OnSite and OffSite Services.
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.
(1-2 Days) On or Offsite
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 is collected in the filter.*The level of success for this cleaning method is determined by the amount and type of contamination. If the scale has hardened, which is very common on heating applications, the chemical flush effectiveness can be limited.
(2-3 Days) On or Offsite
Recommended for heat exchanger tubes that have hardened scale, the bonnet must be removed. High pressure cleaning and/or Roto-Jet rods with cleaning brushes and drills are inserted into each tube to grind or cut away scale or contamination.
(2 – 3 Weeks) Offsite
Tube bundle or complete heat exchanger is serviced at one of our service facilities. A mild acid solution is pumped through the heat exchanger for 6-8 hours, during the flushing all debris is collected in the filter. Before and after flow rates are recorded to gauge the effectiveness of the cleaning.
Extreme fouling applications - tube bundle is submerged in a heated chemical bath.
After 4 hours the bundle is removed and high pressure washed.
If the contamination remains the process is repeated.
