Abstract
A method of positively indicating leaks in the heat transfer surface area of a heat exchanger between the normally separate fluid paths denoted by side (A) and side (B) arranged in a heat exchange relationship is disclosed. The method comprises: PA1 placing a detector gas or gas mixture on one side; PA1 placing a carrier or entraining liquid in the other side; PA1 applying a positive pressure differential between detector gas and carrier fluid; and PA1 detecting entrained bubbles within the carrier fluid.
