Water cooling

Cooling-water inlet temperature

Depending on the cooling-water temperature and the ambient temperature, meausres must be taken to provide protection against condensation in accordance with the engineering information If antifreeze is added, the perfomrance of the cooling system is reduced (lower heat conductance and greater viscosity). Recommended antifreeze is „Antiforgen N“ available from Clariant (Internet address, see below ¹).The antifreeze agent is intended to prevent damage in the event of plant shutdown and frost. Operation at temperatures of <0°C is not permissible even when antifreeze is used!
