• Ramsbottom Carbon Residue Apparatus

Ramsbottom Carbon Residue Apparatus

Determines the ‘carbon residue’ left after evaporation and pyrolysis of a sample oil in the Ramsbottom furnace, providing an indication of the deposit forming tendencies of fuels and guidelines for the processing of refinery products.

  • Conforms to ASTM D524 and related specifications
  • Microprocessor temperature control with digital display and over-temperature cut-off

Thermostatically controlled coking furnace for five samples. Cast-iron block type furnace reaches the standard test temperature of 550°C (1022°F) rapidly and controls with ±1°C stability. Microprocessor temperature control has °C/°F switchable digital setpoint and display. Operator and equipment are protected by an over-temperature control circuit which automatically interrupts power to the unit should the block temperature exceed the programmed cut-off point.

This unit replaces the K27100 & K27190 Ramsbottom Carbon Residue Units.
