What is a Breathing Gas Supply System?

A class-aligned, independent breathing air source for toxic or oxygen-deficient atmospheres — sized for long-duration work with reserved capacity for safe escape.

Offshore operations: tank entries, paint booths, confined spaces, hot work with air-fed masks/SCBA.

Extended campaigns: large bottle banks + dual-stage PRS to stabilize flow/pressure for multiple users.

Safety envelope: gas detection interlock to stop compressor; quality test kit to prevent contamination ingress.

System Architecture

Typical BGS chain and optional add-ons for harsh offshore environments.

HP Compressor (BAUER)

Continuous filling, interlocked to Dräger gas detection.

LW Explosion-proof Charging Cabinet

Safe charging enclosure during bottle fill.

35 MPa Bottle Bank

HP storage racks; relief, gauges, stainless tubing.

Dual-Stage PRS (316L)

No back-pressure risk, stable medium pressure supply.

Airline Distribution

Wall boxes with CEJN quick couplers; user counters.

Personal & Escape

Airline sets + Dräger escape devices with 3 L/30 MPa.

Gas Quality Test Kit

H₂O, oil, CO₂, SO₂, H₂S, NOx, CO — portable box.

CO₂ Scrubber / Condensate

Optional for environmental/ambient challenges.

Refuge Chamber (optional)

Positive pressure room with dedicated PRS manifold.

Docs & Training

P&ID, GA, FAT, O&M, drills and maintenance logs.
