Thermal Fogging Machine Circulation Heaters
An engineer with a unique thermal application found Durex's website on the internet and contacted us regarding heating a mixture of chemicals used in a Thermal Fogging Machine. John Sidbeck, a Durex application engineer, called the potential customer to discuss the application in detail.
The application is to pump a premixed blend of 80% dipropylene glycol solvent and 20% Fungicide with the following specifications:
- Heat from ambient (34-105F°) to maximum 212°F at a maximum flow rate of 2-3 gallons per hour
- Flash point: 248°F
- Auto-ignition temperature: 700°F
- Minimum ambient temperature 34°F
- Particle size distribution for the fungicide:
The Solution: After detailed discussion, it was determined that the maximum power requirement would be 940 watts. John recommended Durex' DFX250 Cast Circulation heater as a solution. The DFX250 is a robust low mass circulation heater that provides a quick thermal response. The cast circulation heater assembly is a designed integral 316 stainless steel tube and tubular heater that are in a helix layout. This design maximizes heat transfer in variable flow rate gas and fluid applications.
