Appareil d'essai de résidu de carbone

Ramsbottom des produits pétroliers

ASTM D524, D6074; IP 14; ISO 4262; FTM 791-5002; NF T 60-117

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.

  • Ramsbottom Carbon Residue Apparatus
  • Conforms to ASTM D524 and related specifications
  • Microprocessor temperature control with digital display and overtemperature 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 overtemperature control circuit which automatically interrupts power to the unit should block temperature exceed the programmed cut-off point.

Communications software (RS232, etc.), ramp-to-set and other enhanced features are available as extra cost options. Contact your Koehler representative for information. Heavily insulated stainless steel cabinet with three-layer refractory top provides excellent heat retention.
