The breathing performance of D-ONE Reclaim has been independently verified using Heliox at simulated depths of up to 350 metres seawater.
Conducted at DRASS Lab, the home of in-house and third-party testing of ultra-deep underwater technology, this campaign quantified and certified stable breathing-system operation and smooth Work of Breathing performance under the tested conditions at 36 bar.

Formally attesting to the campaign outcome was RINA—a leading international classification and certification body—represented by Daniele Paganelli, who independently witnessed the D-ONE Reclaim trials under official RINA witness certification of the testing process and results.

Underlying D-ONE’s performance is DRASS’s fully integrated engineering approach, with proprietary technologies developed in-house specifically for reclaim and saturation diving, including patented valve technology, dedicated regulator design and an integrated gas-management architecture.
Verification at 350 msw represents an important milestone within our ongoing programme of helmet performance optimisation against the industry’s most rigorous benchmarks.
Together, D-ONE Air, D-ONE Plus for contaminated-water operations, and D-ONE Reclaim form a family of professional-grade, application-specific diving helmet solutions.
