What are the classifications of energy-saving direct RO purification heating water dispensers?

Straight drinking machine: It is the general name of pure water machine (RO filtration) and ultrafiltration water purifier. It belongs to filtration equipment. The water processed by the straight drinking machine can be safely drunk directly, so it is called a straight drinking machine.
Pure water machine: Pure water comes out of the pure water machine. Its reverse osmosis membrane has a filtration aperture of 0.1 nanometers, so pure water has no impurities at all. After boiling, there is no scale and no minerals. The filtering air diameter of the filter type water purifier is 0.02 microns. Compared with the pure water purifier, the ultrafiltration water purifier belongs to coarse filtration, and there is scale after boiling. minerals.

Pipeline machine: The pipeline machine is also known as the pipeline water dispenser. The pipeline machine is directly connected to the direct drinking water source, such as RO reverse osmosis purified water or UF ultrafiltration membrane purified water, so the pipeline machine is usually installed and used with a water purifier.
The pipeline machine can quickly provide hot water through the electric heating module, and the pipeline machine that can provide the function of ice water is called the cold and hot pipeline machine. The rapid heating function of the pipeline machine is usually to meet the drinking water needs of the home and office environment. The pipeline machine does not have the function of filtering and purifying water.
The difference and relationship between the three:
Strictly speaking, the pipeline machine can only heat or make ice from the water provided by the upstream pure water machine or ultrafiltration water purifier. However, some pipeline machines do not have upstream water purification equipment, but have their own filtering function. Ultra filter element, this kind of pipeline machine is actually similar to the straight drinking machine, which can be regarded as a kind of straight drinking machine that can provide cold and hot water.
If the pipeline machine itself has the water purification function of RO reverse osmosis membrane, without the need of the upstream water purifier, and directly connected to the tap water source, the pipeline machine can be regarded as a kind of pure water machine that can provide cold and hot water.
After some consumers install a pipeline water dispenser without water purification function, they are directly connected to tap water. In this case, the pipeline water dispenser is similar to the traditional bottled water dispenser.
