Our history


Founding of Blokland Non Ferro

Our founder Jan Blokland started building yachts together with his brother Wim Blokland in 1962. The brothers were innovative and started to produce and use small heat exchangers and other products in their yachts. As a result, other companies started to inquire and order these small heat exchangers as well as other products.


Acquiring Non Ferro Gieterij

The brothers Blokland acquired the Non Ferro Gieterij (foundry) in 1969. Blokland started to develop and manufacture marinization parts for diesel engines. The production and development of shell & tube heat exchangers still continued. After a few months, the brothers Blokland decided in favour of splitting the company and Jan Blokland continued with Blokland Non Ferro.


First expansion

In the mid of the 1970’s it was time for the first expansion. The expansion was necessary for the growth of both work and personnel.


Design & Production

At the beginning of the 1980’s the design and production of the box coolers as well as propeller shaft systems started. Both products would turnout into a great success. The picture shows Jan Blokland machining parts for a propeller shaft system at younger age.



Another expansion of the Blokland premises was realized in 1983.


Renewing the building halls

One of the earlier built building halls has been renewed in 1993. The picture shows Jan Blokland together with his daughter Corine.

Acquired Amartech

Amartech was acquired in 2014, causing the capabilities of the propulsion department of Blokland Non Ferro to increase significantly.


Two new building halls

Two new building halls were realized in 2017. The new production halls were necessary for the increased activities of the departments propulsion and repair/cleaning of coolers.


Exalto propulsion

The machine shop, personnel and know-how of Exalto propulsion were acquired by Blokland Non Ferro in 2018. Accordingly, the entire machine shop of Exalto was transferred to the workshop in Sliedrecht.



The activities of VMtech (Aart Vermeij) were taken over by Blokland Non Ferro in 2019. VMtech was mainly specialised in the design and supply of Rubber Bearings and Lost Wax Metal Castings.


Product groups bearings

In 2021 Blokland Non Ferro acquired the product groups bearings, cap nuts and deck caps of Bonsink Aquaservice. The products became part of Blokland's propulsion program.
