For applications that have the potential for significant operating hours with low entering condenser water temperatures in the 55 F to 65 F range, will the 17/19EX chiller line be the right choice?

Yes! Unlike most large centrifugal water chillers that are commercially available, the 17/19EX chillers use a variable orifice system as opposed to a fixed orifice for refrigerant metering. The system of 2 variable orifices that are between the cooler and the condenser insure that the proper refrigerant liquid level is maintained in the cooler under a wide variety of operating conditions. The ability to handle these low entering condenser water temperatures is one of the unique features of this line of equipment.
