For your entire facility, consider a Sola Hevi Duty MCR - a lot of $$ but does the job. Otherwise, enough Furman Voltage Regulators (AR-15 II etc.) to cover all of your circuits. I have survived several electrical events thanks to these (brownouts and lightning strikes). One lightning strike took out the only two things in my studio that did not have a Furman in line. However, 134 V is getting close to the 137 V maximum input of the Furman.
