Wireless Underwater Technology - Switzerland
Cut the Cord.
Wireless Underwater.
We are proud to distribute Hydromea - the Swiss pioneer of wireless subsea technology. From the EXRAY ultra-compact inspection ROV to the LUMA optical modems that stream 10 Mbps through seawater, Hydromea removes the tether and the bandwidth ceiling from underwater operations.
Two Technologies. One Wireless System.
A compact inspection ROV and the optical modems that set it free - used independently, or combined in the EXRAY wireless FLYOUT.
EXRAY - Compact Inspection ROV
At 9 kg and 13.4 cm tall, EXRAY reaches confined spaces no conventional ROV can enter - tanks, penstocks, ballast voids. Six degrees of freedom, 4–6 h endurance, FHD video with 4K stills, modular sensor payloads, and an optional wireless FLYOUT linked over LUMA.

LUMA - Optical Wireless Modems
The world's most capable underwater optical communication system. Five models from low-power sensor links to 10 Mbps HD video at 50 m, on 475–480 nm blue-light LEDs with a forgiving 120° beam - and 1,500× the energy efficiency of acoustic modems.

Every EXRAY package is a complete, ready-to-dive system - robot, control station, tether, 4K camera, batteries, transport case, NAVIA™ software and introductory training. The tiers differ in how much spare capacity, support and damage cover you start with.
Entry deployment
The complete system at the lowest entry cost - for a pilot project or a first EXRAY, where mission frequency is still low.
Standard operational
Doubled power, a spare wing on the shelf, an INSPECTOR STATION, priority support and 12 months of Care Package - for teams in regular field use.
Advanced / high-intensity
Full spares cover, the longest tether reach, 24 months of Care Package and warranty extended to 24 months - where downtime is expensive.
Any package can be extended with sensor payloads (DVL, UT thickness, scanning and multibeam sonar, gripper), spares, extra tether, the EXRAY™ FLYOUT wireless second robot, Care Package, extended warranty and mission support.
Swiss Engineering.
Wireless by Design.
Spun out of EPFL in Lausanne, Hydromea builds the subsea technology that lets vehicles and sensors work without cables - precise, portable and built to last.
Optical Wireless Pioneers
LUMA delivers Wi-Fi-class data through seawater - up to 10 Mbps where acoustic modems manage only kilobits. Hydromea leads the SWiG interoperability standard.
Ultra-Compact & Portable
EXRAY is 9 kg and 13.4 cm tall - carried and deployed by one person, into spaces that rule out every conventional inspection ROV.
Engineered for Endurance
4–6 hour ROV dives and sub-10 mW sleep power on LUMA sensor nodes - built for long, battery-powered operations.
Class-Approved & Swiss Made
EXRAY is DNV class approved and the hardware is Swiss-engineered and built - ready for regulated maritime, energy and defence work.
The Wireless FLYOUT
Combine the two and the tether stops at the target. The optional EXRAY FLYOUT, a second robot, docks with the tethered EXRAY and detaches where the work is; the tethered EXRAY holds station and relays live video and control over LUMA optical light, up to 30 m beyond the tether. The NAVIA™ interface is unchanged.
- LUMA nodes on the tethered EXRAY turn it into the FLYOUT's relay
- Live HD video and full 6-DOF control up to 30 m beyond the tether
- NAVIA™ sensor data transmitted alongside the video feed
- Eliminates tether snag in tanks, penstocks and confined voids
Wherever Cables Get in the Way
From confined-space inspection to wireless subsea sensor networks, Hydromea technology opens up operations that tethers and acoustic links cannot support.
Confined-Space Inspection
Tanks, pipes, penstocks and ballast voids - EXRAY enters where conventional ROVs and divers cannot, with full 4K documentation.
Hydropower & Energy
Dam walls, intake channels, turbine wells and penstock interiors surveyed without dewatering or confined-space diver entry.
AUV Wireless Comms
LUMA replaces or supplements AUV tethers - real-time command, control and data offload at up to 10 Mbps over 50 m, with docking-station links.
Subsea Sensor Networks
Low-power LUMA 100 nodes form wireless mesh or star networks for environmental, structural and oceanographic data - no cable infrastructure.
Oil & Gas
Ballast tank interiors, riser annuli and seabed sensor links - combining confined-space inspection with wireless asset monitoring.
Defence & Naval
Hull inspection, harbour security and covert, low-probability-of-intercept optical links - with no cable to manage.
Aquaculture
Net condition assessment, mooring inspection and fish-health monitoring with a compact footprint that minimises disturbance.
Deep-Sea Observatories
LUMA X's 6,000 m rating (12,000 m on request) and ultra-low sleep power suit deep-ocean observatories offloading data to passing AUVs on demand.
