Description

Seitz IR series depth filter sheets were developed to meet the production needs and requirements of the distilled spirits industry.

A visually bright finished product free from visible particles is one of the main objectives of spirits filtration. Components (C12-16 fatty acid esters, terpenes, proteins or their complex compounds with metals and/or phenols) of some spirits may precipitate if calcium ion levels are too high. Magnesium may also cause precipitations in tannin containing spirits like whisky and brandy. Standard filter sheets contain small quantities of these extractable ions from the raw materials. IR Series filter sheets undergo a proprietary treatment that results in extremely low levels of extractable ions making them the ideal solution for distilled spirits applications.
