Abstract: Deconfinement phase transition due to disappearance of confining colorelectric field correlators is described using nonperturbative equation of state. The resulting transition temperature $T_c(\mu)$ at any chemical potential $\mu$ is expressed in terms of the change of gluonic condensate $\Delta G_2$ and absolute value of Polyakov loop $L_{\rm fund}(T_c)$, known from lattice and analytic data, and is in good agreement with lattice data for $\Delta G_2\approx0.0035$ GeV$^4$. E.g. $T_c(0)=0.27; 0.19; 0.17$ GeV for $n_f=0,2,3$ respectively.
