While incredibly powerful, the system is remarkably compact. The size of a 14-inch laptop, it discreetly fits inside most kitchen cabinets. The water cooler uses a compressor-based cooling system that efficiently chills water, The water cooler uses a compressor-based cooling system that efficiently chills water, delivering up to 8 liters of cold water per hour. It takes barely 20 minutes to reach the optimal temperature from room temperature. Manufactured using SS304 food-grade stainless steel, the system’s water components are safe, durable, and reliable.
For additional water purification, pair the unit with an optional inline filtration system. This addition makes it an ideal solution for cafes, serviced apartments, small offices, and modern kitchens seeking high-quality, safe, and refreshing drinking water on demand.
How the 3-in-1 Undersink Water Cooler Works
Let’s walk you through the operational procedure for the 3-in-1 undersink water cooler.
Cold Water:
If you get our cold water system, you can enjoy a consistent stream of refreshing chilled water. It produces cold water using a built-in compressor, similar to a household refrigerator. Water from the main line moves through the cooling coil and is chilled to 5° to 10°C. The unit delivers up to 8 liters of cold water/hour. It takes about 20 minutes to reach the target temperature from the point you start it.
Hot Water:
If you want a nonstop supply of hot water, get our hot water system. It features a built-in hot water tank that dispenses near-boiling (93°C) water on demand. Retire your kettle and get instant meals, baby formula, tea, and coffee with a quick turn of the tap. Routine kitchen tasks become quicker and easier.
Ambient/Room-Temperature Water:
The system also delivers room-temperature, ready-to-drink water directly, without requiring additional cooling or heating. This is an ideal option for children and those who prefer non-chilled water.
Filtration (If Installed):
If you combine the undersink water cooler with an inline filtration system, incoming water passes through an additional filtration stage using a reverse osmosis (RO) membrane, an activated carbon block, or an ultrafiltration (UF) membrane. Filtration removes chlorine, sediment, heavy metals, hardness minerals, total dissolved solids, and other contaminants from the water. As a result, you get better-tasting, cleaner, and safer drinking water.

The compressor uses the same refrigerant (R134a or R600a) that many advanced refrigerators use to cool. You get reliable cooling with a lower environmental impact.
5-Year Warranty:
Every illi water system, including the 'Under-Sink Water Cooler,' comes with a 5-year manufacturer's warranty, giving you confidence that your system will perform optimally for many years to come.
Compressor Cooling: Why It Matters
Powered by genuine compressor refrigeration, identical to the technology found in modern refrigerators, the Illi Water under-sink water cooler delivers dependable, efficient performance.
Not all water coolers utilize advanced technology. Basic water dispensers rely on thermoelectric (Peltier) cooling systems. It is slower and often struggles to maintain consistently cold temperatures in warmer environments.
The illi water under-sink water cooler takes a different and more cutting-edge approach. Using the true compression refrigeration technology, the system’s compression chills water from room temperature to as low as 5°C in only 20 minutes. Plus, it delivers a steady stream of 8 liters of cold water per hour. So whether it’s a dinner rush, busy morning, or unexpected guests to serve, cold water is always available.
The system also performs reliably in warmer kitchens, where thermoelectric units often lose efficiency. Water is stored in an SS304 stainless steel cold tank for hygiene and durability, while R134a or R600a refrigerant ensures efficient, environmentally responsible cooling.
