Why Use ECM Retrofit?

New generation of ECM (Electronically Controlled Motor) is designed to apply the Permanent Magnet motor and advanced control technologies to deliver high efficiency, quietness and comfort.

As well known, majority of current domestic houses have a 1 HP, 3/4HP or 1/2 HP PSC (Permanent Split Capacitor) induction motor for the HVAC system in US. Those PSC motors operate at a low efficiency about 55% and even below 30% if operating at low-speed mode. Usually, these are noisy too. In addition, the peak speed is limited to about 1050 Rpm and below.

There are some issues to have these PSC motors running at your home:

  1. Low efficiency: It wastes more energy that it should.
  2. Noisy: It produces noises, electromagnetically, mechanically acoustic noises.
  3. Restricted airflow: Due to the PSC motor low peak speed, the house rooms may often have low air flow issues.
  4. Fixed speed: The PSC motor speed is fixed and may go to lower when airflow resistance is bigger.
  5. Because of the increasing awareness of air quality, more heavy-duty filters are installed into the existing HVAC systems, which may cause further airflow restrictions.

The ECM retrofit system could provide an ideal solution to solve the issues without changing your existing system and simply to replace your current PSC motor at minimal cost.
