JBL ProCristal UV-C Water Clarifier

The new JBL ProCristal UV Water Clarifier is a totally new designed unit. While there may be problems with the plastic housing with other models during the years, the JBL Water Steriliser units are absolutely safe. Since the ultraviolet radiation continuously attacks the plastic housing, the burner now was placed in in an additional glass tube, which is isolated towards the housing with a stainless steel foil. The UV-C radiation is reflected thereby and no longer impinges on the plastic housing. By the reflectance of the UV-C light, the effectiveness is significantly increased at the same time. Compared to the previous series, the new water clarifier devices have a 50% higher efficiency. Another innovation are the corner pieces for a space-saving installation and universal hose adapter for all standard tube sizes. The connections of the device are suitable for piping with PVC fittings 1 1/2 inch. With the JBL Quick Connect two or more devices can quickly and easily be joined together to run as one unit.
