Which is Better : Thermal Fogger Vs. ULV Cold Fogger Sprayer Machine

Fogging Machines have become essential tools in industries ranging from pest control to public health disinfection. Among the top contenders are Thermal Foggersand ULV (Ultra Low Volume) Cold Fogger Sprayer Machines. But the big question remains: Which is better?

The answer isn't as simple as one being outright superior it depends on where, how, and why you're using it. Let's dive deeper into both types of foggers to help you make the most informed decision.

Understanding the Basics

What is a Thermal Fogger?

A Thermal Fogger uses heat to convert a liquid chemical solution into a fog or smoke. It operates by heating oil-based solutions until they vaporize, creating visible, thick fog  that can travel great distances.

These foggers are especially popular for outdoor use, such as:

·         Mosquito and insect control

·         Agricultural spraying

·         Livestock shed sanitation

·         Outdoor disinfection during health emergencies

Popular Thermal Fogger Brands: Longray TS36S, IGEBA TF Series, Burgess Propane Foggers.

What is a ULV Cold Fogger ?

A ULV Cold Fogger, unlike the thermal type, does not use heat. It uses high-pressure air to spray fine droplets of liquid at ultra-low volumes. These droplets are so small that they stay airborne longer and can cover surfaces more effectively.

ULV foggers are best for indoor and sensitive environments, such as:

·         Hospitals, clinics, and laboratories

·         Offices, schools, and public transportation

·         Hotels, restaurants, and retail outlets

·         Residential homes for mold/mildew disinfection

Popular ULV Cold Fogger Models:  Longray 3600E, VectorFog C100+, and Bure ULV Pro.

When to Use Which?

Choose Thermal Fogger When:

·         You need quick action against mosquitoes, flies, or insects in open fields or public places.

·         You're treating agricultural lands, forests, or warehouses.

·         You prefer visible fog to confirm coverage.

Example: Municipal health departments often use thermal foggers during dengue or malaria outbreaks for wide-area mosquito fogging.

Choose ULV Cold Fogger When:

·         You need precise disinfection inside offices, homes, or healthcare facilities.

·         You're using water-based disinfectants or chemicals.

·         You want a low-noise, eco-friendly, and safe solution.

 Example: During the COVID-19 pandemic, ULV foggers were widely adopted for daily disinfection of indoor public areas.

Which One is Better Overall?

If you're looking for outdoor pest control, a thermal fogger is your best bet. It covers large areas quickly and is highly effective against flying pests. But for indoor environments, sanitation, and virus/bacteria control, the ULV cold fogger wins hands down.

For businesses in pest control, sanitation, or fumigation services, owning both machines gives the flexibility to handle every type of job, from fogging a hotel room to sanitizing a warehouse.
