Spiral Heat Exchangers are a type of heat transfer equipment featuring two concentric, counter-flowing spiral channels, separated by a metal sheet. Ideal for viscous, particulate, or fouling fluids, they provide efficient heat transfer, are compact in size, and require less maintenance compared to traditional shell-and-tube exchangers.

Spiral heat exchangers explained
Spiral heat exchangers (SHEs) are a specialized type of heat exchanger that utilize two parallel spiral channels to facilitate heat transfer. These are structured in such a way that one fluid flows through the inner spiral, while another fluid flows through the outer spiral, all the while separated by a metal sheet. The design enables counter-current flow, which maximizes temperature difference between the two fluids and increases the efficiency of the heat transfer process.
The advantages of SHEs
SHEs are particularly advantageous when it comes to dealing with difficult fluids – those that are viscous, prone to fouling, or have particulates. The single-channel design and continuous curve of the spirals help to create a ‘self-cleaning’ effect, thus reducing the buildup of any material that may impede heat transfer, and making SHEs easier to clean and maintain compared to traditional heat exchangers.
These exchangers are compact and space-efficient, a feature that’s especially beneficial in industries where space is at a premium. Furthermore, they can be used in a variety of applications including, but not limited to, chemical processing, wastewater treatment, petrochemical refining, and HVAC systems.
Despite the initial higher cost, SHEs often provide a lower total cost of ownership due to their durability, lower maintenance requirements, and higher thermal efficiency. However, the optimal use of SHEs depends on specific process conditions including temperature, pressure, fluid properties, and desired heat transfer rate.
Overall, these heat exchangers offer a reliable and efficient solution for heat transfer applications in a range of industries. Their unique design and operation make them a valuable tool for handling challenging fluids and conditions.
