Scraped surface exchangers

Applications of the BORSIG scraped surface exchangers include de-waxing of lube oil, the oil separation from waxes, the production of cellulose acetate flakes, the manufacture of fatty acids, the crystallization of paraxylene, the continuous mixing of liquid and semi-solid products under cooling or heating conditions, heat transfer in the presence of strong product contamination of transfer surfaces as well as heat transfer with high-viscosity products.

 

The BORSIG scraped surface exchangers are designed and built for an optimum solution with regard to the intended application. For solving these problems BORSIG disposes of a modern data processing center. We are always prepared to assist you with our advice, even in the planning stage.

 

BORSIG Process Heat Exchanger GmbH supplies scraped surface exchangers for any desired throughput and thermal capacity with inside tube diameters of 6 inches, 8 inches, 10 inches and 12 inches.

 

Design and calculation can be based on the national standards applicable at the place of installation. Due to the special design of our scraped surface exchangers the maintenance intervals could be extended to 50,000 hours. Furthermore, relubrication of the antifriction bearings is not required within this period.

 

Scraped surface exchangers are provided for outdoor installation and therefore do not require a special building for protection against atmospheric influences.

 

Scraped surface exchangers with direct evaporation of a refrigerant in the jacket space of the double-pipe elements can be  supplied as cascade, thermosyphon or forced circulation systems, permitting the utilization of all types of refrigerants commonly used.

 

Prior to leaving our works, each scraped surface exchanger is subjected to a mechanical test run at operating pressure.

 

The instructions required for proper installation, startup, servicing and maintenance are set forth in an operating manual which will be supplied for each scraped surface exchanger.
