Sigilus

•  230V 50Hz or 400V 3N 50Hz power supply. Available in 60 Hz. Others voltages by request.
• Hermetic reciprocating or scroll compressor, acoustically insulated, with discharge silencer (in hermetic reciprocating compressor), mounted on dampers, with internal clixon and crankcase heater.
• Large-surface condensing coil made of copper tubes and aluminium fins, with tropicalised dimensioning for ambient temperatures up to 50 °C.
• Low-speed, nozzle-mounted motor fans, dynamically balanced propellers and external protection grilles.
• Proportional condensing pressure control by means of fan speed variation (optional on single-phase models).
• Cooling circuit equipped with high and low pressure switches, ceramic filter and sight glass.
• Stainless steel plate heat exchanger.
• Electric power and control panel, with differential and magneto-thermal protection for compressor, fan/s and hydraulic pump.
• Hydraulic circuit made of copper pipe with threaded connections, fill/drain valve, air vent, flow switch, thermometers and inlet/outlet pressure gauges. Threaded connections.
• Liquid injection in low temperature models with R-449A.

• Built-in hydraulic unit with glycol circulating pump, expansion vessel, safety valve, mesh filter, air vent and filling valve (positive temperature models).
• Proportional condensing control (standard on three-phase models).
• Coil anti-corrosion coating.
• External coil protection grille.

Control panel

•  230V 50Hz or 400V 3N 50Hz power supply.
• Main switch.
• Multifunction electronic controller, with the following functions:
  • Compressor, fans and circulator pump management.
  • Proportional control of condensing pressure by varying fan speed (three-phase models).
  • Glycol inlet/outlet probes and evaporating temperature probe.
  • Safety control and operation alarms.
  • RS485 connection with MODBUS RTU communication protocol.
