Heaters for the switchboard

Switchboard heaters - a key element of protection against moisture

Switchboard heaters are essential equipment for control cabinets and electrical switchboards.   Their main task is to protect sensitive components from the harmful effects of moisture. At Onninen, we understand the importance of these inconspicuous but key elements. Our wide range of heaters meets the highest standards of quality and reliability.

In everyday practice, we observe a growing interest in switchboard heaters. This is due to the growing awareness of the risks associated with water vapor condensation in electrical cabinets.   A properly selected heater effectively prevents the formation of condensation and corrosion.   This translates directly into longer device life and greater installation safety.

Types of switchboard heaters available in the Onninen offer

Our range includes a wide selection of heaters adapted to various needs. We offer, among others:

• Resistance heaters with power from 15W to 150W
• Heaters for voltage 230VAC and 24VDC
• Models with built-in thermostat or hygrostar
• Explosion-proof heaters

We especially recommend heaters of our own brands: Onnline and FXA.   These products combine high quality workmanship with an attractive price. They were developed based on our many years of experience in the electrical industry.

We often come across questions about the criteria for selecting the right heater. The key parameters are heating power and supply voltage. The dimensions of the cabinet and the environmental conditions in which the switchboard operates should also be taken into account. Our experienced advisors will be happy to help you choose the optimal solution.

Practical applications of switchboard heaters

In our daily work we encounter various challenges related to protecting switchboards from moisture.   We recently completed a project for a large manufacturing plant.   It required securing control cabinets operating in difficult conditions - with high humidity and significant temperature fluctuations.

We used 100W resistance heaters with a built-in thermostat. This solution ensured stable conditions inside the switchboards throughout the year. The customer appreciated the significant reduction in failures caused by corrosion of components. This resulted in increased reliability of the entire production line.

In the case of smaller installations, e.g. in residential buildings, lower power heaters are more effective.   For switchboards in basements or garages we recommend 15W-30W models.   They provide sufficient protection against periodic increases in humidity without generating significant energy costs.

It is worth paying attention to heaters with a built-in hygrostar. They only start when humidity exceeds a set level. This is an energy-saving solution, especially useful in locations with variable weather conditions.

Innovations in the field of switchboard heaters

The technology of switchboard heaters is constantly developing. At Onninen, we follow the latest trends and introduce innovative solutions to our offer.   PTC (Positive Temperature Coefficient) heaters are becoming more and more popular.   They are characterized by variable heating power that adapts to the ambient temperature.

Another interesting solution are heaters equipped with a fan. They provide even heat distribution throughout the cabinet. This is particularly important in the case of large switchboards with a dense arrangement of components. Heaters of this type effectively eliminate local zones of increased humidity.

Our offer also includes heaters in Ex version, designed for explosion hazard zones. They meet strict safety standards. They are used, among others, in the chemical or gas industry.

Our experience shows that investing in high-quality switchboard heaters pays off quickly.   This translates into reduced service costs and extended service life of electrical installations. At Onninen we offer comprehensive support - from selecting the right heaters to their professional installation.

We invite you to contact our specialists. We will help you choose the optimal solution, taking into account the specifics of your installation and the operating conditions of the switchboards. We guarantee professional advice and quick order fulfillment. The safety and reliability of your electrical installations are our priority.
