An ECFanGrid project is a fan wall consisting of several EC motor turbines operating in parallel. ECFanGrid retrofit projects are mounted on a metal plate with all hardware to fit the internal dimensions of the AHU. This solution is intended to replace direct or DC drives, which consume a lot of energy and are costly to maintain. This solution ...

We often mention the advantages of modernizing an air handling unit with ECFanGrid, where the inefficient transmission fan is replaced by a series of EC fans arranged in a matrix within the AHU. In the installation shown below, the new, highly efficient fans deliver an air volume of 50,000 m3/h. All fans in the unit are controlled at a single ...

How does an EC motor work? The EC (electronically commutated) motor is a synchronous motor powered by an inverter with permanent magnets in an external rotor design. The stator is driven by electronic switches controlled by a microcontroller. The motor needs to be supplied with AC voltage and a DC voltage signal to operate.The mains voltage, ...

Dam air curtain is part of the standard range of Airtècnics' air curtains. One of the applications that make the Dam air curtain unique and very special is the application of the Twin system in the installation. Dam Twin system consists of installing two Dam air curtains, facing each other vertically with the jets reversed, i.e. the ...
