Heat Exchanger Ontario, a division of T. H. Industrial Solutions Inc.'s (THS) has been servicing industrial heat exchangers and solving process problems across Canada since 2009. THS head office is located in Pickering, Ontario with a 6,000 square foot service center in Hamilton, Ontario.

will Disassemble and then Tighten a PHE to OEM Specifications
A portable chemical flushing unit consists of a pump, tank, filter and hoses. THS service technicians pump a citrus based cleaning chemical or mild acid solution through the heat exchanger for 6-8 hours. During the flushing any debris or contamination is collected in a bag filter with a magnet.*The volume and velocity of the pump package is limited, PHE’s over 3 ft in height and with connections over 2", will not experience significant benefits using this sized pump package since most power supplies available are 120V
Clip or ball style gaskets can be replaced onsite during service. The most effective method to remove glue style gaskets is to complete the service offsite. Plates are submerged in either a caustic acid bath or nitrogen to break the glue bond. Plate and/or gasket delivery when in stock is typically 1-3 weeks. Custom is approximately 6-12 weeks as they must be molded and/or stamped.*Chances of a PHE leaking increases to 50-60% probability when re-assembling a unit using gaskets that are over 10 years old, visibly damaged or brittle, causing the PHE not to seal completely. In addition, each time a PHE is taken apart the gaskets can be potentially damaged or may not reseat correctly when retightened.
accessibility to mechanical rooms is often severely limited
