ATEX Vortex AC – Certified Enclosure Coolers for Hazardous Environments

ATEX Vortex AC coolers are compressed-air-powered enclosure cooling systems designed for hazardous and classified environments. Built by Vortec, these units deliver a reliable, low-maintenance alternative to traditional industrial air conditioners.

Using a vortex tube to separate compressed air into hot and cold streams, the ATEX Vortex AC channels clean, cold air into enclosures while maintaining positive pressure that prevents dust, dirt, and moisture from entering.

With ATEX and IECEx certifications, these systems are trusted in Zone 2 and Zone 22 applications, providing safe cooling where explosive atmospheres may occur.

FAQs – ATEX Vortex AC

Standard cooling systems are not designed to operate safely in classified zones where flammable gases, vapours, or dust may be present. ATEX Vortex AC units are certified specifically for these environments, preventing ignition risks while providing reliable enclosure cooling.

Most ATEX Vortex AC models are designed for quick installation and require only a compressed air connection. No wiring or external power is needed, which simplifies setup and reduces installation time compared to traditional cooling systems.

Because they have no moving parts and use no refrigerants, these units require minimal servicing. This reduces replacement part costs and downtime, especially compared to compressor-based air conditioners that rely on regular servicing.

Yes, many models are suitable for outdoor use when installed on properly sealed enclosures. Their positive-pressure design prevents contaminants and moisture from entering, even in demanding outdoor or washdown conditions.

ATEX Vortex AC models come in capacities ranging from 900 to 5,000 BTU/hr, covering small, medium, and large enclosures. Pelmar Engineering can assist with calculating the BTU/hr required to match specific heat loads and ambient conditions.

By maintaining stable internal temperatures and preventing dust and moisture ingress, ATEX Vortex AC units help extend the lifespan of electronic components. This reduces failures such as tripped breakers, drift in controls, and malfunctions of digital displays.
