How a 100W heater for the enclosure prevents condensation

Temperature Control and Dew Point
You want your electrical enclosure to stay dry, right? That’s where a 100W heater for the enclosure comes in. This heater works by keeping the inside temperature just a bit higher than the dew point. When the temperature inside the enclosure stays above the dew point, water vapor in the air can’t turn into droplets. That means no condensation forms on your sensitive equipment.
Here’s a quick look at how the process works:
| Function | Description |
|---|---|
| Heat Generation | The heater generates heat to maintain a temperature above the dew point. |
| Temperature Regulation | It keeps the internal temperature several degrees higher than the outside air. |
| Moisture Prevention | By stopping the temperature from dropping below the dew point, it blocks moisture buildup. |
You don’t have to worry about guessing the right temperature. Linkwell Enclosure Heaters come with precise thermostats. These thermostats turn the heater on and off as needed, so you get steady protection without wasting energy.
Moisture Risks in Control Cabinets
Condensation is more than just a little water. It can cause big problems in your control cabinets. Moisture can lead to rust, corrosion, and even short circuits. That’s why you need a reliable solution.
A 100W heater for the enclosure helps you avoid these risks by keeping humidity under control. Take a look at what the heater does for you:
| Function | Description |
|---|---|
| Humidity Regulation | The heater keeps relative humidity low to stop condensation. |
| Temperature Control | It makes sure the temperature never drops below the dew point. |
| Damage Prevention | It protects your equipment from corrosion and electrical shorts. |
You also want to know your heater is safe and built for tough jobs. Linkwell Enclosure Heaters hold top certifications for industrial use:
| Certification | Description |

With these features, you can trust your enclosure stays dry and your equipment stays safe.
Heater effectiveness factors
Enclosure Size and Material
You need to match your heater to your enclosure. A small box heats up fast, but a large cabinet needs more power. Metal enclosures lose heat quicker than plastic ones. If you use a 100W heater for the enclosure, it works best in medium-sized cabinets made of metal or plastic. Always check the size and material before you choose your heater.
Ambient Conditions and Humidity
Your environment matters a lot. If you place your enclosure in a damp or cold area, condensation becomes a bigger problem. Condensation forms when the temperature drops below the dew point. This usually happens when humidity is around 65% or higher, especially if the enclosure surface is colder than the air. You should always think about where you install your cabinet and how much moisture is in the air.
Tip: If your enclosure sits outdoors or in a factory with lots of temperature swings, you need to pay extra attention to humidity and temperature changes.
Insulation and Airflow
Good insulation keeps the heat inside your enclosure. If you have high-quality insulation, your heater does not need to work as hard. This helps your 100W heater for the enclosure keep a steady temperature and protect your electronics from moisture and frost. Make sure you seal any gaps and check for drafts. Airflow also matters. If air moves well inside the cabinet, heat spreads evenly and keeps all your components safe.

Is 100W enough for your enclosure?
Sizing Calculation and Rule of Thumb
You want to know if a 100W heater for the enclosure will do the job. The answer depends on your cabinet’s size, how much you want to raise the temperature, and how well your enclosure holds heat. You can use a simple formula to estimate the wattage you need:
Wattage (W) ≈ Cabinet Volume (m³) × Temperature Rise (°C) × Insulation Factor
- Cabinet Volume: Measure the inside length, width, and height in meters. Multiply them together.
- Temperature Rise (ΔT): Figure out how many degrees warmer you want the inside compared to the coldest outside temperature.
- Insulation Factor: Use 10 for well-insulated cabinets, 15 for average, and 20 for poor insulation.
Here’s a quick reference table to help you see how much wattage you might need based on temperature rise and insulation:
| Temperature Rise (°F) | Insulated Wattage (W) | Uninsulated Wattage (W) |
|---|---|---|
| 20°F | 10 | 30 |
| 40°F | 15 | 55 |
| 60°F | 20 | 90 |
| 80°F | 30 | 110 |
| 100°F | 35 | 135 |
| 120°F | 40 | 165 |
| 140°F | 45 | 190 |
