SIGHT GLASS LUMINAIRES ASL 55-LED (ALU) AND ESL 55-LED (STAINLESS STEEL)

• The optimum solution in the harmaceutical and
  food processing industries, ideal for illuminating
  bioreactors, laboratory mixers and filters as well
  as the interiors of boilers, tanks, agitators,
  separators, pipes and other – usually sealed –
  vessels in operating environments that are not
  potentially explosive

• Independent of the pressure/vacuum inside the vessel
• Lumiglas lamps must never be used for sealing vessel
  openings in place of a suitable sight glass fitting.

Operating temperature

• Maximum permissible ambient temperature: 40°C

• Insensitive to vibration
• Long service life and high operational reliability
• Continuous operation for LED up to about 50.000 hours
• The ideal solution wherever fittings are difficult to access
• No heat radiation in the light port (cold light)
• No additional heat which would be undesirable for
  chemical and/or biological processes
• Extreme high-contrast lighting
• Two simple installation options are practice-proven:
  a) by means of a hinged mounting, or
  b) by fitting the luminaire over a special raised edge
  on the cover flange (ideal in aseptic and sterile areas)

• Luminaire shell and end cover; ASL55-LED: corrosion-resistant
  aluminium alloy ESL55-LED: stainless steel 1.4404
• Screwed cable gland M20 x 1.5
• Light port as a unit consisting of a ring (aluminium
  or stainless steel) and glass
• Mounting with hinged bracket:
  stainless steel 1.4301 (to be ordered extra)

• Dust-tight and waterjet-proof:
