Features And Benefits - Trane RTHD User Manual

Application Versatility and High
Performance
• Screw compressor technology and the
electronic expansion valve provide
reliable performance in an expanded
range of operating temperatures.
• Tight water temperature control extends
to operation of multiple chillers in
parallel or series configurations, offering
further system design flexibility for
maximum efficiency.
• Advanced design enables chilled water
temperature control to +/- 0.5°F (.28°C)
for flow changes up to 10 percent per
minute, plus handling of flow changes up
to 30 percent per minute for comfort
cooling.
• Two-minute stop-to-start and five-minute
start-to-start anti-recycle timer allows
tight chilled water temperature control
in constant or transient low-load
applications.
• LonMark communications capability
provides excellent, trouble-free
interoperability.
Applications in this catalog specifically
excluded from the ARI certification
program are:
• Low temperature applications, including
ice storage
• Glycol
• 50Hz units below 200 nominal tons

Features and
Benefits
• Generic Building Automation System
points are available for easy access to
operational information.
• Extensive information on professional
design selection and layout is available
in a simple, highly readable electronic
format.
• Standard model RTHD configurations
are in stock and available for immediate
delivery, and Trane offers the fastest
ship cycles in the industry for built-to-
order units.
• 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, and consistent
dehumidification.
Simple, Economical Installation
• Compact size makes the model RTHD
well suited for the retrofit and
replacement market.
• All units fit through standard double-
width doors.
• Bolt-together construction makes for
fast, easy unit disassembly.
• Small RTHD footprint saves valuable
equipment room space and alleviates
access concerns for most retrofit jobs.
• Lightweight design simplifies rigging
requirements, further reducing
installation time requirements and
costs.
• Full factory refrigerant or nitrogen and
oil charges reduce required field labor,
materials, and installation cost.
• Only evaporator and condenser water
piping is required; no starter water
cooling (with its associated safety
concerns) or field piping is necessary.
• Oil cooler and purge system
connections have been eliminated.
• Simple power connection simplifies
overall installation.
• Standard unit-mounted starter for
Wye-Delta and Solid State eliminates
additional jobsite installation
considerations and labor requirements.
• Trane has conducted extensive factory
testing, and also offers options for in-
person and/or documented system
performance verification.
• CH530 controls easily interface with
Tracer Summit ™ building automation
systems through single twisted-pair
wire.
