Pressurisation Solutions
Weatherite’s fully packaged, self-contained pressurisation / RH control solutions are designed and built to meet the demanding requirements of data centre environments, preventing contaminants entering the data halls and avoiding damage to the servers and the valuable data they hold.
Weatherite’s “PressureTec” units condition the outside air so that it can be supplied in to either the cold or hot aisle or directly into the data hall if aisle containment is not deployed.
“PressureTec” is a packaged solution, so everything required to provide precise conditioned air is contained within a single unit; no need for remote condensing or humidification units installed elsewhere within the hall. The PressureTec unit just requires an electrical connection, water supply, for the humidifier, drainage and BMS connection for monitoring and alarms. The electrical supply could be via a changeover, providing diverse A & B supplies, backed-up by generators or UPS.
Designed for external environments, our twin wall, fully weather proofed construction ensures the PressureTec units are built for long life with minimal maintenance -protecting the internal components from varying external weather conditions.
What is a Data Centre pressurisation solution
Data centres require positive pressurisation aimed at preventing contaminants entering the data halls and ultimately the servers.
The supplied air is taken from the surrounding outside environment and differs depending on local conditions. Local environments can range from coastal, suffering from airborne sea salt, to industrial or commercial sites with contaminants that could be harmful if they were to reach the data centre servers. The local conditions can also vary from extremely cold and dry winter conditions to very warm and humid summer conditions.
‘Pressurisation solutions’ regulate the amount of ‘conditioned’ outside air supplied into the data hall, in order to ensure the room is kept at positive pressure and supplied within the specified range of temperature and relative humidity.
