SERIES M
Applications
Series M POLYBLOC heat exchangers are the mostextensively used GRAPHILOR block units.Built for the first time in 1953 following the patentingof a novel idea, they have been constantly improved
and several thousands are in continuous operation in
more than 50 countries.Their distinguishing features are their robustconstruction, exceptionally long working life and
reliability in service.They are ideal for all applications in the chemicalindustry except in highly oxidising conditions.Their original design provides exceptional thermalefficiency, especially at low speeds or with viscous
fluids.The POLYBLOC modular design — especially the GMtype — is very versatile. The user may increase or
reduce the heat transfer area during the operation to
meet his needs at very low cost..They are particularly suitable as multi-purpose units inthe fine chemical and pharmaceutical industries.Easy dismantling makes them well suited toapplications where fouling and deposits are likely to
occur.Heat transfer surfaces range from 0.1m
2 to 65m
2 ata maximum operating pressure of 6to 8bars,
according to the type. POLYBLOC HEAT EXCHANGERin GRAPHILOR SERIES M
