Hydraulic Filler Units

Hydraulic Filler Units
1. A large surface area to transfer heat from the fluid to the surrounding environment
2. Enough volume to let returning fluid slow down from a high entrance velocity. This lets heavier contaminants settle and entrained air escape
3. A physical barrier (baffle) that separates fluid entering the reservoir from fluid entering the pump suction line
4. Air space above the fluid to accept air that bubbles out of the fluid
5. Access to remove used fluid and contaminants from the system and to add new fluid
6. Space for hot-fluid expansion, gravity drain-back from a system during shutdown, and storage of large volumes needed intermittently during peak periods of an operating cycle,
