03 · DESCRIPTION
Purpose and operating principle
The monoblock design merges both stages of two-stage DHW into a single dual-pass plate heat exchanger separated internally by a baffle. This delivers two-stage energy efficiency with a smaller footprint and simplifies the piping — two stages in one device. It is used at facilities with limited substation space.
04 · APPLICATIONS
Where the module is used
- Facilities with limited substation space
- Retrofit of substations in constrained conditions
- Energy-efficient projects with compactness requirements
05 · ADVANTAGES
Why ANHEL®
Factory assembly, quality control and our own automation.
