Fluid system components

Chilled water supply and return header pressure sensors

The HP POD 20c contains two chilled water pressure sensors. One is located in the chilled water supply header and one is located in the return header.

The chilled water supply and return header pressure sensors are located in the cold aisle where the headers penetrate the HP POD 20c.
