With its modular, building-block construction, the M-Series air handler can be tailored to meet specific job requirements for new or existing buildings. A wide range of standard and custom-engineered modules can be arranged and stacked in any number of configurations to address application and space wide array of available components is key to fine-tuning the performance of the M-Series air handler.

3 The broad spectrum of fan, coil, filter and control options allows you to optimize the performance and efficiency of your air several air-handling manufacturers offer some custom features, most find it difficult to incorporate those features into their standard cataloged unit, which leads to increased costs and extended lead times. Trane has engineered many custom solutions - with tested performance data - for the M-Series air handler, without the cost and lead times associated with full-blown custom continues to develop new options for M-Series air Handlers , so that you remain firmly in control of performance and cost on every design project. 2005 American Standard Inc.

As a customizable cataloged air handler, standard components can be arranged to meet most commercial, institutional and industrial applications for the indoor air handler market.

7 Pre-engineered custom options expand that flexibility while ensuring proven, tested performance and dependability, and reducing the costs and long lead times associated with most custom units. Some projects call for an air handler that incorporates new, emerging technologies or a job-specific requirement. Trane s experienced team of professionals can tailor the M-Series air handler to meet these requirements. These factory-packaged specials deliver Trane quality, enable simplified on-site installation and 1. The M-Series air handler post-and panel construction makes it easy to stack modules-even coil DesignThe M-Series air handler design adopts a building-block approach that allows you to design a unit specifically for your project. 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 Footprint when StackedThe M-Series unit s post-and-panel construction design makes it easy to stack modules - even coil modules.

8 Reducing the unit footprint is very advantageous, especially in tight mechanical rooms. The structural integrity remains intact, even when the panels are removed (see Figure 1). Eases Retrofit, Renovation, and ReplacementBuildings age, usage changes, loads change, new technology emerges, codes and standards are revised. Change is inevitable. The M-Series air handler - with its modular components, bolted construction, and removable panels - readily lends itself to the special needs of the renovation, retrofit, and replacement markets. To integrate new features, simply separate the existing modules and add, enhance, or replace components. The M-Series air handler can be shipped in small segments (see Figure 2) that can easily be moved into tight spaces of existing FlexibilityOffers a Wide Variety of FansAn extensive array of fan types and options, including variable-frequency drives for modulation in variable-air-volume systems, further enhance the flexibility of the M-Series air handler.

9 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 acoustical, efficiency, and discharge 2. Building-block design eases retrofit, allowing segments to fit into tight spaces, such as and Benefits CLCH-PRC003-EN7 Figure 3. Typical airfoil (AF) fanFigure 4. Typical airfoil vaneaxial (Q) fanFan 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 fans (commonly called plug fans) with multiple or single discharges on the front, top, bottom, or sides of the module Airfoil vaneaxial fans (Model Q fan) with horizontal discharge for unit sizes 12 to 120, and vertical discharge for unit sizes 6 to 120 Each fan is rated in accordance with Standard 430 of the Air Conditioning and Refrigeration Institute (ARI), and all DWDI fans are ARI Standard 430-certified to assure published Coil PerformanceFlexibility characterizes the broad coil offering on the M-Series air handler.

10 The variety of types, sizes, arrangements, and materials available lets you customize a coil that is optimized for pressure drop and capacity requirements. Published coil performance is certified in accordance with ARI Standard is at the leading edge of coil technology. Through extensive laboratory testing and numerous job-site installations, Trane has developed a unique fin surface for its coil offerings. This enhanced fin surface brings the capability of 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 in excess of 625 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).
