The unit to be tested will be fed with an oil aerosol (flowrate and temperature adjustable) either in positive or negative pressure conditions. The immediate vicinity of the filter is temperature controlled. During the collection efficiency measurement the separated and the let-to-pass oil amounts are measured in dependence on the volumetric flow. They are automatically recorded, applying the gravimetric method, by means of an absolute filter. The amount of oil leaving the separator can be recorded online. Additionally, the leakage of the oil drain valve can be measured. The test rig simulates the operating conditions in typical fields of oil aerosol separator application. When recording the pressure control characteristic, the Մpressure in the crankcase" is simulated in dependence on the suction pipe pressure" for different flow rates. Test chamber (opened) with upstream and downstream test piece connectors, being adjustable for different test object sizes. Integrated in the rear plate the heater blower combination.

Atomizer Arosol Generator ATM 243 Large Droplet Generator LDG 244 Atomizer Aerosol Generator ATM 243 Aerosol Generator LDG 244 for coarse oil dosage The ATM 243 was specially developed to meet the requirements on test aerosol to be produced for testing oil separators (and is subject to utility model protection). Its design ensures a highly stable particle size distribution and concentration with high reproducibility and high aerosol output. The oil is atomized by binary nozzles. The binary nozzles as well as the carrier gas and the oil storage are heated to the required temperature. For special...
