Electrical enclosure overheating can lead to costly downtime and equipment failures. In hazardous environments, ATEX-certified Cabinet Coolers provide a safe and compliant cooling solution. When conventional cooling methods cannot be used due to safety concerns, ATEX-certified Cabinet Coolers from EXAIR provide a reliable and compliant solution.
Heat Build-Up and Explosion Risks in Industrial Environments
Electrical components continuously generate heat during operation.
In production facilities with high ambient temperatures, such as automotive plants, manufacturing facilities and operations located in hot climates, heat can quickly build up inside electrical enclosures.
When high temperatures combine with flammable gases, vapors or combustible dust, additional safety requirements come into play. Fans and air conditioners that rely on electrically driven components can become potential ignition sources and are therefore often unsuitable for use in ATEX-classified areas.
Why Conventional Cooling Solutions Fall Short in Hazardous Areas
Traditional cooling systems typically depend on electric motors, compressors or moving mechanical components. In hazardous locations such as ATEX Zone 2 and ATEX Zone 22, these devices can be problematic or prohibited.
At the same time, manufacturers face increasing demands for operational safety, regulatory compliance and maximum equipment availability.
ATEX-certified Cabinet Coolers provide a technically safe alternative. Powered by ordinary compressed air, they operate without electrical components or moving parts inside the enclosure. This significantly reduces the risk of ignition sources while maintaining reliable heat removal from sensitive electrical equipment.
Understanding ATEX Zones, Standards and Certification
- ATEX regulations govern the use of equipment in potentially explosive atmospheres. Zone 2 refers to areas where explosive gas atmospheres are unlikely to occur during normal operation and, if they do occur, are present only for a short period. Zone 22 applies to similar conditions involving combustible dust.
- Cabinet Coolers designed for these environments must comply with strict standards such as EN IEC 60079-2, which covers purged and pressurized enclosures.
- ATEX-certified cooling systems remove potentially hazardous substances from the enclosure before start-up and then maintain a slight positive pressure. This prevents explosive gases, vapors or dust from entering the enclosure from the surrounding environment.
Reliable Cooling Through Purge and Pressurization Technology
Compressed air operated Cabinet Coolers use vortex tube technology to generate a continuous stream of cold air. They require neither refrigerants nor electrical power.
The result is a rugged, low-maintenance cooling solution that operates reliably even in high-temperature environments. Installation is typically completed using standard enclosure openings, without compromising the enclosure’s protection rating (e.g. IP66 or NEMA 4X).
In addition to regulatory compliance, users benefit from reduced maintenance requirements, uniform temperature distribution and optional thermostat control for more efficient compressed air usage. In continuously operating facilities, ATEX-certified Cabinet Coolers help improve both system reliability and equipment uptime.
