The BAVIERA CRU is a closed-loop condensate recovery system designed for use in corrugators to optimize energy efficiency and heat transfer. It recovers and pressurizes condensates from the corrugator's steam chests and rolls, avoiding energy losses and maximizing efficiency. The CRU is placed in the boiler house and includes a vertical tank sealed at 18 bar, a condensate pump, and various controls to ensure optimal operation, including level, differential pressure, and warm-up controls. The system is maintenance-free and has a long lifespan due to its robust components and the excellent working conditions of its natural air-cooled mechanical seal. It can also recycle steam for use in low pressure services.
