Applications
Nitrogen fire fighting
One of the key lines of the membrane-based
gas separation and production activity is the generation
of gaseous nitrogen from the air flow. Nitrogen is a chemically
inert gas not sustaining burning processes of any hydrocarbon
substances. This makes nitrogen an ideal agent for fire-fighting purposes
with the creation of the oxygen-lacking environment in industrial
facilities. With the oxygen concentration not exceeding 10% the environment
necessary for the burning process ceases to exist. Gaseous fire-fighting
units are exceptionally effective and capable of fire extinguishing
within a few seconds, irrespective of the hot spot
distance. Alongside, they are highly dependable and allow for easy
operation and maintenance. In a number of cases they prove
to be the only type of fire-fighting equipment applicable
in hard-to-reach fire hazards, such as mines, for instance.
Beyond that, GRASYS fire-fighting units can serve as an in-doors source
of inert environment maintaining its constant composition. These and other
unique characteristics and specific advantages ensure the units an ever
broader recognition and expansion across various fields of human activity.
The most recent scientific findings combined with a profound company
specialists experience provide GRASYS fire-fighting equipment with a range
of aparent benefits:
- Zero damage to technological equipment
Unlike the standard foam and water-type systems of fire extinguishing,
nitrogen fire-fighting units cause no damage to the pressures
technological equipment.
- Broad-front fire fighting
Nitrogen fire-fighting units allow for the overall and extensive
fire fighting with its efficiency in no way affected by the distance
or inaccessibility of fire hazard.
- Continuous maintenance of the inert environment
Nitrogen fire-fighting units are designed so as to allow
for maintaining a steady explosion and fire safe composition
of the atmospheric air.
- Optional container design
Nitrogen fire-fighting units can be provided in a containerized
version, mounted on sledges or chasses.
- Complete automation
In case of fire, the unit will automatically start delivering
nitrogen to the conflagrant space or the technological
vessel alight.
- Easy operation
Company units have significantly low operation and maintenance requirements.
The fire extinguishing and the receiver replenishing systems
are unmanned and require no direct operation.
- Zero reloading requirements
In contrast to the traditional fire-fighting systems, GRASYS
units can go without routine reloading. After the unit was used
for the fire-fighting or technological purposes, it starts
automatically to refill the wasted nitrogen.
- Environment safety
Nitrogen is an ecologically-friendly gas and causes no hazardous
environmental impact being used in the nitrogen fire-fighting units.
- Low operation & maintenance costs
Nitrogen is highly efficient under fire-extinguishing applications, where
it is produced solely from the atmospheric air undergoing
processing in the unit. The operational costs are therefore
appear to be a highly important factor.
GRASYS fire-fighting units are designed to allow
for a double-mode usage including maintaining a stable atmospheric
composition with the specific maximum allowable oxygen concentration in a closed
space of an object or a technological vessel. Provided that
the burning process is generally impossible in the ambient
with the oxygen concentration below 10% this function helps guarantee
an almost absolute fire and explosion safety. Additionally, the produced
nitrogen can be used for the technological vessels blowing
with the automatic replenishing of nitrogen in the receiver.
