Aerosol Fire Suppression System
Condensed aerosol fire suppression is the newest and cleanest generation of automatic fire extinguishing technology. Supremex Equipments distributes HAFEX® aerosol fire suppression systems, manufactured by YG Fire Security (Turkey) — a manufacturer producing the largest aerosol fire extinguishing generators in the world in both K and S types, holding 28 trademark patents and operating in 18 countries.
A condensed aerosol generator contains a solid, potassium or strontium nitrate–based compound. On activation, this compound undergoes a rapid exothermic reaction and releases a dense cloud of micron-sized aerosol particles into the protected space. These particles interrupt the fire's chemical chain reaction at a molecular level and absorb heat, extinguishing the fire quickly — with no piping, no nozzles, no pressure vessel and no cylinder recharge required.

Frequently Asked Questions
What is an aerosol fire suppression system and how does it work?
A condensed aerosol generator contains a solid potassium or strontium nitrate compound. When triggered by heat or an electrical signal, the compound undergoes an exothermic reaction and releases billions of fine aerosol particles that interrupt the fire's chemical chain reaction and absorb heat — extinguishing the fire without water, gas cylinders or piping.
Is HAFEX aerosol safe for electronic equipment?
HAFEX's S-Type aerosol is specifically used in the HFX-200R/400R rack cabinet fire extinguishing system, which is designed so the extinguishing process does not damage the electronic equipment within the cabinet. This makes S-Type suitable for server racks and IT/data equipment protection. As with any fire suppression discharge, occupied spaces should be evacuated during activation as standard safety practice.
What fires and applications is HAFEX suitable for?
HAFEX aerosol suppresses Class A, B and C fires and fires in electrically energized equipment, per NFPA 10 and EN 2 standards. Typical applications include electrical panels, control rooms, base stations, engine compartments, generator rooms, substations, warehouses, wind turbines and CNC/production machinery.
What installations require an aerosol fire suppression system?
HAFEX aerosol units suit compact, sealed or semi-sealed enclosures — electrical cabinets, engine bays, rack cabinets, telecom shelters, and small to mid-sized rooms across the usage areas listed above.
How is a HAFEX aerosol system activated?
HAFEX units can be activated electrically (via a fire control panel such as the 200A+, HFX-48GSM or 200L), thermally (via the HFX-TBA thermobulb at 68°C, 79°C, 93°C or 141°C), or by battery-powered activator (BPA) connected to a linear heat detection cable — with no external power required for the BPA option. Manual release is also available from the control panel.
What is the difference between K-Type and S-Type HAFEX aerosol?
K-Type (potassium nitrate based) discharges faster and suits most general electrical panel and engine compartment applications. S-Type (strontium nitrate based) discharges more slowly for extended dwell-time, making it well suited to larger enclosed volumes such as rack cabinets and bigger electrical rooms where sustained suppression coverage matters more than speed.
