  The two-Equation of State (Two-EoS) model is used to describe the
hadron-quark phase transition in dense-hot matter formed in heavy-ion
collisions. The non-linear Walecka model is used to describe the hadronic
phase. For the quark phase, the Nambu--Jona-Lasinio model coupled to
Polyakov-Loop fields (PNJL) is used to include both the chiral and
(de)confinement dynamics. The phase diagrams are derived from the Gibbs
conditions and compared with the results obtained in the Hadron-NJL model
without confinement. As in the Hadron-NJL case a first order transition is
observed, but with a Critical-End-Point at much higher temperature, consequence
of the confinement mechanism that reduces the degrees of freedom of the quark
matter in proximity of the phase transition. Particular attention is devoted to
the phase transition in isospin asymmetric matter. Interesting isospin effects
are found at high baryon density and reduced temperatures, in fact common also
to other quark models, like MIT-Bag and NJL model. Some possible observation
signals are suggested to probe in Heavy-Ion Collision (HIC) experiments at
intermediate energies.
