In the field of industrial cooling, evaporative coolers have become core equipment in the petrochemical, refrigeration and other industries with their advantages of high efficiency, energy saving, water saving and environmental protection.
However, the harsh working conditions of high temperature, high humidity and strong current impact pose an extreme challenge to the stability of its electronic control system. YMIN capacitors use cutting-edge technology to inject “heart boosters” into evaporative coolers, helping the equipment to achieve zero-fault operation in complex environments.
1. The ultimate solution for harsh working conditions
The evaporative cooler control system needs to work continuously in high temperature (often up to 125°C) and high humidity environments, while withstanding the instantaneous current impact of more than 20A when the water mist spray device is started and stopped. Traditional electricity is prone to overheating and failure due to increased ESR (equivalent series resistance) and insufficient ripple current tolerance, causing system downtime. YMIN capacitors break through with three core technologies:
Ultra-low ESR and ripple current resistance: ESR is as low as 6mΩ or less, and the ripple current tolerance is increased by 50%, which significantly reduces temperature rise and avoids thermal runaway of capacitors.
2000-12000 hours long life design: The lifespan reaches the industry-leading level under 125℃ environment, supporting the equipment to operate maintenance-free for more than 7 years.
High-voltage shock resistance: The capacity of the 450V high-voltage model is up to 1200μF, and the instantaneous current buffering capacity ensures the stable power supply of the water mist spray gun and the fan motor under the start-stop shock.
2. Accurate matching of core module performance upgrade
Water mist spray control system
The spray accuracy of the evaporative cooler directly determines the cooling efficiency. YMIN polymer hybrid capacitor (VHT series) provides instantaneous energy release support for the spray gun solenoid valve, with a capacity of 68μF (35V) and a temperature range of -55~125℃, ensuring zero delay in the start and stop of 4~6MPa high-pressure water mist.
Fan drive and temperature monitoring circuit
Solid-liquid hybrid capacitor provides low ripple DC support for variable frequency fans, suppresses PWM modulation harmonics, and reduces motor jitter; at the same time, it filters and removes noise in the temperature sensor circuit, improves temperature control accuracy to ±1°C, and avoids condensation or over-temperature risks.
3. Create multi-dimensional value for customers
Energy efficiency improvement: capacitor loss is reduced by 30%, helping to reduce the power consumption of the whole machine by 15%.
Maintenance cost optimization: eliminate downtime losses caused by capacitor bulging and leakage, and reduce annual maintenance costs by 40%.
Space saving: miniaturized design adapts to compact controller layout and promotes modular upgrades of evaporative coolers.
Conclusion
YMIN capacitors redefine the reliability standards of evaporative cooler control systems with the golden triangle characteristics of “low ESR, impact resistance, and long life”. From converter dust removal in high-temperature steel mills to cooling towers in data centers, YMIN has escorted the stable operation of evaporative cooling equipment around the world. Choosing YMIN means choosing the dual competitiveness of efficiency and time – let every drop of water evaporate and carry extremely stable energy!
