Inert gas tests

Drying ovens with nitrogen blow

The European norm ISO 589:2003 Hard Coal – Determination of Total Moisture ensures samples are dried between 105 C – 110 C in a drying oven featuring nitrogen blow possibility with flow equal to about 15x capacity of the oven per hour.

Available models

SLWN1 – laboratory oven with dry nitrogen blow system of the chamber; the kit includes connections, valves and a laboratory rotameter (which can be calibrated)
SLWN2 laboratory oven with dry nitrogen blow system of the chamber; the kit includes connections, valves and a tech rotameter (which cannot be calibrated)

Available chamber capacity:

15l (SLWN1 15, SLWN2 15)
32l (SLWN1 32, SLWN2 32)
