The 23XL is available in capacities from 150 to 350 tons where 60Hz power is available; 130-300 tons in 50Hz areas.
At ARI (Air-Conditioning and Refrigeration Institute) standard conditions, the efficiency of the 23XL ranges from 0.59 to 0.67 kW/ton (0.168 to 0.191 kW/kW) at full load, and 0.52 to 0.60 kW/ton (0.151 to 0.174 kW/kW) Integrated Part Load Value (IPLV).
The 23XL is a positive pressure design utilizing either refrigerant HCFC-22 or HFC-134a.
With sound levels for an untreated machine as low as 85 dBA, the 23XL may be the quietest screw chiller in the industry. And the availability of an optional sound kit makes the 23XL ideal for acoustically demanding applications.
Yes, the 23XL will accept a start/stop signal from an EMS without additional hardware requirements. Additional energy management functions can be easily achieved with the addition of an inexpensive optional interface.
Yes, both customer witnessed and Carrier certified performance testing is available. But you should also be aware that the performance of the 23XL is ARI certified. This certification is maintained through a stringent program of independently witnessed periodic testing.
The 23XL is Underwriters Laboratories (UL) listed (CUL for Canada). Also, the refrigerant side of the machine is built in accordance with ASME requirements, assuring pressure vessel integrity. And, it is built in Carrier's ISO9001 listed manufacturing facility.
Yes, the 23XL compressor design features an optional variable compression ratio control for optimized dual-duty applications.
