A CW (continuous wave) laser cleaning machine delivers a sustained, uninterrupted beam output throughout the cleaning pass. Unlike a pulsed system, which fires in discrete bursts, the CW laser fires continuously — maintaining high average power across the entire stroke. That uninterrupted energy delivery is what drives throughput on heavy contamination and thick coatings. Pulsed systems deliver higher peak power in very short bursts, which suits precision cleaning of delicate or heat-sensitive surfaces where brief, controlled energy deposition is preferable. Neither is universally superior — they address different cleaning regimes. ELASER operates at up to 200 kHz with an adjustable pulse repetition rate, giving the operator direct control over the cleaning regime and allowing the machine to be tuned toward different surface and contaminant combinations.

No. ELASER is fully air-cooled — no water connection, no chiller, and no coolant circuit is required. This is a genuine operational differentiator at this power level; many high-power CW laser cleaners require external cooling infrastructure. ELASER runs from a standard single-phase 110–250 VAC supply and needs no site preparation or plumbing. In practice, that means the machine deploys wherever a power socket is available: factory floor, outdoor sites, heritage locations, mixed-use facilities — without any advance infrastructure work.

ELASER is available as Class IV or Class I. Class IV is the standard industrial classification for high-power laser systems and requires a controlled laser zone with appropriate PPE. Class I is the highest built-in safety classification, suitable for environments where the machine itself must carry the classification. The critical differentiator is the ELASER-RHZ: WSL's patented, world-first technology collapses the laser hazard zone to a fraction of conventional size, enabling cleaning in open workshops, mixed-use facilities, and publicly accessible settings without requiring full area evacuation or shutdown. Operator training remains important regardless of variant — WSL provides full safety and operation training to all buyers. The HSE publishes guidance on laser safety classifications at hse.gov.uk/radiation/optical/lasers.htm for buyers who want further regulatory context.

ELASER cleans a wide range of surfaces: metals including steel, carbon steel, aluminium alloys, cast iron, copper, brass, bronze, titanium, and galvanised steel; plus stone, concrete, brick, and masonry. On those surfaces it removes 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. The breadth is possible because of 0–100% power tunability: the operator sets beam intensity above the contaminant's ablation threshold and below the substrate's — the beam stops at the base material, leaving the surface intact.

The handheld scanner weighs under 3 kg; the wheeled system unit is under 50 kg; the delivery cable reaches up to 50 m. One operator deploys and runs the full system without assistance. The sub-3 kg scanner is light enough for sustained use without fatigue. The wheeled unit moves between workstations or into the field without lifting equipment. The 50 m cable reach means the operator can access the work without relocating the main unit. A standard single-phase 110–250 VAC supply is all that is needed — no compressor, no water supply, no consumables to manage.

WSL provides first-class safety and operation training directly to buyers — no dependency on a third-party training provider. The touchscreen GUI with password-protected access and per-user logins is designed for straightforward day-to-day operation; it does not require a laser engineering background to use. That said, proper operator training is a requirement, not optional. ELASER is a Class IV laser (or Class I), and safe use depends on trained operators. WSL trains your team directly, so you have the knowledge to use the machine confidently from day one.

Yes. ELASER carries both CE and UKCA certification. CE confirms compliance for EU markets; UKCA confirms compliance for the UK market following Brexit. For UK industrial buyers, UKCA is the relevant mark for placing equipment on the UK market. The HSE provides guidance on the UKCA marking and its relationship to CE at hse.gov.uk/work-equipment-machinery/brexit.htm.

Pricing is application-specific — contact WSL directly for a quote tailored to your requirements. In terms of market positioning: ELASER is the European cost leader among comparable industrial CW laser cleaning machines, competitively priced relative to the market. That competitive pricing is achieved through WSL's technological and operational efficiencies, not by reducing quality. To request a quote, get in touch with the WSL team.

Yes. WSL offers bespoke engineering and customisation for buyers with specific requirements. If you have an unusual application, a specific integration need, or a non-standard requirement, contact WSL directly to discuss what is possible — the team is the right starting point for that conversation.

ELASER is designed, built, and supported by Woodrow Scientific Limited (WSL) — the only UK-based laser cleaning manufacturer. WSL is not a reseller or importer; every machine is engineered in-house in Britain. Founded in 2012, WSL brings over 200 years of combined engineering experience to the product, including the patented ELASER-RHZ reduced hazard zone technology as evidence of genuine original engineering capability. For buyers, in-house manufacturing means the engineers who designed the machine are the same team who support it — faster problem resolution, real product improvement capability, and no dependency on an overseas third party for spares or fixes. It is worth noting that a number of suppliers in the laser cleaning market are resellers or importers rebadging third-party machines; WSL's in-house model is a meaningful distinction when evaluating long-term support.
