Spiral tube type heat exchangers are fabricated from coiled tubing. In some cases the tubing is installed inside a fabricated bundle to provide a compact stand alone heat exchanger. These exchangers are used primarily for small services such as pump seal fluid and sample coolers. Advantages

Spiral plate heat exchangers are fabricated from two metal plates that are wound around each other. One process fluid stream enters the exchanger at the centre and flows outwards while the second fluid enters on the outside and flows inward. This creates almost a true counter current flow. Advantages Typical Applications

Advantages Very compact design High heat transfer coefficients (2 – 4 times shell & tube designs) Expandable by adding plates Ease of maintenance Plates manufactured in many alloys All connections are at one end of the exchanger Good temperature approaches Fluid residence time is very short No dead spots Leakage (if it should occur) is...

A plate and frame heat exchanger is a compact heat exchanger where thin corrugated plates are stacked in contact with each other, and the two fluids flow separately along adjacent channels in the corrugation. The closure of the stacked plates may be by clamped gaskets, brazed (usually copper brazed stainless steel), or welded (stainless steel,...

The hairpin heat exchanger design is similar to that of double pipe heat exchangers with multiple tubes inside one shell. The design provides the flexibility of a U-tube design with an extended shell length that improves the exchanger’s ability to achieve close temperature approaches.   Advantages Good counter current or co-current flow –...
