    COOLING SySTEM Special requirements for open and half-open cooling systems: Impurities Mechanical impurities in half-open cooling systems can be counteracted when appropriate water filters are used. Salt concentration The salt content can increase through evaporation at half- open systems. Thus the water is more corrosive. Adding of fresh water and removing of process water works against.

  • Page 65: Connection To The Cooling System

    • Pay attention to flux direction and check tightness ! • The cooling flow must always be started before starting the KEB COMBIVERT. The connection to the cooling system can occur as closed or open cooling circuit. The connection to a closed cycle cooling circuit is recommended, because the danger of contamination of coolant is very small. Preferably also a monitoring of the pH value of the coolant should be installed.
