Lumiglas Spray Device – Automatic Cleaning for Circular Sight Glass Fittings

The Lumiglas Spray Device is engineered to provide intermittent or continuous automatic cleaning of the underside of circular sight glass discs, ensuring clear visibility even in the most demanding process environments. Designed for use with circular sight glass fittings to DIN 28120 and similar, it supports both pressure and vacuum vessels across a wide range of industrial applications.

Suitable for installation in both explosion hazardous and non-hazardous areas, the spray device maintains optimal viewing conditions by jetting water, inert gas, or other compatible cleaning media directly across the glass surface—without obstructing the operator’s view.

Key Features

  • Designed for circular sight glass fittings to DIN 28120 and similar standards
  • Automatic cleaning of the underside of the sight glass disc
  • Suitable for pressure and vacuum vessels subject to standard pressure test certification
  • Approved for use in Ex and non-Ex environments
  • No interference with the viewing area during operation
  • All contact parts in 1.4571 stainless steel (or other specified materials)

Cleaning Media & Operation

  • Configured to jet spray water, inert gas, or other fluids across the glass
  • Supports intermittent or continuous cleaning modes
  • Ensures sustained glass clarity in processes prone to fouling, coating, or condensation

Typical Applications

  • Process vessels, reactors, and stirred tanks
  • Pressure and vacuum vessels with sight glass observation
  • Chemical, pharmaceutical, and food-processing lines
  • Any installation where continuous sight glass visibility is critical

The Lumiglas Spray Device is the go-to solution for maintaining clear, reliable process visibility through circular sight glasses—minimising manual cleaning and maximising uptime in both hazardous and non-hazardous plant environments.
