Triol AT27 variable frequency drive for fan

12/07/2016

One of the most successful energy management tools ever applied to building HVAC systems is the variable frequency drive (VFD). For more than 20 years, VFDs have successfully been installed on fan and pump motors in a range of variable load applications. To control flow & air volume of the fans, it needs a wind deflector, reflux valve or start/stop timer usually, and the large power ac motors are very difficult in start/stop frequently as the electric impact is in a high level, during this time, it’s absolutely will cause electric energy wasted and high current impact during start/stop of the ac motor.

A feature of the converter Triol AT27 is a cold reserve, mounted installation, ready to be put into operation at any time (30 – 40 seconds). Also, according to the Customers` requests, the system can be reconfigured to a hot standby (start after 1 – 2 seconds after the command). Note that the reliability of the VFD can operate in a break – without a backup for direct starting. Two-way communication between the drive and dispatching control, automatic operation and remote control does not require the constant presence of personnel at the facility. VFD also provides more precise levels of control of applications.

The most significant benefit to using a VFD is energy savings. By matching system capacity to the actual load throughout the entire year, major savings in system motor energy use are achieved. Due to the VFD drive can realize soft start and soft stop for the ac motors, it can avoid voltage surge during the motor’s start period to decrease the failure rate and increase its service life, and reduce the power system’s capacity requirements and power loss.

As a result, Triol AT27 works according to specifications and found fit for service. Customer already operates the equipment and leverages the resources of its enterprise.
