The Great Southern Technologies (GST) is a specialty engineering company that encompasses unique creative & custom design methodologies to all new and used direct fired heaters and auxiliary equipment. As an InServ company, GST also incorporates optimal constructability methods to every project that allows for minimum turnaround duration and cost.

The integrated concept that makes up InServ’s core business objective affords the ability to provide the client a single source from conception to installation. This type of project execution reduces potential problems during installation and eliminates the risk of back charges typically experienced when required to work with a number of different companies for a given project.
