AZ® 100 is a specific chemical conditioner for the anti-corrosion and anti-scaling treatment of closed hot water heating circuits which can be used indifferently in old and new systems, at high and low temperatures. AZ® 100 is a universal protectant that provides effective protection against all metallic materials normally present in systems (including copper and aluminium). The dispersing and stabilizing agents of the AZ® 100 deposits are effective with all types of high and low hardness water, keeping the exchangers efficient for a long time and avoiding possible blockages in the pipes that cause the pumps and control organs to block. AZ® 100 is a ready-to-use product. It does not contain nitrites and chromates, it is not acidic or caustic, it is not toxic and is not harmful to humans or the environment.
