S type shell and tube heat exchangers are a perfect solution for low power systems.
The HEXONIC S shell and coil heat exchanger is a compact solution designed for low power systems. Its small dimensions and compact connection layout make it especially suitable wherever limited installation space or low system power prevent the use of larger exchangers.
The S type exchangers are special versions of the smallest JAD exchanger models. In addition to their more compact size, they allow reduced pressure losses on the shell side while maintaining high flow speed. They are available in a regular version with perpendicular connections and in an X-shaped version that combines the advantages of JAD X exchangers with the compact S-series form factor.
Key Features
- Space-saving design: The compact size of the exchanger and the possibility of vertical installation reduce the space necessary for installation.
- Low operating costs: The X-shaped design of the connections and corrugated coil tubes make the exchangers more resistant to deposits.
- High efficiency: A higher heat exchange coefficient is obtained thanks to corrugated tubes, which increase flow turbulence and intensify heat exchange.
- Low shell-side pressure losses: The S type allows decreasing pressure losses on the shell side while maintaining high flow speed.
- Flexible connection options: Available in regular versions with perpendicular connections and X-shaped versions for different installation needs.
- Compact alternative to larger exchangers: The S series is designed specifically for systems where larger exchanger sizes are not practical.
- Standards compliance: Manufactured according to PED and ASME.

Frequently Asked Questions
The HEXONIC S heat exchanger is designed for low power systems where compact size is critical. It is especially suitable where limited installation space or low system power prevent the use of larger exchangers.
The S type is a special version of the smallest JAD exchanger models. It offers a more compact size, reduced shell-side pressure losses, and maintains high flow speed, making it better suited to smaller systems.
The S series is available in a regular version with perpendicular connections and in an X-shaped version that combines the advantages of JAD X exchangers with the compact S-series design.
HEXONIC states that the X-shaped design of the connections and corrugated coil tubes make the exchangers more resistant to deposits, which helps lower operating costs over time.
