The sealing equipment of the entire vehicle is tested and supervised for leakage using our independently developed control system. The entire testing process is carried out through a smoke generator, differential pressure box, and blower fan system. It can achieve leakage testing under a certain static pressure inside the carriage, testing the air output of a certain air conditioning outlet, and testing the air leakage of the outlet when it is closed. Relevant testing data and parameters may be controlled and exported through PLC
