Groku acquires Harstra Instruments

Groku from Kampen has fully acquired Harstra Instruments from Zeewolde. Harstra manufacturers cleaning equipment and drying cabinets for the safety technology industry. Due to the similarity between production methods and the diversification of end markets, Harstra is an important addition to Groku.

Harstra, founded in 1940, originally focused on the development and production of scientific instruments. Over time, the focus has shifted from laboratory instruments to developing and producing solutions for the safety technology industry. The company's two main products are drying cabinets and cleaning machines for cleaning air masks and equipment, which can then be dried in a range of drying cabinet models. In this niche, Harstra has a global customer base that includes fire brigades and industrial safety services. Harstra has a location in Zeewolde where the products are manufactured, assembled and tested.

Groku has acquired the shares from Roland van der Ham and Jolanda Van der Ham-Gerritse. Roland took over his father's company in 1983 and Jolanda became involved with Harstra in 1996. They will transfer their work to Groku employees in the coming period. Groku will ensure to continue to deliver the quality and service level that Roland and Jolanda achieved with Harstra Instruments.

Anders Invest, together with director Karl den Besten, has been a shareholder of Groku since 2018. With the addition of Harstra, it broadens both its portfolio and geographical end markets.
