When we think of an industrial freezer maintained at sub-zero temperatures we don’t think of it as a fire hazard. But the cooling agents used by the HVAC systems, combined with the extremely dry air in cold storage warehouses, results in a high fire load. We also cannot rely on traditional smoke detectors that are only reliable down to -20°C, while freezers are typically maintained at -26°C. And of course, triggering water sprinklers inside a frozen environment cannot but cause extensive damage to the stored goods, and the facility itself, while the cost of defrosting and replacing inventory becomes prohibitive, putting your entire business at risk. Alternative gas suppression systems will contaminate the goods in food storage warehouses. But we offer a solution.

  • Extremely dry air due to condensing air humidity and sub-zero conditions puts the facility at risk of fire.

  • High energy density due to the concentration of electrical equipment of various types and ratings; defrosters, compressors, retrieval vehicles,  etc..

  • Electrical and cooling equipment is prone to technical faults and are the main cause of fires.

  • Coolant leaks within the HVAC systems can also be the cause of fires.

  • Presence of packaging material made of cardboard, and frozen food containing fats will contribute to a higher fire load.

  • Narrow storage aisles with high racks create ideal conditions for rising combustion gases to ignite and spread the fire.

  • Smoke and soot will contaminate any goods within vicinity.

  • Disruption of operations is the least of your concerns if you also have to deal with any environmental damage, and total write-offs of your inventory.


  • Gas-tight envelope in your freezers gives you the ability to control the atmospheric composition throughout the facility, and prevents any toxic smoke or combustion gases from accumulating to dangerous levels.

  • Low oxygen atmosphere where coolant leaks or electrical faults will not lead to combustion of flammable materials.

  • No risk of water being deployed inside a sub-zero environment, or fire suppression gases contaminating your goods.

  • Fire Protection conditions are always on, 24/7/365. Do not wait until a fire starts!


We are ready to lead you into the future of life and safety systems. Replace conventional passive fire suppression, with active always-on fire prevention.
