Heat inside electrical enclosures can lead to component failure, downtime, and inconsistent machine performance. In our latest video, we used a thermal camera to show how quickly an EXAIR Cabinet Cooler reduces temperatures inside a control panel.
Thermal imaging makes the results easy to see in real time. Hot spots across the enclosure begin cooling almost immediately once the Cabinet Cooler is activated, helping stabilize temperatures around critical electrical components.
The video highlights:
Rapid panel cooling
Reduction of hot spots
Consistent airflow across components
Cooling without pulling contaminated plant air into the enclosure
Unlike traditional fan cooling, the EXAIR Cabinet Cooler uses compressed air to cool the enclosure while maintaining positive pressure to help keep dust and debris out.
For facilities dealing with overheating VFDs, PLCs, or electrical panels, thermal imaging provides a clear look at how effective enclosure cooling can improve reliability and reduce downtime.

In today’s fast-paced industrial world, maintaining the performance and longevity of electronic equipment is crucial. Overheating electrical enclosures can lead to costly downtime, and premature component failure. Fortunately, EXAIR offers a reliable, efficient, and innovative solution with their Cabinet Cooler Systems. Paired with their intuitive Cabinet Cooler System Calculator, choosing the right cooling solution has never been easier. Let’s dive into what makes EXAIR Cabinet Coolers stand out and how the system calculator simplifies the selection process.

EXAIR Cabinet Coolers are compressed air-powered cooling systems designed to keep electrical enclosures at optimal temperatures, even in the harshest environments. Unlike traditional air conditioners that rely on refrigerants and moving parts, these coolers use vortex tube technology to generate cold air from compressed air. This means no Freon, no maintenance headaches, and no risk of mechanical breakdowns—perfect for industries where reliability is non-negotiable.
Available in a variety of models, EXAIR Cabinet Coolers cater to different needs:
NEMA 12: Ideal for dust-tight, oil-tight indoor environments.
NEMA 4: Built for splash-resistant, indoor/outdoor use.
NEMA 4X: Corrosion-resistant stainless steel for food service or harsh settings.
ATEX: Electrical enclosures located in ATEX Zones 2 and 22, for hazardous gases and dust.
Cooling capacities range from 275 Btu/hr for small panels to 5,600 Btu/hr for larger enclosures, with options for continuous operation or thermostat-controlled systems to save on air usage. Plus, they’re UL-listed, CE-compliant, and easy to install—typically in under an hour through a standard electrical knockout.
Launched as a do-it-yourself solution, the Cabinet Cooler System Calculator is a free, web-based tool available on EXAIR’s website under the Knowledge Base’s Calculator Library. It’s designed to provide instant feedback on the exact model you need, saving time and ensuring accuracy. Here’s how it works:
Input Basic Information: Enter details like:
Enclosure dimensions (height, width, depth).
Current internal and external temperatures.
Maximum external temperature expected.
Desired internal temperature (typically 95°F for most electronics).
NEMA rating required.
Compressed air supply details (pressure and temperature).
Heat Load Calculation: The calculator computes the internal heat load (from electronics inefficiency) and external heat load (from ambient conditions), factoring in variables like solar heat gain if applicable.
Model Recommendation: Within seconds, it spits out the precise Cabinet Cooler model number—complete with cooling capacity in Btu/hr—and a link to learn more or order online.
Before the calculator, you’d fill out a Cabinet Cooler Sizing Guide and wait up to 24 hours for a recommendation. While that process still works (and EXAIR’s team responds promptly), the calculator delivers results in under 5 minutes. It’s perfect for engineers who want quick answers or companies facing urgent overheating issues. Plus, it’s packed with EXAIR’s decades of expertise, ensuring the recommendation compensates for non-optimal conditions like high air temperatures or low pressure.
In keeping with the understanding that we want to take your pain away quickly, not only can you get a recommendation for the right Cabinet Cooler system quickly, but we also keep all of our cataloged models on the shelf, ready for immediate delivery to your facility as quickly as the next day. Our customers have up until 2:00 p.m. Eastern time to get a recommendation and get an order in with us to be delivered the next day if the situation demands it.
EXAIR Cabinet Coolers are a proven, cost-effective way to protect your electrical enclosures from heat-related chaos. Paired with the Cabinet Cooler System Calculator, you’ve got a powerful duo that makes cooling simple, fast, and precise. No more guessing, no more delays—just cold air where and when you need it.
Ready to cool things down? Head to EXAIR.com, plug your specs into the calculator, and see the difference for yourself. Your electronics—and your bottom line—will thank you.
The Intellistat Ion Air Nozzle has been used in clean room applications, most commonly to keep contaminants away from packaging and labeling areas. The Intellistat Ion Air Nozzle has a clean room classification: ISO 14644-1 Class 5, operational. And has recently acquired a new patent.
The +/- 30V offset allows you to achieve a very low residual charge at impressive static decay rates, reducing 1000V down to 100V in just 0.6 seconds. We’ve taken the same engineered nozzle technology used in our line of Super Air Nozzles to ensure the nozzle operates well below the OSHA standards for both noise exposure (29 CFR 1910.95(a)) and dead-end pressure (OSHA 1910.242(b)). The nozzle is also very efficient, minimizing compressed air usage compared to open tubes or pipes commonly used in blowoff applications. At a pressure of 80 PSIG, the Intellistat Ion Air Nozzle consumes just 5.8 SCFM of compressed air.
The nozzle assembly is constructed from durable dissipative polycarbonate to assure its usefulness in applications that require non-conductivity such as circuit boards or electronics manufacturing. It provides ionized airflow useful for removing dust, static, or particulate contaminants in sterile environments such as clean rooms, laboratories, or scientific testing.
In processes that require operators to have both hands free for packaging, testing, or assembly of small parts and products, the Intellistat Ion Air Nozzle is the ideal solution. It includes a 6mm push-in air connection and incorporates red and green LED lights to indicate proper functionality and performance.
EXAIR’s line of Intellistat products is UL listed and CE compliant, following suit with EXAIR’s complete line of Gen4 Static Eliminators.
