The Hair pin Type Heat Exchanger is a true counter-current flow and are especially suitable for extreme temperature crossing, high pressure, high temperature, and low to moderate surface area requirements. Hairpin heat exchanger designs can increase heat transfer coefficients in single-pass process streams with high temperature differentials.Heat exchanger consists of a pair of concentric tubes. One of the fluids used for heat exchange flows in the inner tube, and the other in the annular space between the two tubes.Our Hairpin Exchangers are available in single tube (Double Pipe) or multiple tubes within a hairpin shell , bare tubes, finned tubes, U-tubes, straight tubes, fixed tube sheets and removable bundle. Hairpin heat exchangers utilize true counter-current flow. When a process calls for a temperature cross, a hairpin heat exchanger is the most efficient design, with fewer sections and less surface area. Hairpin heat exchangers offer the mechanical and maintenance engineer advantages inherent with their design.

Hair Pin Type Heat Exchanger Advantages

• Lower cost
• Mobile exchanger
• Small size and good position in the vat
• Good heat exchange coefficient
• Little fur deposit thanks to the polished finish
• Good fluid circulation in the tube
• Vinification of reds or whites
• Independent tubesheets for high terminal temperature differences.
• Thermal shock.
• Cycling.
• Long radius U-bends for effective thermal expansion.
• High temperature differences.
• Ease of cleaning.
• All-welded baffle cages for durability.
• High pressure closures for pressures
• No internal bolting.
