The Deck Purge Box in combination with a self-sealing purge port and pressure cap is an alternative concept for removing moisture from deep sea housings, both spheres and cylinders.
The integrated system creates a vacuum inside the deep sea housing. That same vacuum is used to draw air back into the sphere, forced to pass through a drying desiccant cartridge. After a few cycles, the interior air is dry below any dew point possible in the cold ocean depths, making certain all electronics or cameras will not have condensation on them. |
Pressure Activated Switches are available in a number of configurations, for installation in spheres, endcaps, PBOF housings, and In-line on a pigtail.
Titanium body models trigger at 20-30m, and tolerate overpressure to 12,000m. Each switch is individually serialized and tested for switching function and pressure tolerance, then re-checked for switching function after the pressure test. A certification of performance is supplied with each switch. |
