Delta T calculation for plate heat exchangers
... The maximum flow rate usually determines which type of heat exchanger is the appropriate one for a specific purpose. Alfa Laval plate heat exchangers can be used for flow rates from 0.05 kg/s to 1,000 kg/s. In terms of volume, this equates to 0.18 m³/h to 3,600 m³/h. ...
