1. Does the washing machine need to use pure water throughout?
The washing machine is an automatic device, connected to tap water and pure water at the same time. Generally, it is cleaned with tap water in the front, and pure water is used for the final rinsing, which saves pure water while ensuring the cleaning effect. Both tap water and pure water can be set through the control system, and enter automatically after setting, without manual switching.
2. How long is the cleaning time?
The working process of the washing machine takes about one hour to one and a half hours. Mainly, the washing machine needs a certain temperature of hot water to flush the utensils to ensure the effectiveness and cleaning effect of the cleaning liquid, so the cleaning time is mainly consumed in the heating of the water supply. The washing machine has also added a configuration that shortens the heating time, such as 380V 15KW heating, and the normal work can reduce the washing machine time by about 20 minutes.
3. Does the washing machine have a frequency conversion function?
It has a patent certificate that automatically adjusts the cleaning pressure and can realize the frequency conversion function.
4. Is there any situation that cannot be cleaned?
In the case that the dry-burned, dried-up substances on the utensils and the brush cannot be cleaned, the cleaning machine cannot guarantee the effect, but this type can also be cleaned by combining the immersion and ultrasonic process in the laboratory.
5. Does the washing machine have requirements for the inlet water pressure?
The washing machine has requirements for the water pressure of the tap water, and the water pressure of the normal tap water pipeline is required; for pure water, the water pressure is not
On request, the washing machine has a built-in pure water booster pump, which can independently suck water from the pure water bucket without boosting.
6. What kind of cleaning fluid are you?
We usually recommend the use of RBS cleaning fluid, which is originally imported from Belgium and has a good cleaning effect.
The cleaning solution is usually alkaline washed first, and then neutralized by the acid. Generally, organic or inorganic substances will be decomposed and peeled off under the action of strong alkali to achieve a good cleaning effect.
7. Can the cleaning basket of your washing machine be customized?
The cleaning baskets currently on display basically cover most of the specifications and types of utensils cleaned in conventional laboratories. In general, choosing from the existing cleaning baskets is sufficient for use, and the baskets are also compatible to a certain extent. If it is indeed a special utensil and you also want to clean it, you can customize the basket, but the customization of the basket takes time.
8. Does your washing machine have a plan for instantly judging the cleaning result?
Optional distribution conductivity monitoring system can be used to verify the cleaning effect from the side in real-time.
9. Which model do you recommend?
The recommended model of the washing machine is mainly determined according to the type, specification, and quantity of the utensils required for the test, and the configuration will also be considered according to the requirements of the customer. The conventional 200 and 220 models are the most used, and if the amount of cleaning is relatively small, the 120 configurations can be considered; if the drying requirements are not high or the budget is not high, then the 200S models are more suitable.
10. The customer requires three inlets for hot/cold/pure water. Does the parameter conflict with the customer's requirements?
The machine itself has a heating system, and self-heated water can be added from the pure water port.
