This is a comprehensive maintenance service in which we take care of your plate heat exchanger as a complete unit.
HISAKA, the original manufacturer, performs all processes—including disassembly, inspection, cleaning, gasket replacement, frame maintenance, reassembly, and final inspection—to restore the unit to like-new condition.
Full Service Package for Plates
If the main unit is installed in a location where removal or relocation is difficult, a plate-only maintenance service is also available.
Optional Services
Dedicated returnable box
Return containers that precisely fit the plates that are currently in use are provided upon customers' requests. Simply send us the plates in the return containers, and we will send back cleaned plates.
Plate Disassembly and Pickup Service
We disassemble your PHE on site, and then reassemble it on site after maintenance.
