Triol AT24, Line B (HVAC) application, 380 V/480 V/660 V/690 V

Triol AT24 VFD Line 4 is known for its multifunctional performance and flexibility in such spheres of application as ventilation and air conditioning. Due to its optimal construction this VFD allows realization of a big variety of tasks. This makes the VFD universal solution. This line can be identified by high quality, easiness of access and simplicity of operation
