1.2.1. Unit types by heat recovery type
All VERSO Standard air handling units are divided into 3 groups according to the type of recuperator (heat exchanger)
used:
VERSO R
- air handling units with rotary heat exchangers. Rotating wheel (rotor) of a rotary heat exchanger collects heat
or cold from the indoor air and transfers it to the fresh supply air. Recovered heat/cold capacity is changed by adjusting the
rotor speed. When heat recovery is not required, the wheel stops.

VERSO CF
– air handling units with counter-flow recuperators (heat exchangers). Plates of a heat exchanger come in
contact with different air flows and so heat exchange between extracted and incoming fresh supply air takes place. Amount
of recovered heat or cold is controlled by adjusting the air bypass damper position. When recuperation is not required, the
air bypass damper is opened and the heat exchanger is closed. This way, the outdoor air bypasses the heat exchanger and
flows directly in to the premises.

VERSO S
– air handling units without heat exchangers, intended solely for air supply to the premises. Fresh outdoor air is
heated/cooled to desired temperature with heating/cooling devices installed in the unit or air ducts.
