GMS Espresso uses Ultrawave ultrasonic cleaning technology for back-to-base descaling — one of the most effective methods available for removing heavy limescale and blockages from commercial coffee machine components.

The ultrasonic bath works by generating high-frequency sound waves through a cleaning solution, creating millions of microscopic bubbles that agitate and lift scale deposits from even the most inaccessible surfaces — including thin copper pipework, group heads and heat exchangers. Unlike chemical descaling, it requires no harsh chemicals and is significantly kinder to copper and chrome components.

The results speak for themselves. Components that would typically take days to clean chemically can be fully restored in as little as three hours in the ultrasonic bath.

• Reduces descaling time from days to hours
• Removes limescale and blockages from the finest copper pipework and group heads
• No harsh chemicals — safer for components and engineers
• Thoroughly cleans internal surfaces that are impossible to reach manually
• Kinder to copper, chrome and delicate internal parts
• Allows more components to be returned to service rather than replaced

A GMS back-to-base service is a comprehensive workshop overhaul for commercial coffee machines that need more than an on-site visit can provide. The full service includes:

• Engineer travel to your premises
• Machine uplift and installation of a loan machine for the duration (with training if the loan model differs from your usual machine)
• Full strip-down at our workshop
• Ultrasonic descale of all applicable components
• Replacement of all seals, gaskets and worn parts regardless of condition
• Full rebuild and safety test
• Return delivery to your site, fully tested and ready to use

Please note: replacement electronic components such as PCB boards are not included in the standard service price and will be quoted separately if required.
