Dairy MPV is an alkaline liquid formulation, suitable for waters with a medium-high hardness, for the cleaning in re-use CIP of equipments subject to thermal exchange in the field of food and dairy industries. Dairy MPV is able to easily remove organic and inorganic residues from surfaces, while the presence of controllers of the water hardness allows to work even with waters with a medium-high salt content. 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. Dairy MPV is particularly suited for all those one-phase washings where a conductivity automatic control is necessary.
