We use a high-performance vacuum pump for vacuuming, achieving a vacuum level that is just 1 millionth of daily air pressure, essentially reaching a complete vacuum state. In this condition, all water, contaminants, and oil inside the refrigeration system are removed to ensure the quality of our products. The next step is refrigerant injection, with the control precision of the infusion maintained at ±0.5 grams, which is equivalent to the weight of a small capsule.
