Application: The relay is designed to provide control of fresh air feeding in bacterial purification stations during certain period of time. It is to be connected of the compressor/pump/ electrical grid in order to provide a fresh air into the bio-decomposition hopper. Thus the switched on programmable time relay feeds an air in the hopper depends on the selected program.    Technical data: It has five operating modes,...

  Application: The controller is designed for implementation in sewage water purification stations. It provides an air treatment during preliminary fixed and programmed time periods, as it is to be connected in the compressor circuit. In this way the controller provides a vital environment for micro-organisms and bacteria reproduction, which remove the water impurities.     Type 1 Technical data: Equipped with five outputs –...
