Chiller SyScroll 20 to 35 Air NEW Air Cooled Water Chillers Cooling Only and Condensing unit Engineering Data Manual 20.0 to 33.
SyScroll 20-35 Air | Key points R410A refrigerant. Simpler refrigerant circuit layout with only one compressor. Great accessibility to internal components for service operations. Aeraulic independence between refrigerant circuit and condensing side. New display on external panel allowing the complete control of the unit. Wide operating limits. Low water temperature applications in cooling mode (down to -8 °C). Improved acoustic performances. New fan motor with integrated grill & condenser.
| SyScroll 20-35 Air Specifications CO = Cooling Only; RE = Remote Evaporator; 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 and remote evaporator (RE) versions. Each version consists of 4 sizes and covers a nominal cooling capacity range from 20.0 to 33.0 kW. All units are equipped with one scroll compressors.
SyScroll 20-35 Air | Condenser fans Units are equipped with two 500mm diameter axial fans with profiled, sickle shaped blades designed with bionical know how, optimized full bellmouth with static blades (motor suspension) and short diffusor. They are placed directly in front of the coil in order to increase the air flow and the heat transfer between air and refrigerant. Fan motors have IP54 protection grade, and thermostat protection placed in the bearings. Both fans are equipped with a safety grill.
