This component is used in the following industrial products
The hydraulic reservoir is a critical component of a hydraulic press that stores hydraulic fluid, allows for thermal expansion and contraction, facilitates air separation and contaminant settling, and provides a reserve of fluid to compensate for leaks and system demands.
A container that stores and supplies coolant fluid within a water cooling system.
The coolant tank or reservoir is a critical component of coolant systems that serves as a storage and supply vessel for coolant fluid.
