Petropedia explains Hot Oiler

Hot Oilers are specialized units that are used to circulate the heating fluids carried through the production tubing. Pumps are the most important part of the units as they help in pressurizing the fluids to the tanks or tubing. The oilers also remove and dissolve paraffin deposits and are positioned to adapt fluctuating temperatures and materials. Apart from melting the wax, Hot Oilers are used for a variety of purposes such as:

  • Suppling hot water during oil spill cleanup
  • Heating motor oil present in huge engines
  • Heating fractured fluids defrosting water pipes
