  Several lattice models display a condensation transition in real space when
the density of a suitable order parameter exceeds a critical value. We consider
one of such models with two conservation laws, in a one-dimensional open setup
where the system is attached to two external reservoirs. Both reservoirs impose
subcritical boundary conditions at the chain ends. When such boundary
conditions are equal, the system is in equilibrium below the condensation
threshold and no condensate can appear. Instead, when the system is kept out of
equilibrium, localization may arise in an internal portion of the lattice. We
discuss the origin of this phenomenon, the relevance of the number of
conservation laws, and the effect of the pinning of the condensate on the
dynamics of the out-of-equilibrium state.
