Wiska > Prevention of condensation in electronic housing

Germany, Kaltenkirchen – Venting solutions for the electric trade



To prevent condensation in electronic housings and short circuits in sensitive electro-technical installations.

Say goodbye to condensation
Venting solutions by WISKA prevent condensation in electronic housings and short circuits in sensitive electro-technical installations like LED-luminaires. The solutions to solve problems with water condensation in electro-technical installations.
WISKA, supplier for the electrical trade, industry and shipbuilding, presented its comprehensive product range of cable glands and junction boxes at SPS IPC Drives in Nuremberg. One of the particular emphases at Europe’s leading trade fair for electric automation technology, is on the venting solutions supplied by WISKA. They prevent condensation in electronic housings and short circuits in sensitive electro-technical installations like LED-luminaires.


Condensation and risk of corrosion and other damages
Condensation can occur in all areas of electrical installation within tightly-sealed cases that are exposed to changes in temperature, and therefore differences in air pressure between the interior and exterior, despite high IP protection classes. And wherever there is water, there is the risk of corrosion, electrical short-circuits and other damage. These often result in power failures, bottlenecks in supply, and cost-intensive downtime.
Protection against condensation has often been provided in the form of electronic heating ventilation systems, which are expensive and require a high level of maintenance. Or drip-holes in cases, although these also mean the loss of a high protection class. WISKA confronts this challenge with its breathable venting products for pressure equalisation.
The VentGLAND® cable gland and the VentPLUG pressure equalisation unit have a breathable ePTFE membrane, which is watertight and at the same time permeable by air, meaning that it is possible for the pressure between the case interior and exterior to be constantly equalised. That way the formation of condensation is avoided. In addition, the air flow rate can be adapted to customer´s needs, as the pressure equalisation products supplied by WISKA are equipped with different membrane types.


Protection class IP 68 and 69K
VentGLAND® and VentPLUG both have the high protection class IP 68 and 69K, as well as being UV and salt water-resistant, making them suitable for roughest conditions. The cable glands are available in the following materials: plastic, brass and stainless steel. The locking elements are available in brass and plastic, and stainless steel on request.
The venting products supplied by WISKA are used in engineering and craft applications, for example. Light manufacturers, particularly those who produce LED lights, are also making use of VentGLAND® cable glands with increasing frequency, to protect components in light cases. Customers include the shipping and offshore industries, as well as rail engineering companies, keeping their technical systems ready for operation even in severe environmental conditions.
Alongside its venting products, WISKA presented additional cable glands for various areas of use at SPS IPC Drives 2015.
WISKA manufactures electrical equipment, maritime lighting products and CCTV camera surveillance systems for shipbuilding and diverse industries. Founded in Hamburg in 1919, the family company today employs over 230 employees worldwide. The product range includes, for example, searchlights, floodlights, reefer container sockets, cable glands, junction boxes and switches, completed by digital CCTV technology. WISKA operates its own research and development facilities and production plants next-door at its headquarters in Germany and has a global network of representatives and subsidiaries who ensure a quick and effective on-site customer service.
