Noske-Kaeser


More than Air Conditioning and Piping

Noske-Kaeser GmbH ranks among the world’s leading suppliers of marine equipment. NAVAL FORCES spoke to the company at its headquarters in Hamburg. Today, Noske-Kaeser GmbH, as an international group of companies, is a global leading supplier of turnkey marine equipment. It provides customised, innovative, and economic solutions in the fields of air-conditioning, ventilation, refrigeration, piping, and firefighting, as well as CBRN protection systems. The company, with numerous references in civil shipbuilding projects – passenger vessels, cruise liners, fast ferries, container vessels, tankers and megayachts – was also able to develop a strong position in the naval business, providing equipment and components for a large number of naval ships around the globe, including submarines. It looks back to more than 130 years of experience, with more than 1,500 air-conditioning and ventilation systems delivered to international customers for use on-board fast patrol boats, frigates, mine-countermeasures vessels, logistics support ships, and submarines.

Jürgen Matthes, CEO of Noske-Kaeser GmbH: “We are looking into the future very positively. We are looking forward to all the projects worldwide which we are realising currently and will undertake in future in the different technological and business areas – [Navies] as well as cargo and passenger shipping, offshore vessels, and substations.”















Proven Ground
Noske-Kaeser’s CEO Jürgen Matthes is balancing the company’s product portfolio while shaping its international business. Research & Development (R&D) is a key instrument to maintain the company’s worldwide leading position in the market, he noted. “Noske-Kaeser annually invests a constant amount of its operating income in [R&D]. These efforts have secured Noske-Kaeser’s leading market position in different fields of firefighting, HVAC [Heating, Ventilation and Air Conditioning], and CRBN protection. We view ourselves as innovation leaders and are constantly working on the development of new and optimised turnkey solutions to suit the special needs of German and international Navies.” There is a high demand for Noske-Kaeser’s expertise in any of these technological fields around the globe. According to the company’s CEO, it has corporations, selling agencies, and service partners in a number of countries, including Australia, India, Malaysia, New Zealand, Turkey, the US, and the United Arab Emirates. “In addition, we are active in countries such as Greece, Poland, Japan and South Korea.” Matthes also said Canada is an important and promising market for Noske-Kaeser. “The Canadian Navy has set up an extensive shipbuilding programme [Canadian Surface Combatant] to which we would like to contribute through our comprehensive expertise and well-proven technologies. We have already been in active dialogue with a couple of Canadian companies regarding our firefighting and HVAC solutions.” According to him, the company is also working on strengthening its position in the Asian market.

The HyFEx extinguishing unit is designed as a total flooding system for machinery rooms and helicopter hangars usually consisting of two HyFEx stations (shown) for each protected room. In these stations, 3% foam (AFFF) is mixed to seawater from the fire main system and is distributed to a separate nozzle-system for each station, covering 50% of the extinguishing volume.

Lead in CBRN Protection Systems 
Two different types of NBC protection air systems are on order: a modular system and a door station. The former (abbreviated SLM) offers a much higher output of protected air; Noske-Kaeser names volumes of 900m³/h, 1800m³/h, 2700m³/h, and 3600m³/h. The maximum capacity of the air intake unit is 1800m³of air per hour. The door station (SLG) consists of a gas-tight aluminium housing and a frame construction made of steel. The company’s brochure says the unit is bolted gas-tightly to the superstructure with a rubber seal. A steel door separates the unit from the outside of the ship, so replacement of the filters and maintenance is carried out from outside through that steel door. When closed, the unit is kept in an overpressure condition by air from the citadel. The gas-tight sealing of the door is achieved through the use of a pneumatic seal, which is kept under pressure by the ships pneumatic air system. The unit works with either two or three compactly designed NATO filters, each capable of filtering coarse and fine particles as well as harmful gases and vapours from chemical warfare agents of an air volume of 300m³/h.


The SLM 900/600N system has the same function as the SLG but is designed as a modular system.

Powerful Firefighting Systems
Noske-Kaeser’s range of firefighting solutions include seawater spray and sprinkler systems, gas and powder fire extinguishers equipment, as well as the HyFEx® system. The latter is the company’s special solution for firefighting for machinery rooms and helicopter hangars. It is found aboard the German Navy’s Type F122, F123, F124, and F125 frigates, Type K130 corvettes, as well as naval ships operated by foreign Navies, including the South African Navy. A most modern and maintenance-free firefighting package has been developed specifically for the German Navy’s Type F125 frigate, NAVAL FORCES learned from Robert Megyery, Head of Engineering, Piping and Firefighting. The package includes a fire extinguishing unit with a sprinkler system for the ship’s crew accommodation, the KiFEx® solution for firefighting purposes in the galley, and two shock-resistant firefighting monitors that can also be used on the landing deck.

Robert Megyery, Head of Engineering, Piping and Firefighting: “The company is looking towards a strong international position in the field of firefighting equipment, namely in the Middle East and the Asia-Pacific Region.”
Interestingly, KiFEx can also be utilised as a non-lethal weapon. “The HyFEx System [Hydro Fire Extinguishing System] was developed by Noske-Kaeser to provide our customers with an effective and harmless alternative to the poisonous CO2 system. HyFEx is the best system to protect machinery spaces and helicopter hangers of Navy vessels”, Noske-Kaeser’s CEO explained. HyFEx-protected compartments are sprayed with 5 litres per m² (min) of a water/foam liquid solution. The purpose of the foaming agent is not to produce foam but to increase the wetting effect particularly in presence of greases, oils, and fuels. Also, the system combines a high cooling effect with a high protection against re-ignition. Noske-Kaeser said helicopter hangars or smaller rooms are normally protected by one single HyFEx station delivering 100% of the extinguishing volume, with each station equipped with an additional connection for a foam branch pipe. It is also possible to connect Noske-Kaeser-provided monitors to a separate HyFEx station for firefighting on a helicopter landing deck. Noske-Kaeser underlined that extinguishing tests proved the effectivity of the system and particularly its advantages in open facilities. Positive tests also showed a good extinguishing result up to a complete air-change within one minute.

The Nitrex nitrogen firefighting system developed for submarines does not result in contamination of the submarine’s atmosphere by extinguishing agents.

Another product is Noske-Kaeser’s Nitrex® system. It is the only nitrogen firefighting system in the world that is designed especially for submarines. Since only pure nitrogen is used as an extinguishing agent, there is no contamination of the submarine’s atmosphere. The whole system was tested by the German Navy in their test facilities. The arrangement of cylinders and valves can be adjusted based on the space and dimensions available inside the submarine. Noske-Kaeser developed both standing and hanging versions of the system to suit all kinds of requirements.
