Asserting Power: Submarine Forces and Nuclear Deterrence
As geopolitical tensions rise, submarines are proving essential to preserving sovereignty at sea. They protect exclusive economic zones, strengthen deterrence, gather critical strategic intelligence, and play a key role in joint operations. Dominating the oceans, they project a nation’s military power through precision strikes and vital support for surface forces. Listening without being heard, observing without being seen: these impressive and stealthy submarines are ultra-sophisticated defense assets. Armed with state-of-the-art systems, an expert crew, and unwavering logistical support, they master the depths and conduct flawless operations. As technological marvels, they are the flagship of the naval industry.
For over 140 years, Axima Marine and Noske-Kaeser have been equipping more than 25 navies worldwide with systems HVAC & Refrigeration, CBRN, and fire safety, designed to integrate into the confined spaces and harsh climatic conditions of submarines. The reliability and effectiveness of these systems are essential to ensuring mission success and crew safety at sea, while protecting sensitive equipment.

Our Turnkey Solutions
Axima Marine and Noske-Kaeser have extensive experience in providing solutions for HVAC, Refrigeration, CBRN, and fire safety, for submariners and governments around the world. We have delivered specialized systems for various types of submarines, regardless of their propulsion systems: diesel, electric, or nuclear propulsion…
Withstanding pressure, limiting noise and vibrations, optimizing weight and size, or minimizing acoustic and magnetic signatures—no matter how diverse your requirements may be, our systems adapt to your needs. Our experience, combined with our engineering capabilities and manufacturing workshops allow us to work flexibly and offer you turnkey and custom-designed technologies. We also have facilities for testing and qualification, which also guarantee the performance of our equipment. Furthermore, energy optimization is crucial—particularly for diesel-powered submarines—to reduce dependence on batteries and avoid having to surface frequently, which could compromise the mission. An efficient HVAC system is essential for extending endurance.
Our global presence allows us to offer you maintenance services and management of your spare parts and the retrofitting of your systems HVAC & Refrigeration, CBRN and fire safety on board.
We offer our clients support in finding turnkey and custom solutions.
Flagship solutions and products that combine performance, durability, and safety for your submarines
Supply of dedicated, standalone air conditioners for equipment located in the engine room. The air conditioners are designed to meet the ship’s requirements (shock resistance, durability, low vibration and noise levels, compact size, AC/DC power supply, etc.)
Supply of all available fire suppression systems (CO2, high-pressure water mist, etc.) specifically adapted and optimized for each submarine. Supply of the NITREX fire suppression system (a nitrogen-based fire suppression system specially developed by our company). NITREX is specifically designed for submarines, engine rooms, and battery rooms. Flexibility as a fire suppressant: pure nitrogen is harmless to people and the atmosphere.
Supply of optimized chilled water units tailored to the performance requirements on board. Chilled water is used to cool heating, ventilation, and air conditioning (HVAC) systems, as well as electronic and weapon systems. Use of an environmentally friendly refrigerant. Exclusive and specialized design of condensers/receivers and evaporators. Chilled water and seawater pumps are integrated into the unit. The chilled water systems are designed to meet the specific requirements of ships (impact resistance, low vibration and noise levels, compact size, power supply, redundancy, EMC, etc.).
HVAC equipment is designed and tailored to the specific requirements of the room. The HVAC equipment ensures operational availability through optimal climate control under the ship’s operating conditions (shocks, low vibration and acoustic signature, compact size, power supply, etc.).
We manufacture custom electrical panels and control panels that provide you with a quick and comprehensive overview of the various systems on board.The equipment is designed to meet the specific requirements of ships (impact resistance, low vibration and noise levels, compact size, AC/DC power supply, EMC, etc.). The equipment ensures safe operations.
Supply of refrigeration systems and evaporators specially designed to optimize performance and hygiene. The refrigeration system ensures an adequate supply of provisions for the crew during short- or long-term operations. The refrigeration systems and evaporators are designed to meet the specific requirements of ships (impact resistance, low vibration and noise levels, compact size, AC/DC power supply, redundancy, etc.). The system supplies the standard refrigeration room as well as the kitchen refrigerators. It uses an environmentally friendly refrigerant.
HVAC and ventilation units designed for kitchen equipment with specialized filtration (activated carbon filter).
Central or individual air conditioning units designed to be quiet, ensuring optimal climate control under the demanding conditions found on ships (shocks, low vibration and noise levels, compact size, AC/DC power supply, etc.).
