DESIGN AND OPERATING LOGIC

• The unit consists of a protective internal grille with a decorative panel, a cartridge, an air duct with a sound-absorbing material layer, and a protecting external ventilation grille or a hood.
• The cartridge is the basic functioning part of the unit.
• The cartridge consists of a fan, a regenerator, and two filters that ensure rough air filtration and prevent the ingress of dust and foreign objects into the regenerator and the fan.
• The internal grille is equipped with manually actuated shutters to close the air duct during the unit standstill.
• The external protective grille on the outer wall prevents the ingress of water and foreign objects into the unit.

UNIT DESIGN

CARTRIDGE DESIGN

• The cartridge is a block consisting of removable filters and a solid fan-regenerator unit.
• The filters are easily removable for technical maintenance.

UNIT OPERATION MODES

• The unit has two ventilation modes:

Ventilation. The unit operates in permanent supply or extract mode at a set speed. In the case of two units operating in this mode one unit operates in supply and the other one in extract mode.
Regeneration. The unit operates in reversible mode with heat and humidity regeneration in two cycles, 70 seconds each.

Cycle I.

• As warm stale extract air flows through the ceramic regenerator, it heats up and moisturizes the regenerator and transfers up to 97 % of heat energy.
• In 70 seconds as the ceramic regenerator gets warmed, the unit is switched to supply mode.

Cycle II.

• Fresh intake air from outside flows through the ceramic regenerator, absorbs accumulated moisture, and is heated up to room temperature.
• In 70 seconds as the ceramic regenerator gets cooled down, the unit is switched to air extract mode and the cycle is renewed.
• In this operation mode, in case two units are installed each of them operates two cycles in opposite phases.
• While one unit operates in air supply mode the other one operates in air extract mode.
