Ultra low volume (ULV) fogging machines are cold fogging machines that use large volumes of air at low pressures to transform liquid into droplets that are dispersed into the atmosphere. This type of fogging machine can produce extremely small droplets with diameters ranging from 1–150 μm.
Ultra Low Volume (ULV) fogging is used by pest control industry and cleaning companies. ULV refers to the droplet size (between 20–30 micrometers (0.00079–0.00118 in)) generated by these fog machines. This fine droplet size is known [3] as the optimum size for pest control. Traditional thermal fog machine technology has difficulty reaching ...
During 2001-2006, a total of 466 fogger-related illnesses or injuries were identified in the United States by the SENSOR-Pesticides program. These illnesses or injuries often resulted from inability or failure to vacate before the fogger discharged, reentry into the treated space too soon after the fogger was discharged, excessive use of foggers for the space being treated, and failure to ...
Ultrasonic hydroponic foggers can be used in conjunction with prior advances such as aeroponic misters or even ebb and flow systems to help improve humidity levels (mimicking a rainforest canopy) and increase nutrient absorption, thus boosting growth rates. Research into standalone fogger-supported hydroponic growing is underway.

The cold head contains a compression and expansion space, a regenerator, and a displacer. Usually the regenerator and the displacer are combined in one body. The pressure variations in the cold head are obtained by connecting it periodically to the high- and low-pressure sides of a compressor by a rotating valve.
