Plate type heat exchangers

Plate type heat exchangers: Plate heat exchangers are composed of many thin, slightly separated plates that have very large surface areas and small fluid flow passages for heat transfer. Advances in gasket and brazing technology have made the plate-type heat exchanger increasingly practical. In HVAC applications, large heat exchangers of this type...

Microchannel heat exchangers

About Microchannel heat exchangers: Microchannel heat excahngers are heat exchangers in which (at least one) fluid flows in lateral confinements with typical dimensions below 1 mm. The most typical such confinement are microchannels, which are channels with hydraulic diameter  below 1 mm. Microchannel heat exchangers can be made from metal,...

Direct contact heat exchangers

About Direct Heat Exchangers: Direct contact heat exchangers involve heat transfer between hot and cold streams of two phases in the absence of a separating wall. Thus such heat exchangers can be classified as: Gas – liquid Immiscible liquid – liquid Solid-liquid or solid – gas Descripition: Most direct contact heat exchangers fall under the...

Phase-change heat exchangers

About Phase-change heat exchangers: Phase-change heat exchangers is to heating up or cooling down fluids in just a single phase, heat exchangers can be used either to heat a liquid to evaporate (or boil) it or used as condensor to cool a vapor  and condense  it to a liquid. In chemical plants  and refineries ,reboilers  […]

Dynamic scraped surface heat exchanger

ABOUT DYNAMIC SCRAPED SURFACE HEAT EXCHANGER: Dynamic scraped surface heat exchanger is mainly used for heating or cooling with high-viscosity products, crystallization  processes, evaporation  and high-fouling applications. Long running times are achieved due to the continuous scraping of the surface, thus avoiding fouling and achieving a...
