Blue Robotics

Blue Robotics’ new aluminum tubes for the 3 Series and 4 Series Wa- tertight Enclosures now offer greater depth ratings, better heat transfer to the water and a hard anodized black ? nish, according to the manufacturer

Both tubes are bored out from the inside for optimal wall thickness and to reduce the enclosure weight. The 3 Series tube is rated for 500 meters (1640 ft) and the 4 Series is rated for 400 meters (1312 ft).

Develogic develogic subsea systems offers a wide range of pressure housings, in- cluding off the shelf standard and customized designs. One of the compa- ny’s specialties is the design of housings with integrated optical compo- nents including large ? at and dome shaped viewports with depth ratings down to 20,000 psi. It is able to manufacture in house subsea housings up to 500mm in diameter and 2,000mm length in all common materials with a focus on Titanium Grade 5. Quality control is supported by vibration, temperature and pressure testing facilities (up to 14,500psi).
