Carrier Releases New ECM Direct-Drive Fan Option

CHARLOTTE, N.C. – Carrier has released its electronically commutated motor direct-drive fan option for the Aero 39M commercial air handler. Adding the new ECM fan option enables customers to further improve the system’s energy efficiency. This improvement is another enhancement to the recently reinvented 39M commercial air handler product line that now offers customers greater flexibility with more features.

Electronically commutated motors are typically more efficient than today’s premium efficiency motors and consume less power than variable frequency drive AC motors. Onboard electronics determine the position of the rotor, which then provides an electronic pulse to actuate the motor windings.

These electronics control the speed and level of input power to allow the motor to efficiently deliver the correct level of airflow based on building demand. Since the variable speed control is built into the motor, it negates the need for an external speed controller, which saves cost, airway length and weight.

In addition to the addition of the ECM direct-drive fan option, the Aero 39M commercial air handler has many new features. It was one of the first units offered in North America with foam-filled, double-wall construction, resulting in panels with an R-13 insulating value. It’s now offered in more unit sizes, configurations and features than ever before.

The product line also offers Agion anti-microbial technology as a factory-applied optional coating for the inside panel skin. Registered with the Environmental Protection Agency for use in heating, ventilating and air conditioning applications, Agion suppresses the growth of microbes on the treated surface by releasing silver ions at a slow and steady rate, ensuring long-term protection over the product’s lifetime.

Carrier also offers Carrier AHUBuilder software that makes selecting and optimizing 39M air handlers easy, allowing HVAC engineers to model refrigerant-based cooling systems with confidence, generating a cross-plot to help determine the most efficient system possible. This software also allows the user to select fan systems at full-load and part-load for performance and sound, and feature assists in the selection of the most stable, most efficient and quietest fan available Carrier offers.
