Affirming your power: underwater forces and nuclear deterrence
In response to increasing geopolitical tensions, submarines are essential to maintain sovereignty over the seas. They protect exclusive economic areas, reinforce deterrence, collect essential strategic intelligence and play a key role in joint allied operations. Dominating the oceans, they project a country's military power thanks to precise strikes and vital support to surface forces. Listening without being heard, observing without being seen: these submarines, impressive and stealthy, are ultra-sophisticated defence resources. Armed with cutting edge systems, with expert crews and unshakable logistics, they control the depths and carry out faultless operations. Packed with the latest technology, they are the flagship of naval industry.
For more than 140 years, Axima Marine and Noske-Kaeser have been equipping more than 25 navies throughout the world with HVAC&R, CBRN, and fire protection systems designed to be integrated into the confined environments and harsh climatic conditions of submarines. The reliability and efficiency of these systems are essential to guarantee the success of the missions and safety of the crews at sea, whilst protecting the sensitive equipment.

AXIMA Marine and Noske-Kaeser Turnkey solutions
Axima Marine and Noske-Kaeser have great experience in the supply of HVAC, Refrigeration, NRBC, and fire protection solutions, for submariners and governments throughout the world. We have delivered specialised systems for a wide range of submarines, whatever their propulsion systems: diesel, electric or nuclear propulsion…
Withstanding the pressure, limiting the noise and the vibrations, optimising the weight and the dimensions and also minimising the acoustic and magnetic signatures, no matter how diverse your requirements, our installations adapt to your needs. Our experience coupled with our design study capacities and manufacturing workshops enable us to work with flexibility, and to offer you turnkey and custom-built technologies. We also have testing and qualification installations, which guarantee the efficient performance of our equipment. Energy optimisation is also crucial, particularly for diesel powered submarines, in order to reduce dependency on the batteries and to avoid having to resurface frequently and therefore compromise the mission. An effective HVAC system is essential to increase range.
Our geographical presence throughout the world enables us to offer you maintenance services, management of your spare parts and upgrades for your HVAC, Refrigeration, NRBC and fire protection systems on board.
We offer our customers advice and support to enable them to obtain turnkey and custom solutions.
Flagship technologies and products combining performance, sustainability and safety for your submarines
Supply of dedicated and independent air-conditioning units dedicated and independent air-conditioning units for equipment located in the engine room. The air conditioners are designed according to the constraints of the ship (shock, resistance, low vibration and sound signature, compact volume, AC/DC power supply, etc.).
Supply of all firefighting systems available (CO², high pressure water mist, etc.) specially adapted and optimised for each submarine. Supply of the NITREX firefighting system (Nitrogen firefighting system specially developed by our company). NITREX is specially designed for submarines, engine rooms and battery compartments. Flexibility as an extinguishing agent: pure nitrogen is inoffensive for humans and for the atmosphere.
Supply of optimised chilled water units adapted to the required performances on board. The cooled water is used to cool the heating, ventilation and air conditioning systems and the electronic and weapon systems. Use of an environmentally friendly coolant fluid. Exclusive, special design of condensers/receptors and evaporators. The cold water and sea water pumps are integrated into the unit. The chilled water units are designed to correspond to the ships’ constraints (shock resistance, low vibratory and acoustic signature, compact volume, power supply, redundancy, EMC, etc.).
The HVAC equipment is designed and adapted to the specific requirements of the room. The HVAC equipment ensure operational availability by optimised climatic control in the conditions and constraints of the ship (shocks, low vibrations and acoustic signature, compact volume, electrical power supply, etc.).
We custom manufacture electrical switchboards and control panels which will allow you to have a quick and comprehensive overview of the different systems on board. The equipment is designed according to the ships’ constraints (shock resistance, low vibratory and noise signature, compact volume, AC/DC power supply, EMC, etc.). The equipment ensures the safety of the operations.
Supply of refrigeration installations and evaporators specially designed to optimise performance and hygiene. The refrigeration installation provides the appropriate supply for the crew during short or long term operations. The refrigeration installations and evaporators are designed to correspond to the ships’ constraints (shock resistance, low vibratory and acoustic signature, compact volume, AC/DC power supply, redundancy, etc.). The system supplies the standard refrigeration room and the refrigerators in the galleys.
Use of environmentally friendly coolant fluid.
HVAC and ventilation units designed for kitchen equipment with specific filtration (activated carbon filter).
Group or individual air conditioners Silent air conditioners to ensure optimal air conditioning under the constraints of ships (shocks, low vibrations and sound signature, compact volume, AC/DC voltage...).
