SAFE227 Fire Extinguishing Systems
HFC227ea is a fire extinguishing agent used in Fire Extinguishing Systems.
It is produced for use in fire protection in hazards where water is not proper to use.
It is widely accepted and respected around the world, as a clean agent respirable extinguishant.
SAFE227 fire extinguishing systems offer exceptionally fast fire protection, reaching extinguishing levels in ten seconds or less. When the systems are installed according to the design standards they extinguish without any damage. No harm on human health observed while systems discharge.
The ability to extinguish a fire this quickly equates to:
● Less or almost no damage
● Lower repair costs during and after fire
● Extra margin of safety for people
● Less downtime and disruption of business
SAFE227 systems extinguish fire successfully where the room integrity can be provided. Systems discharge within 10 seconds and provide an extinguishing concentration. The room integrity provided hazard should keep the extinguishing concentration indoors for 10 minutes.
Usage Areas of SAFE227 Fire Extinguishing Systems
Below, some of the most frequent usage ares are listed:
-
Data Centers,
-
IT and Server Rooms,
-
UPS Rooms,
-
Electrical Cabinet Rooms,

What Equipment Do SAFE227 Fire Suppression Systems Consist of?
HFC227ea fire extinguishing agent is used in fire extinguishing systems. Fire extinguishing systems consist of system cylinders, system valves, valve accessories (manual, electric and pneumatic actuators), fire extinguishing agent, discharge pipes with fittings, discharge nozzles and hydraulic calculation software. In order to start the fire extinguishing system automatically with a fire scenario, installations contain conventional fire detection systems with cross zone detection scenario.
What Does System Approval Refer to?
System approval commits that the fire extinguishing system extinguishes fire if it is installed within the stated design criteria and limitations of the manufacturer.
Requirements for system approval:
● Testing and certification of a third party test institution for all the components included in the system according to related manufacturing standards individually.
● Instruction manuel of the approved system where design standards, system limitations, equipment list and Equipment combinationsof the system are defined.
● System approval certificate, prepared after extinguishing tests by the third party test institution according to the instruction manuel

Design Criterias About SAFE227 Fire Extinguishing Systems
SAFE227 systems are defined as Clean Agent in ISO 14520-5 / EN 15004-2 design standards. The statement “Clean Agent” means, under defined design parameters, the fire extinguishing agent provided to the protected hazard is not harmful on human health and living creatures. The design concentrations to extinguish fire, defined in ISO 14520-5 / EN 15004-2 and two levels of concentrations defined as NOAEL and LOAEL are indicated on the below table.
7,90%

NOAEL – Highest design concentration used, of the extinguishing agent in which no harm detected on human health and living creatures.
LOAEL – Lowest design concentration used, of the extinguishing agent in which negative conditions observed on human and living creatures’ health.
About HFC227ea Fire Extinguishing Agent
With the prohibition of the use of Halon Gas in Fire Extinguishing Systems in the Montreal Protocol, which entered into force on 01.01.2008, HFC227ea fire extinguishing agent has become the most suitable and reliable extinguishing agent for system manufacturers.
The molecular formula of SAFE227 fire extinguishing agent is CF3CHFCF3, chemical name is 1,1,1,2,3,3,3 - Heptafluoropropane and ASHRAE designation is HFC227ea. This fire extinguishing agent is used in countless applications in more than 70 countries and chemically extinguishes the fire with its rapid cooling effect.
HFC227ea extinguishing agent is UL and FM approved (regardless of system and equipment approval).
Distinguishing marks of HFC227ea fire extinguishing agent from Halon and other HFC extinguishing agents are:
● Ozon depletion potential (ODP) is zero.
● Global warming potential (GWP) is very low, almost neglectable.
● Atmospheric lifetime is 34,2 years.
