What does ULV mean?

ULV stands for Ultra Low Volume and is defined as the lowest amount of liquid per unit area (chemical plus carrier) needed to achieve efficient disease and pest control. The volume of spray liquid is directly related to the droplet size, which is generally accepted as from 0 to 50 microns in the ULV spectrum, with 15-20 microns as the volume medium diameter (VDM).

What does LV mean?

LV stands for Low Volume and refers to a larger droplet size. The volume of spray liquid is directly related to the droplet size, which is generally accepted as from 50 to 200 microns in the LV spectrum, with 75-150 microns as the volume medium diameter (VDM). The LV method is used for spot treatment in targeted areas, and to reduce drift in larger applications.

What is a thermal fogger?

The thermal fogger, also known as a hot fog generator, uses heat from combustion to produce a fog. The SWINGFOG series is our line of portable hot fog generators. They are gasoline driven with a powerful combustion chamber, which makes it possible to apply oil based as well as water-based chemicals in an equivalent droplet spectrum, without degrading the active chemical. The fogging solution is injected in the air stream emerging at high velocity, and is dispersed into very fine aerosol droplets and distributed into a lightly suspending fog. Application can be employed by means of various nozzles for either the ULV (Ultra Low Volume) or the LV (Low Volume) method. The system has no mechanical moving parts, and therefore no wear.

What is an aerosol fogger?

The Swingtec aerosol fogger generates ULV droplets by producing an air stream of high velocity at low pressure, which is accelerated in the swirl vane of the nozzle system. This causes an under-pressure in the solution tank and conveys the chemical solution, which is atomized through the nozzle system to produce fine aerosol droplets. The under-pressure system allows the use of nozzles with relatively large diameters. Therefore, wettable powders can be applied without the danger of blocking the nozzle.

Which fogger is right for my application?

It depends on the application. Both thermal and cold foggers can be effective in pest control, and both meet the ULV standard of up to 5 liters/hectare with a corresponding droplet range of less than 50 m. The difference between the two foggers is in the droplet dispersal. In cold foggers the droplet is dispersed pneumatically in a jet stream or through rotation, but in thermal foggers it is thermo-pneumatically produced by injection of the preparation into the hot exhaust flow of the machine.

The major difference between the two systems is the capacity of the combustion chamber. In portable thermal foggers the power of combustion ranges from 17 to 25 HP, whereas the capacity of portable cold foggers is less than 2 HP. The droplet output capacity is directly related to the power output of the machine. Therefore, the output of droplets of < 50m is approximately 30 liters/hour with portable thermal foggers, and approximately 3 liters/hour with portable cold foggers. Due to the higher output capacity of the thermal fogger, an area can be treated much quicker with the thermal fogger as compared to the cold fogger (depending on operator performance).

What are the advantages of thermal vs. aerosol foggers?

Thermal fog generators Cold aerosol fog generators
  • Shorter application time due to higher flow rate
  • Dense, visible fog to observe distribution and drift
  • Lower concentration of active ingredient
  • People can avoid direct contact with visible fog
  • Little or no quantities of carrier substances
  • Reduced volume of output (but not of active ingredient)
  • Little or no smell caused by carrier substances
  • Lower noise level

What are the disadvantages of thermal vs. aerosol foggers?

Thermal fog generators Cold aerosol fog generators
  • Cost of carriers
  • Smell of oily carrier substances
  • Higher noise level
  • Requires some operator experience
  • Requires longer application time
  • Fog is not as visible and difficult to observe distribution outdoors
  • People cannot easily avoid fog cloud
  • Higher concentration of active ingredient

Who is Swingtec and why haven't I heard of them before?

Swingtec is the manufacturer of the Swingfog line of thermal foggers, and the Fontan line of aerosol foggers. They were formerly a division of Motan, which is a long established manufacturer of industrial machinery located in Isny, Germany. Swingtec in now a separate entity dedicated to the production and development of the Swingfog and Fontan line of fog generators. They have over 50 years of experience in this product field, and have distributors throughout the world. Swingtec is DIN EN ISO 9001 certified.

Who is Jasmic?

Jasmic is proud to be an exclusive distributor for Swingtec product line. We offer the complete Swingtec line of Swingfog thermal, and Fontan aerosol fog generators. We stock the replacement and maintenance parts for the machines, and we offer technical support by a factory-trained technician.

Does Jasmic also sell chemicals?

Jasmic does not sell any chemicals. We are strictly a distributor for the Swingtec line of fog generators. Chemicals can be purchased from a local or national supplier in compliance with state laws. Laws vary from state to state, whereas several states require certification to purchase and disperse restricted chemicals. Please check with your state's agencies for certification information, and always follow the chemical manufactures directions.
