Technical Services
The Technical Services Group is dedicated to heater evaluations and improvements. With the experience and capabilities to transform and enhance all general fired heater designs, THI can retrofit every brand of fired heater. Globally we have executed over 1200 major project retrofits. Completed more than 700 engineering studies, and replaced thousands of spare parts.
Why Retrofit
Operating a heater beyond its original design conditions can be detrimental to the long term life of the heater. Materials may prematurely fail, emissions can increase, and overall efficiency can drop. By retrofitting the heater, additional throughput can be achieved without these harmful side effects. With our experience in both process and mechanical design, THI can provide solutions to meet your technical and financial needs.
