Nofitech acquires CM Aqua Technologies and Rats Aqua & Polymer Technik

Nofitech Holding AS acquires CM Aqua Technologies ApS in Denmark and Ratz Aqua & Polymer Technik GmbH with subsidiary Hex Filter GmbH in Germany.

Water treatment suppliers CM Aqua and Ratz Aqua have been acquired by Nofitech Holding AS. Part of the transaction is paid by shares in Nofitech Holding AS, so that the four owners of CM/Ratz become shareholders in Nofitech Holding AS.

CM Aqua and Ratz have been co-operating for several years with production at Ratz’ factory in Remscheid, near Düsseldorf in Germany. The main products for RAS-plants are HEX drum filters, GALAXY protein skimmers, Oxywise oxygen generators, and AL2 belt-filters for sludge systems. CM Aqua, located in Farum, Denmark, is handling sales, service, and support with technical teams in Denmark and Ukraine.

CM/Ratz has delivered more than 600 HEX filters to RAS plants, aquariums, and pools around the world, as well as equipment to de-licing barges and water treatment systems to well-boats.

Managing Directors Kurt Carlsen (CM Aqua) and Andre Pechura (Ratz) are delighted with this merger which gives CM and Ratz financial strength to take on even bigger projects globally, and access to Nofitech’s R&D competence.

Nofitech’s ModulRAS facilities have been designed from the beginning for both seawater and freshwater usage and have HEX filters installed in all units. Robert Hundstad, CEO of Nofitech, looks forward to co-operating more closely with the new sister companies and together improve the product range to include other cost-efficient solutions and pre-manufactured modular sections.

CM and Ratz market and sell their products to more species than the only salmon and this should open further opportunities for Nofitech’s ModulRAS says Asbjørn Reinkind, chairman of Nofitech Holding. The companies will operate independently and CM/Ratz will continue to serve other RAS suppliers.

ModulRAS for post-smolt is delivered in different sizes with 4 octagonal tanks with a diameter up to 20m and 6,6m deep. This gives a rearing volume of 9.200m³ and daily feeding capacity up to 8.000kg. The tank walls function as walls, both for the water treatment and as the outer walls of the module. This gives a very cost-effective and compact solution with a limited footprint. Nofitech delivers a comprehensive and standardized training program for all employees operating the modules.
