Liqui-Chill built very efficient chiller for us; both in air conditioning and in making ice for Thermal Energy Storage; used German open shaft compressors, Bitzer. These are the kind make you want to repeat the champagne glass on the running engine - that is how smooth they run. We received more than one hundred thousand dollars in NYS efficiency grants just due to the chiller. GC gave us one day to start this up; Vance got us going and it chilled down the new building 65,000 square feet over weekend and fine tuned it to run flawlessly.
