During a system upgrade to the 1901 Brunswick Office Building, CSG worked in conjunction with a local mechanical contractor to change out the structure’s cooling system. The contractor removed a single 120 ton DX cooling system and replaced it with a chilled water system. The only work allowed before the change-out was the installation of the chiller and piping to the roof. The main change-out took place over one weekend. CSG installed the complete control system for this project in just over twenty four hours and by Monday morning the system was under control and working perfectly.
