Controlled Temperature on the Mixing Valve
38°C (choose a 10/50°C mixing valve)
45°C or 50°C (choose a 30/70°C mixing valve)
Type of Installation
Select the type of installation based on usage. The flow rate coefficient (simultaneity coefficient) will vary depending on the type:
- Residential use (e.g., apartments, houses)
- Collective use (e.g., hotels, campsites, hospitals, hydrotherapy centers)
- Commercial or public use (e.g., stadiums, gyms, factories, schools, swimming pools, barracks)
Inlet Pressure
Choose an inlet pressure between 1 and 3 bar. This should reflect the dynamic, balanced network pressure at the hot/cold water inlets of the thermostatic mixing valve.
Number of Appliances:
Specify the number of appliances to be supplied with mixed water based on the type of outlet (single outlet or timed flow control):
- Washbasin, shower, bath, and bidet = bathroom
- Sink = individual kitchen
- Washing tub = industrial kitchen
If applicable, specify the required maximum flow rate in liters per minute (l/min), including allowances for future network extensions.
Other indicate the flow
Indicate the flow rate in l/min : indicate the maximum flow rate required in the event of future network extension.
Calculate the Mixing Valve:
Click the *Calculate the Mixing Valve* button to generate the calculation result and determine the correct Ultramix valve size for your application.
- Link to the product category with mixing valves.
- Button to print the parameters and results.
- Parameters entered.
- The total flow rate required by the system if all devices are in simultaneous operation (in l/min).
- The simultaneity coefficient (probability that the devices will operate simultaneously, unless the system is equipped with timed shut-off valves).
- The corrected flow rate in l/min corresponds to the total flow rate x simultaneity coefficient, which determines the size of the mixing valve.
- The Ultramix thermostatic mixing valve best suited to the actual or future installation.
- The flow rate required to the actual or future installation (correspond to the parameters entered previously).
- Nominal diameter of the mixing valve.
