PräVis | Automatic water feed

to regulate the viscosity of adhesives

Product information "PräVis | Automatic water feed"

Glues in open glue trays lose moisture and viscosity due to movement, heat and dry air. To maintain the viscosity of the glue, a continuous and metered water supply is required. With the PräVis water may be supplied by two pumps, each to be controlled individually. In addition, the total amount of water to be fed can be regulated independently of the chosen ratio of the pumps. The settings are retained even after switching off the device. Set profiles may be saved and can be reloaded at any time. All settings are made on a back-lighted display. The display also indicates the level of the water reservoir or water leaks. Suction and venting of the hoses may also be controlled by the display.

Process

  1. First the unit is filled with water.
  2. Then the pumps are adjusted.
    • On the PräVis, each pump is adjustable in 10 stages.
    • Here, the switching frequency of the individual pumps is set.
    • The higher the level set, the shorter the pause between the pump cycles.
    • At level 10, the pumps are permanently active.
  3. The set value can be saved on the display so that this setting is active as the basic setting the next time the unit is started.

Advantages

The PräVis has an automatic water feed with an adjustable inlet point. Water is pumped in regularly via a self-priming system through hose lines and automatically fed to the open glue. This enables a constant viscosity without having to add water manually.

Various settings can be determined via the user-friendly display. Once suitable settings have been determined, they can be conveniently stored.
