1. The interior of YATE assistant tanks use SUS304-2B stainless steels, automatic two-sided protection, TIG welding, automatic girth butt welding, automatic welding pipe fitting, which will not damage the stainless steels, and no intergranular corrosion to keep the water clean.

2. YATE assistant tanks' shells and other things use imported paint galvanized steels with corrosion-resistant. The connections will not jump off or corrosion and will have long lives.

3. Insulations use imported automatic polyurethane foam equipment foam wholly. The foam craft is strict and foam layer has a high-density which is non-empty, even holes, dense, heat-insulating property well and can be used for a long time.

4. Seals and other things are made of high-quality silicone rubber material. And they can be no deformation, non-toxic, anti-aging after immersing in hot water for a long time. The particular multi-channel leak-proof design ensures that it will not leak after installing.

5. Spool valve is made of special flexible materials, which is no scale, no distortion, no wear. The procedure which adjust the spool valve closed automatically is reliable.

6. Valve pocket is made of high polymer materials which is self-lubricating well, wear-resistant and non-fouling.

7. Float is made of SUS304-2B stainless steels which passes the test of leakage-proof in high pressure and can be used for a long time.
