The ratcheting-type spanner wrench is specifically designed for opening & closing plate heat exchanger frames. These heavy duty tools make the job go a lot smoother by being non-slip and interchangeable from either direction. They can also be used in a variety of other applications.
Our most popular size is the 80mm, which fits a heavy hex nut (3⅛” across the flats) for a 2″ diameter threaded rod. This size fits many larger Alfa Laval models that use 1½” or 2″ diameter closing bolts.
Spanner Wrench Inserts
For clients with a variety of heat exchanger model sizes in their facilities, WCR offers spanner wrench inserts. The inserts consist of high-strength steel meant to withstand the demand of heat exchanger tightening and decompression. Inserts allow a single wrench to be utilized for multiple applications.
