High Voltage Doorknob Capacitor 20kV-2000pF Efficiency Multiplier for Electrostatic Dust Removal and Spraying/Coating

Efficiency Multiplier: Dedicated Capacitor Solutions for Electrostatic Precipitators and Electrostatic Spraying
Although electrostatic precipitators and electrostatic spraying have different applications, their core technologies both rely on efficient and stable high-voltage electrostatic fields. As a key component in high-voltage power supplies, capacitor performance directly impacts both process results and operating costs. We deeply understand the unique needs of these two industries and provide precisely optimized capacitor solutions.

Electrostatic Precipitator Applications: Safeguarding Clean Energy and Green Production
In power plants, cement plants, steel mills, and other applications, the efficiency of electrostatic precipitators is crucial for meeting environmental emission standards.

Industry Pain Points:

Harsh Operating Conditions: High temperatures, high dust levels, and the potential for corrosive gases such as sulfides.

Extremely High Voltage: Operating voltages typically range from 40kV to over 100kV.

Continuous Operation: Requires extremely high reliability, and unplanned downtime is costly.

Our Exclusive Solutions:

High Reliability and Long Life Design: To address these harsh operating conditions, we enhance the hermeticity and corrosion resistance of the packaging. The capacitor's design life matches the dust collector overhaul cycle, significantly reducing lifecycle maintenance costs.

Excellent shock resistance: Frequent spark discharges within dust collectors can cause transient voltage surges. Our capacitors, with their superior voltage headroom and self-healing properties, effectively absorb these energy surges and protect the power supply's main circuits.

High-voltage product line: We offer a complete product line with rated voltages up to 100kV and above, suitable for direct use in high-voltage filtering and voltage multiplication circuits, simplifying your power supply design.

Electrostatic spraying/coating applications: Bringing superior surface finish quality. In industries such as automotive, furniture, and consumer electronics, electrostatic spraying achieves uniform, highly adherent coatings, saving on paint.

Industry Pain Points:

Extremely high voltage stability requirements: Voltage fluctuations directly impact adsorption efficiency and coating uniformity.

Demanding precision: Smooth, low-ripple DC high voltage is required to achieve a flawless surface.

High equipment integration: Equipment such as spray painting robots requires capacitors that are compact and lightweight.

Our proprietary solution:

Extremely stable capacitance: Utilizing temperature-compensated ceramic dielectrics ensures minimal capacitance variation over a wide temperature range, providing extremely stable filtering and guaranteeing output voltage purity.

Low inductance and high-frequency characteristics: Optimized structural design reduces parasitic inductance, effectively filtering out high-frequency ripple generated by modern switching power supplies and meeting the stringent power quality requirements of precision spraying.

Compact, high-energy-density design: While meeting withstand voltage requirements, we leverage advanced material technology to achieve a smaller footprint, enabling higher integration and flexibility in spraying equipment.
