👉 The outlet fluid, also known as oil or coolant oil in some systems, is a specialized lubricant and coolant mixture that plays a crucial role in the proper functioning of various mechanical components, particularly in hydraulic and heat exchanger systems. It is typically circulated through the system to reduce friction between moving parts, dissipate heat away from critical components, and prevent wear and tear. The fluid's composition is carefully formulated to maintain optimal operating temperatures and ensure efficient performance while also providing protection against corrosion and contamination. In hydraulic systems, it helps transfer power from the pump to the actuators, while in heat exchangers, it aids in transferring heat away from the heat source to the cooling medium.
