Heat exchangers are devices designed to facilitate the transfer of heat between two fluids that are at different temperatures while preventing them from mixing. This sets them apart from mixing chambers. In the realm of industrial engineering, the significance of understanding heat exchangers has grown substantially. They play a critical role in the design, operation, and maintenance of various systems, including heating and air-conditioning systems, vehicle engineering, power plants, refrigeration, chemical processes, and industrial process engineering. This course primarily focuses on procedures for operating heat exchangers, as well as maintenance and inspection techniques. Participants will gain hands-on experience in disassembling and assembling different types of heat exchangers.

Course Objectives:

To provide the delegate with a detailed knowledge of the principles and engineering practice of the subject of heat exchangers in the following areas:

Types of heat exchangers
Principles of heat transfer applied to different types
Design of heat exchangers
Heat exchanger operation principle
Heat exchanger maintenance

Who Should Attend?

Maintenance and operation engineers, supervisors, and technicians. Practicing engineers from the mechanical, chemical and process industrial areas who have an interest in understanding and improving their knowledge of the subject of heat exchangers so as facilitate an improvement in the efficiency of plant processes. Plant operators, designers, and managers will find this course of crucial importance not only to enhance their awareness of the conservation of both local and international energy resources but also to provide the plant with more efficient means of heat exchange
