Description

Air-cooled small capacity glycol or brine chillers for low-noise operation and compact self supported casing built in galvanised steel sheet and polyester paint coating for outdoor installation.

• Indirect cooling systems.
• Operation with glycol water or brine.
• Reduced refrigerant charge.
• Built-in hydraulic group depending on the version.

• 230 V-I-50 Hz or 400 V-III-50 Hz power supply.
• Reciprocating hermetic or scroll compressor, acoustically insulated, with discharge muffler (in reciprocating hermetic compressor), mounted on shock absorbers, with internal klixon and crankcase heater.
• Large surface condenser coil, copper pipes and aluminum fins, tropicalised for ambient temperature up to 50 °C.
• Low rpm motor fans, mounted on nozzles with dynamically balanced blades and external protection grilles.
• Variable speed axial fan for proportional condensation pressure control (optional on single phase models).
• Refrigeration circuit equipped with high and low pressure switches, ceramic filter and sight gauge.
• Stainless steel plate heat exchanger.
• Electrical panel, with differential and overload protection for each compressor, fan/s and hydraulic pump.
• Liquid injection system for negative temperature models with R-449A.
• Hydraulic circuit made of copper pipe with flow switch, thermomanometer, air vent and drain valve. Threaded connections up to 2 1/2“.

• Hydraulic unit with glycol circulator pump, buffer tank, safety valve, mesh filter, air vent and fill valve.
• Proportional condensation control (standard on three-phase models).
• Anti-corrosion coil coating.
