Under Sink Chilled Water Dispenser
An under sink chilled water dispenser provides chilled drinking water directly from a dedicated tap while keeping the cooling unit hidden inside the cabinet. Xiamen Smart Water Technology Co., Ltd. manufactures compact under-sink water chillers for drinking-water brands, kitchen manufacturers, distributors, and private-label buyers. The system uses compressor cooling, a 2.4-liter stainless steel cooling tank, and an adjustable temperature range of 2–12°C, with a rated chilled-water output of up to 8 liters per hour.
For kitchens, offices, hotels, and other commercial spaces, this setup reduces the need to refill water pitchers or store bottles in a refrigerator. The chiller connects to the water supply and can be paired with a compatible inline filtration system when filtered drinking water is required. Its under-counter installation keeps the countertop clear while providing convenient access to cold water throughout the day.

How Does an Under-Counter Water Chiller Work?
An under-sink water chiller connects to the water supply and cools incoming water using a compressor-based refrigeration system. Chilled water is stored in the cooling tank and delivered through a compatible drinking-water faucet when needed.
The basic operating process is straightforward:
- Water enters the system: The chiller receives water through its inlet connection.
- The refrigeration system cools the water: The compressor-based cooling circuit removes heat from the water.
- Chilled water is held in the tank: The 2.4L tank provides a ready supply for dispensing.
- Water flows through the tap: When the user opens the compatible drinking-water outlet, chilled water is delivered without needing to refill a pitcher.
The 2–12°C temperature range lets buyers assess the unit for different cold-water preferences and operating requirements. The selected temperature, ambient conditions, and frequency of dispensing will affect the system's cooling workload.
Key Features of This Under Sink Chilled Water Dispenser
1. Hidden installation keeps the countertop clear
The cooling unit sits inside the cabinet beneath the sink, leaving the visible drinking-water area uncluttered. This layout is useful for kitchens where counter space is limited or where a clean, integrated appearance is part of the design.
For kitchen manufacturers and plumbing brands, the under-counter format also allows the chiller to be combined with a suitable drinking-water faucet rather than using a separate countertop appliance.
Before specifying the unit, check cabinet dimensions, ventilation requirements, power access, plumbing connections, and service clearance.
2. Compressor cooling with a 2–12°C setting range
The chiller uses compressor cooling rather than relying only on ice or passive cooling. Its specified temperature range is 2–12°C, giving users a way to select the desired chilled-water temperature within the model's operating limits.
The actual dispensing temperature may vary with incoming water temperature, room conditions, dispensing frequency, and the time allowed for the unit to cool the water. Buyers supplying the product for warm climates or high-use commercial environments should request performance data under representative operating conditions.
3. Rated output of up to 8 liters per hour
The unit is specified to produce up to 8 liters of chilled water per hour. This rating helps buyers compare cooling capacity when planning a drinking-water system for a home, office, hospitality setting, or other installation.
The 2.4L tank provides stored chilled water, while the hourly output indicates the stated cooling production capacity. These figures describe different aspects of performance: tank capacity is not the same as hourly production.
For projects with repeated or simultaneous demand, assess both figures alongside peak usage, inlet-water temperature, and cooling recovery time.
4. 304 stainless steel cooling tank
The cooling tank is specified as 304 food-grade stainless steel. This material is widely used in water-contact applications because of its corrosion resistance and suitability for many drinking-water system designs.
Material grade alone does not establish complete system compliance. For commercial projects, buyers should also review the materials used in tubing, seals, fittings, and other water-contact components, together with any applicable test reports or drinking-water approvals.
5. Low-noise operation
The supplied specification lists a noise level of less than 40dB. This can be relevant for residential kitchens, hotel rooms, office pantries, and other locations where background noise matters.
Because measured noise depends on operating conditions, installation, distance, and the measurement method, buyers should confirm the manufacturer's test conditions before using this figure as a direct comparison with competing units.
6. R290 refrigerant
R290 offers high refrigeration efficiency and meets the latest EU standards.
Under Sink Chilled Water Dispenser with an Optional Water Filter
The chiller can be paired with a compatible inline water filtration system when the application requires treated drinking water. This allows the cooling unit and filtration stage to be specified according to the incoming water quality and the desired treatment performance.
Filtration and cooling perform different jobs:
| System component | Main function | What buyers should confirm |
|---|---|---|
| Under-sink water chiller | Lowers water temperature | Temperature range, tank capacity, hourly output, and recovery |
| Inline carbon filter | Can reduce specified tastes, odors, or contaminants | Media type, rated capacity, and validated contaminant-reduction claims |
| Ultrafiltration (UF) system | Can reduce particles and certain microorganisms, depending on membrane design | Pore rating, tested performance, and operating conditions |
| Reverse osmosis (RO) system | Can reduce dissolved substances and other specified contaminants | Rejection performance, water pressure, wastewater arrangements, and compatibility |
| Drinking-water faucet | Delivers chilled water to the user | Connection size, flow rate, material suitability, and tap compatibility |
A filter is not automatically included with the chiller. The filtration unit, fittings, and faucet should be selected to match the installation and the intended water treatment requirements.
For buyers serving markets with specific drinking-water regulations, confirm the performance claims and approvals for the complete configuration rather than relying on the filter type alone.
What Is Included in the Package?
| Package item | Quantity |
|---|---|
| Under-sink water chiller unit | 1 |
| Mains water connection kit | 1 |
| Power cable | 1 |
| Installation guide | 1 |
A compatible drinking-water faucet and inline filtration system should be confirmed separately unless they are explicitly included in the final quotation. Buyers should also verify the required inlet fittings, outlet connections, power plug, and installation accessories for their market.
Installation Requirements for an Under-Sink Water Chiller
The chiller is designed for cabinet installation beneath the sink. Before ordering, confirm that the planned installation has enough room for the unit, its ventilation requirements, water connections, power cable, and future maintenance.
| Installation item | What to check |
|---|---|
| Cabinet space | Confirm the unit's actual dimensions and allow room for servicing |
| Ventilation | Follow the manufacturer's clearance and airflow instructions |
| Electrical supply | Match the specified voltage, frequency, plug, and circuit requirements |
| Water inlet | Confirm fitting size, water pressure, and connection compatibility |
| Faucet outlet | Check the required tubing and faucet connections |
| Filter integration | Confirm the sequence and compatibility of the filter and chiller |
The actual product dimensions and permitted installation clearances were not included in the supplied specifications. These should be confirmed before cabinet design or bulk procurement.
Applications for Under Sink Chilled Water Dispensers
The compact under-counter design and direct water connection make this type of chiller suitable for a range of drinking-water applications.
- Residential kitchens: Provides chilled drinking water without taking up countertop space.
- Offices and workplace pantries: Offers a dedicated chilled-water source for employees and visitors.
- Hotels and hospitality facilities: Can be incorporated into suitable guest or staff drinking-water areas.
- Restaurants and food-service spaces: Provides chilled water where the rated capacity matches expected demand.
