Glycol chiller

Coolers in compact and silent construction for glycol or brine.

Description

Air-cooled, water or glycol condensing chillers, with silent operation and compact construction in galvanised steel bodywork and structure in polyester paint for outdoor installation.

  • Operation with water, glycol or brine.
  • Minimum coolant charge.
  • Integrated hydraulic circuit.

  •  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.
