DESIGNED WITH THE MISSION IN MIND

The Buoyancy Control System with Acoustic/Timer Actuation (BCS-ATA) is the first easy to use buoyancy control system that enables the active management of payload buoyancy (net positive or net negative) to meet mission objectives. The BCA-ATA provides for system activation by hardwired tablet, acoustic signal or by a pre-programmed timer. The BCS-ATA can be used in demanding applications such as Ordinance recovery, sensitive equipment maintenance and installation. The BCS-ATA can be used in demanding applications such as Ordinance recovery, sensitive equipment maintenance and installation.

  • Each Subsalve product is 100% tested prior to shipping.

Product Details

Active Buoyancy Control
  • An integrated system to control ascent, decent or hover at a user specified rate or depth
  • Fill and buoyancy control valves continuously open and close as needed to deliver setpoints (not possible with pyrotechnic valves)
Mode Control

Autonomous control or continuous monitoring
modes available
Mode can be chosen to meet the needs of the dive plan

Tablet based configuration

Provides ease of training, confirmation of settings and continuous monitoring of depth, rate and bottle pressure when in monitoring mode (user output in hardwired continuous monitoring mode)

Housing and Testing
  • Underwater housing does not need to be opened for normal operation
  • Reduced training time and the confidence that you can confirm settings and status before deployment
  • System can be fully “dry tested” pre-dive
  • Allows for reliable execution of dive plan
User Friendly
  • Proprietary internal valve technology eliminates squib handling and maintenance saving ~ $3000/year in consumables.
  • GPS synchronized calendar or countdown timing allows for selection of actuation time and the ability to schedule multiple units.
  • Innovative Hydrophone mounting mitigates bottom effects extending the effective range in difficult environments.
  • Ergonomic design allows for a single hand operable diver switch
