.

ELASER cleans a broad range of surfaces: steel, carbon steel, aluminium alloys, cast iron, copper, brass, bronze, titanium, galvanised steel, stone, concrete, brick and masonry. Contaminants removed include rust, oxides, mill scale, paint, powder coating, lacquer, primer, oil and grease, carbon and soot, mould, graffiti, adhesives and residues, tarnish, weld discolouration, and release agents. Power is tunable from 0–100%, so one machine spans delicate tasks — lifting light tarnish or thin oxides — through to heavy-duty removal of thick industrial coatings and mill scale. The beam stops at the base material throughout, leaving the substrate intact.

Yes. WSL provides first-class laser cleaning safety and operation training as a standard part of the ELASER offering. Appropriate operator training is a practical and regulatory requirement for Class IV laser equipment in the UK — the HSE's guidance on laser safety sets out these expectations clearly. WSL delivers training in-house, carried out by the engineers who design and build the machines. As the only UK-based laser cleaning manufacturer, WSL is uniquely positioned to provide training that is directly tied to the product — not a generic course from a third party. Training covers both safe operation and optimisation for your specific applications.

ELASER holds both CE certification and UKCA certification, and is manufactured in Britain. CE confirms compliance with the relevant product safety and electromagnetic compatibility requirements for European markets. UKCA is the UK conformity marking required for the GB market following the UK's departure from the EU. Both certifications confirm that ELASER meets the applicable product safety standards for its respective markets. The gov.uk product marking guidance provides a clear explanation of what each marking means in practice for buyers who want to understand the regulatory context in more detail.

Yes. Laser cleaning is a well-established industrial process, not an emerging or experimental technology. Pulsed laser energy is absorbed by the contaminant — rust, paint, mill scale, oil, carbon, and others — which vaporises or is ablated from the surface. The beam stops at the base material, leaving the substrate intact. The technology is in active use across automotive manufacturing, aerospace maintenance, heritage restoration, and general industrial cleaning. It is effective on metals, stone, concrete, and masonry. Independent technical sources including ASM International confirm laser cleaning's effectiveness on industrial substrates. The practical results — clean surface, no substrate damage, no consumables — are consistent across applications.

Pricing for portable industrial laser cleaning machines varies significantly by power class, configuration, cable length, and manufacturer. ELASER is priced by quotation — contact WSL for a tailored figure based on your specification. Among comparable industrial-grade portable laser cleaners, ELASER is the European cost leader, with competitive pricing achieved through in-house manufacturing efficiency rather than any compromise on quality. The more meaningful comparison, however, is total cost of ownership: laser cleaning requires no abrasive media, no chemicals, no waste disposal, and causes minimal substrate damage — reducing rework. Over a machine's working life, those savings change the cost picture substantially against traditional methods such as sandblasting or chemical stripping. Contact WSL to discuss the configuration that fits your application and budget.

Cleaning speed depends on power and contaminant type. Higher power cleans faster; thick coatings across large surface areas take longer than light oxides on small components. For very high-throughput cleaning of large areas, higher-power or automated systems may be more efficient than a handheld portable unit. Operator training is required. Class IV laser equipment demands qualified, trained operators — this is a practical reality, not a barrier. WSL provides full safety and operation training as standard. The initial investment is higher than some traditional methods such as sandblasting or grinding. That said, laser cleaning carries no ongoing consumable costs, no media disposal overhead, and causes minimal substrate damage — reducing rework. Across a machine's working life, the total cost of ownership picture is typically stronger than traditional alternatives.
