Vallox 51 MV enthalpy
Vallox 51 MV enthalpy
Vallox 51 MV is a small ventilation unit which provides an easy solution for dwelling-specific ventilation in small apartments. Only 349 mm deep, the compact ventilation unit can be integrated into kitchen cabinets or placed above a toilet seat, for instance.
In terms of space use, the quiet and energy-efficient Vallox 51 MV is an efficient solution for studios and one-bedroom apartments as well as smaller two-bedroom apartments. The optional magnetic mount cover panel gives the unit an elegant and seamless appearance, regardless of where it is installed. The annual efficiency of the unit is 77%.
The Vallox 51 MV unit can be registered with the free MyVallox Cloud service and connected to house automation (Modbus RTU and KNX). Alternatively, the ventilation unit can also be controlled with its control panel, a suitable cooker hood, or both. The integrated humidity sensor also boosts the ventilation automatically when necessary.
