What is Enclosure Heater? How Does It Work?
An enclosure heater is a compact heating device designed to protect electrical or electronic components inside cabinets, control panels, or telecom boxes from moisture, condensation, and extreme cold. It ensures that the internal temperature stays within safe operating limits, preventing corrosion, short circuits, and equipment failure.
Enclosure heaters are commonly thermostat-controlled, meaning they automatically turn on or off based on the ambient temperature within the cabinet. When the temperature drops below a preset limit (often around 5–10°C), the thermostat activates the heater. Once the safe temperature is restored, it switches off, making the system energy efficient.
These heaters come in various types—PTC (Positive Temperature Coefficient), convection heaters, fan heaters, and radiant heaters. Most modern versions are self-regulating, safe to touch, and compact enough to be mounted directly inside panels.
The primary function of an enclosure heater is to:
Prevent condensation, which can damage sensitive components.
Protect against freezing, especially in outdoor or uninsulated enclosures.
Extend equipment lifespan by maintaining a stable environment.
They are widely used in telecom cabinets, traffic signal boxes, automation control panels, and outdoor electrical enclosures, especially in cold or humid environments.
In summary, an enclosure heater is a critical solution for maintaining the reliability and longevity of sensitive equipment in challenging environments. It offers low maintenance, energy efficiency, and peace of mind for operators across industries.
What are the Benefits of Enclosure Heater?
Enclosure heaters prevent condensation, protect components from freezing, and extend equipment lifespan. They ensure stable temperatures inside electrical cabinets, reducing failure risks, especially in outdoor or cold environments. Ideal for telecom, automation, and power control systems.
Customer Testimonials
FAQ of Enclosure Heater
Can I use enclosure heaters in wet or washdown environments?
Yes, choose heaters with IP65+ ratings and ensure proper sealing. Our loop heaters with silicone gaskets are ideal for such environments.
Do all enclosures need heaters?
Not necessarily. But if you have temperature swings, condensation, or high humidity, a heater will extend the life of your electrical components significantly.
Are fan heaters better than convective heaters?
Depends on enclosure size. Fan heaters are better for large or unevenly loaded enclosures, while convective units are ideal for compact spaces.
What’s the typical heater wattage for a medium-sized panel?
For an enclosure 800mm x 600mm x 300mm, with outdoor exposure, 120–150W is usually sufficient when controlled by a thermostat.
Can I leave the heater running continuously?
You could—but we recommend thermostat/hygrostat control to save energy and reduce risk of overheating.
Enclosure Heater Type
Resistive Heaters， Fan-Assisted Heaters， Thermostat-Controlled Heaters (electric heaters thermostat controlled),
Can enclosure heaters prevent condensation?
Yes. By maintaining a stable internal temperature, they keep internal surfaces above the dew point, which effectively prevents moisture condensation that can lead to corrosion or electrical failure.
How is an enclosure heater mounted and wired?
Most models offer DIN rail mounting or panel mounting, and wiring is typically straightforward with terminal blocks or pre-wired cables. Always follow the wiring diagram and consult a qualified electrician for installation.
