Features and advantages
Nominal cooling capacities from 2800-10500 kW. Mix-match capabilities – a complete line of compressors and heat exchangers to ensure the optimal combination of machine components regardless of capacity, lift and efﬁciency speciﬁcations. Hermetic compressor – elimination of leak risks from the compressor/motor shaft sealing in an open compressor. Dual stage compressor with non-blade diffuser designed, combined with inner-stage economizer for chiller performance improvement and high lift application. The innovative two-stage compressor provides a dramatic range of capabilities. With a maximum LWT of 65°C and a minimum LCWT of -6°C, the 19XR two-stage centrifugal chiller is ideal wherever energy conservation and environmental protection are required. Variable speed compressor capability on 19XRV-E AquaEdge chiller - Improvement of part load efﬁciency and electrical performance. 19XRV/XR(V)-E equipped with a LF2 VFD that designs with total harmonic distortion (THD)<5% and fully meets IEEE519-1992 requirement. The 19XRV/XR(V)-E becomes a more cost-effective choice for installations with a high percentage of time operating at part load. Heat exchangers certiﬁed by the European pressure vessels code (PED), and all marine code certiﬁcations. Touch Pilot control system with strong control and monitoring function during chiller operation. The Touch Pilot control system applies a 10.5 inch high resolution touch screen, which can support more than ten language choices for customer, real time display of operation parameters with pictures makes it more human friendly and comfortable interface for operation.
Two types of unit-mounted variable frequency drives (VFDs): standard and high tier, to match different customer requirements in terms of cost and electrical performances (VFD available on 19XRE only) Refrigerant isolation valves allow the refrigerant to be stored inside the chiller during service Hot gas by-pass for surge prevention during operation at high condensing temperature or for optimized operation at low load conditions Spring isolators adapted for all chiller conﬁgurations Unit-mounted starter reduces machine installation time and expense (VFD available on 19XRE only) High-voltage motors available: 400V (19XRE only), 3kV, 3.3kV, 6.3kV, 10kV, 11kV CCN/JBus or CCN/BACnet: remote connection 21 bar water heat exchanger Waterbox with ﬂanges and counterﬂanges Nozzle with ﬂanges (water inlet/outlet with ﬂanges) Delivered in multiple sections sections to facilitate the installation Refrigerant leak detector module : unit-mounted sensor (not compatible with 19XRE with unit-mounted VFD)
