A system for curing a wet coating of a coated substrate, the system comprising: a curing room configured to receive the coated substrate being displaced along a displacement axis , the curing room being dividable along the displacement axis into at least: an upstream curing section comprising an upstream catalytic infrared heating system for producing an upstream infrared radiation at an upstream radiation intensity to partially cure the wet coating while the coated substrate is being displaced through the upstream curing section along the displacement axis; and a downstream curing section comprising a downstream catalytic infrared heating system for producing a downstream infrared radiation at a downstream radiation intensity, being lower than the upstream radiation intensity, to further cure the wet coating while the coated substrate is being displaced through the downstream curing section along the displacement axis for producing a cured coating; characterised in that the system further comprises a ventilation system having: an inlet at one of the upstream and downstream curing sections; an outlet at the other one of the upstream and downstream curing sections; wherein the ventilation system recirculates from said one of the upstream and downstream curing sections towards said other one of the upstream and downstream curing sections the heated air stream produced in said one of the upstream and downstream curing sections. a curing room configured to receive the coated substrate being displaced along a displacement axis , the curing room being dividable along the displacement axis into at least: an upstream curing section comprising an upstream catalytic infrared heating system for producing an upstream infrared radiation at an upstream radiation intensity to partially cure the wet coating while the coated substrate is being displaced through the upstream curing section along the displacement axis; and a downstream curing section comprising a downstream catalytic infrared heating system for producing a downstream infrared radiation at a downstream radiation intensity, being lower than the upstream radiation intensity, to further cure the wet coating while the coated substrate is being displaced through the downstream curing section along the displacement axis for producing a cured coating; characterised in that the system further comprises a an upstream curing section comprising an upstream catalytic infrared heating system for producing an upstream infrared radiation at an upstream radiation intensity to partially cure the wet coating while the coated substrate is being displaced through the upstream curing section along the displacement axis; and a downstream curing section comprising a downstream catalytic infrared heating system for producing a downstream infrared radiation at a downstream radiation intensity, being lower than the upstream radiation intensity, to further cure the wet coating while the coated substrate is being displaced through the downstream curing section along the displacement axis for producing a cured coating; characterised in that the system further comprises a ventilation system having: an inlet at one of the upstream and downstream curing sections; an outlet at the other one of the upstream and downstream curing sections; wherein the ventilation system recirculates from said one of the upstream and downstream curing sections towards said other one of the upstream and downstream curing sections the heated air stream produced in said one of the upstream and downstream curing sections. an inlet at one of the upstream and downstream curing sections; an outlet at the other one of the upstream and downstream curing sections; wherein the ventilation system recirculates from said one of the upstream and downstream curing sections towards said other one of the upstream and downstream curing sections the heated air stream produced in said one of the upstream and downstream curing sections. <EOS>
