FAQ - Frequently asked questions about PTC heaters for enclosures and cabinets
What is a PTC heater?
A PTC (Positive Temperature Coefficient) heater is a self-regulating heat source used in electrical cabinets and enclosures to prevent condensation and protect electrical components from moisture damage.
What voltage levels and power ranges are available?
Our PTC heaters are available in several variants:
- Voltage: 24V, 110V and 230V
- Effect: 10W to 650W
This makes it easy to find the right model for your particular application.
Do I need a fan heater?
It depends on the application. For larger cabinets or where better air circulation is required, it is recommended PTC heater with integrated fanFor smaller enclosures or simpler needs, a fanless model works well.
Can I control the heater automatically?
Yes! Our heaters are fully compatible with:
- Thermostats (for temperature control)
- Hygrostater (for humidity control)
- Double-acting thermostats (for controlling both heating and cooling)
Does the heater prevent condensation in the cabinet?
Yes, that is the main purpose. PTC heaters raise the temperature inside the enclosure to keep it above the dew point temperature, which eliminates the risk of condensation.
Is the installation complicated?
No, our heaters have a compact design which makes them easy to install in both new and existing electrical cabinets. They can be installed vertically or horizontally depending on the model.
What accessories are recommended?
For optimal function, you can combine the heater with:
- Ventilation device – removes humid air
- Thermostat temperature control
- Hygrostat – controls the heater based on humidity
In which environments can PTC heaters be used?
They are suitable for:
- Industrial electrical cabinets
- Outdoor enclosures
- Power supply cabinet
- Automation and control systems
In short: all environments where moisture protection is important.
