Efficient Heat Transfer in a Compact Design

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.

Market Challenges
Rising demand for tenant space in commercial buildings and an ever-increasing focus on reducing energy consumption have created numerous challenges for designers and contractors. These challenges include the requirement for mechanical room optimisation and energy recovery or free cooling systems such as water-side economisers, geothermal heating/cooling and deep-lake water cooling. There is now, more than ever, a growing demand for compact heat exchangers capable of transferring heat at low approach temperatures to achieve greater temperature crossing, which saves energy. In addition, factors such as global warming, high frequency of building conversions, and tighter plant rooms have led to a demand for heat exchangers that can be maintained easily and are flexible with regards to future expansion.

Space Savings
Due to their higher heat transfer capabilities, Armstrong X- Series plate heat exchangers can take up less than other designs, yet provide the same or better performance. The X-series plate have an extremely efficient plate pattern that produces higher heat transfer coefficients, less heat transfer surface area required and a smaller footprint especially for HVAC applications. For a typical cooling application of 1500 kw, the SX90-2000 provides the most compact solution for a given capacity.
