With the LVC-LowVelocity, the proven technology of the compact TROX volume flow rate controllers has been perfected even further. It is optimised for low air velocities from 0.6 to 6 m/s in the duct and low differential pressures from Δp 30 to 300 Pa. It is insensitive to flow distortion with a compact construction length of 310 mm. The LVC-LowVelocity is suitable for ventilation systems according to the current German Energy Savings Regulation (EnEV 2009).

Simple handling on site saves valuable working time. The volume flow rate is set without the need for any additional equipment, and a built-in indicator light confirms the correct function.
