 HEATER TREATERS The DPS Delta electrostatic heater treater is a horizontal unit designed and built to meet the requirements of international codes and standards, performing the following functions:-
The treater is skid mounted and complete with complete valves, instruments and accessories to ensure safe and reliable unattended operation.  The heating section of the treater comprises of a “U” Type firetube which is available with a gas or oil fired burner system and associated local control panel. The heater treater has an innovative coalescing section utilising both AC and DC voltage to enhance the coalescence of water droplets. The DC field between the electrode plates allows a uniform migration of water droplets towards the opposite charged electrode while maintaining an AC field between the water interface and the electrode plates to coalesce the larger droplets near the oil/ water interface.  The droplets passing between the two differently charged electrode plates collide, coalesce and then fall back into the water phase under gravity. An externally mounted transformer with internal diodes provides a secondary output voltage of 16.5/23.0/ 35 Kv DC to the electrode plates. The transformer has a 100% reactance which will allow, in the event of a water slug in the crude causing a short circuit, for the unit to be kept on line until normal conditions are reinstated.  We are able to execute projects throughout the world utilising our network of partnerships and joint ventures and in- country offices, thus maximising local content and transfer of technology.
