Preventing energy from evaporating into thin air

The Indian company Thermax supports operators in using resources more efficiently, thereby reducing costs and environmental impact. For example, Thermax manufactures heat recovery steam generators (HRSGs) that extract energy from turbine exhaust gases and increase turbine efficiency. Fabric expansion joints are crucial components in HRSGs and have to withstand temperatures of up to 600 °C. When selecting suppliers for an important export project at a petrochemical plant in Nigeria, Thermax did not want to take any risks – and went for tried and tested expansion joint solutions from EagleBurgmann.

A Partnership to build on

Our modern civilization is quite literally built upon cement. Today, building materials made from cement are used in buildings, roads, bridges, dams etc. Cement production is a heat-intensive process and causes thermal expansion in duct systems. To compensate this, Indian cement producer Ramco Cement needed fabric expansion joints with a diameter of several meters for two of their plants. On the basis of a close collaboration, EagleBurgmann was able to design components that increase the efficiency of the plant in the long run.

Rotates silently and unobtrusively

Sealing the agitator shaft of a mobile vessel is a very special task when dealing with a process in vaccine production. Liquid lubricated seals offer the best conditions for this application. However, the operation of dry contacting seals is more convenient and just as reliable as it is safe.

EagleBurgmann offers reliable sealing solutions for the production of shampoo.

Whether it’s for more volume, for more sheen, for dyed hair or for a well-groomed beard – the choice of shampoos seems practically endless nowadays. Only few people ever think about what happens before their favorite product is placed on the supermarket shelf. The production of hair wash products can be a great challenge for cosmetics companies. A variety of raw materials with different physical and chemical properties has to be processed. Canan Kozmetik, a sub-brand of L’Oréal based in Istanbul, faced a long period of constant downtimes and high maintenance costs due to seal failures. A solution was found by experts from EagleBurgmann in the form of cartridge seals with the innovative DiamondFace® Technology.

Separation seal breakthrough improves UK gas grid compressor reliability

The reliability of centrifugal compressors in gas grids are of the highest social and economic importance for network operators. Compressor performance and availability are closely related to the effectiveness of sophisticated compressor shaft sealing technology. Here, EagleBurgmann developed a new sealing concept which ensures better compressor availability: the coaxial separation seal CobaSeal.

Robust component in ensuring sterile vaccine production

In the highly sensitive production of vaccines, only a few barrier media and materials are approved for mechanical seals. If steam condensate is to lubricate silicon carbide sealing surfaces, premature wear is inevitable. How it actually does work is demonstrated by the case of an internationally operating pharmaceutical company.

10 years ahead

Between June 2017 and March 2019 the Hengli Group constructed an integrated refining and chemical complex in the Chinese harbor town Dalian where 20 million tons of crude oil are processed every year. EagleBurgmann advised the company Hengli concerning the selection of mechanical seals and supply systems for the whole plant and supplied more than 95 % of the components in use.
