In the first half of 2026, Metrostav CZ completed another stage of work aimed at improving the cooling systems of diesel generators. The cooling water piping for the machines in the 3rd Division’s 1st and 2nd production units was replaced.

Required verification of flow measurement at both diesel generators was carried out at the end of June 2026. The ultrasonic flow meter with clamp-on sensors was used for discharge measurement as in year 2025.

Although the exact time of tests was changed several times due to technical difficulties, the measurement was finally carried out successfully. The test results at both machines confirmed that the minimum required flow rate had been exceeded.
