Series R Helical Rotary Liquid Chiller - Page 602

The Series R^® Helical Rotary Compressor

• Direct-drive, low speed for high efficiency and high reliability.
• Simple design with only three moving  parts, resulting in high reliability and low maintenance.
• Precise rotor tip clearance for optimal efficiency.
• Suction gas-cooled motor. The motor operates at lower temperatures for longer motor life.
• Five minute start-to-start anti-recycle timer allows for closer water loop temperature control.
• Years of research and testing. The Trane helical rotary compressor has amassed thousands of hours of testing, much of it at severe operating conditions beyond normal air conditioning applications.
• Proven track record. The Trane Company is the world’s largest manufacturer of large helical rotar compressors. Over 50,000 commercial and industrial installations worldwide have proven that the Trane helical rotary compressor has a reliability rate of greater than 99.7 percent in the first year of operation — unequalled in the industry.

Microprocessor Controls With UCP2

• Microprocessor-based unit control panel (UCP2) monitors and controls chiller operation and associated sensors, actuators, relays and switches. Control unit is entirely factory assembled and tested.
• Proportional integral derivative (PID) control strategy for stable, efficient chilled water temperature control.
• Exclusive Adaptive Control™ design to keep chiller on-line under adverse conditions.
• Standard electrical demand limiting.
• Chilled water reset for energy savings during part load operation.
• Complete range of chiller safety controls.
• Easy to use operator interface. Panel displays all operating and safety messages with complete diagnostics information.
• Clear language display is easy to read. The Standard clear language display panel supports eight languages including English, French, German, Spanish, Katakana, Italian, Portuguese and Dutch. An optional display panel is available to display Chinese, Japanese Kanji, Thai and Korean languages.
• Generic building automation system points available.
• Over 120 diagnostics and operating points including chiller current draw, condenser pressure and evaporator pressure are standard displays.

Integrated Comfort™ System Interface

• Microprocessor UCP2 easily interfaces with Trane Tracer^® and Tracer Summit^® building automation/energy management computer for Integrated Comfort™ systems benefits; all with a single twisted pair wire.
