General

TAC means "Total Airflow Control” technology, in other words «Technology of total control of the airflow». It rests on the construction of airflow algorithms, and exploits the latest developments in electrical motors such as the Electronically Commutated Motor, an intelligent DC driven. The motors are brushless, with permanent magnets, and are DC but AC powered.

PLC applies this technology to the airflow control since 1993. Today, we proudly present the 3rd generation of this product line.

Intelligent motor, intelligent fan :
The ECM motor is able to communicate instant accurate information on the motor’s working point. Using this information, we have built airflow models allowing instantaneous calculation of the fan’s actual working point. The result of these developments is available in the TAC3 product line.

The availability at any time of this information opens the door to numerous intelligent exploitations. The TACtech exploits this characteristic to pilot the fan according to the needs of the application.

Extremely high efficiency.
The efficiency of the DC ECM motor is very high, whatever its speed of rotation. It is included between 60 and 85 %, for a rotation speed included between 300 rpm and on 1800 rpm. This characteristic by itself already justifies the use of TACTech.
