Special Dismantling Jig
Koch Heat Transfer Company S.r.l. has developed a unique, proprietary jig assembly designed to facilitate dismantling and reassembling operations of LUMMUS ADVANCED BREECH-LOCK EXCHANGER® heat exchangers. With the IMB™ jig it is possible to open the channel, remove the internals, and then reassemble and reclose the LUMMUS ADVANCED BREECH-LOCK EXCHANGER® heat exchangers in a very short time without the need for heavy cranage.
The jig’s sophisticated design includes ball bearing supports, fine pitch adjustment screws, and perfectly machined mounting/contact surfaces. All of this, together with its ergonomic design, makes the IMB™ jig the best tool of its kind for LUMMUS ADVANCED BREECH-LOCK EXCHANGER® heat exchanger maintenance.
The jig is mounted on a machined surface on the channel of the exchanger. This allows autonomous operation with no need for other plant facilities, such as cranes, etc. Once the jig is lifted and positioned on the mounting surface, opening the channel and removing the threaded ring and cover takes approximately 10 minutes. The entire sequence of activities, from completion of shutdown to full disassembly of the internals, can usually be performed in one to three hours depending on the size of the exchanger.
A different version of the IMB™ jig is also available for use with vertical arrangement of the LUMMUS ADVANCED BREECH-LOCK EXCHANGER® heat exchanger
