Indirect process heating efficiently transfers energy to any low temperature process medium (cryogenic to 250°F). Heat transfer via an atmospheric water bath is an ideal method for heating combustible substances.
Common Applications
- Liquid petroleum gas vaporization
- Counter Joule-Thomson effect
- Dewpoint Heating
- Prevent low temperatures in pipelines
- Low temperature slurry heating

Newpoint Process Bath Heater Design
Newpoint Thermal offers a wide variety of process bath heaters to fit your indirect heating applications. Process bath heaters are available from 0.5 to 25 MM Btu/hr, and multiple unit systems can be designed for larger applications. Process coils are designed and manufactured to ASME Section VIII standards and rated to meet your pressure and temperature requirements.
Newpoint process bath heaters can be designed for indoor, outdoor or hazardous area classifications, and system components meet FM, IRI (GE Gaps), NFPA, UL, or other applicable standards. Control options are virtually limitless with relay logic and programmable logic systems available. User interfaces can be as simple as indicators and push buttons or as advanced as touch screen control.
Forced Draft vs. Natural Draft Heaters
Forced or natural draft heater designs are available depending on your specifications. An induced or "natural" draft burner relies on a stack to create negative pressure at the burner inlet, which induces as much air as is required for combustion. These heaters are popular for remote locations and/or locations with limited electrical service. Forced draft heaters are a more modern option utilizing small bore firetubes in conjunction with a combustion air fan. High velocities in the small bore fire tube reduce the "dead gas film" region along the tube walls. This results in tube areas up to half the size of their large bore counterparts.; therefore, overall heater size is minimized creating a significantly smaller footprint while offering superior burner control compared to natural draft style heaters.
Inside a Process Bath Heater
A flame is projected into a submerged "fire-tube" located at the bottom of a horizontal cylindrical shelf. Energy is transferred through the tube wall to the surrounding bath fluid. By means of natural convection, the bath fluid then transfers the required amount of energy into a series of process coils located at the top of the heater shell. Process bath heaters are typically atmospheric with an expansion tank located on top to compensate for the change in bath fluid density and varying temperatures. Process bath heaters have few moving parts, require very little maintenance, and achieve an efficiency of 80% without the use of an economizer.
