Purple Heat Exchangers’ volume heat exchangers offer fast, hygienic hot water delivery using floating coil technology. Ideal for schools, hotels, and hospitals.
The Volume Heat Exchanger from Purple Heat Exchangers is designed for rapid, efficient hot water production using a built-in floating coil system. As cold water enters the tank, it is heated in layers by the floating coil, which maintains optimal heat transfer while reducing heat loss and increasing response speed. This system ensures consistent water temperature, no cold zones, and excellent water quality – making it an ideal choice for sanitary hot water supply in hospitals, hotels, schools, and residential facilities.
Features
Quick Start-up
Hot water is delivered almost instantly to the outlet without needing to heat the entire tank volume, thanks to the top-floating coil design.
High Heat Transfer Efficiency
Dynamic heating with high-conductivity coils and constant flow ensures a fast and stable heating process.
Not Easy to Scale
Turbulent fluid motion prevents fouling on coil surfaces, maintaining efficiency over time.
No Cold Water Zone
The tank maintains a uniform temperature throughout, eliminating cold zones and improving water utilisation.
Good Water Quality
Uniform heating and constant circulation reduce bacterial growth risk, even with long dwell times.
