Description

Low noise condensing units for positive and negative refrigeration with hermetic alternative or scroll compressor with noise insulation and low speed axial motor fan.. These units are characterised by:

  • Tropicalised design for high ambient temperature up to 50 ºC.
  • Multi-service version with VRC cooling capacity modulation system.
  • Liquid injection system for compressor refrigeration.

Installation without electrical board (-N version)

 

 

Installation Sigilus condensing units

Versions

  • -N version: Without electrical board. Designed for on/off operation depending on the suction pressure (pump-down). With electrical board as an option. Electronic controller to manage the condensing unit and the evaporator built-in solenoid valve as an option.
  • -V version (multi-service): The multi-service version features VRC system to adjust the refrigerant flow to the demand of the evaporators, keeping the pressure constant in suction the line. The VRC system is composed of a set of pressure and temperature control valves to progressively modulate cooling capacity from 100 % to 10 % of its nominal capacity, while reducing energy consumption and preventing compressor overheating.
  • -S version (scroll). Version designed with scroll compressors.

 

  • 230V 50Hz or 400V 3N 50Hz power supply. Available in 60 Hz. Others voltages by request.
  • R-134a or R-449A refrigerant, other refrigerants by request.
  • Reciprocating hermetic or scroll compressor, acoustically insulated with discharge muffler, mounted on shock absorbers, with crankcase heater and internal klixon.
  • Large-surface condensing coil made of copper tubes and aluminium fins, with tropicalised dimensioning for ambient temperatures up to 50 °C.
  • Low speed axial motor fan.
  • Refrigeration circuit equipped with high and low pressure switches, ceramic filter and sight gauge.
  • Digital control of condensation pressure with the optional electrical board, and all-nothing condensation control in condensers without electrical panel.
  • Proportional control of condensing pressure through fan speed variation (included from MDF-NY-2086 and MDF-NG-1038 without electronic control).
  • Full control and power board with compressor and motor fan protection.
  • Liquid injection system for negative temperature models with R-449A.
  • Change to 400V 3N 50Hz power supply.
  • Built-in oil separator (already included in -V version).
  • Built-in solenoid valve with body and coil (except -V version).
  • Anti-corrosion coil coating.
  • Coil protection grille.
  • Proportional condensation control by fan speed variator (single-phase 1 series).
  • Control and power panel with electronic control unit for management of condenser and evaporator (except BDF-NG-0 018 model).
    – Larger sized multifunction electronic control
