Environmental Control

JFD provides advanced environmental control equipment designed to meet the unique needs of submarines, ensuring a reliable, stable and controlled atmosphere promoting crew heath and operational effectiveness.

JFD has longstanding experience supporting global Commercial and Defence operations and offers a range of robust and reliable environmental control equipment. Inherent to underwater missions, submarines face some unique challenges managing air quality, temperature and water supply:

Confined Space

Compact, enclosed spaces require meticulous control of air quality and climate. Limited airflow can lead to rapid accumulation of CO2 and other contaminants if not managed effectively. This makes it essential to have reliable CO2 scrubbers and air filtration systems to maintain a breathable atmosphere and prevent discomfort and health issues.

Extended Operations

Submarines often remain submerged for extended periods, requiring systems that can operate continuously without failure. JFD systems are proven to function efficiently over long durations with minimal maintenance and downtime.

High Pressure Conditions

The high pressure environment underwater affects both the design and performance of environmental control systems. Operating across both the Commercial and Defence markets has given JFD unique experience engineering robust systems which can withstand significant pressure variations without compromising functionality.

Temperature Regulation

Maintaining a stable temperature is critical in a submarine, where the external environment can vary widely. Regulating temperature is critical for not only the comfort of the crew, but also for the function of sensitive equipment. JFD systems can effectively manage heat generated by machinery and electronic equipment while maintaining a comfortable living environment.

Humidity Control

High humidity can lead to condensation which can damage equipment and become an uncomfortable environment to live in. JFD systems can help maintain a dry and safe environment.

Water Supply and Waste Management

Providing a continuous fresh water supply and managing waste are significant challenges. JFD Portable Water Systems are compact, efficient and easy to integrate into a submarine’s infrastructure, enabling a reliable clean water supply. Our waste management solutions are able to handle byproducts without compromising the submarine’s environment.

System Integration and Maintenance

JFD systems have proven their reliability and maintainability through operational use onboard defence and commercial vessels over 40 years. We understand maintenance access, service and repair requirements in environments where operations cannot be disrupted.
