"David" – smart under-sink water chiller for Shabbat and weekdays (approved by the Zomet Institute)

The "David" under-sink water chiller is a unique solution of its kind in Israel, combining advanced technology with a full halachic solution. The system operates normally on weekdays and automatically switches to Shabbat mode – with mehadrin kashrut and official certification from the Zomet Institute. A solution tailored to the needs of religious and traditional families, letting you enjoy cold, filtered water on Shabbat without concern.

Key benefits

• Automatic mehadrin Shabbat mechanism — switches to Shabbat mode on its own with no intervention needed, with full halachic certification from the Zomet Institute.
• High output for families and hosting — provides filtered cold water (down to 4 °C) at a rate of about 100 glasses per hour – suitable for the Shabbat table, hot summer days and hosting many guests.

• Hygienic stainless steel casing — the unit is built of quality materials that keep the water sterile and high-quality over time.
• Expandable to hot/cold — you can upgrade and add a dedicated water heating unit to the system (note: the heating unit is not suitable for Shabbat use) at an extra cost.
