APM (Atmosphere Protection Module)

Protecting your crew in high-risk areas

The Analox APM (Atmosphere Protection Module) is a configurable modular system which has the ability to monitor up to 2 gasses. This unique solution can be used as a stand alone atmosphere monitor or it can be integrated into existing PMS systems. 

There are currently 3 versions of the APM available, with more configurations to come in the future.

Key Features

  • Flexible to meet your specific needs and ensures you meet current legislation
  • Measures up to 2 gasses with a choice of; O2 (oxygen), CO2 (carbon dioxide) and R134a (refrigerants). The APM will soon be able to measure VOCs (volatile organic compounds)
  • Uses MODBUS RTU communications protocol
  • Temperature compensated sensors with PressureSync technology
  • Fitted with 2 relays
  • Compatible with the Analox Distributed Atmosphere Monitoring solution (DAMS)

Industries that use the APM for atmosphere monitoring

Whether you find yourself on the surface of the sea or way under it, you require continuous, reliable atmosphere monitoring to ensure safety of all those onboard. 

Already the premier gas monitoring and safety source for the defense community worldwide, Analox Group has recently launched the APM (Atmosphere Protection Module) providing submariners with an easy and effective way to monitor up to 2 gasses which offer immediate local notification of gas hazards with the built in option for remote notifications.

Gas monitoring with the APM

The Analox Team of engineers understand the challenges for our defense customers along with the various compliances we must adhere to.

The APM has been designed utilizing all of this knowledge and to ensure it offers life saving accuracy, notifying the crew in the immediate area of hazards, helping to protect their safety.

Tailored Gas Safety Solution

The APM is a highly adaptable system designed to cater for your unique requirements. Analox engineers have future-proofed the design, ensuring it will remain compliant even as regulations evolve. Whether it operates as a standalone unit or seamlessly integrates with a platform management system (like the Analox DAMS), the APM swiftly detects gas hazards in the vicinity empowering the crew to take immediate action.

User maintainable

With the APM, maintenance is in your hands, right in your own country or specified location, meaning you will benefit from minimal downtime and significant cost savings. Analox offers comprehensive training courses for APM maintenance, ensuring you are well-versed in the unit operation and care. This keeps your system at peak performance throughout its lifetime.

Temperature compensated sensors

The APM has been designed to be a trusted solution for submarines and surface ships, operating in temperatures from 0°C to +45°C (+32°F to +113°F). Equipped with Pressure Sync temperature-compensated sensors, rest assured that your Analox APM won’t trigger false alarms, no matter how the onboard temperature or pressure fluctuates. 

Local sensor notifications

The APM has been designed to be used as a stand alone system and its integrated displays serve as a crucial safety feature. These displays deliver real-time notifications to the crew in the immediate vicinity, enhancing safety and minimizing response times when it comes to tackling gas hazards, This localized information not only safeguards those on board but also enables swifter and more efficient actions to eliminate potential gas risks.
