ELASER-RHZ
The world's first reduced hazard zone laser cleaning machine.
The ELASER-RHZ is our pioneering Reduced Hazard Zone cleaning system — engineered and built in the UK, and the only laser cleaner of its kind anywhere in the world.
Ordinary industrial cleaning demands a sealed-off, evacuated area before anyone can start; RHZ technology collapses that hazard zone to a fraction of the size, so cleaning can happen in open workshops, mixed-use facilities and public-facing settings more effectively.
A single operator lifts away rust, paint, coatings and ingrained contamination across almost any material, using laser light alone — no chemicals, no abrasive grit, no water. Just plug it in and clean.

Surfaces
Laser cleaning removes the contaminant with minimal substrate loss, so you don't clean away what matters.
Removes
Adjustable power tunes to each layer, so one machine lifts everything from light oxides to thick coatings.
A focused, pulsed laser beam is aimed at the surface. Each pulse carries just enough energy to vaporise the unwanted layer — rust, paint, coating or residue — and flash it away.
A very wide range. Because the power is fully adjustable, one machine moves from delicate work — soiling, light oxides, graffiti on stone and masonry — right up to heavier weld scale and industrial coatings
Yes, by default our laser cleaning systems emit class 4 radiation due to the high power and energy pulses required for effective cleaning.
However, we have developed advanced engineering controls that ensure access to any radiation greater than class 1 is not possible.

Laser cleaning doesn't use any chemicals or abrasive media, so there's:
- Less (negligible) damage to the underlying surface.
- Less ongoing costs (our ELASER runs directly from your mains supply).
Very little. Running on electricity, there are no abrasives, chemicals, or other consumables to buy in or dispose of.
Yes, we do.
Yes. In-house engineering is one of our core strengths, and we regularly adapt systems around a customer's specific parts, environment or process. If your requirement isn't met by the standard configuration, let us know.
There are three.
This is the "eye-safe" (RHZ) model, built for enhanced safety.
There's also the standard handheld system for general portable cleaning, and AutoLASE: a robot-mounted version for automated production.
Almost certainly - we deliver our machines to customers all across the globe.
"Eye-safe" is the shorthand, but the accurate term is Reduced Hazard Zone (RHZ): it minimises the zone that you need to operate the machine. This makes it possible to use effectively for wider applications, such as in public spaces.

Components
Everything You Need in One Small System
Everything you need is packed into one compact, lightweight unit you can wheel straight to the job.
No compressor, no water supply, no consumables to haul around: just plug it in and a single operator is ready to clean.
Reduced Hazard Zone Technology
Elaser-RHZ uses our patented "eye-safe" technology to minimise the hazard zone required, making it viable for more applications.
Lightweight Scanner
A sub-3 kg handheld scanner with a 2-D galvanometer and 10 m/s max scan rate.
Portable Design
Compact and wheeled, and light enough for one person to move unaided — roll it from the workshop out to site and on to wherever the next job is.
Touchscreen
Dial power anywhere from 0–100% on the touchscreen to match each surface, with individual user logins keeping access secure.
Fibre-optic Delivery Cable
A delivery cable up to 50 m long brings the beam to far-off or awkward spots, so the unit can stay put while you reach the work.
Applications
