DURA VI Full-Inverter Heat Pump: Premium Vertical Efficiency
The top-tier DURA VI heat pumps are latest-generation “Stepless Full Inverter” models, designed to offer maximum thermal efficiency with minimum noise. Featuring an innovative vertical design and a distinct blue aesthetic, the VI range can achieve a COP of 14.7 or higher, guaranteeing the heating of pools and spas year-round, even in extreme winter conditions.
The major difference between the DURA VI and a traditional pump lies in its operational intelligence. While a standard pump (ON/OFF) always runs at maximum power with abrupt starts, the Full Inverter technology of the DURA VI precisely controls the fan and compressor speeds. In “BOOST” mode, it reaches the desired temperature quickly; once achieved, the pump reduces its speed to a constant rhythm, maintaining heated water with drastically lower energy consumption and near-silent operation.
The vertical design of the DURA VI is not just aesthetic; it is a technical advantage. This configuration allows for a larger evaporator around the entire machine, making it more efficient than horizontal models. Additionally, vertical pumps require less clearance for airflow and expel cold air upwards, avoiding discomfort in surrounding leisure areas. Installation is further simplified by the FullFlow™ system, which ensures ideal water flow without the mandatory need for a Bypass.
Equipped with NoFrost™ and HotDeFrost™ technology, the DURA VI is prepared to operate at temperatures as low as -10°C. The HotDeFrost™ system is a revolution: it eliminates accumulated frost in approximately 3 minutes through cycle inversion without cooling the pool water, making it the ideal solution for jacuzzis and pools that require rigorous thermal maintenance. All of this is intuitively managed via the Full Color LCD touchscreen or remotely through the DuraLink™ system.
Key Benefits
- Ultra-High COP (14.7): Maximum energy conversion for reduced electricity bills.
- Soft Start: Prevents consumption peaks and protects the home’s electrical installation.
- Absolute Silence: Speed reduction in maintenance mode makes the pump practically inaudible.
- Premium Durability: Titanium heat exchanger and high-quality polymer casing immune to corrosion.

Frequently Asked Questions (FAQ) – DURA VI
Due to Full Inverter technology, the DURA VI can consume up to 50% less energy. While a traditional pump constantly turns on and off, the VI adjusts power to keep the temperature stable with minimal expenditure.
2. Is the NoFrost™ system really important?
Yes. Even in Mediterranean climates, winter nights can reach freezing temperatures. NoFrost™ uses sensors and thermal materials to ensure components do not crack or freeze, protecting your investment.
3. Do I need to install a Bypass with this pump?
Thanks to FullFlow™ technology, the DURA VI allows full water flow with minimal resistance, which eliminates the need for a Bypass in most situations, making assembly cheaper and simpler.
4. How does “Soft Start” mode protect my home?
Traditional pumps can cause “brownouts” when starting. The soft start of the DURA VI ensures that electricity consumption rises gradually, avoiding overloads in the electrical panel.
5. Can I control the DURA VI via smartphone?
Yes. As part of the DuraLink™ range, it can be integrated with the LINK Touch system for total remote control, allowing you to adjust the temperature even before arriving home.
6. Does the vertical design affect noise?
Yes, positively. Vertical pumps are naturally quieter due to the upward airflow and the structure that better isolates Inverter compressor vibrations.
