Ventilation modules are mobile air-conditioned rooms and serve to simplify installation on naval vessels starting with frigate size. The customized designed ventilation modules of ENGIE Axima enable the construction and the installation of many system and plant components such as CBRN protection unit, high-pressure ventilator, air conditioning and sanitary device in a compact container
measuring 12 m3.
Air conditioning units
ENGIE Axima has developed an innovative product line complying with the highest international standards, such as for example VDI 6022, STD as well as BV. Thanks to their special design, our air conditioning systems are very compact and reduced in weight.
Safe operation of systems within the engine rooms is essential for the proper manoeuvrability of the vessel. To ensure this central function, the systems of ENGIE Axima air-condition engine rooms depending on the requirement via seawater or ventilate them with atmospheric and filtered outside air. Via CFD analyses heat pockets can be localized and with it, high surface temperatures can be prevented.
Fan coil units
ENGIE Axima has developed compact fan coil units specially for the use in technical rooms, displaying a high performance at low airborne and structure-borne sound levels. With it, in rooms such as the CIC, high thermal loads can be absorbed efficiently and at minimal space requirements.
Axial, radial, high-pressure fans
Ventilators are used for the ventilation of engine rooms, control centers, sanitary rooms, ammunition storage and many other rooms. To this extent, ENGIE Axima produces high-strength, shock-resistant and vibration-proof axial, radial and high-pressure fans made of extremely lightweight aluminium. Our highly efficient fans are also suitable for use in explosion-proof rooms.
The latest development of ENGIE Axima in the area of CBRN combines the advantages of proven predecessors SLG and SLM and goes even further: The new CBRNflex3600 integrates all components of a full CBRN system in a compact station and allows filtering of up to 3,600 m3/h fresh air. The system provides high connectivity to the existing ship systems, improves the flexibility, saves space, is low maintenance, cost-effective and requires less installation time on board.
CBRN protection unit, door station
Our CBRN protection units reliably ensure the safety of your ship’s crew in case of chemical, biological, radiological and nuclear warfare agent use. With compact door stations of type SLG TpN, ENGIE Axima has developed a CBRN protection unit that has been in use successfully for decades on surface vessels of various naval forces. With an air volume of 300 to 900 m3/h, our stations may be combined in any order and according to your requirements on board.
CBRN protection unit, modular system
Especially for smaller vessels (< 90 m) such as corvettes, space-saving CBRN protection units are essential. Despite its compact form, the modular SLM system by ENGIE Axima clears air volumes between 300 and 3,600 m3h of CBRN warfare agents quickly and efficiently.
Pressure wave protection
Pressure blows caused by detonations at sea may have massive impacts on the vessel during naval missions. Not least, this also affects the equipment and systems on board. With a specially developed pressure wave protection system, ENGIE Axima protects the CBRN protection unit directly after the sand filter and the water trap against damage and thus ensures a long service life.
For operation close to desert regions, protection against sand and dust is essential. ENGIE Axima offers a sand and/or sand water separator combination depending on the type of application in order to protect the CBRN protection unit as well as the subsequent ventilation systems. The filters are primarily made from coated aluminium, and may also be protected against infrared rays by being camouflaged.
CBRN prewetting systems
The CBRN prewetting system is used to wet all outside surfaces of the vessel with seawater. This prevents warfare agents from depositing on the upper deck. In this case, the system is fed by the central fire-extinguishing system. ENGIE Axima offers a multitude of nozzle types for all deck surfaces, walls and equipment.
Provision cooling systems
Whether for small units with two rooms or for ten or more refrigeration rooms, ENGIE Axima offers individual provision cooling systems for your special type of application - also in a shock-resistant and vibration-proof design.
Chilled water units
Chilled water units on board of naval vessels are not only relevant for the operational capability of air conditioning and ventilation systems but are also crucial for the cooling of electronics and weapons systems. ENGIE Axima offers individually designed water chillers with piston or screw compressors in a shock-resistant and vibration-proof design. Also special versions such as compact low-magnetic water chillers are part of our comprehensive portfolio.”
ENGIE Axima offers a diverse range of fire-extinguishing systems using water as an extinguishing agent. Be it hydrant, sprinkler, low-pressure or high-pressure water mist systems, ENGIE Axima designs, manufactures and installs individually designed fire-extinguishing systems for the main fire-extinguishing system as well as for enclosures of engines and energy generators.
ENGIE Axima offers the complete range of CO2 fire-extinguishing systems for the use on naval vessels. In unmanned rooms and enclosures of engines and energy generators CO2-based automated fire-extinguishing systems are used. Antimagnetic versions are also available for special requirements.
Foam systems use seawater and synthetic foaming agents and are primarily used to extinguish liquid fires. The space-saving foam systems by ENGIE Axima are fed by a compact pump unit, comprising one or two foaming agent pumps, a foaming agent container, a pump control cabinet as well as all required valves.
With the development of the worldwide unique HyFEx® system, ENGIE Axima has set a new standard for firefighting in naval shipbuilding. The high cooling effect and the capability to completely extinguish fire also in damaged structures make the HyFEx® system an ideal solution. The German Navy also trusts in our innovative technology. ENGIE Axima HyFEx® systems have a GL type approval and are shock and vibration tested according to BV 0430.
The ENGIE Axima KiFEx® system is a combination of firefighting and fire alarm system in the galley area, specially designed for the use on naval vessels. Integrated flame detectors provide a pre-alarm, and the KiFEx® system is activated by ways of a pneumatic trigger system. By means of the pneumatic system, the resistance of the system is increased and maintenance efforts are reduced.
ENGIE Axima designs, delivers and installs pipe systems for any type of on-board operation systems. In this regard, we are able to process different materials depending on the type of medium to be fed. ENGIE Axima provides specially qualified personnel to execute such work and has the required permits for welding on board of naval vessels.
Pressure holding systems
For the water systems used on board, ENGIE Axima offers a pressure holding system according to your requirements. The reservoirs are designed and manufactured by ENGIE Axima. In addition, we have the required permit for the welding of pressure tanks.
The ENGIE Axima ammunition spray system is used in case of fire in adjacent rooms to cool ammunition storage on board of naval vessels. In case of fire, the ammunition spray system is automatically triggered and this way is able to cool ceilings and walls with substantial amounts of water. Usually, the system is fed by fire-extinguishing systems.
ENGIE Axima manufactures custom-tailored switchboards and control systems with which you will be able to gain a quick and comprehensive overview of our different systems on board. All control cabinets are manufactured pursuant to the requirements according to standards and provisions of the international classification societies DNV, GL, LR, BV as well as the VDE testing and certification institute. For the use on naval vessels and submarines, the control cabinets are delivered in a shock-resistant and vibration-proof design.
The ENGIE Axima switchboards and control systems can be equipped with an SPC and a touch panel for operation and detailed fault display. A visualization of the respective system as well as the operation and control may also be carried out with one or several remote control panel. An interface to the superordinate control systems of the vessel is provided to control our systems.
In the past 35 years, ENGIE Axima has equipped more than 100 surface vessels with its first-class products in the areas of air conditioning/ventilation, CBRN protection, refrigeration technology and fire protection. Our list of references will provide you with an overview of the numerous commissioned projects we have successfully realized.
