Small reductions in fan speed = big savings. The ECM Modulator provides impressive energy savings by intelligently adapting the fan speed to the temperature of the air being delivered to the home. This greatly reduces the average energy consumption during the times that ambient conditions do not require full speed operation. While many manufactures are starting to adopt variable speed systems, FanHandler is the only one that uses the delivered air temperature for speed control. This allows us to safely run the blower at much more efficient speeds.

Blower motor upgrade 

The ECM4 and 4Z packages allow you to upgrade systems with existing PSC or x-13 style motors, to use a high efficiency variable speed ECM. By upgrading these outdated systems with an ECM 4 or 4Z package, your customers can see energy savings of 30% or more. For more information check out our Energy Savings Page.

Air Destratification 

The ECM Modulator provides unbeatable comfort by gently and continuously mixing the air, eliminating hot and cold spots in the home. This keeps temperatures even from room to room, and from floor to ceiling.

Eliminates Cold Drafts

With the ECM Modulator, air flow is directly tied to the air temperature, so when the heat comes on the air flow starts out very gently and ramps up smoothly with the air temperature. This completely eliminates the cold blasts of air that are typical of traditional furnace and heat pump setups.

These controls didn’t earn the name HVAC whisperer for nothing. The ECM Modulator achieves greatly reduced blower noise by gently ramping up the blower's speed to only what the system requires. Reduced speed means quieter air flow, and the smooth ramp means no more waking up the baby with that loud gust of air when the system comes on. These kits also replace the blower motor with an ultra quiet ECM that runs silently, so the only sound you hear is the air, that is now gently moving through the ducts.

While most systems only make use of your air filter, electronic air cleaner, or UV Light while there is a need for heating or cooling. The ECM Modulator is designed to run continuously, but at a greatly reduced speed. This maximizes the air purifying power of these devices because they are always in use, and the reduced air flow means they are working at peak efficiencies.

In many parts of the country high humidity can be a big problem. Proper humidity control can be very complex. It requires the perfect balance of air flow and cooling, to maximize the humidity reduction of a heat pump or AC unit. If the fan is running too fast, the system cannot properly dehumidify, but if it runs too slow you risk damaging the system. Many contractors will do their best to set the fan speed just right to keep you comfortable and your system safe, but with ever changing conditions this is not an easy task. But don’t sweat; let the ECM Modulator take care of it. The ECM Modulator makes this easy, as it continuously monitors the actual temperature of the delivered air, and adjusts the fan speed many times per second. This allows us to achieve greater humidity reduction than any other system, period.
