Does the Geze T2000NV door closer require a low opening force?

The TS2000 NV offers no special advantage as far as ease of opening is concerned (it’s advantage is it’s adjustability).  Depending on the door and the building, we usually recommend a TS3000B slim cam door closer, which is especially suitable for care homes, hospitals & nurseries.  It has a guide rail and cam mechanism, both features contribute to a lower opening force.  But remember, if it’s a fire door, it must still meet fire regs, so a TS4000 EFS free swing door closer may be more appropriate.  If you’re not sure, discuss your requirements before deciding.
