Benefits
Cost Effective
In many applications, performance can be achieved by a single hairpin as opposed to multiple Shell & Tube exchangers, resulting in lower capital costs, as well as future maintenance.
Cyclic or Shock Service
Large-radius U-bends and all terminal connections located at the same end allows for more extreme thermal expansion without the need for an expansion joint.
Durable Baffle Cage
Baffles are welded to tie rods without “sleeves” or internal nuts.
Extreme Terminal Temperature Differential
Independent-tube sheets and closure components eliminate differential thermal expansion across a single-tube sheet design, as is typically encountered with conventional Shell & Tube.
High Pressure
Our unique closure technology allows for pressures exceeding 10,000 psi.
Large-Radius U-Bends
Easy to clean, and eliminates the need for expansion joints or packed joints.
Moveable Support Brackets
Allow shell expansion and contraction; eliminate sliding plates; slotted on all four sides for flexible installation and future additions.
Separate Tube Sheets
Handles high temperature differences and cycling more effectively.
Small Footprint
Due to the geometry of hairpins, the equipment takes up less space relative to the Shell & Tube alternative.
Temperature Cross
Ideal when a temperature cross exists, or a close temperature approach is desired due to its single-pass configuration that allows for true counter current flow.
