Minimum power consumption, silent, durable
The INTEWA RAINMASTER Favorit SC meets the strictest efficiency standards of the European Ecodesign Directive for Energy utilizing products (EuP). Herein, strict efficiency standards are prescribed for almost all motors with a capacity from 0.75 to 375 kW that are installed in future. The speed controller regulates the flow rate of the RAINMASTER Favorit SC rainwater system as per your actual needs.
Up to 40 % power saving
Uncontrolled pumps always operate at their maximum capacity without any concern for the actual flow requirement. This can be compared to a car that always runs on full speed and the speed can only be controlled with the brake. Since on most occasions, there are usually only a few consumers simultaneously using water, it is possible to save up to 40 % power by using a speed controller.
| Power consumption | Flow 5 l/min | Flow 10 l/min | Flow 20 l/min |
| without speed controller | 0.656 kWh | 0.733 kWh | 0.777 kWh |
| with speed controller | 0.276 kWh | 0.617 kWh | 0.686 kWh |
| Power saving | 58 % | 16 % | 12 % |
Up to 70% lower noise emmission
As a rainwater system using a speed controller runs at a significantly lower speed to an uncontrolled one, it runs at a much quieter sound level. One RAINMASTER Favorit SC unit emits a sound level of only 45 dBA during the filling of a toilet, compared to 65 dBA by an uncontrolled rainwater system.
Approximately 40 % higher durability
The low speeds, at which the speed-controlled rain water systems predominantly work, lead to significantly less wear and tear on the electronic components and the pump. This increases the durability and operational lifetime of the system by approximately 40 %.
RAINMASTER Favorit SC with speed control – an investment that pays off.
