Dehumidification
Control cabinet dehumidifiers: For maximum operational reliability of your systems
Reliably protect your sensitive electronics from the insidious dangers of moisture. A suitable dehumidifier prevents damage caused by condensation and corrosion inside the housing. This ensures a permanently dry climate and significantly increases system availability.
Why is dehumidification so important?
In modern control and distribution cabinets, highly sensitive technology is often exposed to fluctuating ambient temperatures. These are ideal conditions for condensation to form. Our dehumidification solutions lower the relative humidity and specifically reduce the dew point.
Your advantages at a glance:
- Prevention of short circuits: Prevents leakage currents and insulation faults.
- Corrosion protection: Protects contacts and components from oxidation.
- Longer service life: Electronic components last significantly longer in a stable climate.
How it works: Active against moisture
The devices usually operate on the principle of a closed air circuit. The humid indoor air is directed over a specifically cooled surface where the moisture condenses in a controlled manner.
- Condensation formation: Water is actively extracted from the air.
- Safe drainage: The liquid is drained from the housing via a hose and a bulkhead fitting.
- Result: A dry, reliable indoor climate without moisture residue.
Thermoelectric solution: Compact and maintenance-free
The thermoelectric dehumidifier is the ideal choice for enclosures with limited space. With a rated power of 50 W (24 V DC), it achieves a condensation rate of approx. 25 ml/h at 30 °C and 80 % relative humidity.
- Robust and secure: IP56 protection rating (dustproof and waterproof), suitable for indoor and outdoor applications.
- Flexible installation: Easy integration via DIN rail, semi-recessed or wall mounting.
- Optional accessory: A condensate pump can be used if there is no natural slope for drainage.
Conclusion: Long-term protection for your investment
By using certified components (CE, cURus), you can minimize unplanned downtime and reduce maintenance costs for your systems. In combination with control cabinet heaters or cooling devices, you can create a comprehensive climate control concept that provides optimum protection for your automation technology against external climatic influences.

Frequently Asked Questions
Why is dehumidification important in a control cabinet?
Moisture and condensation can cause corrosion, leakage currents, and failures. Dehumidification protects components and increases operational reliability.
How does condensation form in a control cabinet?
Condensation often results from temperature changes, such as between day and night or when the control cabinet door is opened. Outdoor applications and unheated areas are particularly affected.
When should I use a control cabinet dehumidifier?
If moisture, condensation, or corroded contacts occur regularly, dehumidification is recommended. A preventive solution is also advisable for systems with critical availability requirements.
What should I look for when selecting a dehumidifier?
Elevant factors include the control cabinet volume, environmental conditions, and the desired maximum humidity level. Additionally, the type of installation and maintenance requirements play a role.
