  • Heating well stream fluids prior to phase separation


  • Higher thermal efficiency
  • Small footprint package
  • Quiet operation
  • Equipment enclosure allows for customized aesthestic-blending into natural environment (Enclosure is optional)
  • Instruments enclosed and out of the weather
  • Forklift pockets and lifting lugs for easy installation
  • Stack is not required to be as tall as stack on horizontal heaters


  • 63,000 BTU/hr.
  • 100,000 BTU/hr.
  • 200,000 BTU/hr.
  • 300,000 BTU/hr.
  • Please inquire about higher BTU/hr. ratings


A wide variety of accessories are available for TERI water-bath heaters, including simple pneumatic controls and sophisticated remote controls.


The complete TERI vertical heater system is composed of the following components, each designed to meet specific design criteria:

  • The Enclosure makes the unit more aesthetically pleasing and can be customized the meet the project's requirements.
  • The Process Coil is the pressure containing part designed in accordance with API 12K and ASME Section VIII Division 1 code requirements.
  • The Firetube is designed to efficiently transfer heat into the surrounding heat media. Burner operation is very quiet.
  • The Heater Shell is an atmospheric vessel designed in accordance with API 12K requirements. No vacuum system.
  • The External Expansion Tank provides corrosion protection of the heater shell, coil, and fire tube by keeping these components submerged in the bath.
  • The Heat Media is commonly a mixture of glycol and water which is blended to a consistency to provide for proper freeze protection.
