This patented DDT Process is the safest, most inexpensive way to clean heater tubes. DDT is the innovator and designer for the fire heater cleaning concept utilizing an ingenious polymer Pigg®.

The DDT Process employs a closed loop, self contained hydraulic system, making it a very safe and environmentally friendly system.

DDT holds 22 Patents World Wide and has also licensed the use of the technology to third parties.

It is the only technology that will remove every kind of deposit in all types of fired heaters. Because the DDT Process uses no chemicals and works at ambient temperatures, it can be used to clean convection sections, external crossover lines, coke transfer lines, and other sections that cannot be steam-air decoked.

Everything we do has a friendly impact on the environment.
