👉 Capacity fluid, also known as flexible or variable capacity fluid, is a type of hydraulic fluid designed to adapt its viscosity based on the operating conditions of a hydraulic system. Unlike traditional fluids with fixed viscosity, capacity fluids can change their thickness in response to temperature variations or pressure changes. This adaptability allows for more efficient operation across a broader range of conditions, reducing energy consumption and wear on system components. By maintaining optimal fluid properties, capacity fluids enhance system performance, extend equipment life, and improve overall reliability.
