Indirect Fired Heaters
Indirect Heaters are used in a multitude of oil and gas dehydration applications. Water, Salt and Steam bath heaters all have distinct advantages based on the intended use. OTSO can select and advise clients on which type of Indirect Fired Heater fits their application and offer a custom design heater to accommodate desired results.
All our Indirect Heater packages function by liberating heat in a separate chamber. This chamber heats the water, salt, and steam media thereby transferring heat to the process stream to induce drying. The advantages of this process are reductions in scaling, plugging and coking due to an even transfer of heat throughout the system and lower interwall coil temperatures than direct fired heaters.
Indirect heaters are a staple of the oil & gas industry and power generation sectors and are often used in various types of industrial applications.
OTSO can design, size, engineer and fabricate custom Indirect Heaters to meet any application, regardless of size.

A reliable Alternative Fuel Source
High Heating of Light Liquid Hydrocarbons
OTSO Indirect Heaters can provide a reliable alternative fuel source when designed to vaporize light hydrocarbon liquids. Incorporating Propane vaporizers provide industries and municipalities with a reliable primary, backup, standby of peak shaving fuel option in cases where natural gas is unavailable.
ASME Code and National Board stamped coils are used to heat the liquid process stream to an extreme high heat environment to vaporize the liquid. The exiting vapor then becomes a fuel source. OTSO vaporization packages range in size from small 250gpm systems to 10,000+gpm applications. All systems are designed to meet industry standards for OSHA, Factory Mutual (FM) and Factory Insurance Association (FIA).
