Introduction
To meet a wide range of applications in
the medium-tonnage, water-cooled
market, Trane is proud to introduce the
model RTHD helical rotary liquid chiller.
The introduction of this next-generation
chiller an exciting step forward in
application versatility, ease of installation,
control precision, reliability, energy-
efficiency, and operational
cost-effectiveness. The new RTHD chiller
is designed to deliver proven Series R
performance, plus all the benefits of an
advanced heat transfer design and a low-
speed, direct-drive compressor. Important Design Advances
and New Features
Major design advances include:
• Higher full-load energy efficiency
reduces both operating and life-cycle
costs.
• CH530 controls enable:
- scrolling access to inputs and operating
information via the LCD touch-screen
display;
- freedom from interoperability
concerns with LonMark
communications;
- job-specific communication options
that allow greater reporting flexibility.
• Improved startup temperature
capabilities and reduced sensitivity to
condenser water temperatures
alleviate the most common startup
concerns.
• Removed Liquid Vapor Separator,
providing lighter unit weight and
simplified refrigerant piping, for less
expensive handling, separation, and
installation.
The industrial-grade design of the Series
R helical rotary chiller is ideal for both
industrial and commercial markets, in
applications such as office buildings,
hospitals, schools, retail buildings, and
industrial facilities. The linear unloading
compressor, wide operating temperature
range, advanced controls, electronic
expansion valve, short anti-recycle
timers, and industry-leading efficiencies
mean that this latest Trane Series R chiller
is the perfect choice for tight temperature
control in almost any application
temperatures, and under widely varying
loads.
