Elite Thermal Systems

Overview

Swelling rate (increase in volume when heated) is an important indicator of the quality of coal for coking. It is determined by a standard dilatometric test.

In one measuring cycle, four samples can be measured.
Fully automated performance.
Auto-diagnostics of the equipment.

From the expansion curves the following numerical parameters of the tested coal samples are obtained.

Softening temperature.
Temperature of maximum contraction.
Temperature of maximum dilatation.
Value of maximum contraction.
Value of maximum dilatation.
