Large capacity refrigeration plants

Large capacity and compact industrial plants, with semi-hermetic compressors, V-shape condensing coils and in-built control board.


The intarWatt range consists of high-power air-cooled condensing unit for industrial applications. These equipments are characterised by a very compact construction designed for outdoor use, which integrates the semihermetic compressor set, air condensers with V-coil arrangement, and the control and power panel.

  • Low refrigerant charge.
  • Large cooling capacity.
  • Semihermetic compressors.
  • Great service accessibility.


  • DX condensing units configuration: Cooling circuit with parallel compressor rack and common condensation. With oil separators per compressor, common oil accumulator and level controls and electronic oil injectors for each compressor.
  • Multi-circuit configuration: Multiple refrigeration circuits, each consisting of one or two compressors and a V-shaped air condenser module with two motor fans. Each circuit incorporates oil separators and balancing lines.
