Drilling Fluids

http://schema.org/OutOfStock

The 4-Roller Oven is an effective aid in determining the effects of temperature on drilling fluid as it circulates through the well bore. The roller oven is designed to provide heating and rolling functionality simultaneously or independently. This oven can hold six 260-mL Aging Cells or three 500-mL Aging Cells.

Patent Number 4,677,843

Features

  • Variable-speed controlled
  • Enclosure is constructed of stainless steel for longer life
  • Stainless steel rollers promote a cleaner environment inside the oven
  • Glass-impregnated Teflon® roller bearings extend the life of the rollers and allow for longer maintenance-free service
  • Digital temperature controller that can be read directly from outside the oven
  • Temperature is controlled by an electronic solid state thermostat and operates between 100°F and 500°F (38°C - 260°C)
  • Circulating fan greatly improves air circulation within the oven and provides more stable, consistent, and reliable heating
