The shell-and-tube design offers several distinct advantages for glycol water heaters, making it one of the most widely used types in industrial and HVAC applications:
Provides a large heat transfer surface area due to multiple tubes, allowing effective heat exchange between the hot fluid (steam, hot water, or thermal oil) and the glycol-water mixture.
Can achieve close temperature approaches in counterflow arrangements, maximizing heat recovery.
Supports counterflow, parallel flow, or crossflow configurations.
Flow arrangement can be optimized to maximize temperature difference and efficiency depending on application requirements.
Can withstand high pressures and temperatures on the shell or tube side.
Suitable for industrial applications, including process heating and district heating systems.
Tube bundles can be removed, cleaned, or replaced if fouling occurs.
External access allows visual inspection and chemical cleaning, extending service life.
Can be designed for small or very large heat loads, simply by increasing the number of tubes or the shell diameter.
Multiple units can be installed in parallel for modular expansion.
Compatible with a wide range of fluids: glycol-water mixtures, oils, brines, or other heat transfer fluids.
Materials can be selected to resist corrosion or chemical attack from the fluid.
Can tolerate thermal shocks and minor flow variations better than plate-type or finned-tube heat exchangers.
Less prone to mechanical damage from pressure surges or vibration.
Summary:
The shell-and-tube design combines high efficiency, durability, flexibility, maintainability, and scalability, making it ideal for glycol water heating in industrial and HVAC applications. Its ability to handle a variety of fluids and pressures also makes it highly versatile compared to other heat exchanger types.
