Porvair acquires German molten metal specialist Drache for EU20.5 million to strengthen two leading aluminium filtration technology specialists

SELEE Corporation and Drache GmbH are now one.

Porvair PLC has said it has agreed to buy German molten metal filtration specialist Drache Umwelttechnik GmbH for €20.5 million in cash. The Norfolk, England-based environmental and specialist filtration technology firm said Diez, Germany-based Drache develops, manufactures and distributes filters, consumables and equipment for the molten metal industry and is a ‘leading supplier’ to the aluminium filtration market.

Drache will join Porvair’s Metal Melt Quality division under its existing management team.

Porvair said Drache will further strengthen its aluminium offering, following the previously announced £5.5 million investment to update and expand the cast house capabilities in Hendersonville, US.

The €20.5 million consideration is on a cash free, debt free basis and will be funded from Porvair’s existing cash reserves and banking facilities. The consideration includes around €4 million for two freehold operation sites in Diez, Germany.

In 2025, Drache’s revenue was around €20 million. Porvair expects the acquisition to be earnings enhancing in the 12 months to the end of November 2026. Porvair said it will have a ‘modest’ net cash position after the acquisition is completed.

“We have known the business for many years, and it is a strong strategic fit with our Metal Melt Quality division, bringing an extended geographical reach to the division’s existing businesses in the US and China, an enhanced product portfolio in the growing global aluminium market and additional manufacturing flexibility,” said Porvair Chief Executive Hooman Caman Javvi.

SELEE Corporation, which was acquired by Porvair in 1995, is a technical materials company specialising in the design and manufacture of porous ceramics for a wide range of demanding industrial applications.

Watt Jackson, Managing Director of Porvair’s Metal Melt Quality Division, noted that: “The combination of SELEE and Drache is a natural fit with significant benefit to aluminium cast houses worldwide.”
