Plate heat exchanger

Armstrong’s gasketed Plate Heat Exchanger (PHE) product line includes more than 20 different models and offers numerous configurations, connections and material options, providing a superior heat transfer solution for any HVAC application.

Energy Efficiency

The Armstrong PHE Series achieves the highest efficiency and heat transfer rates by flowing the two media in opposite directions (counter-current) in a highly turbulent fashion. The temperature gain or loss between the hot fluid and the cold fluid at a given flow rate is the regeneration rate. With counter-current flows, high turbulence and optimized corrugation, Armstrong Series PHE units provide regeneration rates of up to 90%.

% Regeneration = ( Tin [hot fluid] - Tout [hot fluid] ) / ( Tin [hot fluid] - Tin [cold fluid] ) x 100

The X Series plates are specifically designed to produce the highest heat transfer efficiencies.

Armstrong PHE Series heat exchangers offer multiple plate geometries to provide the optimum heat transfer solution for a given application.

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 plate and frame heat exchangers as with shell and tube heat exchangers.  Professionally 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.
