Corporate Strategy

Corporate Strategies

Since THI's incorporation, our primary goal has been to become one of the preeminent fired heater companies in the world. THI's strategies to accomplish this goal are:

  • Establish THI as a forward-thinking company known for customer service and superior products.
  • Continuously develop our technical and managerial capabilities.
  • Create an environment that makes our clients want to entrust THI with projects on a continuing basis.
  • Enlist the services of experienced and dedicated employees.

Continuous Growth

As a result of executing our strategic goals, THI has experienced some dramatic changes since 1985:

  • Direct employee workforce has grown from four to 40+ employees, representing over 350 years of direct-fired heater experience.
  • Indirect staff has increased to 200-300 employees.
  • Established long-term relationships with all domestic major energy, petrochemical, and engineering/construction companies. Included in this list are multiple projects with BP, Chevron, Phillips 66, ExxonMobil, Shell, and Valero in the domestic market.
  • Expanded our marketing area from the USA to all of North America, Central America, South America, the Middle East, and Asia.


THI has successfully completed projects for clients in Azerbaijan, Brazil, Canada, China, Colombia, Ecuador, Great Britain, India, Indonesia, Israel, the Netherlands, Japan, Kuwait, Malaysia, Mexico, Nicaragua, Nigeria, Panama, Peru, Russia, Saudi Arabia, South Korea, Spain, Taiwan, Thailand, Venezuela, and Yemen.

At THI we realize we cannot be all things to all clients, nor are all clients compatible with THI's corporate strategy. We also understand that we cannot achieve the level of quality and service that we seek if we only sell products based on price. With this in mind, we have sought to align ourselves with major clients who place a high value on good service, high-quality products, and strong technical expertise.
