In industrial and commercial environments, electrical equipment is often installed and operated inside electrical cabinets. However, these enclosures are frequently exposed to complex environmental conditions such as low temperatures, high humidity, and even frequent temperature fluctuations. These factors not only affect the normal operation of the equipment but can also lead to condensation, causing short circuits, corrosion, and even safety incidents.
To ensure a stable internal working environment for the cabinet and prevent hazards caused by moisture or low temperatures, it is particularly important to install a suitable heater. But with so many types of heaters available on the market, how do you choose the one that best suits your application needs?
Before selecting a heater, it’s essential to assess the environment where the electrical cabinet is located:
Ambient Temperature: Is the cabinet in a consistently cold environment? What is the lowest temperature?
Humidity Level: Is there a risk of condensation? Is the air humidity high?
Equipment Operating Temperature Range: What are the operational temperature requirements for the electrical components inside the cabinet (e.g., PLCs, inverters, etc.)?
The answers to these questions will directly influence the selection of the heater type and power configuration.
Currently, the most common types of electrical cabinet heaters include:
Principle: Heat is generated by current passing through a resistive wire.
Features: Simple structure, low cost, high reliability, but relatively high energy consumption and no precise temperature control.
Recommended Use: Suitable for general industrial applications where temperature control accuracy is not critical.
Principle: Utilizes Positive Temperature Coefficient (PTC) materials that automatically reduce power once a set temperature is reached.
Features: High safety, energy-efficient, no need for additional thermostats.
Recommended Use: Ideal for precision control systems requiring accurate temperature regulation and energy savings.
Features: Equipped with a thermostat or hygrostat that automatically turns the heater on/off based on preset values.
Advantages: Prevents overheating, saves energy, maintains a stable internal cabinet environment.
Recommended Use: Suitable for high-end equipment or data centers sensitive to temperature fluctuations.
Principle: Directly heats object surfaces through infrared radiation.
Features: Rapid heating, high efficiency, but requires careful placement to avoid localized overheating.
Recommended Use: Applications with space constraints or those requiring quick heating.
Protection Rating: Select products with an IP rating of at least IP54 to prevent dust and moisture ingress.
Installation Location: It is recommended to install the heater at the bottom or side of the enclosure for better air circulation. Avoid placing it near cables or electronic components to prevent local overheating.
With the development of industrial automation, more and more heaters now integrate smart features, such as:
Temperature and Humidity Controllers: Enable automatic on/off cycles, improving energy efficiency and extending heater life.
Explosion-Proof Design: Suitable for flammable or explosive environments, enhancing safety.
Remote Monitoring Interface: Supports connection with PLCs or IoT platforms for remote management and maintenance.
