Novec 1230 Gas Fire Suppression

Concept Fire Suppression Ltd’s Novec 1230 Clean Chemical Fire Suppression Agent is becoming more and more widely used as an alternative to FM200 and FE227 due to it’s better environmental credentials than other clean chemical agents.

Manufactured by 3M, Novec 1230 fluid is a recent addition to the industries product range and is specified by many end users, consultants and insurers as the clean chemical agent of choice.

The Agent

Stored as a liquid like FM200 and FE227, Novec 1230 fire protection fluid is discharged as a gas but as its boiling point is 40 deg C the nozzle is designed to help it vaporise. It leaves no residue and is nonconductive. It can be used in class A fires, electrical, wood, paper and fabric and class B flammable liquids. Novec 1230 is usually stored in similar cylinders to FM200 and FE227 and super pressurised to 25 or 42 bar although 25 bar is more usual using Nitrogen.

Novec 1230 has an Ozone Depletion Potential of 0 and a Global Warming Potential of 1 equal to that of CO2 and has an Atmospheric Lifespan of just 5 days or less. Although not as environmentally friendly as inert gases Novec 1230 is the best of the clean chemical agents so does offer a good alternative where a client’s policy dictates a greener solution.

Novec 1230 Hardware

Novec 1230 Fire Suppression System
Concept Fire Suppression Ltd use Hygood Sapphire hardware and cylinders which are available in several different sizes from as small as 8L through to 180L. Where multiple cylinders are required they can be manifold together or kept separate and distributed throughout the room, this is known as a Distributed Cylinder System. Pipework is standard schedule 40 and usually arranged as a Distributed Cylinder System with a standpipe arrangement. This cuts down on the pipework required in comparison to a manifold system.

Nozzles are available in 1/2″, 3/4″ 1″, 1 1/4″, 1 1/2″ and 2″ and can be 360 or 180 degree. 360 degree nozzles are where discharge of the agent is required in the centre of the area. 180 degree nozzles are located adjacent to the wall.

The master valve is actuated by a 24v dc signal from the detection control panel which in turn actuates through Kunifer pipework to each cylinder in turn to ensure the required amount of gas is discharged into the room.

As Novec 1230 is stored as a liquid it requires less cylinders than inert gas and therefore requires less storage space. On a room volume of 750m3 Novec would require just 4 cylinders where as inert gas would require 17 cylinders.

Room Integrity Testing

To ensure that the Novec 1230 gas is contained in the room for as long as possible (BS EN 15004 stipulates a minimum of 10 minutes) the room needs to be pressure tested. This checks that the room is sufficiently sealed, that it will maintain the concentration levels required to suppress the fire for the minimum time period. This can only be carried out at the end of the installation or project after the room has been completed and all holes and entry points through the walls, floor and ceiling have been sealed using fire proof materials.
