There are two continuous loops in our Insect Eradication System. These are the heater loop and field loop.
- In the heating loop the Heat Transfer Fluid (HTF) which is an environmentally benign water-propylene glycol solution is heated to 210F. The HTF is drawn from a 400 litre reservoir and pumped through dual coil heaters and back to the reservoir. The coil heaters are rugged coils of pipe with oil fired burners that are designed for mobile applications. The burners heat the HTF in the coils before it is returned to the reservoir. Up to 500,000 Btu/H of heat is generated in the system that draws either bio-diesel or diesel from the integral 66 gallon fuel tank.
- In the field loop remote heat exchangers are placed in the areas that require insect eradication. Specially engineered rugged hoses are used to connect the remote heat exchangers to the Heat Assault. The HTF is drawn from the reservoir and pumped through hoses into remote heat exchangers and back to the unit for reheating. Only the heat is left behind in the target area. The heat exchangers are radiators with fans. A wireless temperature sensing and data logging system allows the operator to remotely track the temperatures of different locations in the target area. The goal is to rapidly raise the temperature to 120-140F. Once this is accomplished insects and their larvae, pupae and eggs are killed. We have focused initially on bed bugs, but the system also works on virtually any other insect.
