For over 35 years, Fireboy has been the most trusted name in on-board
clean agent fire protection.
Fireboy fire systems are specifically designed for protecting enclosures
up to 17,300 cubic feet / 500 cubic meter, such as engine rooms on
boats.
FES System
An engineered system utilizing a fixed nozzle agent distribution
network, the system is designed and installed in
accordance with the IMO FSS CODE (SOLAS, IMO MSC/ Circ.1267 "Clean Agent
Fire Extinguishing Systems").
When properly designed, the HFC-227ea fire extinguishant system will
suppress surface burning fire in Class A, B, and C hazards.
80% of
HFC-227ea fire extinguishant fire fighting effectiveness is achieved
through heat absorption and 20% through direct chemical means (action of
the fluorine radical on the chain reaction of a flame.
Complete suppression using HFC-227ea fire extinguishant has the
following advantages:
The low concentration of
HFC-227ea fire extinguishant required means less visual obscurity
and minimal risk to personnel.
The small quantity of agent discharged minimizes over-pressurization
of the protected area.
Maximum
safety for personnel due to low toxicity.
The ability to prevent re-ignition as long as concentration levels
are maintained.
System Operation
The system consists of extinguishing agent stored in high strength steel
cylinders. Manual or automatic actuators release the agent into the
protected space. The agent is distributed and discharged into the
protected space through fixed piping and nozzles.
Each nozzle is designed to deliver a uniform discharge of agent into the
protected area. For large protected spaces, cylinders can be manifolded
together. The cylinders are connected to the manifold by means of a
flexible discharge bend and check valve.
Cylinders can be mounted internally or externally of the protected
space.
Agent Tank
The agent storage tank consists of an approved DOT or CE-TPED high
pressure steel tank filled with a valve and internal siphon tube,
factory filled with HFC-227ea fire extinguishant, and super-pressurized
with dry nitrogen to 360 psi (25 bar) at 70 °F (21 °C). Tanks
sharing the same manifold shall be equal in size and fill density.
Tanks are available in 8 Sizes, ranging from 8 litre to 343 litre.
A nameplate is adhered to the tank displaying the agent weight, tare
weight, gross weight fill density, and charge date. On the larger size
tanks, an optional liquid level indicator is available.
Agent - HFC-227ea fire extinguishant
A clean, gaseous agent containing no particles or oily residues. It is
produced under ISO 9002 guidelines to strict manufacturing
specifications ensuring product purity.
HFC-227ea fire extinguishant
leaves no residue or oily deposits on delicate electronic equipment, and
can be removed from the protected space by ventilation.
Distribution Piping Network
HFC-227ea fire extinguishant engineered systems are based on a Hydraulic
Flow Program developed by Hughes Associates Inc. The program
predicts the two-phase flow of the agent and nitrogen through a pipe
network. Information detailing the enclosure is entered and the program
calculates the required pipe sizes, nozzle drill sizes, average nozzle
pressures, and discharge time.
As system design calculations are critical to the success of the
extinguishing system, only
Fireboy-Xintex Inc or Fireboy-Xintex
Ltd trained personnel are permitted to perform system calculations.
Nozzles
HFC-227ea fire extinguishant is distributed within the protected area by
the discharge nozzle which is sized to ensure the correct flow of agent
for the hazard. Nozzles are available with seven or eight ports to
allow for either 180° or 360° horizontal discharge patterns. Ports
are drilled in .004 inch (0.1 mm) increments to the specified system
design. Nozzles are supplied In brass with NPT threads.
Nozzles are available in 6 sizes, ranging from 3/8 inch to 2 inch.
