o.d.t. Engineering is the regional representative for Drache Umwelttechnik, Germany.
Drache Umwelttechnik is a world leader in molten metal filtration, particularly in the aluminium industry. For many years Drache ceramic foam filters have been used all over the world under all conditions of molten metal filtration with great success.
To fulfil today’s quality demands for casthouse and foundry products, a high purity grade of metal quality is required. Even the smallest inclusions can lead to cracks, pinholes or poor surfaces and make the final product unusable.
o.d.t. Engineering offers high quality Drache ceramic foam filters in various sizes and porosity grades to suit your production requirement.
Drache’s Ceralu filters are manufactured in porosities from 10 to 70 PPI. Many industry standard sizes are available and custom-made cut-to-size filters are also possible.
The filters are placed in the melt usually inside a filter box. Complete metal filtration units with gas or electric filter tile pre-heat system are also available.
