VTS enters the ‘green way’

Published:  11 October, 2017

The company’s Volcano water air heaters and Wing air curtain products are now equipped with energy efficient EC motors.

The motors used in the industry have a significant share in the global consumption of electric power. These values are so great that not only the motor users, but also parliaments in many countries are interested in their reduction. The European Union has been publishing appropriate regulations, imposing an obligation of using increasingly more efficient drives on manufacturers of electrical devices.

The heart of every air-handling unit is a fan assembly, i.e. a fan rotor driven by a motor. It decides the main parameters of device operation. VTS engineers, while drawing on their long-term production and exploitation experience, optimised in aerodynamic terms the form of the Volcano’s axial rotor and the radial rotor in Wing, which ensured the maximisation of efficiency.

What is the EC motor?

EC motors are brushless, direct current, electronically commutated motors, with coils in the stator and permanent magnets in the rotor. Thanks to the elimination of brushes – a part subjected to fast wear – EC motors are recognised as some of the most durable and reliable drives ever created. Elimination of brushes means that the bearings remain the only parts considered as potentially subjected to wearing process in the motor.

EC motors are characterised by:

  • Less energy consumption in comparison to AC drives
  • Higher efficiency in wide range of performance
  • Higher durability
  • Less maintenance cost
  • Silent operation at high revolutions
  • Smooth regulation by means of 0-10 volts signal of MODUBS RTU protocol
  • Smaller physical dimensions at the same capacity
