3 in 1 Digital Water Tap
One Digital Faucet, Three Filtered Water Options
The 3 in 1 digital water tap combines filtered boiling water, filtered chilled water, and filtered room-temperature water in one compact under-counter drinking-water system. Instead of installing separate faucets and appliances, the system connects one digital touch faucet to a 4.0L digital boiler tank, 2.0L chilled-water tank, and UF filtration system.
The digital faucet provides temperature control, preset water volumes, and safety functions from a single interface. Depending on the selected mode, users can dispense filtered water from 45°C to 98°C, chilled filtered water from 3°C to 8°C, or filtered room-temperature water.
For kitchen brands, water filtration companies, appliance manufacturers, plumbing distributors, hospitality suppliers, and private-label buyers, this configuration provides a practical platform for developing a branded 3 in 1 digital water tap system.
3 in 1 Digital Water Tap: Three Drinking-Water Functions
The system is built around three dedicated drinking-water functions:
| Function | Water Type | Temperature Range | Main Application |
|---|---|---|---|
| Digital hot water | Filtered heated water | 45–98°C | Tea, coffee, cooking and hot drinks |
| Digital chilled water | Filtered chilled water | 3–8°C | Drinking and food preparation |
| Filtered water | Filtered room-temperature water | Ambient | Everyday drinking |
The system combines the faucet, boiler, chiller, and filtration components under the counter, keeping the kitchen worktop visually clean.
The basic water-treatment route is:
Incoming water → UF filtration → hot/chilled/ambient drinking-water functions → digital faucet
The exact internal waterway arrangement should be confirmed against the final model configuration.
4.0L Digital Boiler Tank for 45–98°C Filtered Hot Water
The 4.0L digital boiler is the heating core of the system.
Unlike a simple kettle, it is designed to work continuously with the digital faucet and provides selectable water temperatures rather than one fixed boiling point.
14 Preset Temperature Settings
The digital boiler provides 14 preset temperature settings:
45°C / 55°C / 65°C / 75°C / 80°C / 85°C / 90°C / 91°C / 92°C / 93°C / 94°C / 95°C / 96°C / 98°C
This gives the user more control over different drinking and food-preparation applications.
For example:
Lower temperatures can be used for warm drinking water.
75–85°C settings are suitable for many tea and beverage applications.
Higher settings provide near-boiling water.
98°C is the maximum preset temperature supplied for this configuration.

Why the 4.0L Digital Boiler Matters
The tank is not simply a heating container.
Several details have been incorporated to support everyday use:
±0.5°C Temperature Control
The supplied specification gives temperature accuracy within 0.5°C. This is useful when users want repeatable temperatures rather than relying on a kettle's variable heating cycle.
SUS304 Food-Grade Water Tank
The water-contact tank is specified as SUS304 food-grade stainless steel.
The heating system also uses stainless-steel elements and sensors, while the filtration stage is positioned to help protect the boiler from incoming water impurities.
10–12 Minute Initial Heating
The supplied initial heating time is approximately 10–12 minutes, depending on inlet-water temperature.
After the initial heating cycle, the specified reheating time is approximately 3–5 minutes, again depending on incoming water conditions.
Open-Vent, Non-Pressure Design
The boiler uses a non-pressure/open-vent design with safety provisions.
This is an important specification for importers and engineering teams because the boiler architecture affects installation requirements, plumbing design, safety assessment, and certification.
2.0L Chilled Water Tank for 3–8°C Filtered Water
The cold-water side uses a dedicated 2.0L chilled-water tank.
Instead of relying on ice or a household refrigerator, the under-counter chiller provides chilled filtered water directly through the digital faucet.
Chiller Technical Specifications
| Parameter | Specification |
|---|---|
| Chilled-water capacity | 2.0 L |
| Rated voltage | 220–240V |
| Frequency | 50Hz |
| Cooling power | 120W |
| Chilled-water temperature | 3–8°C |
| Refrigerant | R600A |
| First cooling duration | Approx. 25 min |
| Recooling time | Approx. 15 min |
| Cold-water flow rate | 1.5 L/min |
| Dynamic pressure | 45 PSI |
The actual cooling time and delivered temperature can vary with ambient temperature, inlet-water temperature, usage frequency, installation conditions, and other operating factors.
