Large capacity refrigeration plants

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


IntarWatt series are air condensed refrigeration plants, large capacity, designed for industrial applications. They are characterized by a really compact construction, ready for outdoors operations, featuring semi-hermetic compressors rack, V-shape condensing coils, and control board.

The plant configuration it is so versatile, allowing several circuits combination, double aspiration (high and low pressure), and ready for new low greenhouse refrigerants.

IntarWatt refrigeration plants advantages
  • Large cooling capacity: 50 to 500 kW.
  • Minimum space needs, outdoor operation.
  • Great configurations flexibility.
  • Multi-refrigerant.


Cooling circuit with compressors rack and common condensation. Oil separator per compressor, common oil accumulator and oil level control and oil electronic injector per compressor

Multi-aspiration plant configuration:

Cooling circuit with compressors rack with multiple suction and common liquid line, possibility of liquid subcooler addition for subcooler liquid line.

Multi-circuit configuration:

Multiple cooling circuit, each one composed by one or two compressors and an air-condensing module in V-shape with two motor-fans. Each circuit featuring oil separator, and balancing lines. Possibility of including liquid subcooler at different pressure circuits.

Double stage configuration:

Double stage compression cooling circuit for low temperature, with oil separators at high pressure, common oil accumulator and oil level control and oil electronic injector per compressor.
