Marine compressed air refers to compressed air systems specifically used on ships and offshore installations. Air is compressed by onboard compressors and stored in high-pressure air receivers. It is an essential utility on vessels, providing energy for starting engines, operating control systems, and supporting various mechanical and safety functions. These systems are designed to be reliable, moisture-free, and capable of operating in harsh marine environments.

Because many applications are critical, compressed air has to be sufficient, clean and without contaminants.

Applications:
Marine compressed air is used in several critical shipboard operations:

Main engine starting: High-pressure air (typically 20–30 bar) is used to start large diesel engines
Auxiliary engine starting: Supplies air for starting generators
Control and automation systems: Operates pneumatic valves and instrumentation systems
Service air: Used for cleaning, tools, and general maintenance tasks
Safety systems: Supplies air for emergency shutdowns and alarms
Whistle and signaling systems: Operates the ship’s horn
Ballast and tank operations: Assists in tank cleaning and fluid handling processes

Sigma Hellas provides a wide range of compressed air and compressed gas sensors / systems for continuous on-line monitoring such as dew point sensors, oil content sensors, particulate sensors, flow meters, leak detectors etc.
