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 GEA Group AG 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.
Acceptance of incoming service goods in order to maintain a high quality manufacturing facility and provide a safe and healthy environment for our personnel, GEA Bloksma has established regulations governing the acceptance and handling of incoming service items.
Incoming service items will be inspected prior to unloading. Items that do not comply with these regulations will be rejected and returned to the customer at the customer's expense.
Customers sending items to GEA Bloksma's repair facility should first take care that the following regulations are adhered to:
Heat exchangers must be empty of fluids:
- All heat exchangers must first be completely emptied, sealed and must not contain oil or other fluid what so ever
- Heat exchangers must be sealed with appropriate steel flanges with gaskets and threaded pipe plugs as required to prevent any possible leakage
Heat exchangers must be cleaned:
- All coolers must be cleaned prior to shipping to GEA Bloksma's repair facility for reasons of safety and to enable proper inspection and diagnosis
- Heat exchangers will only be accepted accompanied by a formal certificate stating that the item has been thoroughly cleaned and contains no hazardous fluids or materials
- If coolers arrive at GEA Bloksma's repair facility without having been thoroughly emptied and cleaned, GEA Bloksma will either reject the shipment or charge the customer for cleaning of the items and disposal of any hazardous fluids
Heat exchangers must be properly documented:
- To best enable GEA Bloksma to provide excellent customer service and response all service goods must be shipped to Blokma's repair facility properly marked to indicate the origin and accompanied by specific instructions as to the requested repairs or issue with the item
- Incoming service items arriving without proper markings indicating customer and application and additional instructions will be rejected and returned to the customer at the customer's expense
Incoming service items that comply with the above requirements will be received by GEA Bloksma for evaluation, diagnosis and repair as required. Prior to undertaking any repair work or service, GEA Bloksma will provide the customer with a thorough evaluation report and recommendations for the repair, overhaul or replacement of the item.
If a customer decides not to repair a service item received and evaluated by GEA Bloksma, the customer must arrange for the item to be removed from GEA Bloksma's repair facility in a maximum of 3 weeks time.
If service items are not picked up within this time period, GEA Bloksma is entitled to scrap goods and retain any proceeds from doing so.
If a customer decides to replace a service item received and evaluated by GEA Bloksma instead of repairing the original, this original service item will become property of GEA Bloksma, unless the customer clearly specifies otherwise.
