4-pipe functionality with a 2-pipe distribution system

Even with two-pipe risers, WLHP terminals can operate in both heating and cooling modes, ensuring maximum flexibility to adapt to different occupant needs and building characteristics (building direction, glass surfaces, etc.).

Higher efficiency in the first thermal step

Chillers, cooling towers, or dry coolers used for the first stage operate with water at 30 °C instead of 7 °C, improving energy efficiency and reducing the mechanical load on the machines. Lower consumption also means fewer CO₂ emissions.

Compatibility with cooling towers

The system can be easily combined with closed circuit cooling towers and dry coolers, ensuring stable and sustainable thermal management, even in large buildings.

Savings on the distribution system

Thanks to the neutral circuit temperature (30–35 °C), pipe insulation is not required. This results in a simpler, more economical, and faster-to-install system.

Zero thermal losses

The neutral water temperature in the loop drastically reduces thermal loss, increasing the overall efficiency of the system and reducing operating costs.

Condensate-free solution

The system offers an injection pump kit accessory, eliminating issues related to condensate drain installation or management—particularly useful in buildings where drains are not available or not functional.

Energy recovery

The mixed use of WLHP units makes it possible to recover energy between units operating in cooling and others in heating, delivering additional savings for the primary generators.

Perfect solution for retrofit projects

In existing buildings where traditional fan coils operate at 7 °C and condensate drains have deteriorated, targeted replacement with WLHP units is possible, avoiding invasive work on drains or risers.

Optional domestic hot water production from recovery

The thermal energy transferred by WLHP units to the loop can be recovered to produce free domestic hot water.
