How Does Electrical Enclosure Air Conditioners Work?

An electrical enclosure air conditioner provides a closed-loop cooling system.

Implying, it completely isolates the internal components of the electrical enclosure from the external environment.

Therefore, your electronic components will not be affected by surrounding elements in the environment, such as dirt, water vapour, etc.

Basically, the electrical enclosure air conditioner will “suck” heated air around the enclosure.

The air around the components become hot as a result of heat dissipated by the electronic components.

It results in high heat load that can eventually damage components.

After “sucking” the hot air, the enclosure air conditioner directs in into an evaporator coil.

The evaporator coil cools the hot air and recirculates it within the electrical enclosure.

This air will then cool the hot electrical components in the enclosure, maintaining their temperature to a suitable level.

Remember, this cycle will continue automatically until you stop it.

In case of any fault, the electrical enclosure alarm will automatically turn on.

Can You Use Air Conditioner in NEMA 4 Enclosures?


An air conditioner will maintain suitable conditions of the enclosure without compromising the NEMA 4 specifications.

Electrical enclosure air conditioner offers a closed-loop cooling system, which is suitable for both indoor and outdoor applications.

NEMA Enclosure

NEMA 4 Enclosure

Enclosure air conditioners maintain a cool and clean environment within the enclosure.

This is because no unwanted particles or heat will enter the enclosure.

Furthermore, for highly contaminated areas, or when the ambient temperature is extreme, you can opt for a water-cooled air conditioner.

Still depending on the enclosure NEMA standards, the electrical enclosure manufacturing company will customize cooling systems to your unique specifications.

What is Closed-Loop Cooling System in Enclosures?

The closed-loop cooling system is the process of maintaining an optimal operating temperature within an enclosure, while completely isolating the external and internal environments of the electrical enclosure.

Implying, electrical enclosure cooling systems, should maintain the temperature of the enclosure, within a suitable range.

At the same time, it should prevent ambient air from entering the enclosure.

As you can see from the figure below, the working principle is straight forward:

Methods of cooling electrical enclosure

  • Step 1: Cooling system sucks hot air electrical components produce within the electrical enclosure
  • Step 2: Air conditioner dehumidifies and cools the air in a single process
  • Step 3: It forces cooled air back into the enclosure

From the figure above, you can see no air leaves the enclosure, unlike the electrical enclosure natural convection cooling and enclosure forced convection cooling.

The main benefits of an electrical enclosure closed-loop cooling system include:

  • Suitable for specific NEMA enclosures
  • Although the initial installation cost is high, they are cost-effective in the long run
  • Suitable for enclosures in hostile environments such as extreme external temperature, acid rain, splashing water, etc.
  • Saves energy
  • Eliminates the possibility of hot spots in the electrical enclosure
  • Suitable for both indoor and outdoor applications

For Optimal Cooling, Should You Install Electrical Enclosure Air Conditioner or Fans?

Whether to choose electrical enclosure fan or air conditioner will depend on the prevailing environmental conditions.

Moreover, the cooling requirements also play a significant role.

The guiding principle should be achieving optimal heating, which is cost-effective at all times.

Electrical enclosure fan and ac

Electrical enclosure fan and A/C

For optimal cooling, you should focus on the following:

· NEMA Rating

NEMA rating will help determine the type of cooling system you should use.

For example, a closed-loop enclosure air conditioner is suitable for NEMA 4x enclosures.

Such enclosures require a cooling system that completely isolates them from the external environment (ambient air).

On the other hand, for NEMA 1 enclosure, an enclosure fan will provide a cost-effective cooling process.

· Enclosure Cooling Mechanism

When it comes to closed-loop cooling requirements, you need an electrical enclosure air conditioner.

However, for forced air cooling, a fan will be a perfect choice.

· Internal Heat Load

In most cases, if the internal heat load is high, go for an enclosure air conditioner.

Otherwise, you can use an electrical enclosure fan.

· Installation Environment

Some environments such as oven, sea or chemical production areas may require complete isolation of electrical enclosure interior.

In such situations, the best option is an electrical enclosure air conditioner.

However, for indoor or where you need NEMA type 1 enclosure, an electrical enclosure fan will work.

To optimize the electrical enclosure thermal management process, discuss your requirements with the electrical cabinet manufacturer.

How Much Power Does Panel Air Conditioner Use?

The amount of power a panel air conditioner consumes depends on many factors, such as:

Therefore, you need an electrical enclosure air conditioner because:

i. They are easy to program; hence, you can control or monitor their performance remotely. Alternatively, you can integrate it with the existing SCADA or DCS systems.

With this, you can monitor and maintain the temperature within the electrical enclosure.

ii. It offers closed-loop cooling systems; thus, dirt particles, corrosive agents, humidity, etc. will not enter the enclosure. Basically, it “isolates” external environment from inside the electrical enclosure.

iii. With the condensate evaporator, you don’t need extra external tubing or drainage systems. It offers better service in remote and hostile environmental conditions.

What is Thermal Management in Electrical Enclosures?

Electrical enclosure thermal management is the process of maintaining a suitable working temperature within the enclosure.

It involves monitoring and controlling the temperature dissipated by electrical components in the electrical enclosure.

To adopt a good electrical enclosure thermal management procedure, you need to:

i. Choose suitable electrical enclosure cooling mechanisms such as air conditioner, forced convection fans, ventilation systems, heat exchangers, etc.

ii. Understand operating temperature of every component in an electrical enclosure

iii. Know all environmental conditions and parameters within an area where you intend to install the electrical enclosure

iv. Know electrical enclosure material and dimensions

v. Calculate the total power loss

What Does BTU Mean?

BTU refers to British Thermal Unit.

The amount of heat you will need to raise the temperature of 1 pound of water to one degree Fahrenheit is equivalent to 1 BTU.

What Does BTU Mean in Enclosure Air Conditioning?

BTU is basically a measure of energy; therefore, you can use it to measure the capacity of the enclosure air conditioner.

Implying, BTU is the amount of heat air conditioner can remove in an electrical enclosure per hour.

For instance, when you want to determine how many BTUs you will need for an electrical enclosure, you have to:

  • Determine the size of the electrical enclosure
  • Know the electrical components in the enclosure
  • Where you will install the electrical enclosure

Depending on these specifications, you can choose an enclosure air conditioner with a low BTU rating (small) or high BTU rating (large).

Therefore, an increase in BTU rating will mean the size, cost, and weight of enclosure air conditioner will also increase.

Can NEMA 3r Enclosures Use Air Conditioners?

Are Electronic Enclosures with Cooling Fans More Effective than A/C System?

The level of efficiency will depend on the situation at hand.

For instance, for NEMA 4x enclosures, an air conditioner will be more efficient.

On the other hand, for NEMA 1 enclosures, installing a fan cooling system will be more efficient.

Therefore, both enclosure fans and enclosure air conditioners are efficient cooling mechanisms.

You only have to evaluate the enclosure thermal management requirements and choose a suitable cooling system.

What is a Sealed Enclosure Cooling System?

Sealed enclosure cooling system is cost-effective and requires small space in an enclosure thermal management system.

It is perfect for situations where the temperature within the enclosure is higher than the temperature outside the enclosure.

Therefore, sealed cooling systems is an example of the above ambient enclosure thermal management system.

Although sealed cooling systems can work in both indoor and outdoor electrical enclosures, their capacity is normally limited.

Furthermore, with sealed enclosure cooling systems, the internal section of the enclosure is completely isolated from the surrounding environment.

A practical example of a sealed enclosure cooling system is a closed-loop air conditioner.
