What Is Indirect Heating?

SAFETY - Eliminates Ignition source in the vessel reducing the risks associated with Firetube failures.
EFFICIENCY – Improved combustion efficiency reduces fuel consumption and emissions.
RELIABILITY – Uniform, low temperature heating extends equipment life.
FLEXIBILITY– In vessel or circulation systems can be used with gas or electric heat sources.
ECONOMICS – Reduced maintenance and reduced spacing shorten ROI.
A Safer, More Efficient Way to Heat Oil & Process Fluids
The traditional firetube utilizes a U-shaped tube inserted in the process vessel and burn casing gas to produce heat which in turn, is transferred to the fluids surrounding the tube. It is simple, effective and has always been done this way…. but not without issues. High surface temperatures, gasket and coating failures, non-uniform heating, localized stress at weld joints and marginal efficiency all lead to reduced life and failures.
Elite Indirect heating addresses these issues by removing the direct heat source from the process vessel and installing an external ASME certified boiler. This system produces a low-grade steam which is used to heat the process fluids while maintaining a separation from the heat source. The firetube is replaced by a steam bundle utilizing the existing firetube throat. This provides a lower temperature, uniform heat source to the surrounding fluids that is safe and efficient. Alternatively, an exchanger external to the vessel, can be used to heat the fluids through circulation. This method not only increases vessel volumes, but also eliminates heating efficiency issues caused by low production flow.

Electric or Gas? Choose the Right Indirect Heating System
Indirect heating technology can be powered by either gas or electricity, depending on operational needs and environmental goals.

Unprecedented Spacing Exemption
NORTH DAKOTA INDUSTRIAL COMMISSION REVIEW AND ORDER
October 24, 2012 NIDIC grants similar approvals that are standard in Saskatchewan CA By utilizing the CWT Indirect heating system you may now treat oil 21 feet away from the production tanks rather than the 125 feet from production tanks that is currently standard in ND today.
This was a very significant ruling for future activities.
Located outside the secondary containment in a General Purpose location.
This allows for direct heating of oil tanks or Heater treaters with low gas production. (GOR)
