Electrical Power Panel: Equipped with MCB switch for compressor and motor-fan.
Optional Features: Oil separator, crankcase heater, solenoid valve, anti-corrosion coil coating, and back-flow damper.

Installation and Operation

Electronic Version: Features xWING electronic controller for condensing and evaporating units.
Electromechanical Version: Designed for on/off operation with simplified installation.

Performance Data

Includes cooling capacities and specifications for various models under different conditions.
Sound pressure levels and power supply details are provided for each model.

VRC System

Adjusts refrigerant flow to match evaporating unit demand, maintaining constant suction line pressure.
Ensures reliable operation and compressor protection from overheating.

Conclusion
The document highlights the advanced features and specifications of the Sigilus-multi and intarbox-multi series, emphasizing their suitability for centralized cooling in various refrigeration applications.

Additional Specifications

The VRC system includes pressure and temperature regulation valves, adjusting compressor capacity from 100% to 10%.
Factory settings allow minimum evaporation temperatures of -13 ºC for positive and -35 ºC for negative temperature units.

Operational Procedures

System switches on/off based on low pressure values, with an external on/off switch option.
When demand is below 10%, the low-pressure switch triggers, turning off the compressor.

Selection Chart
Includes a quick selection chart detailing compressor horsepower, showcase and display lengths, and service requirements for both positive and negative temperature units.

Technical Features

Operates on a 400V-III-50 Hz power supply and uses R-404A refrigerant.
Optional features include anti-corrosion coil coating, back-flow dampers, and duct adaptors.

Performance Data
Tables provide detailed performance data for various models, including cooling capacity, nominal power consumption, maximum absorbed current, and sound pressure levels.
