Fortunately, the company's China team is responsible for heating in winter heating Hua Xing Hua Fuzhou area community and further away from the pressure of demand on the system is different. "A dual-use equipment," the pump mode, the output pressure of the circulation loop is the same. To ensure the distant Whitford Community System pressure is normal, circulating pump output pressure is a big demand by the remote setting, for high system pressure does not need proximal users, only through the pipeline on the regulator to reduce the system pressure to ensure the safe operation of the system, resulting in waste of energy.
