The design and installation of an electrical panel require an in-depth understanding of the environmental conditions in which the system will operate. This is essential to choose the most suitable thermal management solutions and minimize the risk of component failures.
Thermal issues are one of the leading causes of electrical panel malfunctions, making effective thermal management a top priority.
Below, we outline the key factors to consider during the design phase to select the most suitable solutions for both indoor and outdoor applications.

Factors to consider for optimal thermal management during design
- Presence of oils or aggressive and corrosive substances: In environments where oils or corrosive substances are present, it is crucial to seal the electrical panel. In these cases, panels and cooling systems with stainless steel or aluminum enclosures are recommended to prevent contamination.
- Dusty or dirty atmosphere: In environments characterized by dust or dirt, the electrical panel must be adequately protected to prevent the ingress of contaminants. Additionally, ventilated systems require highly efficient air filtration.
- Temperature and humidity levels: The ideal internal temperature of an electrical panel is around 35°C. Maintaining a stable temperature and avoiding hot spots helps protect components, reduce the risk of condensation, and lower energy costs.
- Exposure to solar radiation: For outdoor applications, prolonged exposure to sunlight must be considered when selecting materials and conducting thermal calculations.
- Electromagnetic exposure: Evaluating electromagnetic compatibility and potential interference between devices in the environment and within the panel is essential to ensure proper functioning.
- Exposure to rain, snow, and wind: Electrical panels installed in environments subject to such weather conditions require adequate protection to prevent water ingress and the entry of dust and debris. Protection hoods combined with ventilation systems can often be an effective solution.
- Wash-down processes: In the Food & Beverage sector, where frequent washdowns are required to maintain high hygiene standards, panels must be designed to withstand cleaning cycles. Using suitable materials, protection hoods, and seals is therefore essential.
Compliance with industry standards during installation
Industry standards for electrical panels have been developed to enhance safety and encourage efficient design. Once the environmental requirements of the panel have been assessed, it is essential to select components with standardized protection ratings (e.g., IP rating according to EN60529 or NEMA).
By taking these factors into account and selecting the appropriate components, you can optimize system performance, reduce operating costs, and ensure the overall reliability and safety of the electrical panel.
Addressing these challenges with the right solutions is not just a technical matter—it’s an investment to ensure the longevity and efficiency of the entire system.
