Indoor, Outdoor, Offshore – Control Cabinets Must Be Tightly Sealed!

Control cabinets are extremely important for modern processes and production facilities. They serve as control centers in which important electronic components of machines and systems must be reliably protected from moisture, dirt, heat, and cold. For this challenging task, high-performance sealing foams made of polyurethane and silicone, developed and produced by RAMPF Polymer Solutions, are ideally suited.

Out of the rain into the factory hall

Control cabinets protect those electric/electronic components that are not directly placed in a machine but in an empty housing. Typical applications include:

  • Switchboards for production plants
  • Paint shops
  • Charging stations for electric vehicles
  • Power distribution boxes for power pylons
  • IT housings
  • PC cabinet systems

Depending on where they are used, control cabinets are exposed to different influences. While the interior of control cabinets in a factory hall, for example, have to be protected against dust, oils, and caustic vapors, outdoor control cabinets are exposed to UV radiation, heat, frost, and rain.

Sealing foams made by RAMPF – the go-to-solution

Since the mid-1980s, most control cabinets are being equipped with a machine-applied, two-component polyurethane gasket (RAKU® PUR), which protects the interior of the control cabinet against external influences.

The development of CNC and subsequently of robot technology has enabled the in-situ application of sealing systems. From this, the so-called "Formed In Place-Foam Gasket" technology (FIPFG) was developed, a low-pressure foaming process for the application of sealing foams.    

This technology facilitates the automated application of the sealing foam, sealing the components of control cabinets cost-effectively and to the highest consistent quality in large quantities and with a wide variety of geometries. After the foam has cured, it is firmly connected to the component and ready for further processing.

In Schaltschränken werden zumeist die Türen abgedichtet, die 2K-PUR-Dichtungen von RAMPF Polymer Solutions kommen jedoch auch in Fenstern, Lüftern, Schlosszylindern und elektrischen Gehäuseeinsätzen zum Einsatz.

Stärken der Dichtungsschäume von RAMPF Polymer Solutions   

Indoor-, Outdoor- und Offshore-Schaltschränke müssen entsprechend ihrer Einsatzumgebung unterschiedliche Anforderungen erfüllen. Dementsprechend sind die Dichtungsschaumsysteme von RAMPF Polymer Solutions auf die jeweiligen Eigenschaftsprofile optimiert.

Indoor / Allgemeine Anforderungen an Dichtungssysteme für Schaltschrankanwendungen:

  • Gute Haftung auf lackierten Oberflächen
  • Gute mechanische Festigkeit, insbesondere in Scharnierbereichen
  • Gute Chemikalienbeständigkeit
  • Einfache Verarbeitung über 2K-Misch- und Dosieranlage

Zusätzliche Anforderungen an Dichtungen für Outdooranwendungen:

  • Abdichtgüte bis IP 68, kein Wassereintritt
  • Hitze, Frost-, UV-Strahlen-, Hydrolyse- und Fungizidbeständigkeit

Zusätzliche Anforderungen an Dichtungen für Offshoreanwendungen:

  • ATEX (Explosionsschutz)
  • Salzwasser- und UV-Beständigkeit

Sebastian Kärcher, Market Segment Manager Sealing Systems bei RAMPF Polymer Solutions:

Die Leistung und Komplexität elektrischer/elektronischer Komponenten nimmt rapide zu – und somit auch die Wichtigkeit von Schaltschränken. Mit unseren RAKU® Polyurethan- und Silikondichtsystemen bieten wir Schaltanlagenbauern hochqualitative Produkte, die flexibel in der Formgebung und einfach zu verarbeiten sind.

Two-component polyurethane sealing foams made by RAMPF Polymer Solutions are used predominantly for sealing control cabinet doors. However, windows, fans, lock cylinders, and electrical housing inserts can also be effectively sealed by these high-performance foam systems.

Sealing systems made by RAMPF – the advantages   

Indoor, outdoor, and offshore control cabinets must meet different requirements depending on their operating environment. And that is why sealing foams made by RAMPF Polymer Solutions are tailor-made for the respective application areas.:

Indoor / General requirements for sealing systems for control cabinet applications

  • Good adhesion to painted surfaces
  • Good mechanical strength, especially in hinge areas
  • Good chemical resistance
  • Simple processing via two-component mixing and dispensing system

Additional requirements for outdoor applications

  • Sealing quality up to IP 68, no water ingress
  • Resistance to heat, frost, UV radiation, hydrolysis, and fungicides

Additional requirements for offshore applications

  • ATEX  (Explosion protection)
  • Saltwater and UV resistance

Sebastian Kärcher, Market Segment Manager Sealing Systems bei RAMPF Polymer Solutions:

The performance and complexity of electrical/electronic components are rapidly increasing – and so is the importance of control cabinets.  With RAKU® polyurethane and silicone sealing systems, we offer control cabinet manufacturers high-quality products that are flexible in design and easy to process.
