Info:
Fire flaps are a necessary requirement for any commercial in-survey vessel, and are also a good idea on non survey craft. Fire flaps are either triggered automatically or manually, and effectively close the air supply to the engine room to allow fire suppression equipment to work.
We can manufacture and supply Fire Flaps (or Air Dampers) either in conjuction with our intake grilles, or supplied on their own. They can be mounted immediatly rear of the grilles, within the ductwork itself, on the bulkhead or deck head penetration, or any penetration that serves air in or out of the engine room.
Our Fire Flaps come with a control cable that runs from the Fire Flap to an external location outside of the engine room space. This Manual Control is easily opperated by disengaging the pull ring from the keeper bracket. This action trips the spring loaded damper louvre which closes off the air supply to your engine room. They also have a Semi Auto Control. If there is fire or intense heat in the vacinity of the control cable (which is a synthetic material), the cable will melt and trigger the flap automatically.
If you use a Fire Flap system, you will need to test and prove the system annually for a surveyor. To reset after this test simply repull the cable and re-engage the ring into the keeper bracker. Its very easy.
Manufactured to size and shape. No solenoids or electonics required. Could be easily installed by an owner operator. Manual or Automatic release. Easy to reset after testing. Can be supplied singly or in conjuction with air intake grilles.
Directional Air Diverters:
Adjustable air diverters are Fire Flaps (Air Dampers) that are manufactured in a format designed to fit directly on to the dischage side of the engine room fans. These Air Diverters fit on the rear side of the fan (eng room side) making it possible to use the fire flap as adjustable air director. For example direct the incoming air at a generator, or possibly a dead spot in the engine room that requires greater air movement.
To install these air diverters, first assess air direction, and then setup control cable to suit this situation.
