R290 intarWatt

Description

Water, glycol or brine chiller for outdoor industrial refrigeration applications. Also, the R290 intarWatt chiller is characterised by:

• Built-in hydraulic unit (optional).
• Low refrigerant charge R-290.
• No need for machine room.
• Plug & Play system.
• Optimised compact system, with minimum maintenance.

• 400V 3N 50Hz power supply. Available in 60 Hz. Others voltages by request.
• Reduce refrigerant charge of R-290.
• Manufactured with galvanised steel casing and polyester paint.
• Semihermetic compressor tandem for R-290 with capacity control and unloaded start, crankcase heater.
• Oil separator and oil balancing line.
• Micro-tube V condensing coil with aluminium fins and 7 mm copper pipes.
• Two electronic fans per V with variable speed.
• Plate heat exchanger with electronic expansion valve per circuit.
• Heat exchanger for liquid subcooling and suction superheating.
• Cooling circuit made of annealed copper or steel tube with soldered connections, filter drier, ATEX high and low pressure switches, pressure transducers and temperature probes.
• Hydraulic circuit made of copper pipe with threaded or flanged connections, fill/drain valve, air vent, flow switch, thermometers and inlet/outlet pressure gauges.
• External IP55 electrical panel with extraction fan. Individual protection of compressors and fans.
• Progamable Emerson control, with variable refrigeration control (digital compressor only), condensing pressure control with floating set point, and variable glycol flow
  control.

• Hydraulic group.
• Variable flow pump to control glycol flow.
• Anti-corrosion treatment based on polyurethane coating for the condensing coil.
• Electronic control and spare driver.
• Silentblocks for equipment installation.
• Heat recovery (20 or 80 % condenser heat) for hot water generation.
• Independent compressor compartment with leak detector and ATEX extraction fans.
