Sigilus series is a refrigeration split system for outdoor installation.

Sigilus units combine the latest refrigeration technologies with traditional tested solutions in a very compact design. They have a strong structure but also feature a reduced weight, and reduced refrigerant load. They are built in galvanized steel with weatherproof polyester paint, and comprise a complete electronic regulation with remote controller and digital condensation control, with fast cooling and night mode to improve the efficiency

Sigilus units are available in differents configurations:

  • MSF-N series: low-noise motocondensig unit and slim-type evaporating unit for positive temperature, from 0,7 to 7,6 kW
  • BSF-N series: low-noise motocondensig unit and slim-type evaporating unit for low temperature, from 0,6 to 4 kW
  • MSF-Q series: low-noise motocondensig unit and cubic-type evaporating unit for positive temperature, from 3,4 to 13,7 kW
  • BSF-Q series: low-noise motocondensig unit and cubic-type evaporating unit for low temperature, from 2,5 to 9,7 kW
