What are the advantages of Dewei Han compared to other medications?
More stable performance, lower operating costs, no water quality changes, and no need for chemical dosing or management.
Dewehan vs. Softened Water: How to Choose?
Use softened water for low flow and low evaporation; opt for physical treatment when flow is high and cost is a priority, as it preserves water quality.
What is the difference with a permanent magnet descaler?
Permanent magnets rely on fixed magnetization and are prone to demagnetization; variable-frequency resonance generates a stable, continuous alternating magnetic field for more consistent performance.
What's the difference with high-voltage electrostatic water treatment?
High-voltage electrostatic action has a short effective range and causes insulation aging; variable-frequency resonance covers the entire circulation system.
What is the difference from electrolytic water treatment?
Electrolysis relies on electrode reactions, causing anode wear; variable-frequency resonance involves no electrode consumption and handles larger water volumes.
How does it compare to ultrasonic descaling?
Ultrasonic systems are typically used for localized or single-unit applications, while frequency-resonance systems cover the entire network via circulating water.
Are electronic descaling systems and frequency resonance the same thing?
No. Most electronic descalers on the market use a single frequency or simple pulses, while Dewihan employs 0–60KHz sweep frequency with a dual-coil structure combining capacitors and inductors.
Can physical treatment replace chemical cleaning?
Can replace routine chemical cleaning, though initial commissioning or heavily scaled systems may still require a one-time cleaning to start.
Is acid dosing effective for scaling control?
Adding acid reduces alkalinity but poses corrosion risks, requires strict safety protocols, and is difficult to control reliably.
Can side filtration replace descaling?
No. Side filtration removes suspended solids but has limited effect on hard scale already adhered to the heat exchange surface.
What is the difference between scale inhibitors and physical scale prevention?
Anti-scalants alter crystal morphology through chemical action, while physical methods use electromagnetic fields to influence ion and molecular cluster behavior.
Can disinfectants be discontinued entirely?
Most recirculating water systems can reduce biocide usage, but open systems and hot seasons still require essential microbial control.
Are there specific operating conditions that haven't been covered yet?
Provide parameters for a written assessment by the technical team.
