If you've been opening and closing your plate heat exchangers with pipe wrenches, slugging wrenches or similar tool, you may want to consider a ratcheting type spanner wrench. These heavy duty tools can make the job go a lot easier and they can be used in a variety of applications.
Our most popular size is the 80mm, which also fits a heavy hex nut for 2" diameter threaded rod (3-1/8" across the flats). This size fits many of the larger Alfa Laval models that use 1-1/2" or 2" diameter closing bolt sizes.
For clients that have a variety of heat exchanger models, a single unit with smaller nut sizes or another application in mind, we provide reducing inserts in the following sizes :
Please contact the WCHE Service Centre for new reducing insert sizes that will soon be available.
