Line heaters are used to maintain fluid temperature and prevent hydrate formation in natural gas and liquid hydrocarbon pipelines.
Fired heaters are commonly used in glycol dehydration systems to regenerate glycol used in natural gas drying processes.
Fired heater systems support production equipment including horizontal and vertical treaters, FWKO units, and thermal separation processes.
Industrial process heaters provide thermal energy for refining, petrochemical processing, and other industrial heating applications.
Fired heaters support gas conditioning, regeneration heating, and thermal treatment across natural gas processing and gas separation facilities.
Direct fired heaters transfer heat directly to process coils or fire tubes using combustion gases. Direct fired heaters are widely used for high-duty process heating applications requiring responsive temperature control and efficient heat transfer.
Common configurations include:
• Helical coil heaters
• Vertical cylindrical heaters
• Cabin style heaters
• API-560 process heaters
• Firetube / bath heaters
Indirect fired heaters separate the combustion system from the process fluid, using a heat transfer medium to deliver stable heating. Indirect heaters are often used when process purity, temperature stability, or safety considerations require isolation from combustion gases.
Common systems include:
• Line heaters
• Heat medium heaters
• Thermal fluid heaters
