As a professional developer and manufacturer of evaporative air cooler PCB control boards, we focus on providing one-stop PCB solutions—from scheme design to mass production delivery—for household, commercial, and industrial evaporative cooling equipment. We have development capability across both AC-driven and DC brushless variable-frequency-driven technology routes, and can customize core control logic such as fan speed adjustment, water pump management, oscillation control, and temperature/humidity sensing based on the cooler's power rating, control method (button/remote/touch/smart app), and protection rating requirements. All products use high-quality substrates and components and pass rigorous aging and EMC testing to ensure long-term stable operation under humid, high-load conditions. Drawing on years of PCB design and SMT mass-production experience, we provide OEM/ODM one-stop services to air cooler manufacturers and brands worldwide, flexibly supporting everything from schematic design and sample verification to bulk delivery — helping customers speed up new-product launch cycles and lower overall R&D costs.
