CLIP-ON KNITTED WIRE MESH RFI/EMI SHIELDING GASKET STRIP INTRODUCED
Kemtron has launched a new clip-on knitted wire mesh RFI/EMI shielding gasket strip. This is a very flexible, easily compressible, sponge EPDM tubular
or bulb type gasket strip with a steel spring clip covered with a double knitted wire mesh layer for RFI/EMI shielding. The clip-on gasket strip is supplied by EMKA, which ensures superior
quality and consistency of its gasket strips. Kemtron double knits the wire mesh over the strip at its Braintree factory. This clip-on seal provides a good RFI/EMI shield for enclosures and
electrical cabinets. The soft hollow bulb profile requires low closure force and makes the product particularly suitable for door applications where frequent opening and closing is required. The clip-on gasket is easy to fit and will bend up to 90˚. Furthermore, the knitted wire mesh gives very low contact resistance between mating surfaces ensuring good shielding. The choice of wire mesh material available also allows for a good
galvanic match with mating flanges, thereby limiting the possibility of corrosion between gasket and flange. Knitted wire choices are monel, stainless steel, aluminium and tin plated copper clad steel. Kemtron manufactures RFI/EMI shielding gaskets and components for all enclosure applications.

ENERGY SAVINGS IN ENCLOSURES
Saving energy within an enclosure may not be as high a priority as keeping the equipment cooled with the correct combination of fans and outlet filters, but savings can easily be made.
Enclosure thermostats The first and most simple product to achieve energy savings is a normally open thermostat. Using a thermostat ensures that the fan is only running when actually needed. However, consider then the fact that the filters within the fitted filter fans will have an extended life, therefore reducing the need for replacement. Additionally, the lifetime of the fans will be extended if they are only running when needed.
LED Lighting LED enclosure lights are fast becoming the norm these days – they are more reliable, robust and use less energy. There are additional benefits from the fact that they generate very little heat and require near zero maintenance once fitted. The environment will also benefit as breaking a standard florescent tube releases toxic mercury as well as phosphor.
EC cooling fans The latest energy saving EC fans are beginning to make their presence within enclosures. A standard 120mm x 38mm AC panel fan uses approximately 22W, whereas the equivalent latest EC type uses only 4W. Based on a calculation of 0.14p per kWh, running 2 x 22W fans for 24 hours a day would cost £53.16 per year. Using the same calculation for the 4W EC fan would cost £9.60 per year. The savings are significant, payback is quick and, more importantly, ongoing for the rest of the product’s lifecycle.
