Compact Rack Mounted Air Filtration System

When information technology (IT) equipment becomes contaminated with sulfur-bearing gases, the datacenter environment must be cleaned with chemical based filters to remove the sulfur and other gaseous contaminants from the environment. Typically, these chemical filters are installed on the top of the computer room air-conditioning (CRAC) units, replacing the existing particulate filter. However, this increases the pressure drop of the CRAC system, which can affect the cooling performance of the

CRAC and increase the stress on the CRAC blowers.

Alternatively, standalone systems can be installed in the room; however, these units occupy floor space and need to be judiciously distributed throughout the data center to be effective.

The American Society of Heating, Refrigerating and Air Conditioning Engineers Technical Committee (ASHRAE TC) 9.9 standards specify that the server inlet is the correct place to maintain the recommended environmental parameters related to temperature, humidity, and corrosion rate. ASHRAE specifies that the recommended

corrosion rates maintained in the datacenter are a Copper reactivity rate of less than 300 A/month and a silver reactivity rate of less than 200 A/month.

The challenge is to filter out the gaseous contamination in the air entering the racks

with the least amount of disturbance to the data center infrastructure.
