Shell & tube, shell & fin, gas cooler, and process heat exchanger equipment engineered and shop-built to ASME Section VIII Div. 1 and TEMA class, backed by an ISO 9001:2015 quality system from thermal design through hydrostatic test.
Fintelius fabricates the complete range of process heat exchange equipment — shell and tube exchangers, shell and fin units, gas coolers, air cooled condensers, tube bundles, steam air heaters, and inter/after coolers — alongside our flagship air cooled heat exchanger & fin fan cooler line. Every unit moves through the same disciplined path: thermal and mechanical design, code-qualified welding, and rigorous in-house inspection and testing before dispatch.
Design and fabrication capability spans carbon steel, stainless steel, duplex, nickel alloys, and other exotic materials, so a single accountable shop can cover a project's full heat exchanger scope — from a single replacement bundle to a complete multi-unit process package.
Every heat exchanger — whatever its configuration — follows the same controlled path through the shop.
Process duty is rated and the exchanger is sized — tube count, pitch, baffle spacing, and shell diameter — then mechanically designed to code.
Tubesheets are drilled and machined, shells rolled and formed, to the tolerances the thermal design demands.
Tubes are inserted, expanded or welded into the tubesheet, and baffled and supported through the bundle length.
Code-qualified welders complete shell, head, and nozzle welds; radiography, ultrasonic, and dye penetrant testing verify every joint.
Assembled exchangers are hydrostatically tested, stamped, coated, and prepared for shipment.
From flagship air cooled equipment to shell and tube process exchangers — sized, fabricated, and tested under one roof.

Accommodates differential thermal expansion between shell and tube bundle, and allows the full bundle to be pulled for cleaning — suited to fouling or high temperature-differential service.
Tubesheets welded directly to the shell for a simpler, lower-cost design where shell-side access for cleaning is not required and thermal differentials are moderate.
A single tubesheet with U-shaped tubes allows free thermal expansion of each tube and simplifies bundle removal for maintenance.
Machining, forming, welding, and testing equipment sized for process heat exchanger fabrication.
Precision drilling and machining of tubesheets to the tube layout and ligament tolerances the design requires.
Plate rolling and forming for shells, heads, and channel sections across a range of diameters and thicknesses.
Tube-to-tubesheet joints made by roller expansion, welding, or a combination, per the design specification.
Baffle plates and tube supports cut and fitted to control shell-side flow and prevent tube vibration.
Code-qualified welders and procedures across carbon steel, stainless, and alloy materials.
In-house and partnered nondestructive examination — RT, UT, MT, and PT — verifying every pressure-boundary weld.
Pressure-test stations sized for shell and tube exchangers up to large diameters and design pressures.
Post-weld heat treatment for code-governed material and joint combinations.
Surface preparation and protective coating applied to specification before dispatch.
Weld integrity across shells, heads, and tube-to-tubesheet joints confirmed by RT and UT before hydrostatic test.
Every exchanger is pressure-tested to design specification, shell-side and tube-side, prior to dispatch.
Tube count, layout, and material traceability verified and documented against the approved design package.
Process cooling, condensing, and intercooling duty across upstream gas processing and downstream petrochemical plants.
Turbine lube oil coolers, compressor after-coolers, and steam air heaters for power generation and gas compression trains.
Process cooling equipment for data center thermal management and industrial water treatment facilities.
