EvoFlat 4.0 PRO W

The Danfoss EvoFlat 4.0 PRO W is an electronically controlled flat station designed to regulate the temperature of domestic hot water. It is particularly well-suited for use in multi-family residential buildings with central heating systems.
Equipped with an advanced electronic controller and specially developed actuator, the unit ensures precise temperature regulation, while all relevant operational data can be accessed online. Cold water and heat meters can be read and displayed simultaneously via the M-Bus interface.
This innovative solution sets new industry standards. The functional blocks are manufactured from reinforced PPS composite material, making the station lightweight and reducing internal heat emissions. The smooth internal pipe surfaces minimise the risk of deposits and blockages.
All components are assembled using advanced Click-Fit connections. In comparison to conventional stations with pipe and screw fittings, this modern connection technology eliminates the need for retightening during installation and commissioning.

Primary side
The flat station is equipped with a differential pressure regulator and a strainer. A summer bypass function maintains the supply line temperature during idle periods, ensuring a rapid response time for domestic hot water production. The bypass can be operated continuously or according to a weekly schedule.

Domestic hot water ( DHW)
Four heat exchanger sizes are available, covering capacities from 37 kW to 80 kW.
The EvoFlat 4.0 PRO W is equipped with an actuator for precise regulation of the domestic hot water temperature. This actuator adjusts the primary-side flow rate according to the hot water temperature and the tap volume.
The station incorporates an integrated differential pressure regulator on the primary side of the domestic hot water heating system, eliminating the need for hydraulic balancing between the station and the primary side.
If required, the station can be expanded with a DHW circulation set.
