Happy Minor Heat, Peaceful Cool Summer | With pure water technology, we safeguard the crystal beauty of midsummer
Warm breezes creep in unawares,
And Minor Heat arrives in due course.
Minor Heat marks the prelude of midsummer. The heat grows stronger, rainfall turns abundant, and all living things thrive in their prime growth.
Ancient records state: "The early lunar phase brings Minor Heat, when the warmth is mild yet budding." Unlike the scorching extreme of Major Heat, Minor Heat carries lingering mild warmth and rising dampness.
The ancients divided Minor Heat into three pentads: warm winds arrive; crickets move indoors; eagles begin to hunt fiercely.
Warm gusts brush the cheeks, cicadas chirp nonstop, and all nature flourishes—painting a vivid, lively scene unique to midsummer.

The Minor Heat period brings high temperatures, heavy humidity and frequent rainfall. While water bodies circulate vigorously, algae tend to multiply rapidly and impurities accumulate easily, leading to turbid water and accelerated wear of water equipment. Natural water areas, as well as civil and industrial water supply systems, all face severe challenges in water purification and maintenance.
In the sweltering midsummer, clean water is the foundation of vitality. A stable and pure water environment serves as a vital guarantee for comfortable daily life and steady industrial production.
