Heat Treatement Process

The patented Heat Injector™ System uses a unique process to heat and distribute the air,

different than any of the competition...the most energy efficient heat treatment for bed bugs.  

It was designed with the Operator in mind!


​​    The Heat Injector System requires very little clear space it the heat treatment area so it is not important to make the client spend a lot of time preparing the area.  There are lists of items that need to be removed from the heated space but everything else should be left in the area to be heat treated.  The amount of BTU energy it takes to heat the area is a function of both the area and the contents.  With all the contents subjected to the heat, there is a lower probability of carry-in reinfestation.

Heat Injector Placement

    Move the Heat Injector to the location of the bed bug infestation and position it within an outside doorway, or within the heated space. Install the Doorway Air Barrier or the Air Shell to isolate the motors and controls from the heated environment during heat treatments and to ensure the dedicated combustion blower is able to get fresh air for combustion. The motors and controls are outside the heated  to ensure safe operation and maximum equipment life.

Heat Distribution

Fabric Discharge Ports attached directly to the Heat Injector allow the flexible and lightweight mylar duct to be positioned within the structure to the most remote locations and the areas where the infestation is the worst.  There is a variety of fabric cinch configurations which connect and adjust the 25’ lengths of flexible duct to discharge the heated airflow into multiple locations within the structure.  The arrangement of the ductwork is made to fit every situation with up to 9 discharge locations.

​​Once the ductwork is positioned, turn on the airflow to ensure it is positioned well and the bindings are secure.  Some adjustment to the length may be required by putting more/less duct within the fabric cinches used to adjust the length.   Turn on the heat switch, set the desired discharge temperature and adjust the airflow to maximum.

While the heat is starting to fill the structure, the operator installs duct management stands to stack the ductwork and to make it easier to access the heated areas.  Doorway drapes on the top of open doorways force the colder airflow to be drawn from the room, through the structure and back to the Air Intake to be reheated. The Air Intake temperature is monitored and displayed at the Air Intake to indicate the progress of the heat treatment.  The temperature rises as the returned airflow going into the Air Intake isn’t able to dissipate the heat into anything within the structure.


    When the space is thoroughly heated as indicated by Air Intake temperatures in excess of 122-125ºF degrees, the Pressurization Process is initiated to force heated air through cracks and openings within the structure, where bed bugs might find harborage.  To Pressurize, just open the Gate by pulling a knob and drop the Damper by rotating the Damper Control.

The Pressurization Process draws additional air from the outside and puts more air into the structure than is being pulled from the structure which causes the excess volume of air to try to escape from the structure and in doing so, puts a positive air pressure within the structure to force  heated air at lethal temperatures through cracks and crevices in the structure.

Purge the Heat during tear-down

    With the Portable Heat Injector positioned as a barrier between the heated environment and the fresh air environment outside, the Doorway Air Barrier can be removed after the heat is shut off and Heat Injector adjusted to draw fresh air into the Intake to purge heat from the structure. The purge is typically done without heat, which allows the gas hoses to be packed while the structure and its contents cool off.  For the client’s quick return, the purge should continue until the temperature within the structure can be controlled by the existing HVAC System.

Immediate Heat at Regulated Discharge Temperature

  The Heat Injector was designed to produce the desired discharge temperature immediately (within about 60 seconds).  The discharge temperature is continuously monitored and automatically controlled to maintain the operator chosen setpoint temperatures even when the airflow is adjusted.  The automatically controlled discharge temperature prevents damage from overheating.

Recirculated Airflow

  The patented Heat Injector System allows the heated airflow within the structure to be recirculated.  This unique difference allows the air within the structure to be continuously recirculated and injected with heat.  

The competition has to continually heat the  fresh air up to some high temperature, sufficient to offset the heat loss on the external duct and exhaust air from the structure to allow the heated air to be pushed in and immediately blend to hopefully achieve a non-destructive blended air temperature.

Energy Efficiency

   No generator is required; the Heat Injector is powered by propane and plugs into any standard 120 volt outlet to operate the Main Airflow Blower.

The Heat Injector System with the patent pending HP Boost™ feature senses the static load from the duct and boosts the horsepower to increase airflow and thus increasing the Btu energy transfer. The maximum speed and the static pressure to transition into HP Boost are preset at the factory. The speed control system for the main motor protects against under voltage and overload.

The Heat Injector System has a dedicated fresh air combustion blower which allows the direct gas-fired heat to be injected into the recirculated airflow. There is no heat loss from ducts located outside the heated environment. There is no air heated or moved that isn’t useful in the process.

Discreet Heat Treatment

  The heat treatment is not obvious to the whole neighborhood because there are no external ducts and no noisy equipment.  The Modular design allows the Heat Injector System to go where the bed bugs are; the Assembly can be broken down into modules and easily moved to the desired location and reassembled.

Professional Grade

   There are gas pressure gauges at the Gas Manifold and at the Heat Injector to best communicate the status of the gas supply to the Operator.  An Hour Meter indicates the accumulated hours the Heat Injector was used to heat air. The 20’ electrical cord eliminates the need for an extension cord in most applications. The High Temperature Limit on the discharge has an automatic reset. Basically no maintenance and with foam filled tires, they never have to be inflated.
