EvoFlat 4.0 M - Demand control
Product
The EvoFlat 4.0 M combined with the ICON2 floor heating controller provides intelligent, demand controlled regulation for apartment and room heating. Using a self‑learning, patented algorithm, the system continuously evaluates actual heat demand and automatically adjusts the supply temperaturefor optimal comfort, energy efficiency, and hydraulic balance. It responds quickly to changing conditions, integrates seamlessly with modern heat sources, and supports remote monitoring and control via the Ally app. Fully compliant with European energy performance standards, it offers a scalable, future‑proof solution for both small and multi‑zone installations.
The innovative unit sets new standard. It consists of functional blocks made of a specially reinforced PPS composite material. This makes the station extremely lightweight and limits internal heat emission. The smooth surface reduces the risks of scaling and clogging. All components are assembled with newly designed click‑fit connections.
Primary side (DH)
The flat station is equipped with two differential pressure controller and a central strainer. A summer bypass keeps the supply line warm during standstill. This ensures a fast response time for DHW during the summer. The bypass is thermostatically controlled.
Heating (HE)
Supply temperature is adjusted according to the actual heating demand from all connected rooms, ensuring optimal comfort. The controller identifies misbalanced loops and adjusts the opening cycles according to this (automatic hydraulic balancing). A safety thermostat closes the flow at 55°C. A highly efficient circulation pump is installed. A bathroom radiator or towel dryer can be connected using an optional high‑temperature connection set.
Domestic hot water (DHW)
Four sizes of heat exchanger are available to cover all requirements from 45 kW up to 70 kW. The Evoflat 4.0 M is equipped with an intelligent controller that regulates the supply side flow based on the domestic hot water temperature and the volume of water drawn. The station features an integrated differential pressure controller on the supply side of the domestic hot water heating system. This eliminates the need for hydraulic balancing of the station. If necessary, the station can be expanded with a hot water circulation set.
EvoFlat 4.0M
Danfoss EvoFlat 4.0 station is particularly suitable for multi family buildings with central heat generation or district heating.
The innovative unit sets new standard. It consists of functional blocks made of a specially reinforced PPS composite material. This makes the station extremely lightweight and limits internal heat emission. The smooth surface reduces the risks of scaling and clogging.
All components are assembled with newly designed click-fit connections. Compared to conventionel substations with pipes and screw connections, this new connection technology does not require retightening during installation and commissioning.
