FM – 200 (HFC – 227ea) Clean Agent Fire Supressions Systems

AKRONEX Inc. SYSTEMS OF AUTOMATIC GAS FIRE EXTINGUISHING
ACTIVITY AND SERVICES

AKRONEX Inc.  is engineering and manufacturing company that operates on gas fire suppression systems
We recommend usage of automatic fire extinguishing systems especially in the data centers, telecommunication centers, electrical rooms, archives, museums, rooms with medical systems.

Automatic gas fire extinguishing systems don’t harm the people health, don’t influence to environment, no post-fire residue or clean up, and electrically non conductive. Thanks to these qualities they are widely used in areas with valuable equipments. According to the Montreal treaty (1994), Halon 1301, which was sold in our country for many years, was changed by alternative to him clean gas extinguishing systems. Filling and refill of cylinders with gas HFC-227ea (known as FM200), which is widespread in Turkey, has been deficit for many years.

SERVICES
Design of fire extinguishing agents HFC-227ea and NOVEC 1230 complies with the standards NFPA 2001 and ISO 14520,
Pipeline layout by approved hydraulic calculations of UL, definition of nozzles
Preparation of AutoCAD and isometric drawings,
Preparation of gas cylinders and original equipment in sufficient quantity,
Refilling of cylinders and replacement of spare parts if it is necessary,
Turnkey installation of gas fire extinguishing systems, providing periodic maintenance

 

HFC-227 ea (FM200) IS AN ALTERNATIVE TO THE MOST WIDELY USED HALON
Discharge: 10 seconds
No post fire residue or clean up
Is electrically non-conductive
No damage to protected equipment
ODP=0 (ozone depletion potential is zero)
Standards: ISO 14520, UNE 23571 and NFPA 2001
HFC-227 ea is a clean agent and approved as alternative to Halon 1301. HFC-227ea or its chemical name – heptafluoropropane (CF1301 CHFCF3) is ideal for protecting a lot of places where previously used Halon 1301. HFC-227 (odorless and colorless) doesn’t conduct electricity, that’s why it is an effective tool for protecting computer rooms with electrical risk, as well as telecommunication centers, archives, museums and similar facilities with valuable materials. Moreover, this gas is suitable for fires both class AB and class A.

 

The tests carried out in accordance with NFPA 2001 show that HFC 227-ea has no serious effects to human health when human body contacts with it for 5 minutes, even when the gas concentration reaches 10% w/v. This test shows once more that HFC 227-ea is absolutely nonthreatening for human health. HFC 227-ea extinguishes the fire, reducing it physically -and absorbing heat. One and/or more discharged cylinders of HFC 227-ea ensures the safety of people and minimize the possible damage of valuable materials and structures by rapidly extinguishing fire.

 

HFC 227-ea systems are designed so that the period of discharge lasts only 10 seconds.
The design concentration for fires of class A is 7 % and the duration of discharge is 10 seconds.
HFC 227-ea is colorless, odorless and not conducting electricity. It extinguishes fire absorbing heat; no post-fire residue or clean up.
Advanced valves allow the control and maintenance of critical components of the valve during commissioning. Thus, prevents unwanted emissions. The valves are approved by UL-FM (USA).
Fire extinguishing system HFC 227-ea includes nozzles, specially designed for this extinguishing agent. For HFC 227-ea is suitable nozzles 180C and 360C.

There are modular and central (more than one cylinder) systems. In modular systems, cylinders are mounted near the protected area. Central system allows protection of several areas at once, installing a group of cylinders and valves in selected areas, if it is necessary.
The quality control system of AKRONEX Inc. controls all the components used in the fire suppression system.

 

HOW DOES WORK THE AUTOMATIC CLEAN GAS FIRE EXTINGUISHING SYSTEM?

Detectors, mounted in the protected zones (room, suspended ceiling, and raised floor) detect fire and send warning alarm to control panel. When control panel receive a signal from zone 1 it gives sound pre alarm warns. When signal send from zone 2 it makes audible and visual pre-alarm warning. When control panel detects a fire by fire scenario you can make some actions or stop the process as you will. Ventilation equipments system will turned off, fire alarm will triggered, UPS will turned off and extinguishing agent will be discharged into protected zone. Fire extinguishing gas is stored in special cylinders for storage. The gas passes through pipelines and discharges into protected zone through nozzles. Concentration of discharged gas will be enough to extinguish a fire within 10 seconds.
