500 René-Lesvesque: 27-storey office buildings
Problem: Pipes pierced, pipes blocked, $ 35,000 / year in chemicals. Solution adopted for catalytic treatment of 300 GPM installed in bypass to stop the bleeding. This resulted in savings of more than $ 500,000 resulting from an investment of $ 35,000 and an operating cost of $ 1,500 per year.
Serious problems in maintaining a maximum water temperature of 43°C (110°F) at the outlet of the bathtub faucet and showerhead. This situation put the residents' physical integrity at risk because of the possibility of burns.
Improve a 70-year-old hydronic heating system, is it possible without chemicals? The decision to install a catalytic treatment on the heating network resulted in permanent savings in chemicals, natural gas consumption, and maintenance and repairs. In addition, thanks to the descaling power of our catalytic technology, the network was completely cleaned during the first heating season. Since then, we have never had to change thermostatic valves or replace sections of piping. The heating system has been rejuvenated for 70 years, and it is still in operation after 20 years.

Thanks to the descaling power of our catalytic systems, the network was completely cleaned during the first heating season. In addition, the City has never had to change thermostatic valves or replace sections of piping. Although the winter of 2002-2003 was very cold, savings of 14% in m3 / d-d were achieved compared to 1998-2000. This percentage climbed to 18% in 2003-2004.
Maintaining the comfort of a building to satisfy all tenants was a challenge in itself. It was impossible to keep the chilled water temperature lower than 9ºC (48ºF) when it was to be at 5ºC (42ºF) for tenant comfort. The circulation of chilled water piping was so reduced because of limescale that we had to consider the replacement of the piping at great cost, a situation unthinkable for the owners who had to consider the displacement of several tenants during the works. with the risk of losing several.
Expenditures in excess of $ 2,000,000 were avoided for the replacement of piping and the loss of income to tenants who had left their apartments because of the proposed work. The results far exceeded the expectations of the owners and the maintenance manager.
