High efficiency water cooled chiller

Indoor unit for the production of chilled water featuring centrifugal oli-free compressors, with refrigerant HFO 1234-ze, electronic regulation valve, shell and tube condenser and shell and tube flooded evaporator. Base and supporting structure and panels are made of galvanized epoxy powder coated steel with increased thickness. Flexible and reliable unit it easily adapts itself to different thermal load conditions thanks to the precise thermoregulation together with the use of inverter technology. The compressor is radically innovative: magnetic bearings and digital rotor speed control allow partial load efficiency levels to be reached that were hither to impossible.
