As a heat exchanger becomes fouled with dirt, debris or scale, often the modulating valve provides additional hot or cold liquid to help compensate for the loss of efficiency of the heat exchanger.
Over time the control valve will continue to open fully. Unfortunately, on the hottest or coldest days, even with the valve fully open the heat exchanger cannot meet the thermal transfer requirements and the situation becomes critical.
Monitoring just the operating temperature provides a false sense of security. Recording the difference in the outlet and inlet pressures provides a more accurate result of the amount of fouling.
Fouling equal to the thickness of a piece of paper represents a 20% loss of thermal efficiency. In addition, the energy cost for pumps increases since the pump must work harder to overcome the increased pressure resistance through the PHE
T.H. Industrial Solutions Inc. (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.
Today there are fewer qualified people in this industry that know the products and understand the applications. Utilizing hands on experience and knowledge that has been gained by our THS sales and service technicians for over the past 30 years, we will take the time to understand what you require and strive to provide a prompt, educated and accurate response at a competitive price.
