Flat Type Ridge Type Operation Principle Chart
The characteristics:
1. Full automatic operation, hot water is provided any time when it is opened;
2. Bearing force 0.6Mpa,6 hot water pressure operation, more comfortable when taking a bath;
3. Adopt heat tube thermal transmission, start quickly,and high thermal efficiency;
4. Inner coating adopts 316L stainless steel.This can reduce intercrystalline corrosion and pit corrosion
5. Vacuum tube will not blast, single piece broken will not effect the application of the whole machine, and the whole machine has a high frost-resistant ability.
