Products & Technology

DeWeiHan is a German-engineered, imported variable-frequency resonant water treatment system designed to prevent scale formation, remove existing scale, kill bacteria and algae, and inhibit corrosion in industrial circulating cooling water systems.

Apply a frequency-sweeping electromagnetic field of 0–60 kHz to circulating water to alter the crystallization and adhesion behavior of scaling ions.

0–6 0KHz frequency sweep to cover different water qualities and operating conditions.

Composed of self-inductive coils and mutually inductive capacitive coils, both magnetic fields act simultaneously on the circulating water.

The fifth-generation variable-frequency resonant electromagnetic field technology integrates the experience of the previous four generations of physical water treatment.

Yes. The equipment is imported directly from Germany, and Shandong Zhengyi International Trade Co., Ltd. serves as the exclusive distributor for the China region.

Certified by international research institutions for the efficacy of physical descaling technology, with recognition and qualifications from relevant German government ministries.

The Green Technology Promotion Catalog, issued by the National Development and Reform Commission and three other ministries, includes variable frequency resonance water treatment as a promoted technology.

Designed for long service life: the host has no mechanical wear parts and can operate reliably for extended periods.

Model selection is based on flow rate and pipe diameter; refer to the final configuration plan for specifics.

Wide frequency range, long operating distance, and strong interference resistance. Can replace chemical treatments in most scenarios; specific evaluation required based on water quality and microbial/algal corrosion conditions.

0–6 kHz frequency sweep with dual-coil capacitor-inductor structure, generating an alternating electromagnetic field that covers the entire system.
