PLG 2300 Series — Laskin Nozzle Based Liquid Particulate Generators

PLG 2300 Aerosol Generator Series — Nebulization of liquids at a very high mass flow range up to 300 g/h

Description

The PLG range is a custom engineered laskin nozzle based generator range which uses an adjustable air flow through a submerged nozzle system to generate liquid particles from a solution in a well defined size range. The PLG range is available in seven models split into three levels of mass concentration capability.

Temperature Control of Particle SizeIn order to be able to perform practical analyses and comparisons, liquid droplet based aerosols must be generated from fluids that are also used in the real world. Fluids such as water, DEHS, motor oils, lubrication fluids, white oil etc. differ significantly in viscosity, surface tension and density. Depending on the fluid, different atomisation principles offer particular advantages.

Depending on the application, a special nozzle with heating option is used to adjust the desired particle size distribution and concentration quickly and reproducibly.

The PLG 2300 range is available in 2 models:

PLG 2300 PLG 2000 is the standard generator for high mass flows upto approx. 300 g/h (depending on the material) with a flowrate from 15 — 75 l/min. It has built in heating capability (to 80°C). The aerosol generated has a mean number diameter of 1.5µm (DEHS) and max diameter of 10µm. It is ideal for testing filter systems with high air flows, e.g. test of cooling oil separators.

PLG 2300 S adds an automatic refill feature, which maintains the liquid reservoir at the correct fill level and allows continuous generation over several days. This makes it particularly interesting for long-term testing of separators and filters perhaps over weeks.
