Panel AC vs Cooling Fans: Which Is Better for Control Panels?
In industrial environments, control panels, PLC cabinets, and VFD drives are the brain of your operations. Many factories still rely on simple cooling fans, but here is the truth:Your exhaust fan might be silently damaging your electronics every single day.
Cooling fans pull dust, moisture, and hot ambient air directly into sensitive circuits. Adhunik Powertech’s Panel Air Conditioners offer a smarter, safer, closed-loop solution.
What Happens When You Use Only Cooling Fans?
Exhaust fans don’t cool your panel—they only circulate external contaminants inside it.
Dust & Carbon Buildup
Industrial dust settles on PCBs and contactors, causing insulation failure and arcing.
Moisture Ingress
Humidity enters the panel, leading to corrosion, rust, and leakage currents.
Hot Air Intake
In summer, fans push 45°C+ ambient air into your panel, increasing internal heat.
Frequent Failures
Overheating shortens the life of PLCs, drives, relays, and power supplies.
Higher Maintenance
Spend more on manual cleaning, component replacement, and unplanned shutdowns.
Industrial Panel AC: The Correct Cooling Choice for Control Panels
A Panel AC is specifically designed for electrical cabinets. It doesn’t pull outside air inside; instead, it creates a closed-loop system that keeps electronics safe from factory pollutants.
Sealed Cooling System
No dust, moisture, or oil fumes enter your panel. It creates a closed-loop environment that isolates sensitive electronics from the harsh factory floor.
Consistent Temp Control
Maintains ideal internal temperatures even during peak Delhi NCR summers. Precise thermal management prevents VFD and PLC tripping.
Longer Equipment Life
Reduces thermal stress on capacitors and transistors. Stable cooling can extend the functional life of your automation by up to 300%.
Industrial Efficiency
Modern panel ACs are engineered for 24/7 heavy-duty environments, consuming optimized power while maximizing equipment uptime.

Frequently Asked Questions
Is Panel AC better than an exhaust fan for control panels?
Yes. Adhunik Powertech Panel AC provides sealed cooling and prevents dust, moisture, and heat damage, unlike exhaust fans which pull in contaminants.
What size Panel AC do I need?
Size depends on panel dimensions, heat load of internal components (VFDs, PLCs), and ambient temperature. We recommend a professional heat load calculation.
Can Panel AC work in dusty environments?
Absolutely.Adhunik Powertech Panel AC is built for harsh industrial environments where open fans cause dust and heat damage, ensuring safe and reliable cooling for control panels.
Is it suitable for PLC and VFD panels?
Yes, automation panels require stable temperatures (usually below 35°C). Powertech Heavy duty Panel AC is the gold standard for protecting these investments.
