Forced air ventilation system

A specially designed ventilation system for buildings or areas where it is necessary or required to have a forced air ventilation, in which the extracted air can be polluted.

What is a forced air ventilation system

A specially designed ventilation system for buildings or areas where it is necessary or required to have a forced ventilation, in which the extracted air is (normall) polluted, for example:

gasses of polluted air with organic solvents, paint overspray, and so on. Like in “Zone 2″ area’s.

During the extraction of the polluted air (usually heated air in the cold season), from this lost heat we can recover at least 50-60% of heat (which is dependent on the outside temperature and humidity.)

Features

  • min 50-60% heat recovery system with a cross heat-exchanger
  • electric heating of the supply air
  • programmable Day & Night (= economic mode) using a control panel
  • motors driven by frequency inverters
  • pocket filter system for exhaust- and intake air
