The Portable Heat Injector System continuously monitors the discharge temperature with an onboard Temperature Controller and automatically modulates the gas to achieve the desired discharge temperature. This is a unique and critically important feature for the heat treatment process. It’s a law of nature…the heat level within the structure will not become warmer than the discharge temperature. The Temperature Controller is preset with safe ranges of operation and Supervisory Limits can be set to prevent Operators from changing the settings above an acceptable level for specific processes. As an additional safety feature, the Air Intake temperature is monitored and will act as a thermostat to turn the burner off/on, but let the main airflow continue. This patented design also allows the air volume to be adjusted from the control panel (1,000-4,000CFM) while maintaining the discharge temperature. The Air Intake can be filtered, which will reduce the airflow, without affecting its clean burning characteristics. The control panel and burner box require a specialized tool for access and the gas valve is lockable. There are female connections on each end of the Gas Supply Hose to keep it primed and to prevent on-site leakage when the process is complete. There is an Emergency Stop switch on Control Panel to quickly enable anyone to shut it off.
