Heat Exchanger Service and Manufacturer In Canada

The purpose of a heat exchanger is to transfer heat between two or more fluids (typically gases and/or liquids)  to regulate temperatures during production. These essential industrial components facilitate the efficient exchange of thermal energy without allowing the fluids to mix. Heat exchangers operate on the principle of thermal conductivity, where heat naturally flows from areas of higher temperature to areas of lower temperature. Heat exchangers are crucial in many industrial applications including power generation, oil/gas production and chemical processing. By controlling temperatures, heat exchangers help maintain optimal operating conditions for equipment and processes, improve energy efficiency by recovering waste heat, and ensure product quality in temperature-sensitive manufacturing operations. Heat exchanger designs can vary widely depending on specific application requirements, efficiency needs, and space constraints.

Detecting a leaking heat exchanger requires attention to several key indicators. Visual indicators with the exchanger may reveal obvious leaks. As well, unusual odors around the exchanger  may also provide a clue that small leaks are present, many times in gas form.  Many times, an exchanger may need to be by-passed and opened up to determine if there is a leak. In this case, to ultimately determine if there are any shell or tube side leaks, a hydro test is completed where a medium (water or glycol mix) may be pressured up and the contractor will monitor the pressure of the system to see if it remains steady. If the pressure in the circuit declines over time, then a leak is confirmed.  A non-destructive examination (NDE) will then be ordered to locate the leak if the leak is not obvious. There are many hazards that are considered when managing leaking heat exchangers.  These include environmental, safety, heat exchanger issues that may result in production issues and operating costs. 

When a heat exchanger begins to fail, it can create both production performance issues and potential safety hazards. When shell or tube side components begin to foul or scale for instance, heat exchange is negatively impacted and production costs, production efficiency or production losses can occur.  Heat exchanger efficiency can drop significantly as the failing exchanger can no longer efficiently transfer heat between fluids, leading to increased energy consumption and inconsistent temperatures. System performance becomes erratic, with frequent cycling and potential shutdowns as safety mechanisms detect abnormal operating conditions. In pressurized systems, fluid leakage may occur, potentially causing contamination between previously separated fluids. The most serious consequence, particularly in combustion applications, is the possible release of noxious and/or combustion gases into the air stream. This creates a significant safety hazard that can lead to unacceptable safety concerns. Additional complications include accelerated wear on other system components as they compensate for the failing exchanger, leading to cascading failures if not addressed promptly.
