Securten EP is an alkaline liquid formulation, suitable for waters with a medium-low hardness, for the cleaning in re-use CIP of equipments subject to thermal exchange in the field of food and dairy industries. Securten EP is able to easily remove organic and inorganic residues from surfaces, while the presence of controllers of the water hardness allows a sufficient management of mineral salt. The formulation permits to delay in time the acid descaling stage. The presence of an anti-foaming agent enables its utilization even in systems with turbulence. Securten EP is particularly suited for all these one-phase washings where a conductivity automatic control is necessary.
