range of crystal metering devices is enriched with a new
version of extremely pure spherical polyphosphate/silicate
elements.The particular spherical shape permits greated
regularity in the consumption of the product and consequently
better metering. The presence of silicate also ensures greated
protection of the metal parts against corrosion from water.
range of Opur metering devices goes up to 1 -1/4" and
the version with sphrical polyphosphate/silicate elements
is also available in these models.
For both models, the spare part is a practical trasparent
