Our skills

The New Standard for Heat Treatment.

David Krupp started by designing custom spray booths and exhaust filtration systems with the parts supplied by a previous employer. In 2004 a merger within that supplier caused SSI to develop the methods required to fabricate sheet metal. Brian Krupp, son of the founder, became the technical support to develop elaborate systems used to process custom sheet metal used in the Booth Bits Program. This process continues and is managed by Travis Estler, son-in-law to the founder, who now manages the sheet metal fabrication interface.

The patent process for the Heat Injector System was started in 2004 with the final patent granted in 2008. Brian assisted in the development of the Heat Injector System; with the first Industrial Heat Injector being built in 2010. They are now operational in many different applications heating both fresh and recirculated air with discharge temperatures designed for comfort heat or elevated cure temperatures. Brian now manages the production and technical support of the Industrial and Commercial Heat Injector.

The development of the Portable Heat Injector System was initiated by Kevin Krupp in 2010. The design utilizes the patented concept of the Heat Injector System with unique features that have been developed with additional patents filed. The 2014 Model is being released to market as the most energy efficient method for heat treatment…setting a new standard for heat treatment. Kevin manages the production and technical support of the Portable Heat Injector System.
