Condensed aerosol systems suppress fire using an extremely fine aerosol of microscopic particles rather than a gas or liquid. The aerosol is created by a compact generator and does not need cylinders, pipework or a pressurised store, which makes these systems small, self-contained and well suited to protecting enclosed risks such as electrical cabinets and machinery. MEP designs, supplies and installs condensed aerosol systems across the UK for applications where space is tight and a simple, effective solution is needed.
Inside each generator is a solid compound that, when activated, converts into a dense aerosol of tiny potassium-based particles suspended in gas. These particles interrupt the chemical chain reaction of the fire at a molecular level, putting it out quickly without significantly reducing oxygen. Because the aerosol behaves almost like a gas, it fills the enclosure and reaches around obstructions. Generators can be triggered automatically by detection or thermally, and no pipework or distribution network is required.
Condensed aerosol is ideal for small, enclosed spaces: electrical and control cabinets, switch rooms, engine compartments, wind turbine nacelles and similar equipment risks where a compact, low-maintenance system is an advantage. The generators have a long service life and take up very little room. It is best suited to protecting equipment in normally unoccupied enclosures. We assess the risk, select and position the generators to suit the volume, and integrate them with detection so the system responds automatically.

A compact system that extinguishes fire by releasing a fine aerosol of microscopic particles from a solid generator, without cylinders or pipework.
The aerosol particles interrupt the chemical chain reaction of combustion at a molecular level, extinguishing the fire quickly without significantly reducing oxygen.
Small enclosed risks such as electrical and control cabinets, switch rooms, engine compartments and machinery, where a compact, self-contained system is ideal.
No. The agent is stored as a solid inside the generator and converts to aerosol on activation, so no pressurised cylinders or distribution pipework are needed.
It is best suited to normally unoccupied enclosures. Where a space may be occupied, we assess suitability carefully as part of the design.
