Damping & Closing Details

Effect of Temp. Variation

Working function of Damper vary according to ambient temperature. Damping properties decreases when temperature increase and vice-versa. The reason is Viscosity of oil used vary according to temperature. Damper performance return back to normal when temperature backs to normal. The right side graphs is showing estimation of lid faster closer with temperature rise..
