Get to Know Us Better

We conduct our own applied research at our 22,500 ft2 Research & Technology Center (RTC). This controlled testing environment houses multiple research units, along with support facilities and equipment. From the collected data, our research staff develops reliable heat transfer and pressure drop methods, which are then implemented in a variety of products and services that improve the design and simulation of process heat transfer equipment.

While our diverse team spans the globe, our headquarters is located in Navasota, TX, USA. This prime location offers proximity to key metropolitan areas, including Austin, Dallas, Houston, and San Antonio. The closest metropolitan city, Houston, is home to many of the world's leading energy companies. We also maintain a branch office in Guildford, United Kingdom.