3-in-1 Digital Water Tap System
The chiller tank can be upgraded to a sparkling chiller unit; by adding a CO2 cylinder, the system transforms into a 3-in-1 sparkling water tap system.
It provides:
- Filtered Chilled Sparkling Water
- Filtered Chilled Water
- Filtered Boiled Water
UF Filtration Before Drinking-Water Dispensing
The 3 in 1 digital water tap system uses a UF filter as part of the drinking-water treatment system.
The supplied cartridge construction includes:
- Carbon fiber
- UF membrane film
- Internal check valve
- Anti-scale material
- Anti-bacterial material
The check valve is designed to help prevent unwanted water dripping after dispensing.
UF Filter Specifications
| Parameter | Specification |
|---|---|
| Filter media | Carbon fiber + UF film |
| Internal component | Check valve |
| Additional material | Anti-scale and anti-bacterial material |
| Supplied approvals | NSF and WRAS |
| Recommended replacement | Every 12 months or 5,000 L |
| Installation position | Under-counter |
| Application | Drinking-water filtration |
The 12-month or 5,000L replacement interval should be treated as the supplied recommendation and may vary according to incoming water quality and actual consumption.
For private-label projects, filter life should be validated against the final cartridge specification and target-market water conditions.
Digital Touch Control With Preset Water Volumes
The faucet uses a digital interface rather than relying only on conventional mechanical handles.
The supplied configuration includes:
- Touch controls
- Digital temperature display
- Preset water-volume control
- Three-stage water-ration function
- Boiling-water child-safety lock
This makes the faucet easier to operate when users need repeatable quantities of hot, chilled, or filtered water.
For commercial environments such as offices, hotel pantries, hospitality spaces, and kitchen projects, preset dispensing can also make daily operation more consistent.
Child-Safety Lock for 45–98°C Hot Water
Hot-water safety needs to be considered when a faucet can deliver water up to 98°C.
The system includes a child-safety lock for boiling water.
The design also uses a cooling-touch spout to help reduce the surface temperature of the faucet outlet during operation.
For residential and hospitality applications, these features should be evaluated together with the final installation, local safety requirements, and applicable product certifications.
SUS304 + ABS Faucet Construction
The faucet is specified with a combination of SUS304 stainless steel and ABS components.
SUS304 is widely used in kitchen and drinking-water hardware because of its corrosion resistance and suitability for many water-contact applications.
The final material selection should always be checked against the exact water-contact components and destination-market requirements.
The supplied product information states that the materials meet requirements associated with:
NSF / CUPC / WRAS / WaterMark
Certification should be confirmed for the exact finished model and configuration before making market-specific compliance claims.
A Complete Under-Sink Drinking Water System
The 3-in-1 digital faucet is not designed as a standalone tap.
It is part of a complete system consisting of three major under-counter modules:
| System Component | Main Function |
|---|---|
| 3-in-1 digital faucet | User interface and water dispensing |
| 4.0L digital boiler | 45–98°C filtered hot water |
| 2.0L chiller | 3–8°C filtered chilled water |
| UF filter | Drinking-water filtration |
| Digital control system | Temperature and volume management |
This integrated structure allows the visible faucet to remain relatively compact while the larger functional components are installed inside the cabinet.
For kitchen manufacturers and property developers, this can simplify the visual design of the countertop while keeping the drinking-water equipment accessible below the sink.
3 in 1 Digital Water Tap for Kitchen Brands and Private Label
For an international kitchen or appliance brand, the product can be developed as more than a standard catalog faucet.
Potential OEM/ODM development areas include:
- Faucet appearance
- Surface finish
- Branding
- Digital interface
- Packaging
- Boiler configuration
- Chiller configuration
- Filter cartridge specification
- Electrical configuration
- Waterway design
