Can you have single phase immersion in a retrofit or existing data center with other cooling architectures? Any data center designed with water loops for heat rejection can support single-phase immersion cooling—it's that simple. In fact, single-phase immersion often makes more efficient use of those existing loops, allowing for higher IT density. You can typically run more kilowatts of equipment than you could with traditional cooling methods. -- Rusty Cone General Manager, VP Business Development, UNICOM Engineering Can you have multiple cooling architectures in one data center? It is rare to find any liquid cooling facility that only has one cooling technology deployed. They are almost always a hybrid of air and/or multiple liquid coolant technologies. It may, however, require management of different primary loop requirements. -- Christopher Liljenstolpe, Sr. Director, Data Center Architecture & Sustainability, Cisco
How efficient is heat recovery for single phase immersion? Single phase immersion cooling allows for higher inlet and exit water temperatures. In facilities with a water loops, exit temperatures often exceed 50 ° C, qualifying as high- quality heat suitable for reuse in building heating, swimming pools, and farming, where 50-60 ° C is the target range. Other technologies max out around 40-50 ° C making heat reuse harder and less effective. -- Austin Hipes, VP, Engineering, UNICOM Engineering What is the impact to PUE? We have seen a long term customer from the banking sector with Tier4 data centers reporting an estimated impact on PUE from 1.4 to 1.04 all year, meeting their ESG requirements. -- Maikel Bouricius Chief Growth Officer - Asperitas
