When the factory is approved, we begin prototyping.


We discuss essential points such as appearance, critical dimensions, critical regions, and performance with the manufacturer.


We evaluate the sample, ensure that the process/material is the same as expected in mass production, and then provide you the sample together with a thorough report.



Mass Production


Before beginning production, we repeat the evaluation process with the manuafactuer, emphasizing and ensuring that improvements identified.


When everything is settled well, the mass production will be started.





During production, we do in-process inspections like:
Raw Material Acquisition
Process Low Lead-Times
Process Stages/Steps


We do extra works  once manufacturing finish such as:
Packaging/Secure Transit
Critical Dimensions/Specifications
Shipping Marks

Mainstream 3 types

  1. Freestanding bottleless water cooler: The general commercial bottleless water cooler is mainly vertical, with a water tank inside the device, which occupies a large area.
  1. Counter top bottleless water cooler: The countertop type is suitable for families who are not convenient to directly connect to the water purification system. They need to constantly add water to the water tank by themselves. The advantage is that they can move freely.
  1. Wall-mounted bottleless water cooler: The wall-mounted bottleless water cooler can be connected to the home water purification system. The bottleless water cooler is directly hung on the wall and does not occupy the space in the house.

There are two main sources: wastewater rinse and wastewater filter.

  1. Wastewater rinse:
    RO-membrane is flushed by the wastewater. The filtrated wastewater is a section of retentate produced during the filtering of tap water that is blocked by the RO membrane when the machine restarts to generate water that prevents the RO membrane from becoming blocked and extends the life of the RO membrane.

2. Wastewater filter:
According to the pure water recovery rate of about 30% set by general manufacturers, daily consumption of 4GL pure water (basically enough for drinking and cooking) will produce 9.2GL wastewater, and the total water consumption is 13GL, and the total wastewater is 1.05T in 30 days per month. Tons (9.2GL*30=276GL=0.37Ccf), based on the current Washinton water price of Residential – 0 – 4 Ccf $3.49, the wastewater produced in a month is only $1.29.
