Corona - Oil Mist Generator (OMG)

The Corona OMG system produces an oil mist / fog of a consistent particle size and distribution throughout a wide range of pressures.

Developed from the aerosol generating systems that Corona have produced for over 40 years (used to challenge HEPA filters with known aerosol concentrations), the OMG uses precision components throughout to ensure reliable and consistent operation.

The independently heated and temperature controlled oil reservoir ensures that the oil under test is at a constant viscosity.

Adjustment of the particle size from 0.2 micron mmd is possible via a precision mixing valve regulator.

Oil mist / fog from the OMG can be passed through flexible ducting if required using optional ducting adaptors (1”, 2” and 3” available), or alternatively an extended nozzle can be fitted to allow entry into a pressurized system.

The OMG is equipped with a wired remote control. Wireless remote available as an optional extra.

The oil mist / fog media is stored in the OMG in a heated pressure tank, the temperature of which can be controlled to ensure a consistent and appropriate oil viscosity. Temperature control of the reservoir is via its own PID microprocessor controller, allowing independent control from ambient to 70°C / 158°F.

The heat exchanger within the OMG is controlled by a second programmable microprocessor controller, the parameters of which can be adjusted to suit the specific physical properties of the oil in question. The high watt density cartridge heaters within the heat exchanger are controlled via a solid state relay, which proportionally bursts power to the heat exchanger to maintain optimum response time with minimum overshoot.

Oil mist / fog can be produced above a minimum temperature alarm value, which can also be adjusted to suit the physical properties of the test oil. Once this state is achieved, oil mist / fog is produced by pressurizing the integral oil tank with an inert carrier gas.

A mixture of oil and inert gas is then passed through the precision, machine heat exchanger chamber. The oil is vaporized, and the resulting vapor condenses on exiting the heat exchanger to form a dense, controllable oil mist / fog.

Corona's CFC180 Oil mist / fog has been extensively tested by independent bodies, including the Health and Safety Executive to ensure that it is non toxic and non flammable, Copies of the Health and Safety Data Pack are available on request. However, risk assessments should be carried out prior to the use of other "oil types" through the OMG.

Corona recommends that only approved CO₂ or Nitrogen gas is used as a propellant.

Compressed air should not be used. It contains Oxygen and hence the risk of forming a flammable aerosol is increased.
