The capsule element makes the difference: Invented in 1924 and a lasting success story with millions and millions in use. The capsule element now works as a control membrane in the new Vario-DP valve range to provide the correct water volume to the radiator and to ensure maximum protection against pollution. With this principle, hydraulic balancing becomes fully automatic and reliable.
   

Hydraulic balancing at its best: With 340 l/h, the universal valve range Vario-DP offers a high reserve and optimum protection against pollution.

With the adjustable Vario-DP dynamic thermostat valves, heating system professionals can perform hydraulic balancing quickly and efficiently. A standard capsule element serves as the basis of the system. Integrated into the valve insert, it automatically limits the water volume adjusted at the valves – independent of pressure variation in the heating system. Therefore, Vario-DP ensures that the right water volume is always supplied to the radiator, regardless of the number of open or closed thermostat valves in the system, for optimum comfortable temperature in the room.

Full functionality even with poor water quality

With AFRISO Vario-DP, the key issue of heating water quality, the contamination with dirt particles and, as a result, a possible malfunction of radiator valves is a matter of the past! Since the control membrane is installed directly in the dynamic valve insert and the valve spindle is used as the pressure sensor, there are no additional control components which might be subject to pollution. In addition, Vario-DP operates with a standard valve gasket and does not require additional dirt filters which need extensive maintenance. Clogging and subsequent failure due to particles can therefore be excluded. Considering the uniquely high flow rate of up to 340 litres per hour, you are extremely flexible in single-family and two-family houses, but also in residential construction - and even in special cases you have a dynamic valve with a sufficiently high reserve at all times.

Complete range

The Vario-DP product range is available with nominal diameters of DN 10, DN 15, DN 20 and in the standard types angled, straight, axial and angled-angled as thermostat valve body and as combination block or thermostat combination block for radiators with centre connection in dual pipe systems. It features a continuously adjustable range from 20 l/h to 340 l/h. The gunmetal fittings have a control range from 20 to 50 kPa; they are suitable for pressures of up to 10 bar and for temperatures of the medium of up to 120 °C.

More benefits for even higher heating cost reductions

AFRISO also offers smart thermostat heads for everyone interested in making hydraulic balancing even more efficient. If Vario-DP units are networked in the AFRISO smart home system, you can implement numerous intelligent functions (such as holiday mode) and save even more energy.

If Vario-DP are networked in the AFRISO smart home system, the temperature can be intelligently adapted to the type of use of the rooms (for example, night mode, holidays, "window open - heating system off") which further reduces the heating costs.
