SyScroll 40-75 Air | Key points R410A refrigerant. Simple refrigerant circuit layout with one compressor tandem. Great accessibility to internal components for service operations. Aeraulic independence between refrigerant circuit and condensing side. Low sound level for BLN unit, very low sound level for SLN unit. New display on external panel allows the complete control of the unit. Wide operating limits: Low water temperature applications in cooling mode (down to -8 °C).
| SyScroll 40-75 Air Specifications Sy Scroll SIZES Air - CO HP RE BC HT HPF CO = Cooling Only; HP = Heat Pump; RE = Remote Evaporator; BC = Brine for Process Cooling Application. General The new SyScroll Air air cooled water chillers have been designed and optimized to operate with R410A refrigerant fluid. They are available in cooling only CO, heat pump HP, remote evaporator (RE) and brine for process cooling application versions.
SyScroll 40-75 Air | Air cooled condenser coil Outdoor heat exchangers are finned tubes coils. Coils are built with internally grooved copper tubes expanded into corrugated aluminium fins. Fin pitch is differentiated between the two coil configuration (condensing only, reversible) in order to optimize operating conditions. Condenser fans Each unit has one axial fan, fixed speed type, 800 mm diameter.
