Description
R290 Sigilus is the range of chiller in silent air-condensed construction for commercial refrigeration applications, using a low propane charge as the primary refrigerant contained in the chiller, and water or glycol as the secondary refrigerant for cold transport. These chiller plants are characterised by:
- A tropicalised design for ambient temperatures of 45°C.
- 100% factory tested equipment.
- Acoustically insulated scroll compressor.
- Built-in hydraulic unit (optional).
- Minimal R-290 refrigerant charge.
- Scroll hermetic compressor mounted on shock absorbers and acoustically insulated, with internal klixon and crankcase heater.
- Large area condensing coil, in copper pipes and aluminium fins, tropicalised for ambient temperature up to 45 ºC.
- Motor fan with proportional condensing pressure control by speed variation.
- Refrigeration circuit made of annealed copper tube equipped with ATEX high and low pressure switches, safety valves and filter.
- Hydraulic circuit made of copper pipe, with threaded connections, fill/drain valve, air vent, flow switch, thermometers and inlet/outlet pressure gauges.
- Electric power and control panel, with general differential protection, motor fan circuit breaker and compressor circuit breaker and thermistor.
- Electronic regulation with digital control interface.
- Acoustic and light alarm.
- Built-in hydraulic group.
- Protective grille for external coil.
- Polyurethane coating on the condensing coil.
- Scroll protection system for voltage drops and phase failures.
- Very low temperature condensation control.
