What is a barrelless machine?
There is no unified statement in the water purification industry for what is a barrelless machine. Generally speaking, a reverse osmosis (RO) water purifier without a pressure tank (water storage container) and a RO membrane flux of 400 gallons (purified water production of 1 liter/min).
Why is the reverse osmosis (RO) water purifier equipped with a pressure tank?
At present, the mainstream reverse osmosis water purifier on the market is 75 gallons, 75 gallons is equivalent to 197 ml of water per minute. The bottled water we usually drink is 550 ml, and it takes about 2 minutes and 47 seconds to receive a bottle of water.
The water purifier is installed at home for drinking water and cooking. The water production rate of 197 ml/min is too slow, but in actual use, it is not without water. Therefore, this water purifier should be equipped with a pressure tank to store the clean water when we do not use water. When we need to pick up water for cooking and drinking, we can quickly release the water.
To put it bluntly, it is to use the buffer water of the pressure tank to solve the problem of slow water production.
Why don't you use a pressure tank without a barrel machine?
Let's see how the business is advertised.
1. The pressure tank is a source of pollution, no barrel is fresher, that is, ready to drink;
2, small size, saving installation space;
3. Large amount of water;
. . . . . .
It looks very good, what is the actual situation?
Laojiao began to engage in clean water in 2009. In the eyes of Laojiao, the barrelless machine is always a product that looks beautiful. Before 2010, the barrelless machine did fire, but it was silent for the next few years. In recent years, no barrel machine has started to scam.
The swindlers were deceived, but there were three major injuries in the barrel machine that could not be solved.
Pressure bucket
No barrel machine three major injuries
1. Poor customer experience
At present, there is no barrel machine with 400 gallons as the mainstream. The water production speed of the 400-gallon RO membrane is 1 liter of water per minute under standard conditions (water temperature 25 ° C, TDS 250 ppm). Considering that few customers' water quality meets the standard conditions, especially the northern water temperature can only reach 25 °C in summer, the water hardness is high, and the TDS is generally higher than 250 ppm. The actual water production speed of this barrelless machine is less than 0.8 liters/ minute.
Our household electric kettle has a capacity of about 1.5 liters, and it takes about two minutes to pick up a pot of water. Imagine if the family came to the guests, we took the water in the kitchen and left the guests there for two minutes. How awkward! This is not a big deal. If you have a porridge? We need more water and it takes longer to pick up the water. .
It’s so hard to pick up a water, how can consumers be satisfied with it?
2, a small amount of water is not good
Reverse osmosis (RO) water purifiers have a general characteristic. Whenever water is started, the resulting TDS is particularly high, and it takes a while for the TDS to be lowered. There is no pressure tank to buffer water in the barrelless machine. Every time it is made, it has to go through the process of high water to low TDS. The water-free speed of the barrel-free mechanism, we take a cup of water (about 200 ml), the cup is full, and the TDS has not yet come down. High TDS means that the water quality is very bad!
3, high cost of use
The cycle change cycle of the barrelless machine is similar to that of the ordinary 75-gallon machine. Although the price of the first three-stage filter is similar, the price of a 400-gallon RO film is several times that of a 75-gallon RO film! Spend a few times the money!
In summary, the water release rate is slow, the water is not good to drink, the core replacement is expensive, and the use experience is a few streets with a barrel machine. Laojiao can't see what is good with the barrelless machine! What do you think?
