Key facts
FactDetails
Legal entity scopeOertzen is treated here as a brand, not as a currently separate operating company. Historic official materials name von Oertzen GmbH in Ammersbek, while Hako's sustainability report states that a merger with von Oertzen GmbH took place in 2023 and current Hako product pages market Oertzen equipment through Hako GmbH. Buyers should verify the current contracting, manufacturing, export, warranty and service entity for their order.

Company & Ownership

Hako's sustainability report says the merger with von Oertzen GmbH in 2023 added waterjet products to Hako GmbH's range. Current Hako pages market Oertzen high-pressure cleaners through Hako GmbH, and Hako is wholly owned within the Possehl Group. Historic Oertzen company references should therefore be distinguished from the present Oertzen brand and Hako operating responsibility.

Parent company: Hako GmbH

Ownership & entity evidence
Oertzen brand former von Oertzen company Hako operator and Possehl ownership boundary
Hako reports a 2023 merger with von Oertzen GmbH and now markets the Oertzen range, so the brand should not be presented as a separate current company without fresh registry evidence.

Competitive Position

World Clean Biz assessment: Oertzen adds specialist professional and industrial waterjet depth to Hako's broader cleaning platform. Buyers should focus on engineered application fit and distinguish the historic von Oertzen company from the current brand, Hako operator and local export-service chain.
