| COMBINED UNIT Combined units POLYBLOC heat exchangers series NC/NF may be equipped with several kind of headers or distribution chambers enabling a direct connection to process units. They may be used in particular, as total flow condensers or as integrated reboilers. For example reboilers operating as phosphoric acid concentration are often equipped with special rubber lined steel connecting cones for larger size pipework. Units for quick opening When the process side of the heat exchanger requires easy access the unit can be fitted with a special process header for quick opening and dismantling without untightening and disturbing the stack of graphite blocks and gaskets. For larger size units the header can be supplied with a manhole. |
