Gerstenberg Services

Gerstenberg Services – Your supplier of equipment and spare parts for the margarine industry

Gerstenberg Services was founded in 2013 and supplies innovative quality equipment of the Polaron series with outstanding features for production of margarine, shortening, ghee, low fat spreads, CBS, butter spreads, AMF, texturised butter and related products within the yellow fat and edible oil industry, based on long-term experience.

Our main machine is the Polaron scraped surface heat exchanger (SSHE) which is designed for direct cooling with the natural refrigerant CO2 and thus helps food manufacturers improve cooling capacity and reduce energy costs. The Polaron SSHE can also be supplied for cooling with NH3 or R507.

Our Polaron series also comprises high pressure pumps, pin rotor machines and pilot plants.

In addition, we offer a wide range of spare parts for Perfectors and other existing Gerstenberg equipment, all in redesigned and improved version and in more durable materials. Although the parts have been redesigned and materials have been changed the parts are still fully interchangeable with standard parts.

Margarine & shortening service

We also offer preventive maintenance, service overhauls and onsite refurbishment of existing equipment. All materials in contact with the product are food-approved and fully traceable.


Gerstenberg Services was founded as a subsidiary to Gerstenberg & Agger which has existed since 1901 when it was founded by the two engineers Aage Gerstenberg and Christian Agger. In 1916 the Gerstenberg family became the sole owner of the company, which in the first few decades primarily earned its money as consulting engineers.
In the subsequent decades Gerstenberg & Agger specialised in the development, production and installation of equipment for the food industry, and at the end of the century the company was the leading manufacturer of food processing plants in the world.

In 2004 Gerstenberg & Agger acquired Schröder GmbH. The year after the two companies merged all main activities and transferred them to the new subsidiary Gerstenberg Schröder which was sold to SPX Flow Technology in 2010.

In 2013 a new subsidiary to Gerstenberg & Agger, the company Gerstenberg Services, was formed to provide future and former clients with new products and spare parts.
