Technological advantages

ACS inside: ALPENTA Control System – Advanced control of the cooling unit via main programmable microprocessor controller. Dynamic high pressure setpoint and several limiting functions maximize working efficiency at part load and in outdoor conditions close to the working limits.
ASS – ALPENTA Selection Software – allows you to design hundreds of energy configurations so that the device meets individual requirements for energy efficiency or other specific technical requirements of the project.

Standard equipment

  • Compressors – hermetic high-efficiency scroll compressor with axial and radial compliance crankcase heaters, internal overheating protection and discharge temperature monitoring.
  • Condenser – reliable aluminium fins and copper pipes exchanger.
  • Cooling circuit– condensation controlled by a high pressure sensor.
  • Hydraulic circuit – differential pressure switch and water IN/OUT pressure gauge
  • Evaporator – efficient braze welded stainless steel plate exchanger.
  • Casing – provides galvanized steel sheet metal painted RAL7035 provide long lasting resistance against corrosion.
