datacenters.lbl.govSep 15, 2020 · In the past, increasing space humidity was often used to prevent ESD failures . However, industry practices have changed partly because IT equipment has become more resistant to ESD failures. The recommended procedure is now thorough grounding of equipment, cables, flooring, and personal (wrist straps). Telecom

It is also possible to achieve higher entering-to-leaving chiller differentials, which may, in turn, provide the opportunity for lower chilled water design temperature, lower design flow, and resulting installation and operational cost savings (including downsizing a chiller).
