    Chiller Question, Liquid condenser, Dunham Bush tube cleaning

    Hello all, I have a question on a Dunham Bush liquid cooled condenser chiller. Do I need to remove the refrigerant to rod the tubes on the evap and condenser or not. I've cleaned Yorks and Trane chillers where I did not remove refrigerant. Barrel end caps look the same. Thanks!!

    OK, was wondering why due to the bulkheads behind the end caps that separate the refrigerant from the tubes. Maybe its a safety thing.

    Liquid cooled? Has a tower, or evap condenser? Never pulled a charge to clean a condenser that i can think of. No manual on unit?

    Yes, liquid cooled condenser WCHX-E series. I called Dunham Bush today and they said no you don't have to remove refrigerant to remove the Evap & Cond end caps to rod the chiller. Great for me. Less work!
