EKasic^® SILICON CARBIDE PLATE HEAT EXCHANGERS

Pfaudler and ESK’s plate heat exchanger is made of sintered silicon carbide advanced ceramic to resist extremely corrosive media and particle-loaded erosive liquids.

Properties

EKasic^® silicon carbide plate heat exchangers are used in the chemical industry or similar sectors, especially where highly corrosive media are heated and cooled, or must be evaporated and condensed. The EKasic^® silicon carbide plates resist acids, alkalis and hot water. EKasic^® SiC is also extremely hard and wear resistant. It does not release either particles or metal ions. EKasic^® silicon carbide plate heat exchangers are available in three versions: sealed, semi-welded and as a hermetically sealed monolithic block.

The material is approved for drinking water applications according to FDA, KTW, WRAS and Fresenius, and is also harmless for food-contact applications.

Together with the excellent thermal shock resistance of EKasic® silicon carbide, ESK plate heat exchanger have long service lives, high safety and improved product quality.

The plate heat exchanger with the patented ESK design operates standardized on the counterflow principle. The ESK plate design was specially tailored for liquid media by means of computational fluid dynamics (CFD) simulations. It is capable of outstanding heat transfer rates with minimum pressure loss. The outstanding thermal conductivity of the very lightweight EKasic^® SiC permits very high thermal efficiency. The dimensions and weight of the EKasic^® silicon carbide plate heat exchangers can be kept amazingly small, making the apparatus extremely compact.
Either DIN or ANSI flanges can be used for connection. The B260 and B500 series products were designed especially for heat transfer between liquids with a pressure difference of up to 16 bar.
Compact plate heat exchangers can transfer up to 700 kW with an extremely small footprint.

Individual design of the heat exchangers is carried out with the AD2000 standard and with a specific developed ESK software.

Processing

ESK plate heat exchangers meet demands for robust design, customized performance and ease of maintenance. They operate without gaskets as a hermetically sealed monolithic block. This design provides high reliability for use with highly dangerous substances. All designs can work with pressure differences up to 16 bar. Risk of fouling is extremely low. EKasic^® silicon carbide plate heat exchangers also make thing easy when cleaning-in-place is necessary. Complete drainage for maintenance and cleaning is possible at any time without dismantling.
