What You Need to Know Before Investing in Enclosure Cooling

Stay Informed

Without proper cooling components, electrical equipment is exposed to fluctuating temperature conditions that can drastically affect performance and lifespan. The inside of an equipment cabinet can generate and trap as much heat as a home furnace – just imagine the damage those temperatures can cause your equipment.

Investing in enclosure cooling solutions allows you to maximize uptime and minimize downtime by keeping equipment at an optimal temperature and addressing concerns such as condensation and heat damage.  

The Effects of Temperature Variations

As the push to go digital continues, processing power increases and equipment has to work even harder to produce results – meaning more heat and energy being output into the enclosure space. Even though the equipment itself is what is creating a vast majority of the temperature variations, electrical equipment is sensitive to temperature changes. Meaning even the smallest fluctuation in temperature can produce condensation or overheat the equipment – two major concerns in electrical equipment storage areas.

Condensation Concerns in Enclosures

Condensation is a major concern when it comes to electrical equipment enclosures. Condensation is referring to the moisture that builds up when a cold surface meets humid air. A few common ways that moisture can work its way into an enclosure include a door left open for maintenance, building temperature variations between the inside and outside of the enclosure, and changes in outside temperatures due to weather conditions.

Moisture can cause a number of problems for equipment, such as:

  • Corrosion and short circuiting
  • Rusting of critical components
  • Potential equipment failures
  • Premature system performance loss

Heat Damage Concerns in Enclosures

Without a proper cooling method, overheating is a real concern for storage rooms. To maximize the lifespan of electronic devices, you’ll want to make sure to keep electronics cool and running smoothly. If heat damage occurs, it can affect your capital expenses and daily business operations. A few common sources of damaging heat include controllers, drives, transformers, high ambient temperatures, welding processes, and much more.


Consequences of heat damage in your storage facility can include:

  • Component failure
  • Service outages
  • Reduced system lifespan
  • Lost revenue

A Minimal Investment for Maximum Cooling

It’s not often that investing in new equipment is seen as a minor venture. But when it comes to cooling your electrical equipment space – it’s just that, a minor upfront investment that presents major benefits.

An integrated cooling solution will help the components within the enclosure last longer by providing an optimal temperature set point. Managing temperatures and reducing the presence of condensation or heat damage will extend product lifespan and save you time and money in costly repairs. The cost of replacing and repairing equipment can quickly begin to add up – eventually costing more than the investment into a cooling solution.

Cooling solutions not only mitigate condensation and excessive heat problems, but will also produce a more efficient system that lowers operating costs. All of these factors add up to additional financial benefits you’ll gain, by making a minimal initial investment.

Improve Equipment Performance and Reduce Replacement Costs With Enclosure Cooling

With the amount of data processed every day, the investment in electrical equipment cooling has never been more important. Ensuring optimal temperate will reduce replacement costs and extend the lifespan of your equipment – with minimal upfront investments.
