Patent abstract
A method for detection of leaks in a plate pack heat exchanger having respective discrete first and second flow paths in mutual thermal contract comprises connecting a helium detector probe at one end of the first flow path and an air compressor means at the other end of the first flow path, introducing helium to the second flow path, allowing air to pass through the first flow path under the influence of the compressor means and detecting any helium present therein by the helium detector probe, the pressure of the second flow path being higher than that of the first flow path.
