When sourcing a 15kg industrial washing machine, you must prioritize the G-Force (Extraction Speed), which should ideally be between 300G and 400G to minimize drying time and energy costs. Ensure the inner drum and outer panels are made of SUS304 Stainless Steel to prevent corrosion from industrial chemicals. Additionally, verify the Inverter Drive System quality, as it controls motor stability and reduces peak power consumption, and check if the machine features a Suspension Vibration-Damping System to allow for high-speed extraction without the need for specialized floor foundations.
