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, and with internal thermal protection against overloads of the electrical motor 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.
