How an Efficient Cabinet Cooling System Can Reduce Unwanted Electrical Equipment Maintenance Costs


When you purchase an electrical enclosure to house your equipment and keep it safe, you’re investing in the longevity of all of the electrical components. Electrical equipment can produce substantial heat, so also adding a cabinet cooling system to the purchase can keep your unplanned maintenance needs to a bare minimum. Having the proper operating temperature reduces overall system fatigue and keeps your equipment at peak condition.

Regardless of whether you choose an air conditioner, air to air heat exchanger, or filtered fan, the piece of mind that comes with keeping your electrical equipment at an appropriate operating temperature is priceless. Each different type of cabinet cooling system has it’s specific advantages, so knowing which one will work for your application is important. An air conditioner can cool the interior temperature to below the ambient air temperature, and provide closed loop cooling. An air to air heat exchanger provides closed loop cooling, but is limited by the ambient air for the minimum internal temperature. A filtered fan does not provide closed loop cooling, and is similarly limited by the ambient air temperature for how well it can cool the enclosure.

Closed Loop Cooling

With both the air conditioner and heat exchanger, you can achieve closed loop cooling for your electrical enclosure. This allows your equipment to function without the potential of getting contaminated by dust and dirt, or any other airborne particulate matter. During normal, closed-door operation, the interior of the enclosure is completely inaccessible from the exterior. Of course, during maintenance and other issues that require the door to be open, the enclosure is susceptible to contamination.

This allows you to reduce the amount of time cleaning dust and dirt out of your electrical equipment during regular maintenance intervals. The reduced labor time will be reflected in cost savings, all due to installing a closed loop cabinet cooling system.

Corrosion Control

With the active humidity control in the air conditioner, the equipment is exposed to much lower moisture levels. Moisture can lead to corrosion on electronics if left unchecked, so by controlling humidity you will reduce the possibility of your equipment corroding. This in turn can help lengthen the lifespan of each component, as well as reduce unplanned downtime due to corrosion. Replacement and repair costs are drastically reduced as well.

Temperature Control

All three cabinet cooling system options provide excellent temperature control. Keeping temperature within the manufacturer’s specified operating range is key for equipment longevity. Elevated temperatures can lead to premature failure, warping or breaking of sensitive components, and increased downtime. By moderating temperature inside your electrical enclosure, you can be sure that your equipment will function as intended between planned maintenance tasks.
