Pressure Tolerant Electronics
Pressure tolerant electronics (PTE) have many advantages over the conventional atmospheric pressure housing. Some of benefits of Pressure Tolerant Electronics are:
 Allows designing systems capable of operations to full ocean depth without the need for expensive atmospheric housings and high-pressure electrical connectors
Improved heat dissipation
No implodable volumes
Flexibility in housing material, shape and design
Reduced Mean Time To Repair from faster access and reassembly of the housing
Phoenix realized the benefits of pressure tolerant electronics in 1999 and has a history of using PTE starting with Remora II during the successful search for the lost Israeli submarine DAKAR in the Mediterranean Sea. Phoenix has since used pressure tolerant electronics in many projects including its fleet of xBOT vehicles and 4 deep water work class ROV’s all of which are rated to 6000m.
Over the years Phoenix has studied the effects of pressure on hundreds of electronic components and built a database which is drawn upon for new pressure tolerant projects. The pressure testing profile used screens for infant mortalities, prior to long term testing.
Through the years of testing Phoenix has demonstrated the long-term effects of high pressure on carefully selected electronic components does not affect their reliability.
Phoenix has conducted many successful deep water missions with PTE vehicles such as xBot’s exploring inside the Titanic and documenting the bridge of the oil rig Deepwater Horizon.
