Issue Site

Scaling isn't a cleaning issue—it's an operational cost issue.

Cleaning only affects the result. What truly impacts production are heat exchange efficiency, energy consumption, blowdown rates, and equipment lifespan—all occurring simultaneously.

Self-Check Checklist for Symptoms

01

Frequent cleaning due to scaling

Scaling on heat exchange surfaces requires acid cleaning or high-pressure flushing, which conflicts with the production schedule.

02

Cooling not up to standard

Reduced heat exchange efficiency prevents the medium from reaching the required process temperature, directly impacting production capacity and quality.

03

Chemical and Sewage Load

Complex management of chemical procurement, storage, and dosing; increasingly stringent discharge limits and environmental compliance requirements.

04

Rising energy consumption and maintenance costs

Fouling increases thermal resistance, forcing the system to compensate by boosting flow rates. This drives up maintenance costs for pumps and equipment.

How it works

Where does scale come from, and how does the magnetic field intervene?

The electromagnetic field alters ion arrangement and crystallization behavior in circulating water flowing through pipes, while also affecting biofouling and pipe wall conditions.

Technical Features

Parameters drive results, not slogans.

Five dimensions determine the actual performance of physical methods in industrial circulating water.

01

Wide Frequency

Sweep frequency covers various water qualities, creating resonance with circulating water.

0–6 kHz
02

Strong magnetic field

Larger pipe diameter and more coils result in higher power and greater water processing capacity.

Enhanced with pipe diameter
03

Far away

The magnetic field acts for more than 2 hours, with an effective range of up to 10 km.

2 hours or more
04

Anti-interference

Filter out burrs and clutter; block invalid and counterproductive frequencies.

Remove clutter
05

Stable performance

Power on and run with no maintenance required. Magnetic field remains stable, safe, and long-lasting.

Maintenance-free

Note: Customer names are from publicly available corporate case studies. Actual project results may vary depending on operating conditions and will be determined based on the acceptance criteria agreed upon prior to installation.

Supported Systems

First, determine if this system is usable.

Check three conditions first: pipe diameter, flow rate, and water temperature. Exceeding the range does not mean it cannot be used, but a separate solution confirmation is required.

Products & Selection

One device, covers the entire circulating water system.

A coil is wrapped around the exterior of the pipe, requiring no cutting or system shutdown. The magnetic field acts on the entire system via water flow. This type of equipment is also commonly referred to as an electronic descaler or electromagnetic scale inhibitor.

Applicable Pipe Diameter

Install at branch when main pipe is large.
