Trane RTHD manual Features and Benefits, ApplicationVersatility and High Performance

Features and Benefits

ApplicationVersatility 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

•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, andTrane offers the fastest ship cycles in the industry for built-to- order units.

•Industrial / LowTemperature 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 strongTrane 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.
