Danfoss Semco - Marine Fire-Fighting Equipment

Danfoss Semco has the experience and technological knowledge to provide you with fixed fire-fighting solutions using high and low pressure carbon dioxide (CO2), foam, dry chemical powder and high-pressure water mist.

The systems are designed in accordance with IMO / SOLAS regulations and recognised by all leading classification societies and national authorities. Our team specialises in meeting your specifications, no matter how exact, to supply precisely the system you need.

SEM-SAFE WATER MIST FIRE-FIGHTING SYSTEM

The Sem-Safe water mist system is unique. Water is forced through micro-nozzles at very high pressure to create a water mist with the most effective fire-fighting drop size distribution. The extinguishing effects give optimum protection by cooling due to the expansion of water by approximately 1,700 times when it evaporates.

The Sem-Safe water mist system fire-fighting system both provides better protection for personnel and surroundings and minimises potential water damage, because the majority of the water mist evaporates.

The Sem-Safe water mist system is available for accommodation, total flooding, local application and deep-fat fryers.

CO2 FIRE-FIGHTING SYSTEMS

CO2 fire-fighting systems are used as total flooding systems in engine rooms, machinery spaces and cargo holds. The high-pressure system consists of a number of CO2 cylinders, whose outlets are connected to a common manifold.

From there, the CO2 is directed, via selector valves, into various protected spaces. If the protected space is large, a high number of cylinders are required.

These can be replaced by a single CO2 tank, saving approximately 50% in weight and installation costs. The tank contains CO2 cooled to -18°C. The tank, refrigerators, distribution valves, controls, etc. are supplied pre-wired and ready-assembled on a steel frame.

FOAM FIRE-EXTINGUISHING SYSTEMS

Foam used in fire protection is an aggregate of air-filled bubbles formed from aqueous solutions, and is of lower density than the lightest flammable liquids. It is mainly used to form a coherent floating blanket on flammable and combustible liquids to prevent or extinguish fires by excluding air and cooling the fuel.

It then prevents re-ignition by suppressing the formation of flammable vapours, and also adheres to the surface, providing a degree of exposure protection from adjacent fires. Foam can be used as a fire prevention, control or extinguishing agent for flammable liquid in tanks or processing area.

DRY CHEMICAL POWDER FIRE-EXTINGUISHING SYSTEMS

When introduced directly to a fire, dry chemical powder extinguishes flames almost immediately. Dry chemical powder is intended for use in extinguishing fires involving bulk chemical agents and liquefied gases. Our dry systems are developed to meet the increasing demand for large-capacity systems for the protection of ships carrying LNG / LPG and certain chemicals or agents in bulk.

MARINE INDUSTRY QUALIFICATION TESTED AND APPROVED

We operate a QA system in accordance with EN ISO 9001:2000, and we are certified by DNV. Our on-going internal training programmes make our employees, sales engineers, project managers, service engineers and all support staff fully-qualified to handle all our fire-fighting systems for the marine industry.

STRONG FIRE-FIGHTING EXPERIENCE

Danfoss Semco Fire Fighting was formed from two worldwide industrial leaders in fire-fighting: Danfoss and Semco Maritime.

The fire-fighting division of Semco Maritime has over 50 years of experience in the design, engineering and delivery of a variety of fixed fire-fighting systems for demanding marine and offshore industries. Throughout this time, Danfoss has developed and delivered the key components for the high-tech water mist systems engineered by Semco.

The merger was a natural way to combine and further develop the products, skills and knowledge of the two companies. Today Danfoss Semco is a fully-integrated part of the Danfoss Group.
