5 Climate Precautions to Take with an Industrial Control Panel Enclosure

Regional climates play a critical role when planning control panel installations. Carefully analyzing climate conditions at the control panel enclosure site prior to installation helps identify the extent to which the electrical components will be exposed. Harsh indoor and outdoor climates can create multiple sources of risk for potential electrical equipment failure.

How to Regulate Temperature for Outside Plant Enclosures


Although the GR-3108-CORE specification for outside plant cabinets allows a relatively wide range of cabinet operating temperatures, there are many instances when it is better to regulate the temperature to within a relatively small temperature range. This is because some equipment needs to be kept reasonably cool in order to function optimally, and, also, equipment life is extended at lower temperatures.

In order to control the temperature inside the enclosure, it is generally necessary to implement some form of enclosure cooling and, in some instances, to also use cabinet heating. Here's how you can economically regulate the temperature of your outside plant cabinets.

What Are the Benefits of Heat Pipe Technology for Enclosure Cooling?

Heat pipe technology is an efficient yet effective approach to enclosure cooling that contains no moving parts except for air circulation fans. This characteristic makes it highly suitable for applications that require a sealed enclosure but have limited power supplies. Noise levels are negligible, so these units can be used in areas where noise would be a problem.

8 Thermal Management Tips for Outside Plant Applications

The increased power density of telecom equipment along with the vulnerability of some components to excessive temperature variation means the thermal management of outside plant equipment has become crucial. Outside plant cabinets are exposed to widely fluctuating ambient temperatures, yet their internal temperatures must be maintained within the limits specified by GR-3108-CORE. Here are eight tips that will help optimize the thermal management of outside plant cabinets.

5 Key Steps in Enclosure Cooling Design

Electrical enclosures protect equipment from mechanical and environmental damage. However, by confining equipment inside an enclosure, the waste heat generated by each component builds up, raising the enclosure temperature above manufacturer recommendations for the components.

To maintain proper equipment performance levels, an enclosure cooling system is typically required. When designing a cooling system for an electrical enclosure, it’s important to follow these five key steps:

How Temperature Control Affects Control Panel Design

Control panel designers face an ongoing conflict between meeting the technical requirements for electrical control panels and budget allocations. On the one hand, there's the desire to choose generously sized control panels that optimize the layout of electrical equipment and, on the other, the need to exercise tight cost restraints that inevitably mean compromises are made. There's also the need to consider the space that's available in the plant as well as the environmental conditions that are present.

One of the biggest challenges is to manage the enclosure temperature and ensure the heat distribution inside the control panel is such that equipment temperatures are kept within specification.

Why Temperature Is Critical to an Industrial Control Panel Enclosure

Components in an industrial control panel enclosure are subjected to heat generated by equipment inefficiencies as well as heat transferred from outside sources, high ambient temperatures, and nearby industrial machines. The components may also experience low temperatures due to cold weather.

As long as they are maintained within the manufacturers’ specified temperature range, the reliability, performance, efficiency, and physical integrity of the components will be protected. However, once the temperature inside the enclosure exceeds that range—even for short periods of time—risk of early failure, leading to unexpected costs and downtime, increases.

The Ambient Environment & Industrial Control Panel Reliability


The environment of an industrial control panel has a significant effect on system reliability and should be carefully evaluated during the control panel design stage. Environmental aspects that affect industrial control panels include ambient temperature, contamination, corrosion and vibration, and different strategies are required to ameliorate their effects. These include the installation of effective cooling systems, methods to prevent equipment contamination, corrosion protection and steps to reduce the effects of equipment vibration.
