FK-5-1-12 (Novec 5112) and HFC227-EA (Heptafluoropropane) are both clean agent fire suppression agents with distinct characteristics. Here's a comparison between the two:
1. Environmental Impact:
- FK-5-1-12: It has a low global warming potential, zero ozone depletion potential, and a short atmospheric lifetime. It is considered environmentally friendly.
- HFC227-EA: It has a low global warming potential and zero ozone depletion potential. It is also considered environmentally friendly.
2. Chemical Composition:
- FK-5-1-12: It belongs to the family of fluorinated ketones and is composed of carbon, fluorine, and oxygen.
- HFC227-EA: It belongs to the class of halocarbon compounds and is composed of carbon, fluorine, and hydrogen.
3. Fire Suppression Mechanism:
- FK-5-1-12: It removes heat from the fire and interrupts the combustion process by absorbing energy and reducing the flame temperature.
- HFC227-EA: It operates by absorbing heat and interfering with the chemical chain reactions involved in the combustion process.
4. Application:
- FK-5-1-12: It is suitable for a range of applications, including data centers, control rooms, museums, and telecommunications facilities.
- HFC227-EA: It is commonly used in data centers, telecommunications facilities, server rooms, and other critical environments.
5. Residue and Cleanup:
- FK-5-1-12: It does not leave any residue after discharge, minimizing post-fire cleanup and potential damage to sensitive equipment.
- HFC227-EA: It does not leave any residue after discharge, allowing for easy cleanup and minimal damage to protected assets.
6. Storage and Handling:
- FK-5-1-12: It is typically stored as a liquid under high pressure and requires specific handling procedures.
- HFC227-EA: It is stored as a liquid under high pressure and also requires proper handling and storage practices.
Ultimately, the choice between FK-5-1-12 and HFC227-EA depends on specific requirements, regulations, and the preferences of the application. Consulting with fire protection experts and considering local regulations can help determine the most suitable agent for a particular scenario.
