Tube in tube heat exchangers, otherwise known as monotubular heat exchangers, are made of two stainless steel concentric tube with a non removable inner tube. The heating or cooling media will pass through the orifice between the two tubes, whereas the product would pass through the inner tube. The tubes are corrugated to offer turbulent flow, thereby maximising heat transfer and efficiency. These corrugated tube heat exchangers can be ordered with the specifications below, but can be dimensioned to meet your requirements.
