Hello all. About 10 months ago you folks were very helpful, advising about maintenance issues and an upcoming modernization project. Time to take advantage of your expertise again.
We have 4 bids in from (obviously) 4 companies. Two are Otis and Kone. Two are smaller local non-prop companies. O
Bids are complicated (at least for me) but let's just focus on the controllers, since that seems to be where most of the action is.
Non-Prop 1: Elevator Controls Inc. Controller; this is a DC (but regenerating?) controller which will allow us to keep our '60s-vintage DC motors (good or bad?)
Non-Prop 2: GAL Galaxy AC (model not specified)
Otis: Elevonic with ReGen VF Drive
Kone: Kone ReSolve System
Thoughts?
Thanks!
