Crown Castle

Crown Castle: Loop optimization, drycooler retrofit and airflow management

A tenant of 111 8th Avenue’s landmark colocation facility, Crown Castle’s 16,000 square foot data center space faced significant operational inefficiencies. Part of Mantis’ efficiency solutions group, the data center team designed a project including data center loop optimization, BMS and airflow management solutions.

A provider of towers, small cells and fiber, the data center needed better mechanical systems to continue delivering premium service for its own customers. The challenges this energy project tackled included:

  • Supply air short circuiting back to the CRACs
  • Pumps constantly running due to no ability to control loop pressure
  • Continuously running dry coolers
  • CRAC overuse resulting in wasted energy and cost
