Applications

POLYBLOC heat exchangers series NC and NF are themost advanced design GRAPHILOR3 block equipment.The main features which stand out are their robust-ness, high mechanical strength, their exceptional long working life and reliability in service.They are the results of more than 30years ofresearch.Development and the experience gathered from over 10,000 units in operation in more than fifty countries throughout the world have made CARBONELORRAINE a world leader in the field of impregnated graphite equipment for the process industry. High chemical inertness/non-contaminating Ideal for use in heavy/fine chemical/pharmaceuti-cal/drug and food industries except for highly oxidis- ing conditions.Wide range of heat transfer areas: from 0.1m
2 to1,500m
