AIR-COOLED LIQUID CHILLERS 30XAV 500-1150
230V electrical plug
230V AC power supply source provided with plug socket and transformer (180 VA, 0,8 Amps) 6 bar expansion tank in the hydraulic module (require option 116) New software algorithms to allow quick restart and fast loading while preserving unit-reliability 3G router board NOTE 1: require option 149 NOTE 2: when more than one machine is installed on site, only one of them shall be equipped with option 298 while all of them must be equipped with option 149 NOTE 3: if a CARRIER-PSM is on site, option 298 shall be integrated in the PSM while option 149 is still mandatory for each single unit. Hydronic control function package that permits control of the water ﬂow rate based on different possible logics (at customer choice): constant ΔT, constant outlet pressure and "ﬁxedspeed" control.
Permits connection of a laptop or an electrical device during unit commissioning or servicing Protects closed hydronic circuit from excessive pressure Full capacity recovery in less than 5 minutes after power failure. Matches requirements of typical critical missions applications Enabler for Carrier Connect service offer
Expansion tank Fast Capacity Recovery
Sizes 500/600 only 500-1150
Variable Water Flow control
When variable-speed pumps on the primary circuit, the VWF control modulates ﬂow rate through the evaporator, minimising pump consumption while ensuring safe/ optimised chiller operation
Features and advantages
Low energy consumption
The 30XAV is designed for high performance both at full and part load: ESEER up to 4,9 and EER up to 3,4. The high energy efﬁciency is reached through: - Inverter-driven twin-rotor screw compressors allowing precise capacity control and reducing unit power input, especially at part-load - Inverter-driven fan motors minimising power consumption while granting optimum air ﬂow - All aluminum condenser with high-efﬁciency microchannel coils technology - Flooded shell-and-tube evaporator characterised by high efﬁciency of heat exchange - Electronic expansion device permitting operation at a lower condensing pressure and improved utilisation of the evaporator heat exchange surface (superheat control) - Economiser system with electronic expansion device for increased cooling capacity. Optimised electrical performance: - Negligible start-up current (value is lower than the maximum unit current draw) - High displacement power factor (above 0.98) - EMC compliancy with Class 3 requirements of the EU standard EN61800-3 (Class 2 is possible as an option).
Built-in reliability and easy servicing
The 30XAV units offer increased global performance as well as Carrier’s acclaimed product quality and reliability. Major components are selected and tested to minimise failures possibility, as well as many design choices have been taken in this perspective. Screw compressors with Greenspeed® Intelligence: - The screw compressors are industrial-type with oversized bearings and motor cooled by suction gas, with a proven failure rate lower than 0.1%. - The inverter is speciﬁcally sized for each compressor motor to ensure reliable operation and easy maintenance. - All components related to the compressor assembly are easily accessible on site minimising down-time. Fans with Greenspeed® Intelligence: - 4th generation of Flying Bird fans equipped with inverter-driven asynchronous motors - The inverter is sized to manage a group of fan motors reducing ﬁrst cost while ensuring optimum air ﬂow management. - The inverters for fan speed control are easily accessible on site for easy servicing.
