MODULAR RV
DUOVENT

MODULAR RV units are not fitted with the regeneration exchanger bypass, but can be fitted with circulation or mixing flap (marked as
MX or C in the unit code). The mixing flap allows you to efficiently mix part of the exhaust air with fresh air or allows the unit to have a 100 %
recirculated air circulation mode. This mode serves particularly for pre-heating or pre-cooling to the required temperature. Inlet and outlet fans are
in operation in the circulation and mixing mode.
