Features and Benefits
Application Versatility
• Industrial/low temperature process cooling – Excellent operating temperature range and
precise control capabilities enable tight control with single chiller or series configuration.
• Ice/thermal storage – Specifiers and operators benefit from dual setpoint control and industry-
leading temperature, efficiency, and control capabilities, plus outstanding support through
partnership with Calmac, a strong Trane partner providing proven installation examples,
templates, and references that minimize design time and energy costs.
• Heat recovery – Maximum condenser temperature exceeds those of previous technologies,
providing hot water and tight control that minimizes operating costs for the chilled water plant
and boiler/hot water heater, while also providing consistent dehumidification.
• Water to water heat pump – For multi-chiller systems where there is a base or year-round
heating load the RTWD can be used as a water side heat pump by utilizing ground or surface
water as a heat source. Leaving condenser temperature control option allows for the chiller to
be used and controlled primarily for the heat produced in the condenser.
• Dry Cooler – Allows for use with a closed condenser loop system that minimizes the potential
for cross-contamination of the condenser loop.
• Variable primary flow – Variable evaporator flow compensation allows multi-chiller systems to
vary the flow of water throughout the entire system (from the evaporator through the cooling
coils). This feature also provides additional system efficiency as the number of pumps and the
flow rate in the system are reduced. Standard 2 pass or optional 3 pass evaporator allows for
a wider range of flow capabilities.
• Series chiller configuration – For two-chiller systems all the system water passes through the
evaporators and/or condensers of both chillers to take advantage of system efficiency gains due
to thermodynamic staging as well as downsizing the upstream chiller.
• EarthWise system – Low flow and high temperature differential installations allow for reduced
pump and cooling-tower energy by decreasing the amount of water flow pumped through the
system. This results in downsizing of all HVAC and ancillary equipment which provides
installation and operational savings.
