Motorized Impeller Fan Array

Overview

Smaller footprint, higher efficiency.

An electronically commutated motor (ECM) array that addresses the application and installation challenges faced when selecting and installing an air handler fan section.

Available up to 70,000 CFM
Array features AMCA 207 wire-to-air efficiency
Fan size and quantity are selectable for every cabinet size, making it easy to optimize your selection

Compact Footprint Simplifies Installation

Motorized Impeller Fan Array features a compact footprint that can be specified to fit through a space as small as a single door, simplifying installation even in a retrofit.
Built for Your Needs

Static pressure capabilities as high as 9 inches w.g., allows an MI fan array to meet a range of applications. Select up to 15 fans and specify an array configuration to fit your specific space requirements. Choose from 5 wheel diameter options based on your balance of performance and price-point.
Redundant Performance

You can count on Trane’s Motorized Impeller Fan Array to continue meeting the space requirements during crucial moments. In the unlikely event that one of the fans should go down, the remaining fans continue to deliver the required airflow.
Reduced First Cost

Can offer reduced costs in both casing and installation due to reduced footprint when compared to a traditional air handler. Motorized impeller control panel (MICP) reduces footprint and simplifies power connection, reducing unit and electrical costs via simplified installation and maintenance.
Engineered for Efficient System Design

Construction features evenly distributed fans for consistent airflow across coils and filter while multiple motors enable a smaller electrical load. The Trane Motorized Impeller Fan Array performs more efficiently at part load than conventional fan technologies, reducing electrical draw.
