The patented Lotter-Roth thermal system, which was already introduced in the 02/2012 issue of CPI, enables precast concrete production facilities to be able to manufacture thermally active precast components for climate control in buildings (heating and/or cooling) in both a rapid and uncomplicated way. This Lotter-Roth thermal system has now cleared the last hurdle – proof of compliance with F90 and F120 fire protection stipulations – before market launch.
