H type shell and tube heat exchangers are an economic solution for small CH and DHW systems.
The HEXONIC H shell and coil heat exchanger is an economic solution for small CH and DHW systems. It extends the shell and tube exchanger range with the smallest exchangers built on a tube coil design, combining high performance with compact size relative to heat exchange surface.
The H series was developed to meet the requirements of the smallest industrial systems and heating substations, especially where plate exchangers cannot be used for various reasons such as high contamination or aggressive environments. Versions with threaded and flanged connections are available to maximise adaptation to local conditions and facilitate installation.
Key Features
- Economic solution for small systems:The H series is positioned as a cost-effective option for small CH and DHW systems.
- Compact size: High performance combined with compact size makes the H series well suited to low power systems.
- Space-saving installation: Compact dimensions and the possibility of vertical installation reduce the space needed for installation.
- High efficiency: A higher heat exchange coefficient is achieved thanks to corrugated tubes that increase flow turbulence and intensify heat exchange.
- Suitable where plate exchangers cannot be used: The H series is recommended for applications involving high contamination or aggressive environments.
- Flexible connection options: Versions with threaded and flanged connections are available for better adaptation to local installation conditions.
- Standards compliance: The exchanger is made according to PED.

Frequently Asked Questions
The HEXONIC H heat exchanger is designed as an economic solution for small CH and DHW systems. It is also intended for the smallest industrial systems and heating substations.
The H series is especially suitable where plate exchangers cannot be used, for example in cases of high contamination or aggressive environments.
The H series uses a tube coil design and can include corrugated tubes, which increase flow turbulence and intensify heat exchange. This gives high performance relative to the exchanger’s compact size.
Versions with threaded and flanged connections are available to adapt the exchanger to local conditions and facilitate installation.
