Product catalog summary
Overview
The document outlines the specifications and features of the Sigilus-multi and intarbox-multi series air-cooled low-noise condensing units. These units are designed for both positive and negative temperature applications, featuring advanced cooling capabilities.
Specifications
  • Tropicalised Design: Operates efficiently in ambient temperatures up to 50 ºC.
  • Acoustic Insulation: Triple-layer insulation minimizes noise.
  • Control Systems: Includes an inbuilt power board with optional electronic control and remote keyboard for managing the evaporating unit.
  • VRC System: Allows cooling capacity modulation from 100% to 10%.
Features
  • Compressor: Hermetic reciprocating compressor with noise insulation and shock absorbers.
  • Condensing Coil: L-shaped coil with copper pipes and aluminum fins, featuring anti-corrosion coating.
  • Fan Control: Proportional control of condensing temperature via fan speed.
  • Refrigeration Circuit: Includes high and low-pressure switches, ceramic dehydratant filter, liquid receiver, and sight glass.
  • Electrical Panel: Provides protection for compressor and motor-fan.
Optional Features
  • Oil separator for extended piping lengths.
  • Inbuilt solenoid valve.
  • Anticorrosion coil coating and protection grille.
  • Proportional fan speed control for condensing temperature.
Technical Data
Detailed tables provide technical data for various models, including cooling capacity, power consumption, and sound pressure levels.
Applications
Ideal for centralized cooling in commercial refrigeration, such as cooled displays and cabinets.
VRC System Features
  • Composed of mechanical components for high reliability.
  • Maintains constant evaporation pressure and protects against motor reheat.
  • Keeps compressing ratio within safe limits.
Condensing Units
  • Centralize cooling for multiple services, maintaining constant refrigerant pressure and temperature.
  • Evaporating units with higher temperature requirements should have constant pressure valves.
Temperature Settings
  • Factory settings allow minimum evaporation temperatures of -13 ºC for positive and -35 ºC for negative temperature units.
Operational Control
  • System turns off compressor when cooling demand drops below 10% of nominal capacity.
  • Controlled by low pressure values and external on/off switch.
Compressor Capacity Regulation
  • Pressure and temperature regulation valves adjust cooling capacity from 100% to 10%, reducing power consumption and preventing reheating.
Technical Specifications
  • Tables list models, cooling capacities, power consumption, and specifications for different temperature conditions.
  • Units categorized by temperature application, with details on dimensions, power supply, and sound levels.
Additional Features
  • Anti-corrosion coil coating and protection grilles.
  • Optional components and detailed refrigeration scheme included.
