Special Application Packaged Blowers - EMI/RFI Shielding

2influenzmaschine-113243_1920.jpg

The Kooltronic EMI/RFI shield conforms to the latest technology in attenuation of electromagnetic interference. The KPR Series combines this shield with Standard Twin Packaged Blowers. This shielded front end can be incorporated into 

the entire line of Kooltronic Packaged blowers, as an option, with few dimensional changes. This same front end can also be used as an accessory.

Kooltronic achieves a high degree of EMI attenuation by the use of proven techniques and scrupulous production and quality controls. The honeycomb element and copper and tin-plated iron wire gasketing are sandwiched between a plated unitized steel frame and a plated flange welded to the cabinet. These are clamped in place with precision- torqued Allen head cap screws. This permits high clamping pressures for maximum EMI attenuation without distortion. The use of metallic chromate finish on the steel frame and corrosion-protected aluminum honeycomb provides uniform high attenuation and minimum internodal resistance. No conductive plastics are used. A full mounting flange provides a continuous conductive surface for interface with the user's cabinet.

Kooltronic also offers a full line of EMI-Shielded FIlter Grille Assemblies, independent of the blower package. These assemblies can be used at remote inlet or discharge locations, for EMI-protected air paths.

For unusual or higher-level attenuation requirements, or special EMI/RFI problems, consult our Engineering Department.
