Fired Heaters

HSI was established in 1988 as a Fired Heater fabricator. What set us apart was our commitment to perform all refractory installation with full-time HSI employees.  We are one of a select few fabrication companies who has the capabilities and experience to self-perform refractory installation. This approach helps keep schedules and costs in our control and removes the uncertainty of subcontracting.  Combining our experience with our innovative maximum shop assembly method reduces costs for our customers.
