VMF is a Variable MulTri Fluid total HVAC concept for simultaneous heating, cooling and 100% fresh air, with built-in EMS (Energy Management system).

Variable refrigerant, variable water and variable fresh air, all using 2 pipes and working together as one!

Single piece monobloc external unit (with the size of a classic AHU), in combination with IHU (internal hydraulic unit) transfer the energy of the refrigerant into water and fresh air, making the rooms 100% eco conditioned.
