PLUS POD FOR AIR DIVING IN CONTAMINATED/POLLUTED WATERS
D-ONE PLUS Pod, interchangeable with D-ONE Air Pod, comes in stainless steel and titanium and is designed for air diving in contaminated/polluted waters. Its robust Gas Reclaim Back Pressure Regulator valve enables the recovery of exhaled Heliox mixture during saturation dives to 400msw.
D-ONE diving helmet is innovatively modular, granting one helmet shell to be seamlessly adaptable to various diving environments thanks to its dive-specific pods.
Gas Reclaim Valve: 0.5 Kg lighter compared to other commercial valves;
Optimized breathing effort: Perfect synergy of its critical elements ensures smooth breathing and maximized gas reclaim at any depth;
Titanium Flow-Disc: Lightweight and durable. Allows easy access to the inner valve area;
Efficiency: Flow-Disc configurations specific to each working depth for maximum gas recovery on every dive;
Intuitive placement: Reclaim Isolation and Emergency Valves positioned at same height for convenient reach;
Seamless Ball-Valve installation: Mirroring diving helmet for simplicity;
Easy removal of dirt and debris, unlike other commercial valves on the market;
Maintenance in 15-minutes using standard tools. No special tools required.
The New Generation of Commercial Diving Helmet
D-ONE has been designed around the concept of modularity: One helmet shell to suit varying dive environments by means of interchangeable pods:
• Standard Pod for Air Diving
• Reclaim Pod for Air Diving in polluted/contaminated waters
• Rebreather & Reclaim Pod
For diving in contaminated waters, the helmet can be configured with a reclaim valve that prevents contact of the valve with polluted water. Coupled with a dry-suit and water shroud, the diver is effectively sealed off and protected from the surrounding environment
Incorporating the latest smart technology for increased safety, ergonomics and functionality, features unique
to D-ONE include:
Same shell reconfigured as Air, Reclaim or Rebreather by means of interchangeable pods
Wide-angled viewport for increased field of vision
30° rear-angled ergonomic design allowing upward-tilting neck motion
Anti-flood fail-safe donning, sealing & removal
Polyurethane gaskets for premium durability in the saline environment
Balanced Demand Regulator for smooth breathing
Integrated welding shield/hot water shroud/defogger
Integrated video camera & light
DRASS-patented remote diver monitoring for real-time tracking of breathing patterns, bail-out pressure, depth & inclination
Optimized spare parts for easy, safe maintenance

Camera
Compact and slim PAL video camera module, completed with a connectorized cable (Wetcon MCIL-4M), ready to be installed on top of Drass D-ONE diving helmet. It is the perfect companion of the helmet light. Maximum depth 300 msw. The camera features a high-resolution module with 850 TV lines in PAL standard (CVBS); the internal CCD sensor is a full-featured 1.3 Mpixel Sony: WDR (Wide Dynamic Range), 2D-DNR (Dynamic Noise Reduction), digital day&night. The CCD module has been specifically selected to ensure the best possible performances in diving activities, with low and uneven light levels. FOV (Field of View) is 90° in air and 80° in water. The camera is made with black anodized aluminum, and it has very limited dimensions: 147 mm length, 70 mm wide and only 50 mm height; moreover, the camera body is bent on the left so to perfectly align with the eyeline of the diver when installed on the D-ONE. Power supply is 24 Vdc, current consumption 80 mA @ 24 Vdc (2 W). To obtain the best signal quality, it is recommended to use a cable with 2xSTP, especially when the camera is used in conjunction with dimmable lights or other electromagnetically noisy devices – maximum recommended connection cable length is 100 meters. Each camera has its own SN and is subject to a complete FAT (functional test and pressure test at 47 bar) before delivery or installation on the helmet
Light
Compact and slim light module, completed with a connectorized cable (Wetcon MCIL-2M), ready to be installed on top of the Drass D-ONE diving helmet. It is the ideal companion for the helmet camera. Maximum depth 300 msw. The core of the light is a new high performance, round led cluster including 4 cool white leds, delivering a total of 940 lumens at full power. Color temperature Is cold white (5650 K typical). The led cluster is completed with a circular narrow beam optic with 10° aperture, capable to increase by more than 10 times the light intensity of the beam, so to be able to light even far spots - 4000 lux @ 1m typical intensity. The led cluster is supplied by and internal driver, which can be powered directly with a continuous 24 Vdc for maximum power (typical power 10W), or with a dimmed power to be able to control the light intensity from 0% to 100%. This is possible thanks to the capability of the driver to be controlled by means of PWM signals (Pulse-Width Modulation) in CV Mode (Constant Voltage) – ask Drass for details. The light is made with black anodized aluminum, and it has very limited dimensions: 143 mm length, 70 mm wide and only 50 mm height; moreover, the camera body is bent on the right so to perfectly align with the eyeline of the diver when installed on the D-ONE. Each light has its own SN and is subject to a complete FAT (functional test and pressure test at 47 bar) before delivery or installation on the helmet.
