With 7 years of experience in cleaning fired heaters in 26 countries, DDT is the choice of refiners all around the world.

DDT can operate worldwide since they have agents with twenty night warehousing locations in eight countries. With the help from the agents and warehousing locations, DDT can have quick access to the necessary piggs and supplies to do the job.

D.D.T. manufactures pumping units and mechanical piggs at its Lacombe location, with shipping out on a global basis. The technology applied by DDT is extremely powerful; it can remove even the hardest coke and deposits of all types.

The person who invented the DDT patented pigg is Orlande Sivacoe, also the founder of Decoking Descaling Technology Inc.

The Pigg is controlled by the pumping units through out the cleaning process. Movement of the Pigg during cleaning is controlled by a pumping unit that uses pressurized water. DDT keeps twenty two patents on both hardware and process for decoking of fired heaters. The pumping units can vary in size, which includes small containerized units for easy transport to difficult sites, motorized truck mounted units (single pump), and multiple pass units which includes dual pass and four pass units for faster cleaning performance. When using DDT service, you can rest assured that all coke and deposits will be completely removed from your fired heater.
