Summary:2088151 9202766 PCTABS00010 A method for continuously monitoring and reconditioning the liquid flow in heating and cooling systems, wherein the system liquid, for instance water which may possibly contain standard additives, such as alcohol or glycol, is monitored and reconditioned in several mutually sequential steps within an apparatus unit integrated with the system, by taking from the total or main liquid flow a part flow which is returned to the main flow subsequent to reconditioning. The reconditioning process includes the following steps - subsequent to viewing the liquid by means of a viewing glass: magnetic filtration for removing magnetite particles; filtering-off solid particles (fine particles); removing corrosive gases; deaerating the system; measuring pH, oxygen content and conductivity, wherein an optical and/or electrical alarm signal is given in the event of deviations from mutually related liquid control-values inserted in the apparatus, or in the event of disturbances in operation. Apparatus for carrying out the method consists of a system-integrated unit which includes auxiliary devices for carrying out said part-operations successively.
