Pieter Bloksma - A coppersmith by profession.
In 1920 Bloksma was founded by Pieter Bloksma, a coppersmith by profession. He started up his business in a small cellar, located in the centre of Amsterdam (The Netherlands), repairing radiators. After a few years he began, together with four of his sons, the production of radiators. In the thirties a complete network of workshops was founded by Bloksma.
At the end of the forties Bloksma started the design and production of shell & tube heat exchangers. Production facilities were moved from Amsterdam to Diemen for air-cooled heat exchangers and Zutphen, where the production of shell & tube type coolers was concentrated.
In 1979 Bloksma moved and concentrated the production in Almere, located in the centre of the Netherlands.
Since 2008 Bloksma has been a part of the worldwide acting Kelvion Group in Bochum, Germany, and is now named GEA Bloksma B.V.
Bloksma has built up a respected name in the field of heat exchangers for oil, water and air purposes for a variety of applications such as diesel engines, gearboxes, hydraulics booster- and separator modules, turbines, transformers and compressors.
