Reliable Protection Against Pressure Surges<\/h2>\n

These pressure surges would enter the interior of pressure-resistant rail vehicles through the fresh air and exhaust air ducts of the air conditioning systems. When pressure differences occur inside the vehicle, this leads to very unpleasant pressure sensations in people’s ears. Pressure protection systems<\/b> consist of a pneumatically operated pressure-tight closure and an electronic differential pressure measurement, which detects the pressure fluctuation and sends the signal to the pneumatics to close the mechanism when limit values are exceeded.[\/vc_column_text][\/vc_column_inner][\/vc_row_inner][\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”50px”][\/vc_column][\/vc_row][vc_row bg_type=”bg_color” bg_override=”full” bg_color_value=”#F2F2F2″][vc_column][vc_empty_space][vc_row_inner css=”.vc_custom_1776173612698{margin-top: -10px !important;}”][vc_column_inner width=”1\/2″][vc_column_text css=””]The pressure protection systems from Krapf & Lex are based on 15 years of experience
