The Thero-90 is an RO appliance designed for domestic households, fitted under the sink to deliver purified, clean water from your kitchen tap. It is a new generation RO system that helps you remove all unwanted substances (heavy metals, chlorine, hardness, bad smells, and tastes) and offers you with the purest water ideal for drinking, washing fruits and vegetables, and cooking meals.
The compact device contains a high-pressure pump and pressure measurements. Under high pressure (about 8 bar), the water is passed over a semi-permeable membrane, where pure water diffuses through the membrane to the permeate outlet, and the concentrate (residual water thickened in salts) runs continuously to the drain. The thero-90 only works in combination with a kitchen sink tap; however, it doesn’t require any further accessories to function, not even a storage vessel that can promote bacterial growth.
To ensure a long service life of the diaphragm, the pump remains idle for approx. 10 seconds after production to thoroughly rinse away the last residual salts. In addition, the device automatically rinses for approx. 30 seconds, every 3 hours of stoppage.
The Thero-90 Pro has some extra measuring probes (conductivity and temperature) and a water meter and offers monitoring and control via an App (requirements for smartphones: minimum Android 7.0 or iPhone 6). In the App you can program the start/stop pressures, read out the operating data, the remaining capacity of the pre-filter, and the alarms. In case of a leak, this alarm is triggered and the LED on the device will flash red.
