What is the Active Flow Control of an EcoAisle System and what Cooling System are compatible.

Issue:
This document will describe and explain what is the Active Flow Control of an EcoAisle System and what Cooling System are compatible.

Product line: EcoAisle

Environment:
Only ACRC100, EcoBreeze, ACRC301S, ACRC301H, ACRC500

Cause:
Install

Resolution:

• Active Flow Control

- The active flow controller was designed for various mounting methods in the door header, in a duct or mounted in a U space of the rack.

- The active flow controller monitors the airflow balance between the cooling system and the IT equipment. It senses the airflow in the contained aisle and sends a control signal to the cooling equipment to vary the fan speed to match the airflow that the server is producing.

- The controller has 3 LED rings that will change colors based on differing airflows. If the cooling unit is providing excess airflow the light color will change to blue. If the cooling unit is not providing enough airflow the light color will change to red. If the cooling unit is providing the right amount of airflow the light color will change to Green.

- This option is only available with the ACRC100 series as well as the EcoBreeze unit at the time of release. The other products will have the firmware modified to allow compatibility at a future date.
