Formulated specifically for cooling and recirculating water in the circuit with the restoration of raw water or water with a constant hardness exceeding 4.5 ° DH It prevents the formation of salt deposits by specifically and actively acting on solid particles (crystals, colloids, sludge, etc.) without continuous crystal growth, thereby creating a compact material that promotes the formation of mud inconsistently easily removed from the circuit. Its action takes place on cooling systems subject to continuous chlorination
