M-Series Climate Changer™ Air Handlers

1 October 2001 CLCH-PRC004-ENM- series Climate changer Air HandlersFeatures and Benefits See CLCH-PRC003-EN for unit data and CLCH-PRC008-EN for fan performance data for unit sizes 3 12. See CLCH-DS-7 for unit data and CLCH-CS-7A and CLCH-CS-7C for fan performance data for all other unit M-Series Climate changer air handler is a superior cataloged air handler with extensive flexi-bility to meet the specific needs of your engineered application. With its modular, building-block construction, the M-Series air handler can also meet the needs of what have traditionally been custom air handler applications.

2 The M-Series air handler, with all of its options, is used in a wide variety of applications in the indus-trial and commercial market-places. Trane continues to develop new options for this cataloged air handler, so that you remain firmly in control of performance and cost on every design of features and benefitsFeatureBenefitBuilding-block design Eases retrofit, renovation, and replacement Allows stacked units to reduce footprint Allows a wide variety of fans and coils Optimizes coil and fan performance Allows cataloged units to be used in custom applications Enables flexible module arrangementEngineered construction and casing Provides sturdy unit construction for high performance and long life Provides strength to stack units with post-and-panel construction Enables flexible maintenance access to the unit interiorIAQ-ready unit Meets ASHRAE Standard requirements Lowers installation.

6 Choose the blocks you need from the wide range of standard and custom-engineered modules available, and arrange them to satisfy the air-handling requirements of the application. Also, with Trane post-and-panel construction, modules can be stacked to reduce the unit Retrofit, Renovation, and ReplacementChange is inevitable. As time passes, building loads change, new technologies emerge, and codes and standards are revised. The M-Series air handler building-block design (with its modular components, bolted construction, and removable panels) readily lends itself to the special needs of the renovation, retrofit, and replacement markets.

7 To integrate new features, simply separate the existing modules and add, enhance, or replace compo-nents. The M-Series unit can be shipped in small segments that are easier than entire units to move into the tight spaces of existing 1. M-Series unit interiorFigure 2. Building-block design eases retrofit Features and BenefitsCLCH-PRC004-EN5 Allows a Wide Variety of FansAn extensive array of fan types and options, including inlet guide vanes and variable-frequency drives for modulation in variable-air-volume systems, further enhance the flexibility of the M-Series air handler.

8 You choose the fan that best satisfies your supply and exhaust or return fan needs. The wide variety of fans and options lets you optimize the fan in the unit to best fit not only the airflow and static pressure requirements, but also the acous-tical, efficiency, and discharge types include: Double-width/double-inlet (DWDI) centrifugal fans with front, top, or bottom discharges in the following available types: Forward-curved (FC) Backward-curved (BC) Airfoil (AF) Single-width/single-inlet (SWSI) plenum, or plug, fans for unit sizes 21 and above with multiple or single discharges on the front, top, bottom, or sides of the module Airfoil vaneaxial fans (Model Q fan) with horizontal discharges as standard and vertical discharges as a custom option for unit sizes 12 to 80 Each fan is rated in accordance with Standard 430 of the Air Condi-tioning and Refrigeration Institute (ARI)

9 , and all DWDI fans are ARI Standard 430-certified to assure cataloged Coil PerformanceFlexibility characterizes the broad coil offering on the M-Series air handler, too. The variety of types, sizes, arrangements, and materials available lets you customize a coil that is optimized for pressure drop and capacity requirements. Cataloged coil performance is certified in accordance with ARI Standard is at the leading edge of coil technology. Through extensive laboratory testing and innumerable job-site installations, Trane has developed a unique fin surface for its coil offerings.

10 This enhanced fin surface brings greater velocities of air through cooling coils without causing moisture carryover. The industry is familiar with 500-fpm limits through cooling coils as a rule of thumb for moisture carryover. Trane s fin design extends this limit to 750 fpm, depending upon air conditions, coil size, and coil-fin type and spacing. Tested data for moisture carryover is incorporated in the Trane Official Product Selection System (TOPSS program). In cases where moisture carryover is possible, the TOPSS program alerts you to this fact with a moisture carryover warning.
