R290 intarWatt Full INVERTER

R290  chillers

Glycol, water or brine chillers with reduced R290 load and Full INVERTER compressors.

Description

R290 intarWatt FULL INVERTER chiller for water or glycol systems for outdoor industrial refrigeration applications with a reduced R290 refrigerant charge.

CONSTRUCTION

  • Compact construction with V-shaped condensers.
  • Self-supporting casing made of galvanised sheet steel with weather-resistant polyester coating. Removable side panels around the entire perimeter.
  • Sealed electrical panel, independent from the refrigerated compartment.

FANS

  • EC electronic fans with speed regulation by proportional control of the condensing pressure.

REFRIGERATION CIRCUIT

  • Semi-hermetic compressors with capacity control,unloaded start and crankcase heater and INVERTER drive on each compressor.
  • Refrigeration circuits made of annealed copper tubing with brazed joints, filter drier, ATEX high and low pressure switches, pressure transducers and temperature probes.
  • Stainless steel plate evaporator(s) brazed with pure copper and electronic expansion valve(s).

HYDRAULIC CIRCUIT

  • Chilled water hydraulic circuit made of stainless steel pipework (from DN100) or annealed copper (up to DN100), with filling/drain valve, air vent, electronic flow switch, inlet and outlet thermometers and pressure gauges.

SECURITY

  • ATEX fans for continuous ventilation of the refrigeration compartment.
  • Leak detector with audible and visual alarm.
  • Shunt trip coil for cutting off the power supply line to electrical components located in the refrigeration compartment.
  • Safety valve on the high- and low-pressure sides for common ducted discharge.
  • Independent power supply for the exhaust fan and leak detector, with residual-current and thermal-magnetic protection.

COIL

  • Microchannel condenser coil with Polyester Powder Coating treatment.

ELECTRICAL PANEL AND CONTROL

  • Programmable intarChiller electronic controller with refrigeration control with floating setpoint (external 0-10 V signal), condensing fan control with floating setpoint, pump control, external signal for Silence mode, alarm indicator light and audible leak detection alarm.

CONSTRUCTION

  • Silentblocks for unit installation. (Accessory)

FANS

  • Radial fans with vertical discharge.
  • AxiTop® diffuser(s) on condensing fan(s).

REFRIGERATION CIRCUIT

  • Heat recovery (20 or 100 % of condenser heat) for hot water production.
  • Kit for operation at low ambient temperatures (< -15 °C) with pressure control valves, liquid receiver and electrical panel heater (except WW-1).

HYDRAULIC CIRCUIT

  • Built-in or external hydraulic module with multiple configurations. See page 34.

COIL

  • Copper microtube coil with aluminium fins, except AWW.
  • Polyurethane anti-corrosion coating for copper microtube coil with aluminium fins, except AWW.
  • Anti-corrosion treatment for copper microtube coil with Alucoast® fins, except AWW.
  • Aqua Aero® anti-corrosion coating for copper microtube finned coil, except AWW.
  • Aqua Aero® anti-corrosion coating for microchannel coil.

ELECTRICAL PANEL AND CONTROL

  • Voltage and phase failure control.
  • Programmed spare electronic controller. (Accessory)
  • Electronic controller for heat recovery. (Accessory)
