The product is modified on the basis of the cylindrical block hole type graphite heat exchanger, the structure and principle are similar to the shell & tube type graphite falling film absorber, only the absorption, cooling and separation parts are composed of cylindrical block hole graphite condenser. In addition to the characteristics of shell & tube falling film absorber, the cylindrical hole type graphite falling film absorber has the advantages of high structural strength, good thermal shock resistance, high mass and heat transfer efficiency, and convenient maintenance.

Design parameters: Design pressure: 0.6MPa ; Design temperature: -20~165 ℃ ; Heat transfer area: 10~800 ㎡.
