19L Ultrasonic Cleaning Equipment With Adjustable Frequency Sweeping + Digital Degassing – Eyewear, Jewelry And Watch Cleaning Machine

1. Weather-Resistant Structural Configuration
   Double-layer stainless steel cavity: The inner layer is made of 3mm SUS316L medical-grade stainless steel (resistant to acids and alkalis with a pH range of 1-14). It has passed the 1,500-hour salt spray test (NSS standard) with a corrosion rate of less than 0.015mm per year. The outer layer is a 5mm SUS304 stainless steel frame with built-in sound insulation cotton, and the operating noise is ≤55dB (better than the industry average of 68dB).
   Modular transducer group: Composed of 16 independent PZT-8 piezoelectric ceramic transducer units (energy conversion efficiency ≥95%). When a single unit fails, the system automatically reallocates power, ensuring non-decaying continuous operation for 20,000 hours, with a lifespan more than twice that of traditional equipment.
2. Dual Assurance of Energy Efficiency and Safety
   High-efficiency power supply solution: The IGBT module-driven circuit, combined with PFC power factor correction technology, achieves an energy efficiency ratio of 1.3kW/L (compared to the industry average of 1.0kW/L). It saves 40% more electricity than models of the same capacity, with an annual power consumption of less than 1,200kWh.
   Six-layer safety protection: Degassing overload protection (automatically shuts down when pressure > 15kPa), frequency sweeping over-limit warning (acoustic-optical alarm when frequency deviation > ±0.3kHz), liquid level/temperature interlocked power-off, leakage protection, etc. It has passed all safety certifications of CE, UL, and GB 4706.1-2005.
