A receiver tank (also known as a receiver vessel) is a key component in many industrial applications, particularly in systems that involve compressed air, refrigeration, and hydraulics. The primary function of a receiver tank is to store or accumulate fluid, typically in the form of compressed air or gas, and help regulate pressure within a system. These tanks serve as temporary storage devices, providing a buffer to smooth out fluctuations in pressure, optimize system performance, and ensure that the equipment connected to the system operates efficiently and safely.

Receiver tanks are widely used in compressed air systems, HVAC systems, refrigeration cycles, and industrial applications where maintaining a consistent flow of fluid or gas is critical. They help to manage pressure surges, prevent damage to equipment, and improve overall system reliability.
