TFOT Bitumen Oven

The TFOT is a specialized laboratory oven used to determine the loss in mass and the effect of heat and air on a film of semi-solid bituminous materials. It provides a standardized simulation of the hardening that a binder undergoes during the mixing process in a typical asphalt plant.

Key Performance Features

  • Short-Term Aging Simulation: Specifically designed to evaluate the susceptibility of bitumen to aging and hardening through controlled thermal exposure.
  • Exceptional Thermal Stability: Features a high-quality stainless steel internal chamber with fiberglass insulation to maintain precise temperature uniformity.
  • Controlled Rotation: Equipped with a mechanical rotating shelf that operates at a steady 5 to 6 rpm, ensuring all samples are exposed to identical conditions.
  • Enhanced Safety: Built with a dual safety thermostat system to prevent accidental overheating and a double-glazed viewing window for safe monitoring.
  • Standards Compliance: Configurable with specific accessories to meet varied international protocols including ASTM D1754, AASHTO T179, and EN 12607-2.

Technical Specifications

  • Temperature Range: Adjustable from ambient to 200°C with high-precision digital control.
  • Chamber Construction: Internal chamber and shelf support made from corrosion-resistant stainless steel.
  • External Housing: Enameled steel frame designed for durability in heavy-duty lab environments.
  • Rotating Shelf: Supports multiple sample containers (e.g., 9 containers for Loss on Heating or 4 for Thin Film tests).
  • Power Requirements: 1300 W heating system with configurations available for 230V, 220V, or 110V.
  • Dimensions: Compact footprint with internal dimensions of 330 x 330 x 330 mm.
